Colour. Type specimen alcohol faded brown. Live freshly moulted specimens from type locality are an overall blackish with longer red hairs on the abdomen, with grayish hairs on the dorsal trochanter, coxae and edges of the carapace, and two converging stripes on patella in older specimens (Fig. 2). These colours fade to overall
Originally, this species was described by "Carapace is decidedly longer than wide. Median depression transverse; deep" and "barely a trace of scopula on metatarsus IV". Our examination confirmed these features, but lead us to conclude identification as
as defined here, including presence of an apically swollen unilobar spermathecae (Fig. 1, see also Figs 3-5, 7-9, contrast 13-16). The type locality of Barro Colorado Island is the site of a Smithsonian Institute field-centre; hence there is a large series of specimens from type locality assignable to
