Phylogeny and Revision of the Anchomenus Clade The Genera Tetraleucus, Anchomenus, Sericoda, and Elliptoleus (Coleoptera: Carabidae: Platynini)

About this book

Taxa comprising the Anchomenus clade within the carabid tribe Platynini, subtribe Platyni, possess the synapomorphy of a female spermatheca with a basal reservoir and a long apical filament. As presently constituted, this clade comprises 29 species arrayed in four genera; the monotypic Tetraleucus Casey in eastern North America, the Holarctic Anchomenus Bonelli with 10 species, the Holarctic Sericoda Kirby with 7 species, and the Mexican Elliptoleus Bates with 11 species. Seven species are newly described; Anchomenus capensis, n. sp. from Baja California Sur, Sericoda montana, n. sp. from Cuba, Elliptoleus corvus, n. sp. from México state, Elliptoleus zapotecorum, n. sp. from Oaxaca, Elliptoleus whiteheadi, n. sp. from Guerrero, Elliptoleus balli, n. sp. from Jalisco and Michoacan, and Elliptoleus tequilae, n. sp. from Jalisco. New combinations proposed include: Tetraleucus picticornis Newman (removed from Agonum Bonelli); Anchomenus virescens Motschulsky (removed from Chlaeniomimus Semenow, 1889, as that generic name is a new synonym of Anchomenus Bonelli, 1810); Anchomenus yukihikoi (removed from Agonum (Nipponanchus) Habu, 1978, as that subgeneric name is a new synonym of Anchomenus); Sericoda ceylonica (removed from Agonum Bonelli), and Sericoda lissoptera (removed from Anchomenus Bonelli).
