Genus Sundalema Zhao & Li gen. nov.
Type species.
Sundalema bonjol sp. nov. from West Sumatra Province, Indonesia.
Etymology.
The generic name is derived from “Sunda”, referring to Sundaland (distributional range of this genus), and “-lema” is a convention from the type genus of the family. Feminine in gender.
Diagnosis.
Females belonging to Sundalema gen. nov. can be distinguished from those of other genera by the following: a sclerotized and spiral receptacle (Fig. 24A View Figure 24 ) (vs. unsclerotized or not spiral). Males belonging to Sundalema gen. nov. resemble species in the bailongensis -group by having a long embolus but can be distinguished by the embolus lacking a spiral ridge and being nearly L-shaped (Fig. 25B-D View Figure 25 ) (vs. a distinct spiral ridge present on the nearly straight embolus).
Description.
Total length: 0.98-1.10 (male), 1.05-1.25 (female). Carapace 0.44- 0.58 long. Sternum light brown or milky white, with several sparse setae. Six vestigial eyes or ringed with black. Leg formula: 1-2-4-3, tibia I 0.90-1.27 long, leg glands belt-shaped (Fig. 1E View Figure 1 ). For females, neck of receptacle membranous, receptacle spiral, its dorsal part sclerotized, coiled into 1.25 to 2.5 loops. For males, cymbial apophysis tiny, present meso-prolaterally; embolus long relative to bulb, nearly L-shaped, lacking spiral ridge. Abdomen blue or pale brown with several long setae.
Composition.
Sundalema acicularis comb. nov., S. anguina (Wang & Li, 2010) comb. nov., S. bonjol sp. nov., and S. khaorakkiat sp. nov.
Distribution.
Southeast Asia (Thailand and Indonesia, sites 9-12 in Fig. 33 View Figure 33 ).
Comments.
The females of this genus are easily distinguished from all other genera, as their receptacles are long, spiral, and sclerotized; thus, a female has been chosen to represent the holotype.
