Abstract

The genus Pycnothele Chamberlin, 1917 is revised. The Brazilian species Pycnothele perdita Chamberlin, 1917, P. singularis (Mello-Leitão, 1934) and P. auronitens (Keyserling, 1891) are redescribed, diagnosed and illustrated. The females of P. auronitens and P. singularis are described for the first time and P. auripila (Mello-Leitão, 1946) from Uruguay, currently a junior synonym of P. auronitens, is revalidated. Pycnothele piracicabensis (Piza, 1938) is transferred to Rachias Simon, 1892, with which it shares the morphology of the sexual structures, restoring the original combination. Five new species are proposed for Brazil: Pycnothele rubra sp. nov., P. jatai sp. nov. and P. araraquara sp. nov., from state of São Paulo, P. arapongas sp. nov., from state of Paraná, and P. gauderio sp. nov., from state of Rio Grande do Sul. After this revision the genus includes ten Neotropical species. Maps with distribution of all species is presented for the first time and the occurrence of species of the genus is enhanced for the Brazilian state of Paraná. (AU)
