Figs 9-10 View Figs 1 - 10 , 19-21 View Figs 11 - 21

Holotype: Male; Indonesia, Sumatra, Jambi Province, Mt Kerinci, footpath to summit, N of Kersik Tua , 2160 m a.s.l., montane rain forest, sifting; 17.-18. II.2000; leg. P. Schwendinger [Sum-00/13].

Other material examined: MHNG; male holotype of Prosoponoides hamatum Millidge & Russel-Smith, 1992 . – MHNG; male holotype of P. simile Millidge & Russel-Smith, 1992 . – MHNG; male holotype of Kenocymbium deelemanae Millidge & Russel-Smith, 1992 .

Etymology: The specific epithet is a noun in apposition referring to the “terra typica”, the Jambi Province.

Diagnosis: The new species is characterized by the strongly reduced distal part of the paracymbium, by the thick and long embolus, as well as by the presence of a long, downward-directed process on the convector .

Description: Male (holotype). Medium-sized Linyphiinae , total length 2.30, habitus as shown in Fig. 9 View Figs 1 - 10 . Carapace 1.05 long, 0.80 wide, unmodified, reddish brown, with darkened cephalic part and indistinct grey radial stripes as well as with darker margin; sulci absent. Chelicerae 0.50 long, mastidion absent. Legs reddish brown, end of segments darkened. Fe I 1.50 long. Leg IV 3.95 long (1.05+0.25+0.95+1.10+0.60). Chaetotaxy. FeI: 1-2- 0-0, II-IV: 1-0-0-0; TiII: 2-1-1-0, III: 2-0-0-1, IV: 2-1- 0-0. TmI 0.22. Metatarsus IV without trichobothrium. Palp ( Figs 10 View Figs 1 - 10 , 19-21 View Figs 11 - 21 ): Proximal part of paracymbium triangular and projecting forwards, distal part short, narrow, slightly curved, transparent, poorly visible. Distal suprategular apophysis small, claw-shaped.

Embolus thick, slightly bent. Embolic membrane a long, narrow stripe. Radix large, flat, with a long apophysis directed downwards. Abdomen 1.20 long, 0.70 wide, dorsal pattern as shown in Fig. 9 View Figs 1 - 10 .

Female. Unknown.

Taxonomic remarks: The new species is similar to Prosoponoides hamatum , known from northern Sumatra, but clearly differs by a twice shorter distal part of the paracymbium (not shown on palp illustrations of P. hamatum in Millidge & Russel-Smith, 1992 ), as well as by its thick embolus and the presence of a specific process on the convector .

Distribution: Known only from the type locality on Sumatra Island, Indonesia.
