Holotype male</b> (Fig. 17A). Body length: 9.5 mm; wing length: 6.4 mm. Similar to <i>M. caipora</i> <b>sp. nov.</b> except as noted: <b>Thorax</b> (Fig. 17A, B). Scutum covered with more dense short black setae, slightly longer at posterior 1/2; 2–3 black postsutural dorsocentral macrosetae; 2 black postalar macrosetae. <b>Leg I.</b> Anterior surface of coxa I with slender white macrosetae. Femur almost wholly covered with short white setae, with 4–5 long white setae at ventral ½ (Fig. 17C). Tibia with ventral to anteroventral row of 4 white macrosetae from basal 2/3 to apex. Basitarsus with 1 posteroventral white macroseta near base. <b>Leg II.</b> Femur wholly covered with white setae. Tibia with posteroventral row of 3–4 short white setae, 1 ventral and 1 posteroventral white setae at apical 1/2; 2–3 dorsal short white setae at apical 1/3. Basitarsus with 1–2 posteroventral white setae. <b>Leg III.</b> Femur wholly covered with white setae, except for 1 antero- and 1 posterodorsal and 1 posterior preapical black seta. Tibia with 2 anterodorsal and 2 anteroventral white setae at apical 1/2. <b>Wing</b> (Fig. 17E). Cell <i>cua</i> closed and petiolate with petiole as long as crossvein <i>r-m</i>. <b>Abdomen.</b> Tergite 8 with wide concavity at anterior margin, with rounded posterior corners, with a few black macrosetae (Fig. 18H). Sternite 8 subrectangular, covered with a few short setae at posterior edge (Fig. 18I). <b>Terminalia</b> (Fig. 18). Orangish brown to dark brown. Inner dorsal process of epandrium longer and digitiform (Fig. 18C). Hypandrium somewhat saddle-shaped, only with posterolateral macrosetae at posterior edge (Fig. 18K). Gonocoxite subtriangular, dorsal edge truncated, membranous at apex; outer edge covered with short black setae; ventral edge with black macrosetae (Fig. 18E, F). Gonostylus 1.5 times longer than gonocoxite, mostly subrectangular, weakly sclerotized at middle and apex; apex rounded, slightly curved dorsally, covered with spicules (Fig. 18J).</p><p><b>Variation.</b> Body length: 8.75–11 mm, wing length: 6.8–7.5 mm (n = 11).</p><p><b>Female.</b> Similar to male, except as noted: body length: 9.3–12.2 mm, wing length: 6.6–8.2 mm (n = 8).
