Justification of the synonymy. Leucauge argyroaffins was described by Soares and Camargo (1948) based on a single male collected in Nova Xavantina, state of Mato Grosso ( Fig 1A View FIGURE 1 ). This specimen is damaged, having lost both palps and most of the color pattern, but the chelicerae remain undamaged, where a distal constriction typical of L. argyra is seen. The authors used two main diagnostic features to differentiate L. argyroaffins from L. argyra : the shape of the cymbial hook and the presence of a dorsobasal process, against its supposed absence on L. argyra , which is inaccurate. The fig. 40 of their work depicts a palp with these structures, same as those presented by L. argyra males. It should be noted that the curvature of the cymbial hook is not a reliable diagnostic feature because it may vary slightly within populations. Furthermore, in the original description of the L. argyroaffins holotype, the color described for the male is the same as that shown by L. argyra . The combination of these factors led us to propose the synonymy of these species.

Diagnosis. This species differs from most congenerics by its unique genitalia: females are distinguished by their projected epigynum with a ventral process ( Fig 1B View FIGURE 1 ) only shared with the species herein described (see below), but differ by the conical shape of the projection. Males share the presence of dorsobasal process covered with setae with of Leucauge globosa (O. Pickard-Cambridge, 1889) , but L. argyra differs by the presence of a very sclerotized sickle-shaped conductor, bigger body size (more than 4 mm) and thicker legs. The species described below and L. argyra are the only known to possess the cymbial hook, however L. argyra is distinct for carrying both cymbial apophyses. ( Fig 1D View FIGURE 1 ).
