Diagnosis. Male. Antenna with scape and pedicel brown, postpedicel dark brown, slightly acute. Frontal triangle with conspicuous dark brown callus. Coxae dark brown, trochanters light brown, tibiae dark brown, with bases and apices light brown. Abdomen ground color dark brown, tergite 1 sparsely velvety light brown pruinose, with four brown and long setae laterally; tergites 2–5 velvety dark brown anteriorly, brown pruinose posteriorly and laterally, with conspicuous setae. Surstyli subsymmetrical, slightly subequal to epandrium length, completely setose; thickened at base, thin apically, with tips slightly inward directed. Apex of phallic guide stout, long, thickened at base, acute apically. Phallus trifid, with ducts distinctly separated only in distal 1/3, only tips of ejaculatory ducts slightly coiled. Ejaculatory apodeme funnel-shaped, with sinuous margins.

Surstyli ( Figs 56–58 ) subsymmetrical, slightly equal to epandrium length, completely setose; thickened at base, thin apically, with tips slightly inward-directed, left surstylus slightly shorter than right ( Fig. 56 ); both surstyli with margins straight, tips forward directed when seen in lateral view ( Figs 57–58 ). Gonopods subsymmetrical, right gonopod slightly thicker than left ( Fig. 59 ). Apex of phallic guide stout, long, thickened at base, acute apically ( Fig. 60 ). Ejaculatory apodeme funnel-shaped, with sinuous margins ( Fig. 61 ). Phallus trifid, with ducts distinctly separated only in distal 1/3, only tips slightly coiled ( Fig. 60 ). FEMALE. Unknown.

Type material. HOLOTYPE. Male: COLOMBIA, Caquetá, Vereda Las Brisas, 0145’14’’N/7544’51.5’’W, 2040 m [eters], 09–23. Nov [xi].2016, (1 ♂ LEUA –8677) (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. The new species is named after Klinsmann Steeven Ramos Vargas, the son of the first author. Specific epithet in genitive case.

Geographical distribution. Colombia (Caquetá) ( Fig. 107 ).

Habitat. The specimens were collected in the cloudy forest of the eastern cordillera in the Colombian Andean Amazon region.

Taxonomic notes. Cephalops klinsmanni sp. nov. runs to C. villifemoralis Hardy, 1954 in the couplet 14 of the key presented by Rafael (1990). It differs from C. villifemoralis in having postpedicel dark brown (versus postpedicel yellow in C. villifemoralis ); all coxae dark brown ( Fig. 49 ) (versus hind coxa light brown); both surstyli thickened at the base, thin apically, with tips slightly inward directed, left surstylus slightly shorter than right ( Fig. 56 ) [versus both surstyli conical-shaped, with tips downward directed, left surstylus clearly shorter and thinner than right, figure 56 presented by Rafael (1990)]; ejaculatory apodeme funnel-shaped, with sinuous margins ( Fig. 61 ) [versus ejaculatory apodeme T-shaped, with margins somewhat straight, figure 58 presented by Rafael (1990)]; phallus trifid, with ducts distinctly separated only in distal 1/3, with tips of ejaculatory ducts slightly coiled ( Fig. 60 ) [versus phallus trifid, with ducts completely separated, with tips of ejaculatory ducts no coiled, figure 57 presented by Rafael (1990)].
