Diagnosis. This species is separated from the other species of Neometrypus by the following characters: general coloration medium brown to reddish-brown, abdominal tergites without median band, sternites medium brown. First abdominal sternite prominent, apex rounded. Male genitalia: anterior margin of pseudepiphallic sclerite Vshaped on median region, posterior margin of LLophi rounded. Female genitalia: copulatory papilla posterior margin somewhat prominent, anterior margin on dorsal face sub-triangular.

Description. General morphology. Head. Fastigium as long as wide, pubescent (Fig. 19A, F). Three ocelli, the median reduced, slightly under lateral ones in frontal view (Fig. 19C); lateral ocelli rounded. Frons smooth (Fig. 19C). Antennal scape longer than wide, inner margin with bristles. Maxillary palpi articles 4 and 5 almost samesized, article 3 slightly shorter; article 5 slightly upcurved (Fig. 19B).

Thorax. DD longer than wide, covered by bristles. DD cephalic margin sub-straight, caudal margin slightly convex (Fig. 19A, F). LL ventro-cephalic angle rounded; ventro-caudal angle gradually ascendant in lateral view (Fig. 19B, G). FWs not surpassing posterior margin of metanotum (Fig. 19A, F).

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, 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 (Fig. 2). Basitarsus dorsal spines 2/1; outer and inner apical spurs same-sized.

Abdomen. Tergites and sternites pubescent (Fig. 19A, B, E); first abdominal sternite prominent, apex rounded (Fig. 19J, K; red arrow). Supra anal plate posterior margin rounded (Fig. 19D).

Male. Anterior margin of median projection of metanotum slightly rounded, posterior margin wider than anterior margin in dorsal view (Fig. 19A). Subgenital plate wider than long, posterior margin convex (Fig. 19E).

Male genitalia (Fig. 20A–D). Pseudepiphallus: pseudepiphallic sclerite almost straight in lateral view, anterior margin V-shaped on median region, lateral region upcurved in lateral view (Fig. 20A–C). LLophi curved inwards, posterior margin rounded in dorsal and ventral views (Fig. 20A, B); inner margin membranous, outer margin sclerotized, thin. PsP almost same-sized as LLophi, posterior margin divided into two lobes, not surpassing posterior margin of pseudepiphallic sclerite in dorsal and ventral views (Fig. 20B); apex of dorsal lobe finger-shaped, slightly curved inwards; apex of ventral lobe pointed, directed inwards (Fig. 20B). r elongate, slightly longer than pseudepiphallic sclerite, flattened laterally (Fig. 20A–C). Ectophallic invagination: EctAp longer than LLophi, straight, inclined to outwards in dorsal and ventral views (Fig. 20A, B); arc not complete, curved posteriorly; ventral projections of ectophallic invagination very short, shorter than arc (Fig. 20B).

Female. Body larger than male (Fig. 19F, G). Subgenital plate wider than long, posterior margin concave on the middle (Fig. 19I). Ovipositor as in fig. 19H, I.

Female genitalia. Copulatory papilla (Fig. 20E–G), as long as wide, somewhat triangular, slightly curved downwards in lateral view; posterior margin somewhat prominent; anterior margin on dorsal face sub-triangular, anterior margin o ventral face straight. Median region on dorsal and ventral faces depigmented.

Coloration. Male and female with similar coloration. Occiput, vertex, pronotum, and abdominal tergites medium brown to reddish-brown (Fig. 19A, B, F, G). Face medium to light brown with stripes grey forming a triangle centrally (Fig. 19C); antennal scape and antennomeres light brown. FWs somewhat translucent, yellowish; median projection of metanotum reddish-brown (Fig. 19A); abdominal tergites sometimes with a dark brown spot on median region of anterior margin, sometimes without spots; sternites medium brown to brownish-orange, supra anal (Fig. 19D, H) and subgenital (Fig. 19E) plates dark brown; female subgenital plate light brown (Fig. 19I); cerci anterior half medium brown, posterior half light brown; ovipositor apex dark brown (Fig. 19A, F). FI and FII yellowish-brown, TI and TII medium brown; FIII yellowish brown to light brown, distal apex medium to dark brown; TIII medium to dark brown, spurs yellowish with basis medium to dark brown; tarsomeres yellowish-brown.
