Diagnosis. This species is separated from the other species of Neometrypus by the following characters: face with stripes medium brown surrounding antennal scapes in frontal view; abdominal tergites with a median band dark brown, medium brown spotted laterally; supra anal plate posterior margin straight, anterior portion dark brown, posterior portion light brown. Male: anterior margin of median projection of metanotum rounded posterior margin wider than anterior margin in dorsal view. Female genitalia: ventral face of copulatory papilla two times longer than dorsal face; ventral face with a median slit

Description. General morphology. Head. Fastigium as long as wide, pubescent (Fig. 7A, G). Three ocelli, the median reduced, slightly under lateral ones in frontal view (Fig. 7C), frons smooth (Fig. 7C). Antennal scape longer than wide, inner margin with bristles. Maxillary palpi articles 3 and 5 almost same-sized, article 4 slightly shorter; article 5 slightly upcurved (Fig. 7B, H).

Thorax. DD longer than wide, covered by bristles. DD cephalic margin slightly concave, caudal margin straight (Fig. 7A, G). LL ventro-cephalic angle rounded; ventro-caudal angle gradually ascendant in lateral view (Fig. 7B, H). FWs surpassing posterior margin of metanotum (Fig. 7A, 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 (sometimes one) spines between each spur, 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 2 /1; outer and inner apical spurs same-sized.

Abdomen. Tergites pubescent (Fig. 7A, G); Supra anal plate posterior margin straight (Fig. 7E).

Male. Anterior margin of median projection of metanotum rounded posterior margin wider than anterior margin in dorsal view (Fig. 7D). Subgenital plate as long as wide, posterior margin convex (Fig. 7F).

Male genitalia (Fig. 8A–D). Pseudepiphallus: pseudepiphallic sclerite slightly upcurved in lateral view, anterior margin V-shaped on median region, lateral region upcurved in lateral view (Fig. 8A, C). LLophi curved inwards (Fig. 8A, B); posterior margin truncated in dorsal and ventral views; inner margin membranous; outer margin sclerotized, thin (Fig. 8A, B). PsP same-sized as LLophi, posterior margin divided into two lobes, not surpassing posterior margin of pseudepiphallic sclerite in dorsal and ventral views (Fig. 8B); apex of dorsal lobe fingershaped, inclined inwards; apex of ventral lobe finger-shaped, shorter than dorsal lobe (Fig. 8B). r elongate, longer than pseudepiphallic sclerite, flattened laterally (Fig. 8A–C). Ectophallic invagination: EctAp longer than LLophi, straight, inclined to outwards in dorsal and ventral views (Fig. 8A); arc not complete, curved posteriorly; ventral projections of ectophallic invagination short, same size as arc (Fig. 8B).

Female. Body larger than male (Fig. 7G, H). Subgenital plate wider than long, posterior margin concave on the middle (Fig. 7J). Ovipositor as in fig. 7I, J.

Female genitalia. Copulatory papilla (Fig. 8E–G) longer than wide, slightly curved downwards in lateral view; ventral face two times longer than dorsal face; ventral face with a median split.

Coloration. Male and female with similar coloration. Occiput, vertex, pronotum, and abdominal tergites medium brown to yellowish-brown (Fig. 7A, G). Occiput with two median and two lateral longitudinal stripes medium brown (Fig. 7A, G). Face light brown with stripes medium brown surrounding antennal scapes in frontal view (Fig. 7C); antennal scape light brown to yellowish-brown, antennomeres light brown interspaced by some medium brown ones. FWs somewhat translucent, yellowish; median projection of metanotum brownish-orange (Fig. 7D); abdominal tergites with a median band dark brown, medium brown spotted laterally (Fig. 7A, G); last abdominal tergite dark brown; sternites light brown almost whitish; supra anal plate anterior portion medium brown, posterior portion light brown (Fig. 7E, I); subgenital plate reddish-brown with anterior margin light brown (Fig. 7F); female subgenital plate light brown, darker medially (Fig. 7J); cerci anterior margin light brown, middle region medium brown, getting lighter on the apex (Fig. 7I); ovipositor apex reddish-brown (Fig. 7 I, J). FI and FII light brown, medium brown spotted, TI and TII light brown with two maculae median brown on dorsal region, one distal and one proximal; FIII yellowish-brown to light brown, medium brown striped, distal apex medium brown; TIII light brown, proximal portion dark brown, dark brown spotted on the base of subapical spurs; spurs light brown with apex dark brown; tarsomeres light brown (Fig. 7B, H).
