Taxonomic revision of the sub-Saharan Anthidiellum Cockerell (Apoidea: Megachilidae: Anthidiini) Author Eardley, Connal text Zootaxa 2018 2018-03-28 4402 2 201 250 journal article 30401 10.11646/zootaxa.4402.2.1 3270409d-d789-45b8-be3a-cae44026650c 1175-5326 1208804 16374B7F-CC86-4799-8600-DCDCADD06E8E Anthidiellum Cockerell Dianthidium ( Anthidiellum) COcKERELL 1904: 3. TyPE SPEcIES: Trachusa strigata PANZER, By ORIgINAL DESIgNAtION. Anthidiellum COcKERELL : ARMBUStER AND StEINER 1992: 310–312. In all Anthidiellum the distal end of the mandibles, when closed, are more or less parallel with the long axis of the face, and Afrotropical species have three to four teeth. The subantennal suture is bowed outwards and the scutoscutellar suture is open and shiny. In males, the distal margin of the sixth tergum is suppressed and translucent. Pycnanthidium females have a unique wide hind basitarsus. In both sexes, the preoccipital carina is confined to the area behind the vertex. In Chloranthidiellum , it continues laterally to the malar area. The males can be separated by the sterna. In females, however, colour seems to be the only separating character, and it is unreliable.
