( Figs 1E, F View FIGURE 1 ; 9 View FIGURE 9 ; 10 View FIGURE 10 ; 23 View FIGURE 23 ; Table 4 View TABLE 4 )

Etymology. Species named after Márcia Couri, dipterist (specialist in Muscidae ), and professor at the Departamento de Entomologia (Entomology Department) of the Museu Nacional – UFRJ.

Type locality. Brazil, Pará, Belterra .

Type material. Holotype male. Fazenda Treviso / Brasil, PA[rá], Belterra / 3°8’58.26”S // 54°50’4.14”W / 30.XI- 11XII.2018 / Souza-Dias, P.G.B.; Redu, D.R.; Campos L.D. leg. | LDC_200; MZSP GoogleMaps Allotype female.

Diagnosis. This species is separated from the other species of Neometrypus by the following characters: FWs absent. Male: median projection of metanotum absent. Male genitalia: PsP flattened dorso-ventrally in posterior view, posterior margin not divided into two lobes; EctAp longer than LLophi, straight, inclined to outwards in dorsal and ventral views. Female genitalia: dorsal and ventral faces of copulatory papilla with a median split.

Description. General morphology. Head. Fastigium as long as wide, pubescent ( Fig. 9A, F View FIGURE 9 ). Three ocelli, the median reduced, under lateral ones in frontal view ( Fig. 9C View FIGURE 9 ); lateral ocelli rounded. Frons smooth ( Fig. 9C View FIGURE 9 ). Antennal scape longer than wide, inner margin with bristles. Maxillary palpi articles 3, 4, and 5 almost same-sized; article 5 upcurved ( Fig. 9B, G View FIGURE 9 ).

Thorax. DD longer than wide, covered by bristles. DD cephalic margin straight, caudal margin slightly convex ( Fig. 9A, F View FIGURE 9 ). LL ventro-cephalic angle rounded; ventro-caudal angle gradually ascendant in lateral view ( Fig. 9B, G View FIGURE 9 ). FWs absent ( Fig. 9A, F View FIGURE 9 ).

Legs. TI with three apical spurs, two ventral, one dorsal. TII with three apical spurs, two ventral and one dorsal. TIII subapical spurs with two spines between each spur, ten or more spines above subapical spurs on inner and outer sides. TIII inner apical spurs: iad>iam>iav; outer apical spurs: oam>oav>oad, oav and oad almost same-sized. Basitarsus dorsal spines 3/1; outer and inner apical spurs same-sized

Abdomen.Tergites and sternites pubescent ( Fig. 9A,F, E View FIGURE 9 ). Supra anal plate posterior margin rounded ( Fig.9D, H View FIGURE 9 ).

Male. Median projection of metanotum absent. Subgenital plate as long as wide, posterior margin straight ( Fig. 9E View FIGURE 9 ).

Male genitalia ( Fig. 10A–D View FIGURE 10 ). Pseudepiphallus: pseudepiphallic sclerite straight in lateral view, anterior margin straight on median region, lateral region upcurved in lateral view ( Fig. 10A–C View FIGURE 10 ). LLophi slightly curved inwards, posterior margin truncated in dorsal and ventral views; inner margin membranous, outer margin sclerotized, thin ( Fig. 10A, B View FIGURE 10 ). PsP shorter than LLophi, flattened dorso-ventrally in posterior view ( Fig. 10B, D View FIGURE 10 ); posterior margin not divided into two lobes, not surpassing posterior margin of pseudepiphallic sclerite in dorsal and ventral views ( Fig. 10B View FIGURE 10 ). r elongate, longer than pseudepiphallic sclerite, flattened laterally ( Fig. 10A–C View FIGURE 10 ). Ectophallic invagination: EctAp longer than LLophi, straight, inclined to outwards in dorsal and ventral views ( Fig. 10A View FIGURE 10 ); arc not complete, curved posteriorly; ventral projections of ectophallic invagination very short, shorter than arc ( Fig. 10B View FIGURE 10 ).

Female. Body larger than male ( Fig. 9F, G View FIGURE 9 ). Subgenital plate wider than long, posterior margin concave on the middle ( Fig. 9I View FIGURE 9 ). Ovipositor as in fig. 9H, I.

Female genitalia. Copulatory papilla ( Fig. 10E–G View FIGURE 10 ), triangular in dorsal and ventral views, straight in lateral view; posterior margin truncated; dorsal and ventral faces with a median split.

Coloration. Male and female with similar coloration. Occiput, vertex, and pronotum reddish-brown; abdominal tergites medium brown to reddish-brown ( Fig. 9A, B, F, G View FIGURE 9 ). Face medium brown to yellowish-brown ( Fig. 9C View FIGURE 9 ); antennal scape and antennomeres medium brown; abdominal tergites reddish-brown getting lighter posteriorly; sternites yellowish-brown, supra anal plate light to medium brown ( Fig. 9D, H View FIGURE 9 ), subgenital plate yellowish-brown ( Fig. 9E View FIGURE 9 ); female subgenital plate light brown ( Fig. 9I View FIGURE 9 ); ovipositor apex yellowish-brown; cerci medium brown ( Fig. 9H View FIGURE 9 ). FI and FII yellowish-brown, TI and TII medium brown; FIII yellowish-brown, distal apex slightly darker; TIII medium brown, spurs medium brown with apex dark brown; tarsomeres yellowish-brown.
