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 View Figure 21 and Wunderlich 2008: fig. 7); from O. longituba by palpal tibia wider than bulbus (vs narrower; cf. Fig. 21 A, B View Figure 21 and Fig. 12 A, B View Figure 12 ), the tongue-shaped labium (vs diamond-shaped; cf. Fig. 21 C View Figure 21 and Fig. 12 C View Figure 12 ) and the saddle-shaped marking on epigaster (vs lacking; cf. Fig. 20 H View Figure 20 and Fig. 11 H View Figure 11 ).

Description.

Male (holotype). Body: habitus as in Fig. 19 A – C View Figure 19 ; body length 1.05. Carapace (Fig. 19 E, G View Figure 19 ): 0.58 long, 0.41 wide. Eyes as in Fig. 19 D, E View Figure 19 . Clypeus as in Fig. 19 D View Figure 19 . Sternum (Fig. 19 F View Figure 19 ): longer than wide. Mouthparts (Figs 19 F View Figure 19 , 21 C View Figure 21 ): 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 View Figure 21 ): 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 View Figure 21 ).

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

Endogyne (Fig. 21 F, G View Figure 21 ): 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.
