Description of the male of Pozonia bacillifera (Araneae: Araneidae)

Abstract

Pozonia Schenkel, 1953 is a genus of Neotropical orb-weaving spiders that currently includes four species, three of which are known only from females. In this paper, the male of Pozonia bacillifera (Simon, 1897) is described and illustrated for the first time, based on a specimen from Nova Lima, state of Minas Gerais, Brazil. It differs from the male of P. nigroventris (Bryant, 1936), the only other known male of the genus, in characters of the genitalia, such as the larger embolus and the smaller ventral lobe of the paracymbium, as well as in the shape of the sternum. This represents the first record of P. bacillifera for the region. © 2011 Sociedade Brasileira de Zoologia.
