Verrucastygnus hoeferscovitorum View in CoL (Pinto-da-Rocha, 1997) comb. nov.

( Figs 5 View FIGURE 5 A–C, 6F, 7F)

Auranus hoeferscovitorum Pinto-da-Rocha, 1997: 263, figs 311–316, 527–528, 602; Kury 2003: 228. (Type MCZN 1099, male holotype, not examined).

Complementary description. Penis ( Figs 5 View FIGURE 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 View FIGURE 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.
