Diagnosis. This species is separated from the other species of Neometrypus by the following characters: median projection of metanotum almost triangular, yellow; abdominal tergites with median stripes dark brown, lateral bands dark brown. Male genitalia: EctAp very short, shorter than PsP.

Description. General morphology. Head. Fastigium as long as wide, slightly pubescent (Fig. 21A, G). Two lateral ocelli rounded, median ocellus absent (Fig. 21C). Frons smooth (Fig. 21C). Antennal scape longer than wide, inner margin with bristles. Maxillary palpi articles 4 and 5 almost same-sized, article 3 the longest (Fig. 21B).

Thorax. DD longer than wide, covered by bristles. DD cephalic margin straight, caudal margin slightly convex (Fig. 21A, G). LL ventro-cephalic angle rounded; ventro-caudal angle gradually ascendant in lateral view (Fig. 21B, H). FWs surpassing posterior margin of metanotum (Fig. 21A, G).

Legs. TI with three apical spurs, two ventral, one dorsal. TII with three apical spurs, two ventral, one dorsal.

TIII subapical spurs with two spines between each spur (rarely one), six or eight 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 2/1; outer and inner apical spurs same-sized.

Abdomen. Tergites pubescent (Fig. 21A, G); first abdominal sternite not prominent. Supra anal plate posterior margin rounded (Fig. 21E, I).

Male. Anterior margin of median projection of metanotum slightly rounded, posterior margin slightly wider than anterior margin in dorsal view (Fig. 21D). Subgenital plate as long as wide, posterior margin convex (Fig. 21F).

Male genitalia (Fig. 22A–D). Pseudepiphallus: pseudepiphallic sclerite almost straight in lateral view, anterior margin somewhat concave, lateral region upcurved in lateral view (Fig 22A–C). LLophi straight, posterior margin rounded in dorsal and ventral views (Fig. 22A, B); inner margin membranous, outer margin sclerotized, thin. PsP same-sized as LLophi, posterior margin divided into two lobes, dorsal lobe slightly longer than ventral lobe, not surpassing posterior margin of pseudepiphallic sclerite in dorsal and ventral views (Fig. 22A, B); apex of dorsal and ventral lobes finger-shaped, inclined inwards (Fig. 22B). r thin, elongate, as long as pseudepiphallic sclerite, flattened laterally, apex single (Fig. 22A–C). Ectophallic invagination: EctAp very short, shorter than PsP, inclined to outwards in dorsal and ventral views; arc not complete, curved posteriorly; ventral projections of ectophallic invagination very short, shorter than arc (Fig. 22B).

Female. Body larger than male (Fig. 21G, H). Subgenital plate wider than long, posterior margin concave on the middle (Fig. 21J). Ovipositor as in fig. 21I, J.

Female genitalia. Copulatory papilla (Fig. 22E–F), cylindrical, somewhat curved downwards in lateral view; posterior margin rounded; anterior margin convex on dorsal face, anterior margin slightly concave on ventral face, shorter than anterior margin of dorsal face. Median region of posterior margin depigmented.

Coloration. Male and female with similar coloration. Occiput, vertex, and pronotum yellowish-brown, abdominal tergites dark yellow (Fig. 21A, G). Face yellowish-brown to light brown with stripes medium to dark brown under antennal scapes in frontal view (Fig. 21C); antennal scape yellowish-brown, antennomeres light brown with a single antennomere medium brown every ten antennomeres. FWs slightly translucent, medium to light brown; median projection of metanotum dark yellow (Fig. 21D); abdominal tergites with median stripes dark brown, lateral bands dark brown (Fig. 21B, H); sternites whitish (Fig. 21F); supra anal plate anterior margin medium to dark brown, posterior portion pale yellow (Fig. 21E); subgenital plate dark brown (Fig. 21F); female subgenital plate light brown (Fig. 21J); cerci yellowish-brown; ovipositor apex dark yellow (Fig. 21I, J). FI, FII, TI, and TII light brown, medium brown spotted; FIII yellowish-brown, slightly medium brown striped; TIII medium to dark brown; spurs light brown with apex and base medium brown; tarsomeres light brown (Fig. 21B, H).
