Diagnosis.

Thorax light brown, scutum with a pair of dark slender dorsocentral stripes. Vein CuA with gentle distal curve, CuP short, ending around mid of CuA. Syngonocoxite not extending to distal margin of terminalia; gonocoxites without an inner dorsal projection, inner apical projections small, slender, acute. Gonostylus ventral branch digitiform, dorsal branch short, pointed.

Description.

Male (Fig. 2B). Body length, 5.2 mm. Head (Fig. 3B). Width, 0.54mm, height, 0.49mm. Vertex brown, with abundant brownish short setae. Three ocelli, mid ocellus smaller; lateral ocelli separated from eye margin by less than their diameter. Occiput brown. Ommatotrichia abundant, short, yellowish. Scape and pedicel brownish yellow, cylindrical, scape longer than pedicel, both with small brownish-yellow setae; 14 flagellomeres, mostly light brown, with scattered dark small setae; first flagellomere almost twice as long as second. Frons and clypeus light brown, subrectangular, covered with dark setae; palpus with five light brown palpomeres, lighter towards apex, last palpomere about twice as long as fourth. Thorax (Figs 3E, H). Scutum light brown, with a pair of dark brown dorsocentral stripes and a weak medial dark stripe, all three connected at posterior margin of scutum, a pair of dark brown lateral longitudinal stripes above wings. A row of stronger setae above wing and a single row of differentiated dorsocentrals. Scutellum dark brown, with a lateral pair of scutellars on each side and three medial setae on posterior margin. Pleural sclerites dark brown, with some light areas on dorsal half of katepisternum and at dorsal end of mesepisternum. Pleural membrane yellowish brown. Antepronotum with nine long setae, proepisternum with four setae. Proepimeron, anepisternum, katepisternum, mesepimeron, and metepisternum bare. Laterotergite with 18 long dark setae, mediotergite with a row of dark setae on ventral half. Halter pedicel yellowish, knob light brown, both setose. Legs. Coxae and femora yellowish brown, tibiae and tarsi light brown. Foreleg tibiae with ventral oval depression with abundant irregular trichia; first tarsomere about 1.5 times as long as tibiae. Tibiae and tarsi with erect, short, dark setae along their entire length. Tibial spurs 1:2:2, brown, slightly longer than tibia width at apex. Tarsal claws with a large apical tooth and a smaller basal one. Wing (Fig. 4B). Length 4.0 mm, width 1.8 mm. Membrane light brown, densely covered with decumbent macrotrichia on all cells, veins brownish. Sc complete, setose ventrally, reaching C well beyond base of Rs, almost at mid length of wing; sc-r present, bare, placed basal to middle of Sc. C ending at apex of R5. R1 long, reaching C beyond distal fifth of wing. First sector of Rs oblique, setose ventrally, slightly longer than r-m. R5 sinuous, reaching C at wing apex, r-m bare, oblique. M1+2 stem shorter than medial fork. M1 weak, obsolete basally. M4 complete. CuA complete, gently curving on distal third. CuP short, reaching around level of mid CuA. Abdomen. Segments chestnut brown, cylindrical, slender, with long brownish setae on tergites and sternites. Sternite 8 not projecting posteriorly beyond basal half of gonocoxite. Tergite 8 well developed, with short medial projection covering less than basal half of tergite 9, almost rectangular, occupying anterior fourth of terminalia. Terminalia (Figs 5 D–F, 6C, D). Light brown. Longer than wide. Gonocoxite ventral surface almost fused medially, forming a syngonocoxite with a deep ventral medial cleft, extending close to half the level of gonocoxite. Gonocoxites elongate, with a short inner dorsal projection, apically truncated, and a slender, dorsal-apical projection. Gonocoxal apodem conspicuous, with acute apex. Dorsal branch of gonostylus wider, tapering towards apex, ventral branch digitiform, with scattered setae; parameres curved, approaching each other medially and then diverging, slightly projecting beyond apex of gonocoxites. Aedeagus very short, not reaching apex of cerci. Cerci typically slender, digitiform, with abundant short strong setae, not projecting beyond distal margin of gonocoxites.

Female. Unknown.

Etymology.

The specific epithet colombiana (nominative, adjective feminine) of this species refers to Colombia, the country in which the type materials were collected.
