Bimichaeliini Womersley, 1944


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. 119View FIGURES 119−125, 133A, BView FIGURE 133) or in clumps ( Figs. 133C, DView FIGURE 133) 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).
