Abstract

The male of Paratrechalea longigaster Carico, 2005 and the female of P. julyae Silva & Lise, 2006 are described and illustrated for the first time, and new records provided. Photomicrographs of the female genitalia showing accessory spermathecae for P. ornata (Mello-Leitão, 1943) and P. azul Carico, 2005 as well as the morphological variation of the epigynum in both species are also presented. A previously unreported feature of the male palpus common to both P. azul Carico, 2005 and P. ornata (Mello-Leitão, 1943) is also discussed.
