Diagnosis

Males differ from those of other species by the short and slender embolus (Figs 12–14). Females differ by the non-spiraled spermathecae, lacking lobes, diverging on their base and converging on their distal portions (Fig. 15). Additionally, males and females have cephalothorax brown and abdomen dorsally black with two series of four red spots extending laterally. Carapace, dorsum of chelicerae and most anterior dorsal region of abdomen with very long, yellow, stiff setae (Fig. 25).

Etymology

The specific name is a matronym in honour of Miriam Costa, who collected the holotype and several other new spider species during several years she worked at Instituto Butantan.

Types

Holotype female, Brazil, state of Tocantins, Palmas, U.H.E. Luis Eduardo Magalhães [10°12'S, 48°24'W], 211 m.a.s.l, during faunal rescuing, M. Costa and D. Candido, 12 January 2002 (IBSP unnumbered); Paratype male, Brazil, state of Tocantins, Lajeado, (9°46'4.85"S, 48°21'6.69"W), 226 m.a.s.l, G. Puorto, R. Martins, I.
