Figs 1F View Figure 1 , 6A-H View Figure 6
Length.
♂♂ 9.2-9.6 mm (n = 3). Head (Figs 1F View Figure 1 , 6A View Figure 6 ): in dorsal view, well produced anteriorly; median length of crown approximately 8/10 of interocular width and 5/10 of transocular width; anterior margin rounded; ocelli large, located approximately on imaginary line between anterior eye angles; surface of crown slightly concave; antennal ledge, in dorsal view, not protuberant. Thorax (Figs 1F View Figure 1 , 6A View Figure 6 ) with pronotum, in dorsal view, with width slightly greater than transocular width of head. Forewing with base of fourth apical cell approximately aligned with base of third.
Coloration (Fig. 1F View Figure 1 ).
Head, pronotum, and mesonotum pale yellow. Forewing translucent with transverse broad orange stripe across bases of apical cells.
Male terminalia.
Pygofer (Fig. 6B View Figure 6 ), in lateral view, with posterior margin rounded; macrosetae distributed mostly on posterior half but some located more anteriorly. Subgenital plate (Fig. 6C View Figure 6 ), in ventral view, with basal half broad and distal half very narrow; with elongate uniseriate macrosetae on basal half, microsetae distributed along outer lateral margin. Connective (Fig. 6D View Figure 6 ), in dorsal view, T-shaped; stalk not carinate dorsally, subequal in length to one arm width. Style (Fig. 6D View Figure 6 ), in dorsal view, slender, elongate, extending posteriorly beyond apex of connective; narrowed apically, apex obtuse. Aedeagus symmetrical (Fig. 6E, F View Figure 6 ); shaft short; in lateral view, somewhat sinuous; with pair of ventral, preapical sclerotized dentiform processes; dorsal margin dentate; gonoduct distinct, its apical portion slightly curved dorsally, gonopore located apically. Membrane connecting aedeagus to paraphyses with posterior sclerotized rugose lobe located close to aedeagal processes. Paraphyses slightly asymmetrical; elongate, extending well beyond subgenital plate apex; stalk shorter than rami; in dorsal view (Fig. 6G View Figure 6 ), stalk slender, rami divergent apically; in lateral view (Fig. 6H View Figure 6 ), stalk slightly arched dorsally, each ramus with dorsal lobe at midlength and acute apex.
Female unknown.

Taxonomic notes.
According to Young (1977), the body of D. mendica (Fig. 1F View Figure 1 ) is slenderer and more delicate than that of D. pauperata (Fig. 1H View Figure 1 ). Dasmeusa mendica can be distinguished from D. pauperata , as well as from the remaining known species of the genus, by the short and somewhat sinuous aedeagus, bearing a pair of ventral, preapical sclerotized dentiform processes (Fig. 6E, F View Figure 6 ).
