Ordo: Araneae
Familia: Psilodercidae
Genus: Psiloderces
Name
Psiloderces grohotensis Li & Chang sp. nov. – Wikispecies link – ZooBank link – Pensoft Profile
Types
Holotype: ♂ (IZCAS), Indonesia, East Kalimantan, Tanah Grohot, 1°48.6260'S, 115°51.1250'E, 62 m, 20.VIII.2017, H. Liu & Z. Chen. Paratype: 1♀ (IZCAS), same data as holotype.
Etymology
The species name is an adjective referring to the type locality.
Diagnosis
Males of P. grohotensis sp. nov. can be distinguished from all other species of the genus by the structure of the bulb which has 2 bulges, and a laminar apophysis connected to the embolus (Fig. 19B) (vs. one bulge or absent); the female can be distinguished by transversal, tubular spermathecae resembling caterpillars (Fig. 18A) (vs. the absence of transversal, tubular spermathecae).
Description
Male (Holotype). Total length 1.30; carapace 0.50 long, 0.60 wide; abdomen 0.80 long, 0.50 wide. Carapace round and pale brown, with trident dark brown stripes medially and dark brown bands laterally (Fig. 18C). Chelicerae pale brown (Fig. 29D). Clypeus slanting, dark brown. Endites dark brown, light brown basally. Labium dark brown, delimiting pair of light brown circular dots. Sternum dark brown. Abdomen elongated, dorsum with indistinct brownish stripes, antero-ventrally with pair of circular dark brown patches followed by elliptical light brown patch, posterior dark brown, delimiting light brown dotted vertical lines laterally and V-shaped medially. Legs uniformly brown; measurements: I 7.47 (2.00, 0.20, 2.25, 2.00, 1.02), II 5.85 (1.60, 0.20, 1.75, 1.50, 0.80), III 4.10 (1.09, 0.16, 1.20, 1.10, 0.55), IV 6.00 (1.60, 0.20, 1.80, 1.60, 0.80). Palp (Fig. 19A–D): femur slender, 4 times longer than patella; patella not swollen; tibia 2.5 times shorter than femur; cymbium 1.5 times shorter than femur, protrusion darkens distally; bulb pale brown, diamond-shaped with embolus and laminar apophysis located distally; embolus thin, connected basally with laminar apophysis; 2 acute bulges directed ventrally (Fig. 19B) Female (Paratype). General features and coloration similar to those of male (Fig. 18D, E). Measurements: total length 1.49; carapace 0.47 long, 0.55 wide; abdomen 1.02 long, 0.78 wide. Leg measurements: I 3.96 (1.30, 0.16, 1.50, 1.30, 0.70), II 4.91 (1.25, 0.16, 1.50, 1.30, 0.70), III 3.89 (1.00, 0.13, 1.13, 1.00, 0.63), IV 5.41 (1.38, 0.13, 1.70, 1.40, 0.80). Endogyne (Fig. 18A): spermathecae tubular, elongate mesally, median tips pointed, lateral ends rounded, receptacles separated by about 3 diameters (Fig. 18A).
Distribution
Known only from the type locality (Fig. 30).
