Tomosvaryella galapagensis Aczél, 1948: 25 ; 1952: 248; Hardy, 1965b: 64; Ale-Rocha, 1992b: 351, figs 1–8; Ale-Rocha, 1996: 172; Ale-Rocha & Souza 2011: 297, figs 13, 55–57; Rodriguez & Rafael 2012: 30, 33.

Diagnosis. Male. Postcranium brown, dorsally pruinose, ventrally grayish-pruinose ( Fig. 1 ). Hind trochanter with yellow-setose protuberance ( Fig. 2 ). Tergites and sternites 6 and 7 as in Fig. 3 . Surstyli similar in shape, with hooked-tip, having dorso-basal protuberance, right surstylus slightly shorter ( Figs 4–5 ), both surstyli with tips downward-directed, mainly the left one ( Figs 6–7 ). Phallic guide with apex simple, angled at about 45 degrees ( Fig. 8 ). Phallus with one ejaculatory duct with two spines, one duct with a single spine and one duct without spine. Ejaculatory apodeme somewhat sandal-shaped, darker near base, rounded on both ends ( Fig. 9 ). Gonopods subsymmetrical ( Fig. 10 ).

Material examined. COLOMBIA: Boyacá, SFF[Santuario de Fauna y Flora] Iguaque, Cabaña Chaina , 5º25’N – 73º27’W, 2600 m [eters], Malaise, 31.viii.–16.ix.2001, A. Roberto, “M2066” (1♂, LEUA) (photographed specimen); “ idem, 01–14.feb[ii].2001”, “M1271” (1♂, IAvH).

Geographical distribution. Ecuador, Galapagos islands; Mexico, Baja California ( Rodriguez & Rafael 2012); Colombia (new record) ( Fig. 132 ).

Habitat. The specimens were collected with Malaise trap at the ground level at the Santuario de Fauna y Flora Iguaque reserve, where the vegetation is composed of forest typical of the mountain range of the Northeast region of Colombia.

Comments. Specimens collected are similar to the holotype illustrated by Ale-Rocha (1992), differing only by the left surstylus, which has the apex more truncated when examined in lateral view.
