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
).
