Diagnosis. This species is separated from the other species of Neometrypus   by the following characters: abdominal tergites with median band dark brown fading on posterior margin, except on the last three tergites, last 3–5 abdominal tergites dark brown; first abdominal sternite prominent, less prominent than in Neometrypus mendoncae   n. sp.; basitarsus dorsal spines 3/2. Male genitalia: PsP longer than LLophi, posterior margin divided into two lobes same sized. Female genitalia: copulatory papilla triangular, straight in lateral view; anterior margin on dorsal face concave, anterior margin o ventral face convex.

Description. General morphology. Head. Fastigium as long as wide, pubescent ( Fig. 13A, G View FIGURE 13 ). Three ocelli, the median reduced, slightly under lateral ones in frontal view ( Fig. 13C View FIGURE 13 ); lateral ocelli rounded. Frons smooth ( Fig. 13C View FIGURE 13 ). Antennal scape longer than wide, inner margin with bristles. Maxillary palpi articles 4 and 5 almost samesized, article 3 longer; article 5 upcurved ( Fig. 13B, H View FIGURE 13 ).

Thorax. DD longer than wide, covered by bristles. DD cephalic margin sub-straight, caudal margin slightly convex ( Fig. 13A, G View FIGURE 13 ). LL ventro-cephalic angle rounded; ventro-caudal angle gradually ascendant in lateral view ( Fig. 13B, H View FIGURE 13 ). FWs not surpassing posterior margin of metanotum ( Fig. 13A, G View FIGURE 13 ).

Legs. TI with three apical spurs, two ventral, one dorsal. TII with four apical spurs, two ventral and two dorsal. TIII subapical spurs with two spines between each spur (rarely one), eight or nine 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 3/2 (rarely 3/1); outer and inner apical spurs same-sized.

Abdomen. Tergites and sternites pubescent ( Fig. 13A, F, G View FIGURE 13 ); first abdominal sternite prominent, less prominent than in Neometrypus mendoncae   n. sp. Supra anal plate posterior margin rounded ( Fig. 13E, I View FIGURE 13 ).

Male. Anterior margin of median projection of metanotum rounded, posterior margin slightly wider than anterior margin in dorsal view ( Fig. 13D View FIGURE 13 ). Subgenital plate as long as wide, posterior margin convex ( Fig. 13F View FIGURE 13 ).

Male genitalia ( Fig. 14A–D View FIGURE 14 ). Pseudepiphallus: pseudepiphallic sclerite slightly upcurved in lateral view, anterior margin concave on median region, lateral region upcurved in lateral view ( Fig. 14A–C View FIGURE 14 ). LLophi curved inwards; posterior margin rounded in dorsal and ventral views; inner margin membranous, outer margin sclerotized, thin ( Fig. 14A, B View FIGURE 14 ). PsP longer than LLophi, posterior margin divided into two lobes, same-sized, not surpassing posterior margin of pseudepiphallic sclerite in dorsal and ventral views ( Fig. 14B View FIGURE 14 ); apex of dorsal and ventral lobes fingershaped, inclined inwards. r elongate, as long as pseudepiphallic sclerite, flattened laterally, apex bifid ( Fig. 14A–C View FIGURE 14 ). Ectophallic invagination: EctAp longer than LLophi, slightly curved inwards, inclined to outwards in dorsal and ventral views ( Fig. 14A View FIGURE 14 ); arc not complete, curved posteriorly; ventral projections of ectophallic invagination very short, shorter than arc ( Fig. 14B View FIGURE 14 ).

Female. Body larger than male ( Fig. 13G, H View FIGURE 13 ). Subgenital plate wider than long, posterior margin slightly concave on the middle ( Fig. 13J View FIGURE 13 ). Ovipositor as in fig. 13I, J.

Female genitalia. Copulatory papilla ( Fig. 14E–G View FIGURE 14 ), triangular, straight in lateral view; posterior margin somewhat rounded; anterior margin on dorsal face concave, anterior margin of ventral face convex, longer than anterior margin of dorsal face. Posterior margin depigmented.

Coloration. Male and female with similar coloration. Occiput, vertex, pronotum, and abdominal tergites reddish-brown ( Fig. 13A, G View FIGURE 13 ); last abdominal tergites dark brown ( Fig. 13F View FIGURE 13 ). Face medium to light brown with stripes medium brown on the middle and under antennal scapes in frontal view ( Fig. 13C View FIGURE 13 ); antennal scape medium brown, antennomeres light brown. FWs slightly translucent, medium to light brown; median projection of metanotum ocher, anterior margin whitish ( Fig. 13D View FIGURE 13 ); abdominal tergites with median band dark brown fading on posterior margin, except on the last three tergites ( Fig. 13A, G View FIGURE 13 ), last 3–5 abdominal tergites dark brown; sternites dark brown; supra anal plate anterior portion medium brown, posterior portion yellowish-brown ( Fig. 13E View FIGURE 13 ); subgenital plate dark brown ( Fig. 13F View FIGURE 13 ); female subgenital plate dark brown ( Fig. 13J View FIGURE 13 ); cerci light to medium brown; ovipositor apex dark brown ( Fig. 13I, J View FIGURE 13 ). FI, FII, TI, and TII yellowish-brown, medium brown spotted; FIII yellowish-brown, slightly medium brown striped, distal apex slightly darker; TIII light brown, dark brown spotted on the base of subapical spurs; spurs light brown with apex medium brown; tarsomeres light brown ( Fig. 13B, H View FIGURE 13 ).
