INTRODUCTION

The genus Nyssodrysternum was described by Gilmour (1960:59) for N. fasciatum from Brazil (Bahia, Rio de Janeiro). The same author (1963:3) proposed Nyssodrystes as a new name for Nyssodrys Bates, 1864. Monné (1975:248) described Nyssodrysternum rubiginosum and N. spilotum from Brazil (Paraná), and the same author (1985:536) established the synonymy between Nyssodrysternum Gilmour, 1960 and Nyssodrystes Gilmour, 1963 and described nine species, mainly from the Amazon basin. Monné (1992:773) described four species from southern and southeastern Brazil, Monné & Machado (2009:67) established the synonymy between Nyssodrysternum and Pseudoleiopus Breuning, 1970 and between Nyssodrysternum lemniscatum Monné, 1985 and Pseudoleiopus borneanus Breuning, 1970, finally Monné (2009:324) described N. cingillum from Bolivia. Nyssodrysternum had so far included forty five species, here we add fifteen new species.

Nyssodrysternum vanini sp. nov.

(Fig. 6)

Etymology: The epithet is an acknowledgment to the colleague Dr. Sergio A. Vanin, (MZSP), who collect one of the specimens.

Male: Integument dark brown. Pubescence predominantly dark brown. Pubescence gray-yellowish: head with a narrow line surrounding the eyes; pronotum with seven longitudinal stripes, the median one very narrow, the external broader.
