Etymology: The specific name comes from a Latin word, comosus, meaning “with long hairs”, referring to the medially long hairs on dorsal surface of carapace.
Diagnosis: The new species can be easily distinguished from all the other congeners by the shape of booklung covers, which is rectangular, and strongly chitinized at anterolateral edge (Figs 2B, C), by the smooth sternum (Fig. 1C), and by the carapace anterior strongly narrowed (Figs 1A, 3A) and with medially long hairs on dorsal surface.
Description: Male. Body yellowish brown, chelicerae and sternum lighter, legs yellow. Body length 2.42–2.71; carapace 1.14–1.17 length, 0.91–0.97 width; abdomen 1.48–1.66 length, 1.03–1.14 width. Clypeus with a row of finely hairs at anterior margin; clypeus height about 0.3 times the diameter of anterior eyes. Pars cephalica slightly elevated in profile (Fig. 1B). Carapace smooth all over, anterior strongly narrowed (Figs 1A, 3A), with a row of finely hairs along margin; its dorsal surface with two rows of short, finely hairs laterally and several directed long hairs medially, the long hairs about 5–6 times as long as the short lateral hairs (Fig. 3B). Eyes six, ALE slightly larger, PLE smallest, ALE separated by less than its radius; posterior eye row nearly straight in dorsal view. Labium with 2 setae at anterior margin. Sternum smooth, with narrow, transverse palpal groove, covered with thin hairs standing in small pits; without radial furrows (Fig. 1C). Measurements of legs: I 3.07 (0.91, 0.43, 0.68, 0.63, 0.42); II 3.07 (0.91, 0.43, 0.68, 0.63, 0.42); III 2.65 (0.80, 0.37, 0.54, 0.60, 0.34); IV 3.53 (1.06, 0.48, 0.74, 0.83, 0.42). Leg formula: IV–I–II–III. Dorsal scutum ovoid, punctate, densely covered with short hairs. Booklung covers nearly rectangular, anterolateral edge with well developed tubercle. Pedicel tube short, without dorsolateral extension, scuto-pedicel region unmodified (Figs 2B, C). Sperm pore small, slit-like. Colulus represented only by two setae. Cymbium and bulbus of palp yellowish white, the other segments yellow. Bulbus longer than cymbium, apex conical, acute tipped. Embolus-conductor complex, mesially bent in dorsal view (Figs 3C, D).
Female. Similar to male in coloration and general features, but body size larger, sternum without palpal groove. Body length 2.79–3.27; carapace 1.14–1.31 length, 0.96–1.10 width; abdomen 1.75–1.93 length, 1.37–1.45 width. Measurements of legs: I 3.40 (1.03, 0.48, 0.79, 0.69, 0.41); II 3.40 (1.03, 0.48, 0.79, 0.69, 0.41); III 3.16 (0.96, 0.45, 0.65, 0.69, 0.41); IV 3.93 (1.14, 0.52, 0.89, 0.93, 0.45). Epigastric area without any external specialities (Fig. 2A). Vulva with a large receptaculum and complicated sclerites (Fig. 3E).
