Hind trochanter with somewhat acute protuberance ( Figs 56–57 ). Tergites and sternites 6 and 7 as in Fig. 55 . Surstyli similar in shape, with hooked-tip, right surstylus slightly shorter ( Figs 58–59 ), both surstyli with tips downward-directed when examined in lateral view ( Figs 58–59 ). Apex of phallic guide short with stout dorsal spine, angled at about 25 degrees ( Fig. 60 ). Phallus branches with central branch bearing row of small spines, one of the lateral branches with one small spine ( Fig. 60 ). Ejaculatory apodeme sandal-shaped with apex rounded ( Fig. 61 ). Gonopods subsymmetrical, apexes acute, right gonopod slightly longer ( Fig. 62 ).

Material examined. COLOMBIA, Magdalena, PNN[Parque Nacional Natural] Tayrona, Neguanje , 11º20’N / 74º02’W, 10 m [eters], Malaise, 17–27.ix.2001, R. Henriquez leg, “M2136” (1♂, IAvH); “ idem, (1♂, LEUA)”; “ idem, (1♂, INPA)”; “ idem, 28.vii–18.viii.2001, “M2019” (2♂, IAvH)” (photographed specimen); “ idem, (1♂, LEUA)”; “ idem, (1♂, INPA)”; “ idem, 01–16.xii.2001, “M2754” (1♂, IAvH)”; “ idem, 1–14.vii.2001, “M1928” (1♂, IAvH)” .

Geographical distribution. Bahamas; Brazil; Costa Rica; Cuba; Haiti; Jamaica; Mexico; Nicaragua; Peru; Dominican Republic ( Rodriguez & Rafael 2012); Colombia (new record) ( Fig. 132 ).

Habitat. The specimens were collected with Malaise traps at ground level at the reserve Parque Nacional Natrual Tayrona. This area has mainly thorny bushes and dry tropical forest typical of the Caribbean region of Colombia.

Comments. The analyzed specimens are larger and have the protuberance of the hind trochanter acuter apically compared to the holotype specimen illustrated by Ale-Rocha & Rafael (1995).
