Type material. Holotype: Male from Floresta Nacional Contendas do Sincorá [13°46'– 14°00' S; 41°03'– 41°10' W], Contendas do Sincorá, Bahia, Brazil, October 2007 – November 2008, Y.G. Santos, deposited in IBSP 116090.
Paratypes: BRAZIL: Bahia: Contendas do Sincorá (Floresta Nacional Contendas do Sincorá) [13°46'– 14°00' S; 41°03'– 41°10' W], 63 7Ƥ, October 2007 – November 2008, Y.G. Santos (IBSP 116079–116081, 116087, 116089, MZSP 28953, 28954).
Other material examined. BRAZIL: Bahia: Contendas do Sincorá (Floresta Nacional Contendas do Sincorá) [13°46'– 14°00' S; 41°03'– 41°10' W], 133 28Ƥ, October 2007 – November 2008, Y.G. Santos (IBSP 116091–116120)
Etymology. The specific name is a noun in apposition that refers to the type locality.
(Fig. 23–25). They are distinguished from S. yssaiapari and S. tyaiamiri by the longer sclerotized hook arising from a prominent hump (Fig. 24) and from Scytodes tapacura n.sp. by the very wide retrolateral keel (Figs. 24–25). The females resemble those of Scytodes tapacura n.sp. (Fig. 6), S. yssaiapari (Rheims & Brescovit 2006: 302, fig. 26) and S. tyaiamiri Rheims & Brescovit 2006: 302, fig. 30) by the vulva with small spermathecae on long stalks, adjacent to large hyaline pockets (Fig. 27). They are distinguished from Scytodes tapacura n.sp. and S. yssaiapari by the conical hyaline pockets and from S. tyaiamiri by the shorter spermathecae and larger hyaline pockets (Fig. 27).
