Two new species and new records of Syntrechalea (Araneae: Lycosoidea: Trechaleidae) from Brazil

Abstract

Currently, nine species of Syntrechalea F.O. Pickard-Cambridge, 1902 are known, six of them occurring in Brazil. In this study, two new species of of this genus are described and illustrated from the states of Amazonas and Tocantins, northern Brazil. Syntrechalea neblina sp.nov. can be distinguished from all known species by the bifurcated guide of the median apophysis. Syntrechalea robusta sp.nov. can be distinguished from all known species by the wider and concave ectal division of the retrolateral tibial apophysis. Additionally, new records of S. adis Carico, 2008, S. brasilia Carico, 2008, S. caporiacco Carico, 2008, S. napoensis Carico, 2008, S. syntrechaloides (Mello-Leitão, 1941) and S. tenuis F.O. Pickard-Cambridge, 1902 are provided
