I place this species in the genus Breda on the basis of the structure
of the male palps and the epigynum, the reduction of leg spines,
the single simple tooth on the retromargin of the fang groove, the
features of the carapace, and the placement of the eyes. Mr. Banks
(29) had one female from Las Sabanas, R. P., July, 1924, but the
species has not appeared in my collection.

The Peckhams had mature females and an immature male. F.
Cambridge gave a very good figure of the male palp but almost no
description. Banks (’29) took a female and an immature male in the
Canal Zone Biological Area, June, 1924. Since no detailed descriptions
have ever been published I have considered it desirable to establish
hypotypes of both sexes and give here careful descriptions of the same.
Male hypotype. Total length 10.88 mm. Carapace 4.35 mm. long, 3.39 mm. wide a short distance behind PLE which occupy two thirds of width of carapace at their level, 1.53 mm. tall at level of PLE and, therefore, less than one half as tall as wide; depressed in middle of cephalic region and also lateral to PLE, PME and ALE so that these eyes stand up on a tuberculated ridge; region just posterior to PLE also depressed medially; seen in profile, rises gently to PLE, then descends again very gently to steep posterior declivity (Fig. 28); very hairy, with many long black bristles around eyes of which four groups seem to be most characteristic; a group of these consisting of five lies at some distance below PME, the other group of three lies behind and
