Type material.
Holotype ♂ (SYNU-764): China, Yunnan Prov., Dali Bai Autonomous Pref., Dali City, Cangshan Mt., Dapojing, pitfall trapping in forest, 25°34′17"N, 100°08′15"E, 2600 m, Z. Yang leg., 25/1/2010; Paratypes 1 ♀ (SYNU-765), same data as holotype; 1 ♂ (SYNU-766), Cangshan Mt., Jishejing, pitfall trapping in forest, 25°40′29"N, 100°06′36"E, 2600 m, Z. Yang leg., 15/11/2008.
Diagnosis.
The new species is similar to O. apiculata Liu, Xiao & Xu, 2016 in the shape of the bulb and the long psembolus, but can be distinguished by the palpal tibia narrower than the bulb (Fig. 2A View Figure 2 ) vs. distinctly wider than the bulb in O. apiculata ( Liu et al. 2016: fig. 2A, B), triangular labium (Fig. 2D View Figure 2 ) vs. sub-circular ( Liu et al. 2016: figs 1E, 3H), and the tubular anterior uterine sclerite (AUS) (Fig. 3G, H View Figure 3 ) vs. broad and column-shaped ( Liu et al. 2016: fig. 2C, D).
Description.
Male (holotype). Body: habitus as in Fig. 1A, C, E View Figure 1 ; body length 1.33. Carapace (Fig. 1B View Figure 1 ): 0.74 long, 0.56 wide; yellow, oval in dorsal view, with net-shaped pattern, pars cephalica slightly elevated in lateral view, with rounded posterolateral corners. Eyes (Fig. 1B, F View Figure 1 ): well developed, nearly equal-sized; posterior eye row recurved from above. Clypeus (Fig. 1B, F View Figure 1 ): margin unmodified, curved downwards in front view, sloping forward in lateral view, high, ALE separated from edge of carapace by their diameter or more. Sternum (Fig. 1D View Figure 1 ): with marginal band and median dark brown patches; setae sparse, needle-like, evenly scattered. Mouthparts (Figs 1D, F View Figure 1 , 2D View Figure 2 ): chelicerae straight, anterior face unmodified; labium triangular, anterior margin not indented at middle, lateral margins slightly sclerotized, labium pattern darkly spotted but medially delimiting 2 pale, adjacent, oval areas; endites unmodified. Abdomen (Fig. 1A, C, E View Figure 1 ): 0.59 long; with gray net-like pattern; pedicel tube short, unmodified. Palp (Fig. 2A-C View Figure 2 ): tibia enlarged, length/width ratio = 1.41, more than 2 times as wide as femur; bulb pear-shaped, strongly enlarged, about 1.5 times as wide as tibia; psembolus nearly as long as bulb, whip-like, bent inwards.
Female (SYNU-765): Same as male except as noted. Body: habitus as in Fig. 3A, C, E View Figure 3 ; body length 1.63. Carapace (Fig. 3B View Figure 3 ): 0.74 long, 0.57 wide. Abdomen: 0.89 long. Epigaster: without special external features. Endogyne (Fig. 3G, H View Figure 3 ): with medial tubular sclerite (AUS) extending anteriorly, then flipped posteriorly, ending near epigastric furrow; dorsolateral extension (Ex) interrupted anteriorly.
Affinities.
The new species is similar to O. apiculata and O. clavigera Henrard & Jocqué, 2012 (from Kenya). Based on the long, whip-like psembolus, the tubular anterior uterine sclerite (AUS), and the weakly sclerotized endites, the new species should be classified in the macrofoliata -subgroup of the macrofoliata -group of Henrard and Jocqué (2012).
Etymology.
The specific name is a noun in apposition taken from the type locality.
