Paratypes: same data, 2♂ [pinned], 6.ii.2017, leg. W. Mey (MfN) .

Etymology. The specific name is derived from Bogotá.

Description. Male (Fig. 15F). Length of each forewing 9 mm, wing span 19–20 mm. Head brown, frons and vertex densely covered by grey-white hairs; maxillary and labial palpi dark brown, scapes bulbous, with grey-white hairs, antennae nearly twice as long as forewings, dark brown, white-ringed at articulations of flagellomeres, eyes small, widely separated middorsally; forewings with brown veins and grey-white hairs on wing membrane, large brown spot on bifurcation of cubitus and crossvein cu-a; hindwings white, Cu1a+1b seemingly running onto M3+4, Cu2 and A1 with short, basal stalk, jugum and jugal margins of hindwings with long, thin hairs. Forelegs brown, middle and hind legs yellow-brown, tarsal spines black, spurs 2.4.4. Abdomen grey-brown.

Male genitalia (Figs 12 A–12D): Segment IX in lateral view vertical anteriorly, separated on lateral side into tergum and sternum by broad, pleural sclerite; tergum X straight and membranous dorsally, apicolateral sides sclerotized and folded medioventrad, lateral hooks absent; preanal appendages triangular, somewhat twisted in basal half, nearly as long as tergum X; inferior appendages elongate, each with apical segment small; phallic apparatus with short and slightly curved phallotheca, phallotremal sclerite spatulate in lateral view, U-shaped in ventral view.

Female: unknown

Diagnosis. The new species shares with M. lateralis Flint 1983 the sclerotized, apicolateral sides of tergum X and the straight inferior appendages. However, preanal appendages and phallic apparatus are of different morphology. Also, the small eyes of the male exclude the species from a closer relationship with M. lateralis, where eyes meet mid-dorsally. Similar genitalia and small eyes are present in M. microps Flint 1991 which was described from Choco and Antioquia, but it does not exhibit triangular preanal appendages, a character which is present in another Colombian species, M. modesta Banks 1913 . The phallic apparatus of the latter species is strongly bent basally and much longer than in the new species.
