Synaphosus femininis Deeleman-Reinhold, 2001: 538 , f. 929-930 (♀); Wang & Zhang, 2015: 438, f. 1‒19 (♂♀).

Material examined. LAOS, Luang Nam Tha Province: 1♂ 1♀ (ZMF), Luang Nam Tha, Ban Tavan 1, 581 m, 20°58.702'N, 101°28.686'E, small secondary forest, leaf litter, close to stream, sieving, 2.03.2008 (P. Jäger) ; 1♀ ( ZMMU), Luang Nam Tha, Ban Tavan , 586 m, 20°58'57.6"N 101°29'57.6"E, valley with stream, bushes, sieving, 7.03.2008 (P. Jäger).

Note. The new species belongs to the femininis group of species.

Diagnosis. Synaphosus femininis is most similar to S. jaegeri sp. n. from which it can be distinguished by longer retrodorsal tibial apophysis, droplet-shaped cymbium with distinct tapering tip (but not egg-shaped), threedimensional conductor partly encircling the tip of the cymbium, a longer epigynal scape, thinner copulatory ducts with 13‒14 (vs. 6) closely spaced coils.

Description. Male. Total length 4.25. Carapace: 1.85 long, 1.53 wide. Eye sizes and interdistances: AME 0.11, ALE 0.12, PME 0.14, PLE 0.12, AME‒AME 0.03, AME‒ALE 0, PME‒PME 0.08, PME‒PLE 0.03, ALE‒PLE 0.03; MOQ length 0.31, front width 0.23, back width 0.29. AME surrounded by black edge. Carapace yellowbrown. Chelicerae, maxillae and labium light-brown. Sternum yellow-brown with dark brown thin edge. Legs and palps yellow-brown. Abdomen grayish with trapeziform scutum. Scutum anteriorly with long setae.

Leg measurements in ♂.

Spination of legs in ♂.

Palp as in Figs 8‒11 ; femur and patella not modified; tibia with retrolateral conical outgrowth (To) and long dorso-retrolateral apophysis (Ta) bifid on the tip, tibial apophysis 2.5 times longer than tibia in retrolateral view, and as long as 2/3 of cymbium; cymbium droplet shaped in dorsal view, smoothly rounded in lateral view; bulb bean-shaped in lateral view with concave ventral part, conductor (Cd) very large (larger than cymbium), covers almost whole tegulum, 3-dimensional; tip of conductor (Tg) small tongue-like (labeled as tegular apophysis in Wang & Zhang, 2015); embolus (Em) filamentous, originating at 6 o'clock position, base of embolus with basodorsal outgrowth (Eb).

Female. Total length 4.13. Carapace: 1.65 long, 1.28 wide. Eye sizes and interdistances: AME 0.09, ALE 0.11, PME 0.11, PLE 0.11, AME‒AME 0.02, AME‒ALE 0, PME‒PME 0.06, PME‒PLE 0.06, ALE‒PLE 0.06, MOQ 0.27 long, front width 0.21, back width 0.23. AME with black margins. Coloration like in males. Abdomen without scutum.

Leg measurements in ♀.

Epigyne as in Figs 5‒7 , 12‒13 ; very long, with oval shaped short scape (Sc) located close to petiolus; area between scape and coiled insemination ducts (Id) with transversal furrow; copulatory openings (Co) located in centre of epigyne; insemination ducts first run anteriorly, and then form about 13‒14 coils located one over another; receptacles (Re) round.

Distribution. Currently, the species is known from Eastern Java, Pujon Pass (type locality), three localities in Hainan ( Wang & Zhang 2015) and one locality in Laos (present data). The Laotian locality is the northernmost and westernmost locality of the range.
