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). Three ocelli, the median reduced, slightly under lateral ones in frontal view (Fig. 13C); lateral ocelli rounded. Frons smooth (Fig. 13C). 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).

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

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); first abdominal sternite prominent, less prominent than in Neometrypus mendoncae n. sp. Supra anal plate posterior margin rounded (Fig. 13E, I).

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

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

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

Female genitalia. Copulatory papilla (Fig. 14E–G), 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); last abdominal tergites dark brown (Fig. 13F). Face medium to light brown with stripes medium brown on the middle and under antennal scapes in frontal view (Fig. 13C); antennal scape medium brown, antennomeres light brown. FWs slightly translucent, medium to light brown; median projection of metanotum ocher, anterior margin whitish (Fig. 13D); abdominal tergites with median band dark brown fading on posterior margin, except on the last three tergites (Fig. 13A, G), last 3–5 abdominal tergites dark brown; sternites dark brown; supra anal plate anterior portion medium brown, posterior portion yellowish-brown (Fig. 13E); subgenital plate dark brown (Fig. 13F); female subgenital plate dark brown (Fig. 13J); cerci light to medium brown; ovipositor apex dark brown (Fig. 13I, J). 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).
