The assassin bug subfamilies Centrocnemidinae and Holoptilinae in Taiwan (Hemiptera: Heteroptera: Reduviidae)

Abstract: The assassin bugs (Hemiptera: Heteroptera: Reduviidae) of the subfamily Centrocnemidinae and Holoptilinae of Taiwan are surveyed, the taxa are diagnosed, illustrated, and keyed. The nomenclature of the family group name Centrocnemidinae is discussed. Of this subfamily, the single species Neocentrocnemis stali (Reuter, 1881) is recognized, old records of Centrocnemis deyrollii Signoret, 1852 are considered as misidentifications of N. stali. The following synonymies are proposed: Neocentrocnemis stali (Reuter, 1881) = N. formosana (Matsumura, 1913), syn. nov., = N. baudoni Dispons, 1965, syn. nov. The male and female genitalia of N. stali are illustrated in detail, the morphology and homologies of the male intromittent organ are discussed. Of Holoptilinae, two genera and three species are recognized. The genus Locoptiris Villiers, 1943, described from the Afrotropical Region, is recorded for the first time from Taiwan; this record means also the first record of the genus in the Oriental Region. Locoptiris taiwanensis sp. nov. is described as new. Ptilocerus pendleburyi Miller, 1940, described from peninsular Malaysia, is transferred to Locoptiris. Species of Locoptiris are keyed, the relationships within the genus are discussed. Ptilocerus immitis Uhler, 1896, so far known only from Japan, is recorded for the first time from Taiwan.
