Notes on Entypesa (Araneae: Nemesiidae) in the Field Museum of Natural History, with Descriptions of Four New Species from Madagascar

Four new Malagasy species of Entypesa Simon, 1902, E. andohahela sp. nov. (♂♀), E. enakara sp. nov. (♂), E. fisheri sp. nov. (♀), and E. rastellata sp. nov. (♂), are diagnosed and described from specimens deposited in the Field Museum of Natural History (Chicago, USA). All of them are clearly distinguishable from the known Madagascan congeners E. nebulosa Simon, 1902 and E. annulipes (Strand, 1907a), in details of colouration and structure of the eye group and spinnerets. In three of the four new species the males are known; they differ from males of the only South African congener, E. schoutedeni Benoit, 1965, in structure of the palpal tibia, configuration of the embolus, and the shape and armament of leg I. Data on the features of the hitherto known members of Entypesa are also provided.
