Gao, Cai-Xia & Li, Shu-Qiang, 2014, Comb-footed spiders (Araneae: Theridiidae) in the tropical rainforest of Xishuangbanna, Southwest China, Zoological Systematics 39 (1), pp. 1-135 : 130-132

Yunohamella gibbosa sp. nov. ( Figs 107–109 )

Holotype ♂, China, Yunnan, Xishuangbanna, Menglun , primary tropical seasonal rainforest (21º55.035'N, 101º16.500'E), 22 July 2007, Guo Zheng leg.

Etymology. The specific name derives from the Latin adjective gibbosus and means humpbacked, in reference to the conductor with 2 apophyses, shaped like humpback.

Diagnosis. The new species is somewhat similar to Y. lyrica , but can be distinguished by having the embolus strong; conductor with 2 apophyses; tegulum narrow. The latter species has a slender embolus; conductor curved, with acute end; tegulum very large (Levi, 1957a).

Male (measurements of holotype). Total length 1.60. Prosoma 0.70 long, 0.63 wide, yellow, with black stripes and long setae. Sternum 0.50 long, 0.50 wide, grey with setae. Opisthosoma 0.88 long, 0.63 wide, pale, with large black stripes, tiny black spots, without colulus. Eye measurements: AME 0.09, ALE 0.08, PME 0.08, PLE 0.08, AME-AME 0.08,

Chelicerae: yellow, with black spot, 2 anterior teeth; fangs long and slender. Endites: 0.28 long, 0.13 wide, yellow to grey, with brown pro-edges. Labium fused with sternum, 0.09 long, 0.15 wide, with 4 setae, yellow to grey. Leg measurements: I 5.49 (1.75, 0.38, 1.50, 1.55, 0.31); II 3.83 (1.25, 0.35, 0.90, 0.88, 0.45); III 2.25 (0.70, 0.15, 0.45, 0.55, 0.40); IV 3.48 (1.10, 0.25, 0.88, 0.80, 0.45).

Leg II, leg IV similar to leg I; femur III with black spot; tibia III–tarsus III with black spot. Pedipalpus ( Figs 107A–B , 108A–B , 109A–D ): tibia yellow, with 2 trichobothria, black spot; cymbium yellow, with large black spot; paracymbium hooded; subtegulum broad; tegulum confined; median apophysis smooth, without apophysis; embolus short, strong; conductor with 2 apophyses; tegular apophysis indistinguishable.
