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 View FIGURES 22 – 31. 22 – 27 ). They are distinguished from S. yssaiapari and S. tyaiamiri by the longer sclerotized hook arising from a prominent hump ( Fig. 24 View FIGURES 22 – 31. 22 – 27 ) and from Scytodes tapacura n.sp. by the very wide retrolateral keel ( Figs. 24–25 View FIGURES 22 – 31. 22 – 27 ). The females resemble those of Scytodes tapacura n.sp. ( Fig. 6 View FIGURES 1 – 9. 1 – 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 View FIGURES 22 – 31. 22 – 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 View FIGURES 22 – 31. 22 – 27 ).
