Taxonomic synopsis of the subtribe Physoderina (Coleoptera, Carabidae, Lebiini), with species revisions of eight genera

Abstract

Ten genera of Physoderina from the Oriental Region are diagnosed and described, and twenty six species representing eight genera (Paraphaea Bates, Anchista Nietner, Metallanchista gen. n., Diamella nom. n., Allocota Motschulsky, Orionella Jedlička, Endynomena Chaudoir and Dasiosoma Britton (Oriental species only)) are revised. Keys to genera and species are provided, along with distribution maps, habitus images, photographs of the name-bearing types, and illustrations of male and female genitalia of available species. The female internal reproductive system is illustrated for fourteen species. Two genera, Anchista and Taicona, previously placed in Calleidina, are moved into Physoderina. One new genus is described: Metallanchista, gen. n. (type species M. laticollis, sp. n.). Two new generic synonyms are proposed: Taicona Bates, 1873, junior synonym of Allocota Motschulsky, 1859; Teradaia Habu, 1979a, junior synonym of Dasiosoma Britton, 1937. A new generic replacement name is proposed: Diamella, nom. n. for Dianella Jedlička, 1952 (junior homonym of Dianella Gude, 1913). The status of Paraphaea Bates, 1873 is resurrected from synonym of Anchista Nietner, 1856. Five new species are described: Paraphaea minor Shi & Liang, sp. n. (Hoa-Binh, Tonkin, Vietnam), Anchista pilosa Shi & Liang, sp. n. (Chikkangalur, Bangalore, India), Metallanchista laticollis Shi & Liang, sp. n. (PhaTo env., Chumphon prov., Thailand), Allocota bicolor Shi & Liang, sp. n. (Dengga to Mafengshan, Ruili, Yunnan, China), Dasiosoma quadraticolle Shi & Liang, sp. n. (Menglun Botanical Garden, Yunnan, China). Fourteen new combinations are proposed: Paraphaea binotata (Dejean, 1825), comb. n. from Anchista; Paraphaea formosana (Jedlička, 1946), comb. n. from Anchista; Paraphaea philippinensis (Jedlička, 1935b), comb. n. from Allocota; Metallanchista perlaeta (Kirschenhofer, 1994), comb. n. from Allocota; Physodera andrewesi (Jedlička, 1934), comb. n. from Allocota; Diamella cupreomicans (Oberthür, 1883), comb. n. from Physodera; Diamella arrowi (Jedlička, 1935a), comb. n. from Allocota; Allocota aurata (Bates, 1873), comb. n. from Taicona; Dasiosoma bellum (Habu, 1979a), comb. n. from Teradaia; Dasiosoma indicum (Kirschenhofer, 2011), comb. n. from Dianella; Dasiosoma maindroni (Tian & Deuve, 2001), comb. n. from Lachnoderma; Dasiosoma hirsutum (Bates, 1873), comb. n. from Lachnoderma; Orionella discoidalis (Bates, 1892), comb. n. from Anchista; Orionella kathmanduensis (Kirschenhofer, 1994), comb. n. from Lachnoderma. Five names are newly placed as junior synonyms: Paraphaea eurydera (Chaudoir, 1877), junior synonym of Paraphaea binotata (Dejean, 1825); Anchista glabra Chaudoir, 1877, and Anchista nepalensis Kirschenhofer, 1994, junior synonyms of Anchista fenestrata (Schmidt-Göbel, 1846); Allocota caerulea Andrewes, 1933, junior synonym of Allocota viridipennis Motschulsky, 1859; Allocota perroti (Jedlička, 1963), junior synonym of Allocota aurata (Bates, 1873). One new replacement name is proposed: Dasiosoma basilewskyi, nom. n. for Dasiosoma hirsutum Basilewsky, 1949 (secondary junior homonym of Dasiosoma hirsutum (Bates, 1892)). One species is downgraded to subspecies rank: Anchista fenestrata subpubescens Chaudoir, 1877, new rank.
