Abstract

The species of the genus Centroctenus can be distinguished from other Ctenidae genera by the presence of a long tibiae and the absence of a retrolateral projection of the cymbium in the male palp, and by the presence of a rounded spermathecae in the female epigynum. The composition of this spider genus is herein expanded to eleven Neotropical species, with the description of six new species: Centroctenus dourados sp. n., C. claudia sp. n., C. chalkidisi sp. n., and C. varzea sp. n., from Brazil; and Centroctenus coloso sp. n. from Colombia and Centroctenus alinahui sp. n. from Ecuador. A map with the distribution of all known species in the genus is presented.
