A Revision Of Dyscolotaxia Horn, 1890 (Coleoptera: Eucnemidae: Macraulacinae: Macraulacini), With The Description Of Amazotaxia New Genus From South America, Robert L. Otto
Insecta Mundi
Abstract
The Neotropical eucnemid genus, Dyscolotaxia Horn, is revised following the examination of specimens from five collections, examination of the published original description of Plesiofornax tetratoma Chassain, and from images provided by Fernanda Salazar-Buenaño (QCAZI). Dyscolotaxia championi Horn is redescribed with included descriptions of the male genitalia and a female specimen. Three new species of false click beetles (Coleoptera: Eucnemidae) are described from the Neotropical region. These new species are: Dyscolotaxia chiriquiensis (Panama), Dyscolotaxia hispaniolensis (Dominican Republic), and Dyscolotaxia picea (Ecuador). Amazotaxia new genus is described from South America for Plesiofornax tetratoma Chassain, creating Amazotaxia tetratoma (Chassain) new combination. Morphology …

Plagiosarus transversus Vlasak and Santos-Silva, new species (Cerambycidae: Lamiinae: Acanthoderini), is described from Costa Rica. The rank of Plagiosarus melampus congestus Bates, 1885 is discussed.
Phylogenetics And Integrative Taxonomy Of African Water Snakes (Squamata: Colubridae: Grayia), Teslin Chaney
Phylogenetics And Integrative Taxonomy Of African Water Snakes (Squamata: Colubridae: Grayia), Teslin Chaney
Open Access Theses & Dissertations
Grayia is a genus of relatively large (1.5 - 2.5 m) aquatic Afrotropical snakes. Recent molecular phylogenies recovered Grayia in its own distinct subfamily (Grayiinae), which was strongly supported as the sister group to Colubrinae. Because tropical African snakes are generally understudied, the relationships within Grayia are poorly known. Due to high degrees of intra- and interspecies variation, identification is often difficult and previous studies involving Grayia included misidentified specimens in other genera. The goal of this study is to create a phylogenetic tree that can be used to understand the relationships and taxonomy of Grayia via an integrative taxonomic …
