Abstract: We evaluated sexual dimorphism in puparia of four whiteflies, viz., Aleyrodes sp. on Oxalis corniculata (Oxalidaceae), Bemisia tabaci (Gennadius, 1889) on Solanum melongena (Solanaceae), Dialeurodes delhiensis David & Sundararaj, 1992 on Ficus virens (Moraceae), and Trialeurodes vaporariorum (Westwood, 1856) on Phaseolus vulgaris (Fabaceae), based on a set of ten morphometric characters analysed by univariate and multivariate statistics. Differences between males and females in means of the selected ten characters and in several character ratios were highly significant. The multivariate analyses including principal component analysis (PCA) and canonical discriminant analysis (CDA) revealed that sex can be reliably identified in puparia in these species based on a combination of characters such as the length and width of puparia irrespective of species; length of caudal furrow for Aleyrodes sp., D. delhiensis and T. vaporariorum; length of the seventh abdominal segment for D. delhiensis and T. vaporariorum; width of operculum alone for Aleyrodes sp.; and length of vasiform orifice (LVO) alone for B. tabaci; and the combination of some of their ratios. Identification of puparium sex is important for studies in taxonomy, biology and pest management of whiteflies. The results of this study show that morphometrics can provide a useful tool for its diagnosis and accurate identification.
Stroiński Adam, Malenovský Igor, Świerczewski DariuszTwo new genera of flatid planthoppers from Socotra island (Hemiptera: Fulgoromorpha: Flatidae)Acta Entomologica Musei Nationalis Pragae 56(2): 461-489Abstract: Two new monotypic genera of flatid planthoppers (Hemiptera: Fulgoromorpha: Flatidae) are described from Socotra island (Yemen): Dixamflata gen. nov. for D. petri sp. nov. and Kesaflata gen. nov. for K. lubosi sp. nov. Habitus, male and female external and internal genital structures of the new species are illustrated and compared to similar taxa. Both new genera share an “issid-like” habitus which evolved convergently in many unrelated planthopper groups distributed in arid and semi-arid zones of the world. They might be closely related to the western Palaearctic genera Cyphopterum Melichar, 1905 and Riodeorolix Lindberg, 1956. As both new species are sub-brachypterous and were collected in plant communities specific to Socotra, they may represent endemics of the island.
Gil-Santana Hélcio R., de Oliveira JaderPratigi aristeui, a new Neotropical genus and species of Stenopodainae (Hemiptera: Heteroptera: Reduviidae)Acta Entomologica Musei Nationalis Pragae 56(2): 491-506Abstract: Pratigi aristeui gen. & sp. nov. (Hemiptera: Heteroptera: Reduviidae: Stenopodainae) is described based on a male from the state of Bahia, Brazil. Pratigi gen. nov. differs from all other New World genera by the conspicuously elongated clypeus and the subpentagonal shape of the head. Other diagnostic features of Pratigi gen. nov. include: body somewhat broad, about three times as long as maximum width, flattened dorsoventrally; postocular part of head with a ramose setigerous process posterolaterally; prosternum elongated behind fore coxae; fore femora strongly incrassate, fusiform; fore tibiae curved; all tibiae without fossula spongiosa; fore tarsi three-segmented. A revised key to New World Stenopodainae genera is presented.
Morales Irina, Forero DimitriThe genus Nabidomiris (Hemiptera: Heteroptera: Miridae): review of the species and description of a new species from South AfricaActa Entomologica Musei Nationalis Pragae 56(2): 507-516Abstract: Nabidomiris Poppius, 1914 is an African plant bug genus with three described species. Here we describe as new a fourth, Nabidomiris natalensis sp. nov. from KwaZulu-Natal (South Africa), and compare it to the other known species. Because male genitalia are important for species delimitation, and it has never been documented for any of the species of Nabidomiris, we describe for the first time the male genitalia of N. clypealis Poppius, 1914, N. longipennis Odhiambo, 1958, and N. giloicus Linnavuori, 1975. We provide a key to separate all species, and new country records for the previously described species. Nabidomiris clypealis is recorded for the first time from the Democratic Republic of the Congo and South Africa, N. giloicus from Cameroon, and N. longipennis from Tanzania.
Kment Petr, Hemala Vladimír, Baňař PetrRhyparoclava pyrrhocoroides, a new genus and species of autapomorphic Rhyparochromidae with clavate antennae from Madagascar (Hemiptera: Heteroptera)Acta Entomologica Musei Nationalis Pragae 56(2): 517-545Abstract: A new genus and species, Rhyparoclava pyrrhocoroides gen. & sp. nov. from the Montagne de Français in northern Madagascar is described and illustrated, including structures of the external scent efferent system of the metathoracic scent glands, pregenital abdomen and its trichobothrial pattern, and the genitalia of both sexes. This autapomorphic taxon is brachypterous, anocellate, and has the most strongly clavate antennae known in Rhyparochromidae (Hemiptera: Heteroptera: Lygaeoidea). The systematic placement of Rhyparoclava pyrrhocoroides is discussed and the taxon is placed in the subfamily Rhyparochrominae, and tentatively in the tribe Rhyparochromini, though examination of a larva is needed to confirm the tribal placement in the future. All known specimens of Rhyparoclava pyrrhocoroides were collected by sifting of leaf litter and other plant residues in woody parts of the Montagne de Français Reserve, characterized by strictly seasonal, dry deciduous forest. A preliminary check-list of the Rhyparochromidae of Madagascar is compiled based on literature, including 32 genera and 62 species (57 described, 5 so far undescribed) belonging to 9 different tribes, of which two genera and 41 species (i.e. 66%) are endemic to Madagascar (including its off-shore islands).
Brailovsky Harry, Barrera ErnestoNew taxa of Neotropical Acanthocerini (Hemiptera: Heteroptera: Coreidae)Acta Entomologica Musei Nationalis Pragae 56(2): 547-555Abstract: Guilbertocoris guianensis gen. & sp. nov from French Guyana, Moronopelios flavoantennatus sp. nov. from Ecuador, and Moronopelios nigritus sp. nov. from Brazil (Amazonas) and Peru are described and included in the tribe Acanthocerini (Coreidae: Coreinae). The relationships of these two genera are discussed. A detailed redescription of Moronopelios Brailovsky, 1988 and a key to identify its four known species are included. Photographs and drawings of the male genital capsule and parameres are added.
Bianchi Filipe M., Barcello Aline, Grazia JoceliaRediscovering Anhanga: redescription and considerations on its taxonomic placement (Hemiptera: Heteroptera: Pentatomidae)Acta Entomologica Musei Nationalis Pragae 56(2): 557-566Abstract: The genus Anhanga Distant, 1887 is a monotypical taxon erected for A. modesta Distant, 1887. Access to the photographs of the type specimen allowed us to identify three females and one male belonging to this genus. Here we redescribe the genus and the species and provide a detailed description of the genitalia of both sexes. Considering Distant’s original description and based on the morphological characters of Anhanga, we also re-evaluate the placement of this genus within the Discocephalinae, transferring Anhanga to the Pentatominae. Based on the general and genital morphology, Anhanga seems to have affinities with Galedanta Amyot & Serville, 1843 (tribe Carpocorini).
Kudrna ArnoštRevision of the genus Caledonica (Coleoptera: Cicindelidae)Acta Entomologica Musei Nationalis Pragae 56(2): 567-628Abstract: A revision of the endemic New Caledonian tiger beetle genus Caledonica Chaudoir, 1860 is presented based on the examination of more than 600 specimens including the relevant type material. Neotype is designated for Distipsidera mediolineata Lucas, 1862 and Distipsidera Mniszechii Thomson, 1856 as the original type material is lost. Oxycheila arrogans Montrouzier, 1860 is recognized as an unavailable name because it was proposed in synonymy and is replaced by Caledonica tuberculata Fauvel, 1882, stat. restit. The following new synonymy is proposed: Oxycheila affinis Montrouzier, 1860 = Caledonica affinis var. lerati Fleutiaux, 1911, syn. nov. Caledonica luiggiorum sp. nov. and C. rivalieriana sp. nov. are described as new to science. Males of two species, C. longicollis Fauvel, 1903 and C. rubicondosa Deuve, 2006, are described for the first time. Redescriptions of all species are given. A dichotomous key to species and subspecies is provided, and a brief history of the taxonomy and nomenclature of this genus is also given. Biology and distribution of most species and behaviour of adults in their biotopes, based on the authorʼs own field research and observations during his three surveys in New Caledonia are presented. Each species is described in detail; its habitus and diagnostic characters are illustrated in colour photographs.
Gustafson Grey T., Hájek Jiří, Miller Kelly B.Description of two new species of Dineutus sensu stricto from Southeast Asia (Coleoptera: Gyrinidae) with a key to the known species of the subgenusActa Entomologica Musei Nationalis Pragae 56(2): 629-643Abstract: Two new species of Dineutus Macleay, 1825 (Coleoptera: Gyrinidae) are described and illustrated: Dineutus barong sp. nov. from Bali, Indonesia and Dineutus sitesi sp. nov. from Thailand. A checklist to the species of the Dineutus s. str. is provided, as is a key to the species currently recognized in the subgenus together with illustrations of habitus, elytral apices and aedeagi of the species. Dineutus lethicus Guignot, 1957 syn. nov. is removed from Dineutus s. str. and it is synonymized with Dineutus (Protodineutus) indus olivaceus Régimbart, 1882.
Fery Hans, Hájek JiříNomenclatural notes on some Palaearctic Gyrinidae (Coleoptera)Acta Entomologica Musei Nationalis Pragae 56(2): 645-663Abstract: Several names of Gyrinidae taxa have been found in the literature which are given with incorrect publishing dates. The correct data could be assigned to these taxa by specifying the true publishing dates mainly of five important works: Aubé’s ‘Species général’ is dated September 29, 1838, and the third part of his ‘Iconographie’ December 31, 1838; Hatch’s ‘Phylogeny of Gyrinidae’ is dated 1926 instead of 1925; Modeer’s work on Gyrinidae is dated 1780 instead of 1776; Ochs’ works on Dineutini are dated again 1926 instead of 1927. Incorrectly cited publishing data of a few further works are also rectified. Nomenclatural notes on several names in the family Gyrinidae are provided. These are on generic level Potamobius Stephens, 1829b, and Potamobius Hope, 1838, which are both junior subjective synonyms of Orectochilus Dejean, 1833 as well as junior primary homonyms of Potamobius Samouelle, 1819 (Decapoda), and thus they are permanently invalid. Five specific names were found to be junior primary homonyms. One of them, Gyrinus orientalis Régimbart, 1883 is replaced by Gyrinus mauricei nom. nov. Three names are not only junior homonyms, but also junior subjective synonyms, and thus no replacement name is currently needed: Gyrinus striatus Olivier, 1795, Gyrinus urinator Drapiez, 1819, and Gyrinus lineatus Lacordaire, 1835. Gyrinus oblongus Boisduval, 1835 is another junior primary homonym, but this name is conserved by application of Articles 23.9.1 and 23.9.2 of the ICZN (1999). The lectotype of Dytiscus natator Linnaeus, 1758 (currently in Gyrinus Geoffroy, 1762) is designated as the neotype of Gyrinus pygolampis Modeer, 1780 for stabilising the nomenclature; Gyrinus pygolampis thus becomes a junior objective synonym of G. natator. Miscellaneous notes are provided on Gyrinus brinki Ali & Jasim, 1989, G. curtus Régimbart, 1883, G. strigosus Ghiliani, 1887, G. thurtharus Ali & Jasim, 1989, G. violaaquatica Modeer, 1780, G. viridimaculatus Atkinson 1891, and Orectochilus villosus seidlitzi Jacobson, 1908. Additionally, some infrasubspecific names are shortly dealt with.
Shavrin Alexey V., Smetana AlešA new species of the genus Acrolocha (Coleoptera: Staphylinidae: Omaliinae) from Yunnan Province, ChinaActa Entomologica Musei Nationalis Pragae 56(2): 665-670Abstract: Acrolocha zhongdianensis sp. nov. is described from China, Yunnan and illustrated. The key to Acrolocha Thomson, 1858 species of the eastern Palaearctic Region is presented.
Frank David, Sekerka LukášRevision of the subgenus Gelaeus of Chrysodema (Coleoptera: Buprestidae: Chrysochroinae)Acta Entomologica Musei Nationalis Pragae 56(2): 671-719Abstract: The subgenus Gelaeus Waterhouse, 1905 of Chrysodema Laporte & Gory, 1835 is revised based on comparative study of extensive material including types of all described taxa. The subgenus is restricted to the Lesser Sunda Islands and Selayar Islands, Indonesia. Three new species and six subspecies are described: Chrysodema (Gelaeus) katka sp. nov. from Timor Island, C. (G.) oborili oborili sp. nov. from Yamdena Islands, C. (G.) oborili laratensis subsp. nov. from Larat Island, C. (G.) sara sp. nov. from Babar Island, C. (G.) walkeri bilyi subsp. nov. from Selaru Island, C. (G.) walkeri horaki subsp. nov. from Leti Island, C. (G.) walkeri kubani subsp. nov. from Romang Island, C. (G.) walkeri nigriventris subsp. nov. from Moa Island, and C. (G.) walkeri rejzeki subsp. nov. from Alor Island. Chrysodema (G.) wetteriana (Théry, 1935) stat. nov. is raised to species rank (formely subspecies of C. (G.) walkeri (Waterhouse, 1892)). Chrysodema moluensis Novak, 2010 is assigned to Gelaeus and downgraded to subspecies C. (G.) iris moluensis Novak, 2010, stat. nov. Chrysodema (G.) cupriventris (Kerremans, 1898), stat. restit. is removed from synonymy of C. (G.) walkeri. Chrysodema (G.) florensis Lansberge, 1880, assign. nov. and C. (G.) cyanicollis Kerremans, 1900, assign. nov. are transferred from the nominotypical subgenus to Gelaeus. Lectotypes are designated for following taxa to ensure their correct application and recognition in future: Chrysodema (G.) florensis Lansberge, 1880, C. (G.) foraminifera Lansberge, 1879, C. (G.) iris (Kerremans, 1898), C. (G.) walkeri (Waterhouse, 1892), and C. (G.) wetteriana (Théry, 1935). All herein included taxa are illustrated with colour habitus photographs as is the male aedeagus when available. A key to all taxa is given.
do Nascimento Elynton A., Bocakova MiladaA new species of neotenic Neolyrium from Peru (Coleoptera: Lycidae)Acta Entomologica Musei Nationalis Pragae 56(2): 721-724Abstract: Neolyrium iquitosense sp. nov., a new species of Lycidae, is described and illustrated. This second species of the genus represents the first record of Neolyrium from Peru, keeping its distribution restricted to tropical areas of South America.
Murakami HiroyukiReview of the genera Diplopherusa and Paracladiscus (Coleoptera: Cleridae: Tillinae) from Japan and Taiwan, with descriptions of two new speciesActa Entomologica Musei Nationalis Pragae 56(2): 725-741Abstract: The genera Diplopherusa Heller, 1922 and Paracladiscus Miyatake, 1965 from Japan and Taiwan are reviewed. Two species, Diplopherusa yonaguniensis sp. nov. from Japan and Paracladiscus choui sp. nov. from Taiwan, are described as new, and in total six species of both genera occur in the studied area. A key to the species of these genera and a distributional map for Japan and Taiwan are provided.
Flinte Vivian, Viana Jéssica H., Macedo Margarete V., Windsor Donald, Sekerka LukášRevalidation and redescription of three distinct species synonymized as Plagiometriona sahlbergi (Coleoptera: Chrysomelidae: Cassidinae)Acta Entomologica Musei Nationalis Pragae 56(2): 743-754Abstract: Plagiometriona sahlbergi (Boheman, 1855), P. multisignata (Boheman, 1855) and P. scenica (Boheman, 1855) were described over a century and half ago as separate species based on dry museum specimens. The latter two were later synonymized with P. sahlbergi. While observations in nature find both P. sahlbergi and P. multisignata co-occurring on the same host plant, subtle morphological differences suggested they may be distinct species. We tested the validity of the original species separation using additional morphological characters and available molecular sequence data. The new evidence supports Boheman’s original separation of species. Accordingly we remove P. multisignata stat. restit. and P. scenica stat. restit. from synonymy with P. sahlbergi and restore their species status. Mitochondrial gene sequence data suggest that P. sahlbergi and P. multisignata bear a closer relationship to other sympatric Plagiometriona species than they do to one another, raising the possibility that these two species have convergent morphologies due to their shared food plant. Biological and ecological notes are also given for these two sympatric species.
Cho Hee-Wook, Borowiec LechRevision of the Gonioctena flavoplagiata species-group (Coleoptera: Chrysomelidae: Chrysomelinae), with descriptions of two new species from China and LaosActa Entomologica Musei Nationalis Pragae 56(2): 755-768Abstract: The Gonioctena flavoplagiata species-group of the subgenus Asiphytodecta Chen, 1935 is defined and reviewed. Two new species are described and illustrated: G. (A.) jindrai sp. nov. (southwestern China) and G. (A.) truncaticornis sp. nov. (northeastern Laos). Gonioctena (A.) eburoides (Achard, 1924) stat. restit. is resurrected from synonymy with G. (A.) flavoplagiata (Jacoby, 1890). Lectotype is designated for G. (A.) flavoplagiata. A key to the species, diagnostic characters and illustrations are provided. Ovoviviparity is newly recorded in G. (A.) flavoplagiata and G. (A.) jindrai sp. nov.
Bezděk JanIdentity of taxa proposed in Clythra (Coleoptera: Chrysomelidae: Cryptocephalinae) by Carl Peter Forsberg (1821)Acta Entomologica Musei Nationalis Pragae 56(2): 769-784Abstract: The taxa of Clythra Fabricius, 1798 (nowadays Clytra Laicharting, 1781) introduced by Carl Peter Forsberg (1821a) are reviewed. The primary type specimens of all species were examined. Mastostethus ruficauda (Forsberg, 1821), comb. nov. is transferred as a valid species to Megalopodidae. The following new synonymies are proposed: Clytra duodecimmaculata duodecimmaculata (Fabricius, 1781) = Clythra gigas Forsberg, 1821, syn. nov.; Coptocephala plagiocephala (Fabricius, 1792) = Clythra bipunctata Forsberg, 1821, syn. nov.; Tituboea biguttata (Olivier, 1791) = Clythra sexpunctata Forsberg, 1821, syn. nov.; Tituboea macropus (Illiger, 1800) = Clythra coalita Forsberg, 1821, syn. nov.; Tituboea octopunctata (Fabricius, 1787) = Clythra quadrisignata Forsberg, 1821, syn. nov. Colour photographs of all taxa described by Forsberg are also provided.
Macek JanDescriptions of larvae of the Pristiphora thalictri group of the Czech Republic (Hymenoptera: Symphyta: Tenthredinidae)Acta Entomologica Musei Nationalis Pragae 56(2): 785-794Abstract: The larva of Pristiphora sareptana Kuznetzov-Ugamskij, 1924 is described and illustrated for the first time, and the larvae of P. rufipes Serville, 1823 and P. thalictri (Kriechbaumer, 1884) are redescribed. Thalictrum foetidum and T. minus (Ranunculaceae: Thalictroideae) are the first verified host plants for P. sareptana. Pristiphora sareptana is recorded for Bohemia for the first time.
Alencar Isabel D. C. C., Colombo Wesley D., Azevedo Celso O.Pristocera masii: rediscovery of the holotype and its transfer to Acrepyris (Hymenoptera: Bethylidae)Acta Entomologica Musei Nationalis Pragae 56(2): 795-803Abstract: We report the rediscovery of the holotype of Pristocera masii Soika, 1933 (Hymenoptera: Bethylidae: Pristocerinae), originally described from a single male from Venice, Italy. The holotype was considered lost but during a scientific visit at the Museo Civico di Storia Naturale “Giacomo Doria” in Genova, Italy we were able to find the holotype. Here we provide a detailed redescription, with photographs and drawings of the main diagnostic characters delimiting this species. Pristocera masii is transferred into Acrepyris Kieffer, 1905 because its hypopygium is simple, not deeply divided as in Pristocera Klug, 1808, and its aedeagus has three distinct valvae, a remarkable and exclusive feature of Acrepyris. The resulting new combination, Acrepyris masii (Soika, 1933), is established here.
Men Qiu-Lei, Xue Guo-Xi, Yang Xue-MengTwo new species of subgenus Sivatipula from China (Diptera: Tipulidae: Tipula)Acta Entomologica Musei Nationalis Pragae 56(2): 805-811Abstract: Species of Tipula (Sivatipula) similis Men, sp. nov. from Guangxi Zhuang Autonomous Region and T. (S.) tongbiguanensis Men, sp. nov. from Yunnan Province are described and illustrated and placed in the subgenus Sivatipula Alexander, 1964. Tipula (S.) tongbiguanensis Men, sp. nov. represents the first record of Sivatipula from Yunnan Province, China.
Ježek Jan, Le Pont FrançoisPsychodidae (Diptera) of New Caledonia: checklist and description of a new genus and speciesActa Entomologica Musei Nationalis Pragae 56(2): 813-826Abstract: An account of the Psychodidae from New Caledonia is given, including the description of Cookiellocapsa caledoniensis gen. & sp. nov. based on male specimens. This new genus of uncertain tribal placement is compared with the genera Feuerborniella Vaillant, 1974 (type species Psychoda obscura Tonnoir, 1919), Threticus Eaton, 1904 (type species Pericoma lucifuga Walker, 1856) and Nielseniella Vaillant, 1972 (type species Trichopsychoda maderensis Satchell, 1955). Important diagnostic and additional morphological characters are illustrated and a checklist of known species of Psychodidae from New Caledonia is provided.
Kvifte Gunnar Mikalsen, Andersen TrondTwo new species of Nototelmatoscopus (Jozifekia), with records of three other species from Thailand (Diptera: Psychodidae)Acta Entomologica Musei Nationalis Pragae 56(2): 827-835Abstract: The subgenus Jozifekia Ježek, 2010 of Nototelmatoscopus Satchell, 1953 was erected on the basis of a single species, Nototelmatoscopus (Jozifekia) sasakawai Ježek, 2010 from Sabah, Malaysia (Borneo). In the present work, we describe two new species of this subgenus from the Chiang Mai Province in northern Thailand, both based on single males: Nototelmatoscopus (Jozifekia) acutistylus sp. nov. and Nototelmatoscopus (Jozifekia) laticoxa sp. nov. A key to the three known species of Nototelmatoscopus (Jozifekia) is provided. In addition, Clogmia albipunctata (Williston, 1893), Pneumia mitsuhiroi Ježek, 2004 and Neoarisemus laosensis Ježek, 2004 are recorded from Thailand for the first time.
Martínez Jesús, Martín Luís, González Marcos A.A new species of Potamophylax from Spain with a key to the Iberian species (Trichoptera: Limnephilidae)Acta Entomologica Musei Nationalis Pragae 56(2): 837-844Abstract: A new species of the genus Potamophylax Wallengren 1891, P. asturicus sp. nov., from Spain is described and figured. This new species is a microendemic of the Spanish Cantabrian Mountains and is closely related to P. albergaria Malicky, 1976, from which it differs in a combination of genitalic features, especially those concerning the shape of segment IX and the inferior appendages. Additionally, we provide a taxonomic key to facilitate the identification of the males of all Iberian species of this genus.
Šumpich Jan, Huemer PeterChrysoclista germanica sp. nov. and C. gabretica stat. nov., with an updated checklist of the genus (Lepidoptera: Elachistidae: Parametriotinae)Acta Entomologica Musei Nationalis Pragae 56(2): 845-854Abstract: Chrysoclista germanica sp. nov. is described from Germany (Thuringia, Bad Blankenburg). Chrysoclista gabretica Šumpich, 2012 stat. nov., originally described as subspecies of C. abchasica Sinev, 1986, is elevated to species level. Both taxonomic acts are based on the study of morphological characters of the adults (males). Photographs of voucher specimens including genitalia structures are given.
