Nesticella foelixi new species

Figs 18–19, 28, 40

Type material. Holotype male. LAOS: Bolikhamsay Province: Lak Sao, 18°12 ' 41.6"N, 104°50 ' 26,6"E, 551 m elevation, cool valley, bed of a stream, dry, at day, P. Jäger & S. Bayer leg. by sieving, 10.11.2009 (SMF).

Etymology. The species name honours our dear colleague Rainer Foelix who provided excellent photographs of the so-called “pipette setae” for this study. Moreover, his text book on the biology of spiders is one of the famous books which is known worldwide and piqued the second author’s curiosity about spiders; noun (name) in genitive case.

Diagnosis. Nesticella foelixi n. sp. can be easily recognized from all Nesticella species by the spoon-shaped part of the terminal apophysis and the pliers-shape dorsal process of the paracymbium (Fig. 18).

Description. Male (holotype). Total length 1.80; cephalothorax 0.90 long, 0.80 wide; abdomen 1.00 long, 0.70 wide. Eye measurements: AME 0.04; ALE 0.09; PME 0.09; PLE 0.09; AME–AME 0.04; AME–ALE 0.01; PME–PME 0.04; PME–PLE 0.02; AME–PME 0.04; ALE–PLE 0.00; clypeus–AME 0.18; clypeus–ALE 0.12. Leg formula: I, IV, II, III; measurements of palp and legs: palp: 1.18 (0.39, 0.19, 0.18, 0.42); I: 4.84 (1.40, 0.38, 1.30, 1.20, 0.56); II: 3.96 (1.14, 0.34, 1.05, 0.92, 0.51); III: 2.94 (0.84, 0.29, 0.68, 0.63, 0.50); IV: 4.41 (1.30, 0.35, 1.23, 0.97, 0.56).

Palp as in diagnosis. Embolus strongly developed and thickened. Paracymbium bifurcate. Dorsal process in ventral view pliers-shaped. In retrolateral view ventral branch of the dorsal process emarginate. Ventral process in ventral view flat. Distinct terminal apophysis, overlap the conductor considerably in retrolateral view.

Female. Unknown.
