Scales: A, B, D, E = 0.1 mm; C = 0.05 mm.
Etymology.
The specific name is Latin, meaning spot, referring to the dark spot in the middle of anterior scutal ridge of female genital area; noun.
Diagnosis.
The new species is similar to
O. media
Song & Xu, 1984
, but can be distinguished by the smooth posterior margin of the postgynum depression of females, bow-like in
O. medius
(compare
Fig. 7
D and
Song & Xu 1984
:
Fig. 4
) and by the different shape of distal part of male palpal bulb (compare
Fig. 7
A and
Song & Xu 1984
:
Fig. 5
).
Description.
Male (
holotype
). Yellowish brown species with yellow legs. Body length 1.53; carapace 0.67 long, 0.52 wide; abdomen 0.87 long, 0.62 wide. Habitus as in
Fig. 5
A, B. Carapace: elongated oval in dorsal view, sides with longitudinal streaks; dorsal area smooth with some hairs at lateral edges;
pars cephalica
slightly elevated in lateral view (
Fig. 5
E); lateral margin rebordered. Eyes: six, well developed, ALE largest, PLE smallest; posterior eye row straight from above, procurved from front; ALE separated by less than their radius, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius. Clypeus margin unmodified; clypeus height about 1.2 times ALE diameter (
Fig. 5
F). Sternum longer than wide, uniform, fused to carapace; radial furrows present between coxae I-II, II-III, III-IV, with rows of small pits; surface smooth, without pits, microsculpture only in furrows. Anterior end of endites with a small, sharply pointed projection (
Fig. 5
D, E). Legs short, thick and spineless. Abdomen: dorsal scutum strongly sclerotized, punctate, covering full length of abdomen. Book lung covers large, ovoid, without setae. Pedicel tube short, ribbed, with small, dorsolateral, triangular extensions, scuto-pedicel region lower than diameter of pedicel, with nearly straight scutal ridges (
Fig. 5
G), scutum not extending far dorsal of pedicel. Sperm pore small, transverse; posterior spiracles connected by groove (
Fig. 5
H); posteriorly directed apodemes present. Palp (
Figs
5
I, J, 7A–C): patella 0.29 long, 0.16 wide, attached to femur at 0.42; cymbium completely fused to bulb, no seam visible; bulb long and narrow, with distal tip slightly bent medially.
Female. As in male except as noted. Habitus as in
Fig. 6
A–C. Body length 1.66; carapace 0.69 long, 0.52 wide; abdomen 0.97 long, 0.56 wide. Endites without projections (
Fig. 6
F). Genitalia (
Figs 6
J, K, 7D, E): in ventral view with a stick-shaped dark spot (sds) in the middle of the anterior scutal ridge of postgynum; postgynum depression narrow, as wide as the distance between the lateral apodemes; paddle-like sclerite (pls) with thin straight arms in dorsal view; nail-like process (nlp) well separated; globular appendix (ga) small.
