trib. nov.

Proteromichaeliini  trib. nov.

Type genus: Proteromichaelia  gen. nov.

Differential diagnosis. The sole member of this new tribe has several plesiomorphic character states distinctly different from other members of the subfamily Bimichaeliinae  . The new tribe can easily be differentiated from its sister group by having large lamellae (the primary cuticular pattern) organized both in cells and in clumps inside the cells ( Figs. 92View FIGURES 90−100, 134A, BView FIGURE 134), secondary pattern by glabrous ridges (small granules/lamellae absent, Figs. 92View FIGURES 90−100, 134BView FIGURE 134), a pair of eyes present ( Figs. 90, 91View FIGURES 90−100, 104View FIGURES 101−104), a pair of cheliceral setae present ( Fig. 94View FIGURES 90−100) and divided femora IV ( Fig. 101View FIGURES 101−104; Uusitalo 2010: Appendix 3). In other respects, the species is the same as the rest of the bimichaeliines.

Description. Hysterosoma soft, segmented ( Fig. 91View FIGURES 90−100); ornamented idiosomal cuticle ( Figs. 92View FIGURES 90−100, 134A, BView FIGURE 134): primary pattern formed by large lamellae of polygons and separate clumps, secondary pattern by fine ridges ( Figs. 92View FIGURES 90−100, 134A, BView FIGURE 134); adults neotrichous, dorsal and ventral setae ciliated, genital, anal and pedal setae elongated, plumose ( Figs. 92, 93, 97, 98View FIGURES 90−100, 134BView FIGURE 134); prodorsum ( Figs. 90, 91View FIGURES 90−100, 134AView FIGURE 134): naso button-like, a pair of lateral eyes present; posterior sensilla sci globular, barbed, anterior pair of sensilla ve filamentous; chelate chelicera elongated into stylet-like elements, a pair of cheliceral setae present ( Fig. 94View FIGURES 90−100); subcapitulum elongated, rutella missing, adoral setae missing ( Fig. 95View FIGURES 90−100); palpi with an apical solenidion and two eupathids ( Fig. 96View FIGURES 90−100); supracoxal setae ep present, supracoxal setae eI present, femora IV divided, eupathids apically and ventrally on tarsi I and II, solenidia baculiform and ceratiform, symmetrically paired claws with fine barbs, setulate empodia clawless ( Figs. 98–100View FIGURES 90−100).

Remark. This monotypic sister group of Bimichaeliini  was obtained from the analysis of the family Alycidae  . Some drawings of the undescribed species ‘ sil ’, representing the new tribe, were included already in the analysis paper to illustrate the character state differences ( Uusitalo 2010: Appendix 3).
