(Figs 127–132)
Diagnosis. Belonging to the assemblage of species with the apical margin of the forewings scalloped, especially on the apical margin of cell M2. Like M. andaquies, it presents a hypandrium V-shaped, apically narrow (Fig. 131) and phallosome with side struts basally separated and medially fused, but unlike this one, it presents an endophallic membrane with abundant spiculae (Fig. 132).
Male. Color. Head (Fig. 129) brown, with scattered brown spots. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Antenna pale brown; maxillary palps brown, Mx 4 darker. Forewing (Fig. 127) dark brown, with pale brown and hyaline spots, cell M1 and M2 with distal hyaline area well marked, pterostigma dark brown, with brown spot that extends outside the margin, while retaining its shape, alar margin dotted, veins pale brown to brown, some dotted. Hindwing (Fig. 128) smoked, with veins brown to pale brown. Legs: coxae and trochanter, femora and tarsi t2–t3 dark brown, femora cream preapically and apically, tibiae and tarsi 1 pale brown, darker apically. Hypandrium with lateral areas dark brown, antero mesal area cream, phallosome dark brown, paraprocts and epiproct pale brown to light brown.
Morphology. As in diagnosis, plus the following: Head (Fig. 129): H/MxW: 1.31; compound eyes large, H/D: 1.75; IO/MxW: 0.55. Vertex V-shaped wide, below upper level of compound eyes. Outer cusp of lacinial tips broad, with four denticles; Mx4/Mx2: 1.5. Forewings (Fig. 127): L/W: 2.35. Pterostigma: lp/wp: 2.42, areola postica wider than tall, apically angled: al/ah: 1.5. Cell m1 and m2 with scalloped posterior margin. Anal vein sinuous and forming part of a fold of the alar membrane, like a pocket. Hindwings (Fig. 128): l/w: 2.60. Hypandrium triangular, with short medial rounded posterior process (Fig. 131), with several setae and macrosetae, apically with four short stout setae. Phallosome (Fig. 132): Side struts basally widened and rounded, meeting at mesal line; arch aedeagal not evident, external parameres widely separated by membrane from endophallus. Paraprocts ovoid (Fig. 130), with short sclerotized apical process directed inward, a dense field of setae and macrosetae on distal area; sensory fields with 26 trichobothria on basal rosettes. Epiproct (Fig. 130) semioval, with rounded and projecting latero-basal processes below the clunium, with setae scattered in the distal field, as illustrated.

Material studied. Holotype male. COLOMBIA. Putumayo, Mocoa, Fin del Mundo natural reserve, Resbalón trail. 1°06’34.50”N: 76°36’41.52”W. 902m. 19–20.v.2015. MUSENUV slide code: 31343. J. Panche. Led light trap in forest canopy.
Etymology. The specific epithet is a noun in apposition, is dedicated to the Inga people, an indigenous ethnic group from the Southwest of Colombia, Putumayo department, where the holotype was found.
