Additionally, it differs in lacking the distinctive apicolateral projections from the apex of the dorsal phallic spine that characterize the other two species. Adult —Length of forewing: male 3.1 mm . Forewing with forks I, II, and III present, hind wing with forks II and III. Spur formula 0:4:4. Overall color (in alcohol) yellowish brown. Wing bar not evident Male genitalia —Ventral process of segment VI laterally compressed, ventrally projecting, large, subtriangular, length about equal to width at base, process not retracted anterobasally. Segment IX nearly evenly rounded anterolaterally, length greatest midlaterally, posterolateral margin weakly rounded, narrowing ventrally; segment deeply mesally excised dorsally and ventrally, forming lateral lobes, separated dorsomesally by much less than ½ width of segment. Tergum X short, lateral margins subparallel, apical margin concave, apicolateral lobes very weakly projecting; apicomesal lobes visible in lateral view, broadly rounded apically; ventrolateral lobes distinct, irregular, projecting. Inferior appendages with short tapering dorsolateral projections, apicoventral projections paired, very elongate, narrow, acute apically. Mesal pockets of inferior appendage with apical processes short, posterodorsally curved. Paramere appendage short (much shorter than dorsal phallic spine), dorsally curved, apex acute. Dorsal phallic spine, as viewed laterally, with apex strongly upturned and acute, ventral margin extended as rounded expansion; spine, in dorsal view, very slightly widened in middle, apex acute. Phallicata with dorsal margin somewhat elevated and sclerotized (to accommodate ventral margin of dorsal phallic spine), ventrally with pair of small rounded, sclerotized basal projections; endophallic membrane with pair of elongate, apically acute spines (possibly phallotremal complex); ventromesal spine absent. Holotype male (alcohol)— PERU : Huanuco : Tingo Maria , premontane rain forest, 672 m , 1- 6.ii.1980 , JB Heppner ( UMSP000097160 ) ( MJP ). Paratypes — PERU : Huanuco : same data as holotype – 1 male (alcohol) ( NMNH ). Etymology —This species is named M. prolata , from the Latin prolatus (to carry forward), used in the sense of being extended or elongate, and referring specifically to the very elongate apicoventral projections of the inferior appendages in this species.
