Tenedos persulcatus Jocqué & Baert, 2002: 112–114 , figs 31A–C. (Male holotype from Río Negro, Oriente , Ecuador, 1600m, IV.1965, J. & N. Leleup leg., deposited in Koninklijk Belgisch Instituut voor Natuur-wetenschappen, Brussels, Belgium, not examined).

Material examined. COLOMBIA. Norte de Santander: Toledo, Parque Natural Nacional Tamá, Leaf litter, Winkler extractor, 1000m [7°17′52.11″N, 72°15′16.56″W], V. Rodríguez leg., 22.VII.1999, 1 ♂ (ICN-Ar-12314), 1 ♀ (ICNAr-8010) .

Diagnosis. Males of Tenedos persulcatus Jocqué & Baert, 2002 , resemble those of T. neitai sp. n. by general shaped and organization of the palpal structures ( Figs 58A–D ; 59A–B ; 61A–D ; 62A–B ), but are distinguished of the remain species by having very long and thin retrolateral tibial apophysis (RTA) with a groove along of its extension, with modified base, conductor (C) ending as strongly sclerotized appendix without other projections; long and membranous median apophysis (MA) (see Jocqué & Baert, 2002: 113, fig. 31 A–C; figs 58A–D; 59A–B). Females can be recognized by very long and coiled seminal receptacles on small spermathecae ( Figs 58E–F ; 59C–D ).

Remark. It was not possible to examine the type material of this species. The specimens herein referred were collected in Norte de Santander department and compared with the original illustrations made by Jocqué & Baert (2002). Otherwise, the female was collected together with males and their abdominal spots patterns are similar, allowing us to deduce their co-specificity. Males and females of this species presents remarkably differences on genital morphology, which are unusual in the remaining species of barronus group, however, due scare additional morphological evidence these species are provisionally placed in this group.
