Complementary description.
Penis (
Figs 5
A–C):
Malleus slightly swollen, not surrounding the basal portion of lamina parva, which is funnel shaped with one sulcus on dorsal face. Chaetotaxy: MS A–B cylindrical: A1–A3 inserted lateroventrally, forming a row, B1 inserted and oriented ventrally. MS C cylindrical and sharp, reduced to two curved pairs and placed sub-distally. MS D: reduced to one well-developed pair, which is cylindrical and sharp, placed basally on lamina parva. MS E absent.
Variation:
Chelicerae: Segment II slightly swollen, barely distinguishable from female.
Distribution (
Fig. 8
):
Brazil
: Amazonas: Reserva Ducke; Fazenda UFAM,
New record
; Rio Preto da Eva,
New record
; ZF-2 road, Km 18,
New Record.
Justification of the new combination:
the chaetotaxy of this species is more similar to
Verrucastygnus caliginosus
(Pinto-da-Rocha, 1990) than to
Auranus
spp.. The general shape of the pars distalis also suggests this species is closer to
Verrucastygnus
: lamina parva with straight lateral margins, slightly concave distal margin, and malleus slightly swollen but not covering the basis of lamina parva.
