On the identity of the type species of Actinopus tarsalis (Araneae: Actinopodidae)

Abstract

The type species of the Neotropical Actinopus, A. tarsalis Perty, 1 833, is redescribed based on material from the type locality, the state of Piaui, Brazil. The species appears to be restricted to northeastern Brazil and is newly recorded from the state of Sergipe. An old record from the state of Rio Grande do Sul is rejected. Actinopus tarsalis differs from other species of the genus by details of the male copulatory bulb: tegular apophysis absent, robust embolar base, inserted basally at a right angle (90°); embolar apices apex flattened and expanded, arrow-shaped in dorsal view. © 2012 Sociedade Brasileira de Zoología.
