Internal sternite VIII membranous. Pygofer ( Figs 49 View FIGURES 49 , 50) with short macrosetae, except on anterodorsal portion; ventral margin broadly rounded; apex truncated. Ovipositor (Fig. 50) slender, curved dorsad, not surpassing pygofer apex. First valvifer (Fig. 51) trapezoid, 1.3 times higher than long; anterior and dorsal approximately straight; posteroventral angle rounded. First valvula (Fig. 51) with dorsal and ventral margins, almost parallel, slightly convergent apically, ca. 9 times longer than high; ventral interlocking device long, extending over basal two-third; dorsal sculpturing area areolate on apical twothirds; apical portion (Fig. 52) with ventral sculpture present only near apex, continuous with the dorsal sculpture, apex tapered and acute. Second valvula (Fig. 53) ca. 16 times longer than high; dorsal and ventral margins parallel; dorsal margin with two subapical teeth widely spaced (second subapical tooth inconspicuous); apical portion (Fig. 54) with rounded denticles between second subapical tooth and apex, and scattered denticles anterior to second subapical tooth; apex rounded, with denticles on ventral margin. Second valvifer (Fig. 55) ca. 2.7 times higher than long. Gonoplac (Fig. 55) 5 times longer than high; dorsoapical margin long, almost parallel to ventral margin; ventral margin (Fig. 56) broadly rounded, with spaced macrosetae near ventral margin; apex rounded.

Etymology. The specific epithet, albohabena, is composed by the Latin words “ albo ˮ and “ habena ˮ which refers to the forewing with a transverse white stripe.

Notes. M. albohabena sp. nov. will key out at couplet 3 in Blocker’s (1979) key and resembles M. clarkei Blocker, 1979 from Colombia, in having the style with two long and curved processes. However, in M. clarkei the processes arise near the apex, before a curved and expanded portion of the apical fourth, while in the new species, the style in not expanded apically and the dorsal process arises at mid-length of style.
