Sternum about 1 / 3 of total length of epimerites I ( Fig. 5 View FIGURE 5 B). Epimerites I–IV without wide sclerotized areas. Sclerotized area of epimerites IIa with narrow longitudinal membrane. Epimerites IIIa extending to level of subhumeral setae c 3. Epimerites IV with triangle-shaped sclerotized area at bases of trochanters IV. Epimerites IVa absent. Genital apparatus at level of trochanters IV. Genital arch 13 in length, 31 in width at base. Aedeagus short, dagger-shaped,, 22 in length, extending slightly beyond base of arch, but does not extending to setae g. Genital papillae free, arranged in almost transverse row. Anal suckers large, cylindrical, slightly curved, with thickened corolla, 22 long, 23 in diameter at apical part, corolla with several small indentations. Adanal shields as small plates around bases of setae ps 3. Distance between ventral setae: 3 b: 3a 13, 3a: 4a 46, 4 a: g 64, g: ps 3 42, ps 3: ps 3 22, ps 3: h 3 51.

Genual setae cG I narrowly lanceolate; setae cG II, mG I, mG II thickened basally, with filiform apex ( Figs. 6 View FIGURE 6 F, G). Solenidion σ 1 of genu III approximately at midlevel of segment. Solenidion ϕ of tibia IV extending to distal margin of ambulacral disc. Tarsus IV 51 long, with short apical extension; seta d situated at level of distal third of segment, seta e on apical extension ( Fig. 6 View FIGURE 6 H).

Prodorsal shield: lateral margins without incisions, antero-lateral extensions fused with bases of epimerites Ia, posterior margin slightly concave, surface punctate, with small dash- and pit-like lacunae in posterior part, length along midline 130–137, width at posterior margin 140–145 ( Fig. 5 View FIGURE 5 A). Setae se separated by 90–95. Scapular shields wide. Setae c 1 on soft tegument or on anterior margin of hysteronotal shield. Setae c 2 on anterior margin of humeral shields. Setae c 3 lanceolate, 22–24 x 7. Distance between prodorsal and hysteronotal shields 12–15. Hysteronotal shield entire, anterior margin straight or slightly concave, total length 310–320, length from anterior margin to anterior end of terminal cleft 263–280, width at anterior margin 135–140, surface punctate, with sparse dash-like lacunae in median part.

Etymology. This species is named in honour of Tom Atyeo, one of the greatest feather mite systematists, who passed away in October 2008.
