Brasilomma gen nov a new prodidomid genus from Brazil (Araneae Prodidomidae)

摘要

The genus Brasilomma gen. nov. is described to include B. enigmatica sp. nov. collected in three caves from the state of Minas Gerais, Brazil. This genus can be distinguished from the remaining South American Prodidomidae by the male palps with largetriangular projection, covering the base of the embolus, the distal border of the tegulum projected over the base of the conductor and median apophysis and by the female epigynum with blind, posterior atrium and anteriorly widened copulation ducts arising from an internal, mushroom-shaped plate. In addition, aspects of the species natural history are described.
