Papáček Miroslav, Schaefer Carl W., Kment PetrWe are celebrating the seventy-fifth anniversary of Professor Pavel Štys’ birthActa Entomologica Musei Nationalis Pragae 48(2): 209-216Zrzavý JanFour chapters about the monophyly of insect ‘orders’: A review of recent phylogenetic contributionsActa Entomologica Musei Nationalis Pragae 48(2): 217-232Abstract: Recent phylogenetic analyses, both morphological and molecular, strongly support the monophyly of most insect ‘orders’. On the contrary, the Blattaria, Psocoptera, and Mecoptera are definitely paraphyletic (with respect of the Isoptera, Phthiraptera, and Siphonaptera, respectively), and the Phthiraptera are possibly diphyletic. Small relictual subclades that are closely related to the Isoptera, Phthiraptera, and Siphonaptera were identified (Cryptocercidae, Lipo- scelididae, and Boreidae, respectively), which provides an enormous amount of evidence about the origin and early evolution of the highly apomorphic eusocial or parasitic ex-groups. Position of the enigmatic ‘zygentoman’ Tricholepidion Wygodzinsky, 1961, remains uncertain. Possible non-monophyly of the Megalo- ptera (with respect of the Raphidioptera) and the Phasmatodea (with respect of the Embioptera) are shortly discussed.

Damgaard JakobEvolution of the semi-aquatic bugs (Hemiptera: Heteroptera: Gerromorpha) with a re-interpretation of the fossil recordActa Entomologica Musei Nationalis Pragae 48(2): 251-268Abstract: The fossil history of semi-aquatic bugs (Gerromorpha) is reviewed in light of the many important recent records and new developments in our under- standing of the phylogeny of the group. Based on the age of its sister group, the Panheteroptera, the Gerromorpha probably extends back into the Triassic, even though the oldest fossil forms assigned to the group are dubious. The recent dis- covery of Cretogerris albianus Perrichot, Nel & Neraudeau, 2005 from the Lower Cretaceous shows that all families were present in the Mesozoic, and phylogenetic and biogeographic evidence suggest that most – perhaps all – extant subfamilies were also present at that time. By comparison, the fossil record of the families Hydrometridae and Gerridae is far richer than that of any other family, which allows a more detailed interpretation of the phylogenetic relationships among extinct and extant taxa of these two groups.
Chen Ping-ping, Nieser Nico, Lansbury IvorNotes on aquatic and semiaquatic bugs (Hemiptera: Heteroptera: Nepomorpha, Gerromorpha) from Malesia with description of three new speciesActa Entomologica Musei Nationalis Pragae 48(2): 269-279Abstract: Micronecta lumutensis sp. nov. (Micronectidae) from Kalimantan (Borneo, Indonesia), Enithares rinjani sp. nov. (Notonectidae) from Lombok (Indonesia) and Neusterensifer stysi sp. nov. (Veliidae) from New Guinea are newly described. In addition, distributional records are given for three species of the genus Enithares Spinola, 1937, Neusterensifer sepik (Polhemus & Polhemus, 1994), and Tenagogonus kampaspe (Kirkaldy, 1900). Morphological variability in T. kampaspe is discussed.
Polhemus Dan A., Polhemus John T.A new Indian Ocean species of Ochterus from the island of Mauritius (Hemiptera: Heteroptera: Ochteridae)Acta Entomologica Musei Nationalis Pragae 48(2): 281-288Abstract: Ochterus stysi sp. nov. is described from the island of Mauritius in the western Indian Ocean. This species is only the second member of the family Ochteridae known from the islands of the Indian Ocean east of Madagascar, and the first recorded from the Mascarene Archipelago. Comparative notes are pro- vided in regard to this new species and Ochterus seychellensis Polhemus, 1992, its closest putative relative. Figures are provided of the dorsal habitus and male genitalic structures.
Polhemus John T., Polhemus Dan A.Intraspecific morphological polymorphism in Naucoridae (Hemiptera: Heteroptera) with notes on nomenclature and synonymyActa Entomologica Musei Nationalis Pragae 48(2): 289-298Abstract: Trends in intraspecific variation among certain aspects of pronotal and tarsal morphology within the family Naucoridae are reviewed, and linked to previously flawed taxonomic decisions regarding species separation or generic assignments within this group, particularly in the subfamily Laccocorinae. In par- ticular, we review evidence that the shape of the posterolateral pronotal angles is linked to differing degrees of fore- and hindwing development across the family as a whole, and that members of the subfamily Laccocorinae exhibit intersexual variation in both fore tarsal segmentation and the number of claws on the foreleg. Misinterpretation of such character state variation has been utilized as an invalid basis for separation of putatively distinct species by many authors over the past 50 years. Based on this analysis, we propose the following taxonomic changes (valid names listed first): Laccocoris staudingeri Montandon, 1897 = Laccocoris maai La Rivers, 1970, syn. nov. = Laccocoris lipogonia La Rivers, 1970, syn. nov.; Interocoris La Rivers, 1974, stat. nov. (currently subgenus of Heleocoris Stål, 1876) is raised to full generic status to contain Interocoris mexicanus (Usinger, 1935), comb. nov. (formerly held under Heleocoris (Interocoris) mexicanus Usin- ger, 1935); the following Neotropical species are transferred from Heleocoris to Ctenipocoris Montandon, 1897: Ctenipocoris brasiliensis (De Carlo, 1968), comb. nov., Ctenipocoris peruvianus (La Rivers, 1974), comb. nov., Ctenipocoris schadei (De Carlo, 1940), comb. nov., Ctenipocoris spinipes (Montandon, 1897), comb. nov.; and Heleocoris faradjensis La Rivers, 1960 is transferred to Ctenipocoris and synonymized such that Ctenipocoris africanus Poisson, 1948 = Heleocoris faradjensis La Rivers, 1960, syn. nov.
Papáček Miroslav, Soldán TomášStructure and development of the reproductive system in Aphelocheirus aestivalis (Hemiptera: Heteroptera: Nepomorpha: Aphelocheiridae)Acta Entomologica Musei Nationalis Pragae 48(2): 299-318Abstract: We study the histology, ultrastructure and morphological arrangement of male and female reproductive system of Aphelocheirus aestivalis (Fabricius, 1803) in the nymphs of instar 1-5 and variously aged apterous adults. The anlage of gonads becomes well apparent already in instar 1, testicular follicles and ovarioles start to differentiate in instar 2, and their entire differentiation is finished in instar 3. Paired accessory mesadenia, dichotomically branched in adult males, differen- tiate in instar 2 as well. The anlage of male ectodermal accessory gland is formed during instar 3, while spermatheca and bursa copulatrix start to invaginate in instar 4. Morphological differentiation of germ cell descendents as well as formation of the germarial trophic core from a membranous labyrinth in females occurs in late instar 4 and instar 5. Spermatogenesis shows a unique character within the whole Nepomorpha: it is a permanent, multi-waved process, as all developmental stages of male germ cells are found throughout the year. Vitellogenesis starts in adult females 3-4 weeks after the last moulting but apparently stops during winter. The timing of crucial reproductive processes in A. aestivalis seems to be rather different from most aquatic bugs; permanent, spring-to-autumn gradual spermatogenesis and physiological ability to copulate, and the presence of mature spermatozoa in the spermatheca of teneral, newly hatched females indicate possible semivoltinism in the life cycle. Three new apomorphies (type of spermatogenesis and secondary seminal vesicles in males, and a cuticular brush in bursa copulatrix in females) of the Aphelocheiridae are defined.

Two species are described as new to science, Orthosaldula stysi sp. nov. from Leyte and O. flavonigra sp. nov. from Cebu.
Weirauch ChristianeFrom four- to three-segmented labium in Reduviidae (Hemiptera: Heteroptera)Acta Entomologica Musei Nationalis Pragae 48(2): 331-344Abstract: The majority of Reduviidae – unlike most other Heteroptera – has a labium that consists of only three segments. The first segment is said to be either lost or fused to the head capsule. Cladistic analysis shows that this loss or fusion occurred once or twice among basal Reduviidae and that the four-segmented labium in Hammacerinae is plesiomorphic and homologous to the one in non- reduviid Cimicomorpha. In the present contribution, extrinsic labial muscles and sclerites associated with the base of the labium are documented (micro-dissecti- ons, histology) for Himacerus apterus (Fabricius, 1789) (Nabidae), Microtomus purcis (Drury, 1782) (Reduviidae: Hammacerinae) and Rhynocoris erythropus (Linnaeus, 1767) (Reduviidae: Harpactorinae). Primary homology hypotheses are proposed on lever, depressor, and transverse muscles among the examined taxa and previously published descriptions of Nepomorpha and Leptopodomorpha. The two Reduviidae are unique in having a large portion of the Musculus levator labii (muscle A) originating from the first labial segment (M. purcis) or the gena (R. erythropus). This may indicate that part of the gena is homologous to part of the first labial segment, i.e. the proximal portion of the first labial segment may be fused to the gena, but migration of the muscle origin may also account for this condition. The insertion of M. transversalis labii has shifted from the dorsal surface of the first labial segment to the anterior portion of the suspensory plate, possibly indicating that this structure may include part of the first labial segment. Even though the first labial segment is not visible externally in the majority of Reduviidae, two muscles that were originally associated with it are thus retained. Mapped on a phylogeny of Reduvioidea it seems evident that in a first step the levator muscle became larger at the base of the Reduviidae. In a second step the first labial segment fused to the head capsule, possibly providing this enlarged muscle with a more solid origin.
Ishikawa Tadashi, Susila Wayan, Okajima Shûji Two new species of the emesine assassin bug genus Ploiaria (Hemiptera: Heteroptera: Reduviidae) from IndonesiaActa Entomologica Musei Nationalis Pragae 48(2): 345-359Abstract: Two new species of the emesine reduviid genus Ploiaria Scopoli, 1786, P. stysi sp. nov. and P. paveli sp. nov., are described from Bali and Flores, Indone- sia. Ploiaria stysi sp. nov. differs from P. maai Wygodzinsky, 1966, by the male antennal segments I and II lacking long setae, the procoxa 1.3 times as long as the pronotum, the anteroventral series of the profemur beginning with two basal spine-like setae distinctly placed from other spine-like setae, the parameres not overlapping each other in rest, etc. Ploiaria paveli sp. nov. is distinguished from P. halosydne Wygodzinsky & Usinger, 1960, by the body length more than 12 mm, the anteroventral series of the profemur beginning with one basal spine-like seta distinctly placed from other spine-like setae, the metafemur pale in apical part, etc.

Remane Reinhard, Günther HannesAcetropis stysi, a new species from Spain (Hemiptera: Heteroptera: Miridae)Acta Entomologica Musei Nationalis Pragae 48(2): 389-394Abstract: Acetropis stysi sp. nov. is described from Sierra de Gredos of Ávila province in Central Spain. The new species is most similar to A. longirostris Puton, 1875, but in some respects is also similar to A. carinata (Herrich-Schaeffer, 1841). Males are macropterous, females macropterous and submacropterous. The new species is clearly distinguished from A. longirostris and A. carinata by the structure of the pygopore and from A. carinata and all other Acetropis species by the shape and partly by the numbers of vesical spiculae. It differs from the remnant species, A. gimmerthalii (Flor, 1860), A. sinuata Wagner, 1951, and A. atropis Reuter, 1895, by many characters.

Their generic placement and differences to other taxa are discussed.
Cassis Gerasimos, Symonds CeliaSystematics, biogeography and host associations of the lace bug genus Inoma (Hemiptera: Heteroptera: Tingidae)Acta Entomologica Musei Nationalis Pragae 48(2): 433-484Abstract: The lace bug genus Inoma Hacker, 1927 is revised, including a rede- scription of the genus and the type species, I. multispinosa Hacker, 1927. Eight species are described as new to science, as follows: I. arrernte sp. nov., I. breviseta sp. nov., I. fuscata sp. nov., I. innamincka sp. nov., I. kalbarri sp. nov., I. silveirae sp. nov., I. solusa sp. nov. and I. stysi sp. nov. A key to species is provided, and diagnostic characters are illustrated. Inoma angusta Drake, 1942 is not congeneric with the above species, based on the given redescription, and is posited as incertae sedis. Inoma is endemic to Australia, with a mostly arid distribution, with up to three species recorded from a single locality. Host plants of Inoma are recorded for the first time, predominantly from the angiosperm plant families, Lamiaceae and Myoporaceae, and most commonly from species of the ubiquitous genera Eremophila and Dicrastylis.

Pluot-Sigwalt DominiqueA pair of basi-abdominal sex pheromone glands in the male of some burrower bugs (Hemiptera: Heteroptera: Cydnidae)Acta Entomologica Musei Nationalis Pragae 48(2): 511-522Abstract: Paired pleural basi-abdominal glands (PBA glands) were found in males of some burrower bugs (Pentatomoidea: Cydnidae). So far, they seem to be restricted to the subfamily Cydninae, tribes Cydnini (except Cydnus aterri- mus (Forster, 1771) and Geotomini, and are absent in examined representatives of the subfamilies Amaurocorinae, Cephalocteinae, and Sehirinae. PBA glands are laterally and symmetrically situated underneath the mediotergite 3. They are simple sac-like formations covered by several hundreds of secretory units. Each gland opens to the exterior in the posterior part of the membranous pleural area of the fused first and second mediotergites, just in front of the connective line linking laterotergite and sternite 3. The slit-shaped minute ostioles are hidden by the wing in the resting insect and are located adjacent to the stridulatory structures. The secretory activity of the PBA glands is clearly correlated with sexual activity and mating period; therefore the glands might be the source of an attractant sex pheromone for the female. PBA glands are possibly functionally associated with stridulation-vibration during courtship and mating. Unlike the Sehirinae (lacking the paired PBA glands), the Cydninae exhibit an unusual copulatory position, the male being positioned underneath the female, similar to the condition found in the Aradidae and Ceratocombidae.
Gapon Dmitry A.New subtribes and a new genus of Podopini (Heteroptera: Pentatomidae: Podopinae)Acta Entomologica Musei Nationalis Pragae 48(2): 523-532Abstract: The tribe Podopini is divided into three subtribes: Kayesiina subtrib. nov., Podopina, and Scotinopharina subtrib. nov., differing in the length and sha- pe of jugae, presence or absence of a tooth on the anterior part of bucculae and transverse carinae on pronotum, structure of pygophore, parandria, aedeagus, and female genitalia. Scotinophara dentata Distant, 1902, is transferred to a new genus, Stysiellus gen. nov., which differs from Scotinopharina in having large pyramidal lateral parandria, characteristic of Podopina, and some other characters. Stysiellus gen. nov. is distributed in India and Nepal (new record).

Hájek Jiří, Fikáček MartinA review of the genus Satonius (Coleoptera: Myxophaga: Torridincolidae): taxonomic revision, larval morphology, notes on wing polymorphism, and phylogenetic implicationsActa Entomologica Musei Nationalis Pragae 48(2): 655-676Abstract: The genus Satonius Endrödy-Younga, 1997, is revised. Three new spe- cies are described from China: Satonius schoenmanni sp. nov. (Hunan province), S. stysi sp. nov. (Yunnan province), and S. wangi sp. nov. (Zhejiang province). Two additional new species from the Chinese provinces Fujian and Anhui are left undescribed pending the collection of complete specimens and males, respecti- vely. Metathoracic wing venation of S. stysi sp. nov. is shown to differ from the remaining Myxophaga in the presence of the bifurcation of AA3+4, which updates the venation groundplan of the suborder. Anterolateral spine-like projection of the metaventrite and the increased number of apical setae on parameres are defined as adult autapomorphies of the genus. Larvae of S. stysi sp. nov. are described and compared with the larvae of the Japanese S. kurosawai (Satô, 1982). Characters shared by larval Satonius and Ytu Reichardt, 1973 (extremely flattened body covering legs, and modified orientation and unusual morphology of legs) are supposed as parallel adaptations for the larval environment – very thin film of water in seepage habitats. Interspecific wing polymorphism of Satonius is briefly discussed and possible reasons of the wide distribution of the apterous S. kuro- sawai are hypothesized.
Skuhrovec Jiří Taxonomic changes within the tribe Hyperini (Coleoptera: Curculionidae)Acta Entomologica Musei Nationalis Pragae 48(2): 677-690Abstract: The taxonomic status of three genera (Donus Jekel, 1865, Brachypera Capiomont, 1868 stat. restit., and Hypera Germar, 1817) in the tribe Hyperini is clarified, including the identity of the type species of each genus, and problematic groups in each genus are commented. Neoglanis Alonso-Zarazaga & Lyal, 1999, is recognized as a junior synonym of Donus, because its type species, Phytonomus velutinus Boheman, 1842, is congeneric with Rhynchaenus philanthus Olivier, 1807, the type species of Donus. Subsequently, Brachypera is resurrected from synonymy and used to accomodate species previously assigned to Donus and not congeneric with Rhynchaenus philanthus; Phytonomus crinitus Boheman, 1834, is designated as the type species of Brachypera. Pseudhypera Capiomont, 1868, is a new junior synonym of Brachypera; Hypera reichei Capiomont, 1868, is designated as the type species of Pseudhypera. Antidonus Bedel, 1886, is trans- ferred to Brachypera and included as a subgenus. A list of species belonging to the genera Donus and Brachypera is given, including 146 new combinations. The nomenclatoric situation of Phytonomus Schoenherr, 1823, previously recognized as an unnecessary replacement name for Hypera Germar, 1817, is reviewed.
