Bimichaeliini Womersley, 1944 Type genus: Bimichaelia Thor, 1902. Differential diagnosis. The lineage and tribe can be separated from its sister group by having the large lamellae either in cells (Figs. 119, 133A, B) or in clumps (Figs. 133C, D) on soft integument, having lost their eyes and cheliceral setae, and femora IV are not divided. Otherwise, they share all the typical bimichaeliine character states, such as presence of a button-like naso, clavate sensilla sci, stylet-like chelicerae, and an apical palpal solenidion in contact with TP-type eupathid(s). Remark. The tribe Bimichaeliini is a sister group of the monotypic tribe Proteromichaeliini established above and includes all the other genera of the subfamily Bimichaeliinae. The generic name Bimichaelia Thor, 1902 was proposed as a nomen novum for Michaelia Berlese, 1884 (preoccupied, non Michaelia Trouessart, 1884), see Uusitalo (2010: 64).
