Remarks: All available specimens are distinctly smaller than the adult Malayathele gen. nov. specimens examined. The largest specimen (from Singapore; Fig. 2 View Fig , locality 20) has a vulva with fully developed lateral receptacles, which resembles that of M. kanching sp. nov. females. However, the absence of metatarsal preening combs and the presence of only two eyes (seemingly the AME) indicate that this represents an undescribed genus. The spider fauna of Singapore Island is quite well documented, but to our knowledge no such spiders have ever been reported from there. It is possible that they were actually collected, but ignored or discarded as juveniles. Obviously this species is obscure, but nevertheless widely distributed on Singapore and the Indonesian islands south of it. Singkep Island is over 200 km away from Singapore.
