Diagnosis.

The new species is similar to O. codalmasi Wunderlich, 2011 (female unknown) and O. longituba sp. nov. in the strongly coiled sperm duct and the enlarged palpal tibia, but can be distinguished from O. codalmasi by the very long tube-shaped embolus (vs short; cf. Fig. 21 A, B, D and Wunderlich 2008: fig. 7); from O. longituba by palpal tibia wider than bulbus (vs narrower; cf. Fig. 21 A, B and Fig. 12 A, B), the tongue-shaped labium (vs diamond-shaped; cf. Fig. 21 C and Fig. 12 C) and the saddle-shaped marking on epigaster (vs lacking; cf. Fig. 20 H and Fig. 11 H).

Description.

Male (holotype). Body: habitus as in Fig. 19 A – C; body length 1.05. Carapace (Fig. 19 E, G): 0.58 long, 0.41 wide. Eyes as in Fig. 19 D, E. Clypeus as in Fig. 19 D. Sternum (Fig. 19 F): longer than wide. Mouthparts (Figs 19 F, 21 C): labium tongue-shaped, not fused to sternum; endites strongly sclerotized, with serrula in single row, outer margin smoothly curved. Abdomen: ovoid, 0.58 long; dorsum soft portions pale white, without color pattern. Legs: yellow, without color pattern; femur IV thickened, wider than femora I-III. Palp (Fig. 21 A, B, D, E): tibia strongly enlarged, length / width = 1.49, cymbium elongated ovoid; bulb pear-shaped in lateral view, with ventral side strongly protruding proximally, ca 0.99 × as wide as tibia; the sperm duct with two loops in prolateral view; embolus long tube-shaped, with a basal node (Fig. 21 A, B).

Female (SYNU -1559). Same as male except as noted. Body: habitus as in Fig. 20 A – C; body length 1.20. Carapace (Fig. 20 E, G): 0.59 long, 0.42 wide. Abdomen: 0.62 long. Epigaster (Fig. 20 H): without special external features, with a saddle-shaped marking visible through cuticle.

Endogyne (Fig. 21 F, G): with stout medial clavate sclerite (AUS), provided with pair of long lateral protrusions (Pr); anterior receptaculum (ARe) rounded, semitransparent, slightly longer than AUS; posterior plate (PP) present, large.

Distribution.
