MATERIAL EXAMINED. Venezuela, Falcón Province, 56♂ 42♀ 138 juvs, 2006. Ecuador, Morona-Santiago Province, south of Yaupi , 38♂ 24♀ 86 juvs, direct descendants of the of the holotype female and paratype male of T. ythieri collected by local Indians. Hybrids No. 1, 12♂ 9♀ 2juvs. (♀ from Venezuela and ♂ descendants of the holotype female and paratype male of T. ythieri ), 26 juvs. descendants of the hybrids No. 1. Hybrids No. 2, 8♂ 5♀ 11juvs. (♂ from Venezuela and ♀ descendants of the of the holotype female and paratype male of T. ythieri ), 21 juvs. descendants of the hybrids No. 2. All specimens were reared by first and fifth authors in 2004–2008, and are in first author’s collection ( FKCP) .

DIAGNOSIS. Adults 45 – 72 mm long. Females mature after fifth ecdysis; males mature after fourth or fifth ecdysis, which determines their final size. Base color reddish yellow to dark reddish (depending on age), young spotted. Pectinal teeth number 17 – 23. Subaculear tooth short and strongly spinoid. Basal middle lamella of female pectines dilated. Fixed and movable fingers of pedipalps with 14/16 rows of granules that include external and internal granules. Movable finger with minute basal tubercle in both sexes. Ventral carinae of third and fourth metasomal segments in Y-shaped configuration. Manus of pedipalp narrower in female than in male. Metasoma slightly longer in male than in female.
