Figs 7–8

Type material. Holotype: male, Cave without a name (04°56.322′S, 119°50.364′E, elevation 356 m), Benteng Orchard, Cenrana Village, Maros, South Sulawesi, Indonesia, 23 August 2014, H. Zhao and Z. Yao leg. Paratypes: 2 females, same data as holotype.

Etymology. The specific name refers to the type locality; adjective.

Diagnosis. This species resembles P. camba Huber, 2011 (see Huber 2011: 287, figs 1367, 1369–1370, 1400– 1401, 1435–1439) in having similar male chelicerae ( Fig. 8 D), appendix ( Fig. 8 C), and vulva ( Fig. 8 B) but can be distinguished by the absence of pointed proximal apophyses on the uncus ( Fig. 8 C), by the dorsally straight procursus ( Figs 7 C–D), and by the absence of knobs on the female external genitalia ( Fig. 7 A).

Description. Male (holotype): Total length 8.32 (8.65 with clypeus), carapace 1.91 long, 2.09 wide, opisthosoma 6.41 long, 1.44 wide. Leg I: – (19.23 + 1.01 + 19.68 + – + –), leg II: – (12.95 + 0.96 + 12.82 +20.64 + –), leg III: 32.02 (9.42 + 0.81 + 8.01 + 12.18 + 1.60), leg IV: 44.56 (12.82 + 0.91 + 11.03 + 17.56 + 2.24); tibia I L/ d: 94. Distance PME-PME 0.63; diameter PME 0.18; distance PME-ALE 0.06; distance AME-AME 0.09; diameter AME 0.09. Sternum wider than long (1.35/0.1.15). Habitus as in Figs 8 E–F. Carapace yellowish, with broad brown marks extending to ocular area; ocular area brown; clypeus yellowish, with brownish marks; sternum brown. Legs brown, distal parts of femora and tibiae whitish, darker rings absent. Opisthosoma pale grey, with broad brown bands medially. Ocular area elevated; each eye triad on top of a long, laterally directed eye-stalk (as in P. tharnlodensis sp. nov., cf. Fig. 31 A). Thoracic furrow absent. Chelicerae as in Fig. 8 D, with a pair of proximolateral apophyses. Pedipalps as in Figs 7 A–B; trochanter with a short ventral apophysis; procursus large and simple, with a spine-like process distally; uncus small; appendix hooked; embolus weakly sclerotized. Retrolateral trichobothrium of tibia I at 4.4%; legs with short vertical setae on tibiae, metatarsi and tarsi; without spines and curved setae.

Female: Similar to male, habitus as in Figs 8 G–H. Total length 7.53 (7.92 with clypeus), carapace 1.82 long, 2.09 wide, opisthosoma 5.71 long, 1.62 wide; tibia I: 15.45; tibia I L/d: 74. Distance PME-PME 0.39; diameter PME 0.18; distance PME-ALE 0.05; distance AME-AME 0.06; diameter AME 0.08. Sternum wider than long (1.26/1.13). Ocular area without eye-stalks. External genitalia ( Fig. 8 A) without knob. Vulva ( Fig. 8 B) with a sclerotized anterior arch and two elliptic pore plates.

Distribution. Indonesia (South Sulawesi, type locality; Fig. 32 ).

Natural history. The species was found in the entrance zone of the cave.
