Male: COLOMBIA, Boyacá, SFF[Santuario de Fauna y Flora] Iguaque, El Níspero, Malaise, 0538’N/7331’W, 2730 m [eters], 13–18.xii.2001, P. Reina leg “M2476 (1 ♂, IAvH) (photographed specimen). PARATYPES. idem 17–21.xii.2001, “M2581 (1 ♂, LEUA); idem “M2476 (1 ♀, IAvH); idem Qda.[Quebrada] Los Mudos, 0544’N/7326’W, 27.ii–17.iii.2003, “M3563 (1 ♀, LEUA) (photographed specimen). Holotype with left wing mounted on microslide with Canada balsam. Left antenna and terminalia placed in a microvial with glycerin, both pinned along with the specimen. Etymology. From the Latin gracilis (= thin), the name refers to the shape of the ejaculatory ducts of the phallus in the male genitalia. Geographical distribution. Colombia (Boyacá) (Fig. 107). Habitat. The specimens were collected in the Santuario de Fauna y Flora Iguaque reserve, where the vegetation is composed of cloud Andean forests of the cordillera of the Northeast region of Colombia. Taxonomic notes. Based on males and due to the shape of the phallic guide and phallus, C. gracilis sp. nov. is similar in appearance to C. nigrifrons Rafael, 1990 [see figure 109 presented by Rafael (1990)]. It differs from C. nigrifrons by having the surstyli with outer and inner margins sinuous, with tips inward-directed (Fig. 40) [versus surstyli with outer and inner margins straight in C. nigrifrons, figure 107 presented by Rafael (1990)]; right surstylus with dorsal lobe and distinct apical lobe when seen in lateral view (Figs 41–42) [versus right surstylus with margins straight when seen in lateral view, figure 108 presented by Rafael (1990)]; ejaculatory apodeme mushroom-shaped, with margins sinuous (Fig. 45) [versus ejaculatory apodeme narrowed, figure 110 presented by Rafael (1990)].
