Diagnosis.

The new species is similar to Orchestina codalmasi Wunderlich, 2011 (female unknown) and Orchestina sublongituba 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. 12 A, B, D and Wunderlich 2008: fig. 7); from O. sublongituba by palpal tibia narrower than bulbus (vs wider; cf. Fig. 12 A, B and Fig. 21 A, B), the diamond-shaped labium (vs tongue-shaped; cf. Fig. 12 C and Fig. 21 C) and the obscure marking on epigaster (vs saddle-shaped; cf. Fig. 11 H and Fig. 20 H).

Description.

Male (holotype). Body: habitus as in Fig. 10 A – C; body length 1.25. Carapace (Fig. 10 E, G): 0.54 long, 0.39 wide; yellow, oval in dorsal view. Eyes (Fig. 10 D, E): well developed, PME largest. Clypeus as in Fig. 10 D. Sternum as in Fig. 10 F. Mouthparts (Figs 10 D, F, 12 C): labium diamond-shaped, not fused to sternum, anterior margin not indented at middle; endites strongly sclerotized, with serrula in single row, out margin straight. 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. 12 A, B, D): tibia strongly enlarged, length / width = 1.61, cymbium elongated ovoid; bulb pear-shaped in lateral view, with ventral side strongly protruding proximally, ca 1.25 × as wide as tibia; the sperm duct with two loops in prolateral view; embolus long tube-shaped, with a basal node (Fig. 12 A, B).

Female (SYNU -1568). Same as male except as noted. Body: habitus as in Fig. 11 A – C; body length 1.28. Carapace (Fig. 11 E, G): 0.67 long, 0.48 wide. Abdomen: 0.61 long. Epigaster (Fig. 11 H): without special external features.

Endogyne (Fig. 12 E, F): with stout medial clavate sclerite (AUS), provided with pair of short lateral protrusions (Pr); lateral protrusions at angle of about 60 ° with medial clavate sclerite; anterior receptaculum (ARe) triangular, semitransparent, shorter than AUS; posterior plate (PP) present, large.

Distribution.

Known only from the type locality.

Etymology.

The specific name is derived from the Latin and refers to the long tube-shaped distal end of bulb.
