Diagnosis. This species is separated from the other species of Neometrypus by the following characters: pronotum dark brown with a longitudinal median band brownish orange; abdominal tergites crossed lengthwise by median and lateral bands dark brown, brownish orange between the bands; width of anterior and posterior margins of median projection of metanotum similar in dorsal view; supra anal plate posterior margin sub-straight; subgenital plate posterior margin slightly concave. Male genitalia: dorsal lobe of PsP two times longer than ventral lobe; apex of r curved posteriorly forming a “v”.

Description. General morphology. Head. Fastigium as long as wide, pubescent ( Fig. 5A ). Lateral ocelli rounded, median ocellus absent ( Fig. 5C ), frons smooth ( Fig. 5C ). Antennal scape longer than wide, inner margin with bristles. Maxillary palpi articles 4 and 5 almost same-sized, article 3 longer; article 5 upcurved ( Fig. 5B ).

Thorax. DD as long as wide, covered by bristles. DD cephalic margin straight, caudal margin slightly convex ( Fig. 5A ). LL ventro-cephalic angle rounded; ventro-caudal angle gradually ascendant in lateral view ( Fig. 5B ). FWs surpassing posterior margin of metanotum ( Fig. 5A ).

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, six or seven spines above subapical spurs on inner and outer sides. TIII inner apical spurs: iad>iam>iav; outer apical spurs: oam>oav>oad. Basitarsus dorsal spines 3/2; outer and inner apical spurs same-sized.

Abdomen. Tergites pubescent ( Fig. 5A, B ); Supra anal plate posterior margin sub-straight ( Fig. 5E ).

Male. Median projection of metanotum anterior margin rounded, anterior and posterior margins width similar in dorsal view ( Fig. 5D ). Subgenital plate as long as wide, posterior margin slightly convex ( Fig. 5F ).

Male genitalia ( Fig. 6A–D ). Pseudepiphallus: pseudepiphallic sclerite straight in lateral view, anterior margin V-shaped on median region, lateral region upcurved in lateral view. LLophi straight, inclined inwards, posterior margin rounded in dorsal and ventral views ( Fig. 6A, B ); inner margin membranous, outer margin sclerotized, thin ( Fig. 6A, B ). 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. 6A, B ); apex of dorsal lobe finger-shaped, curved inwards, two times longer than ventral lobe ( Fig. 6B ); apex of ventral lobe rounded. r elongate, same size as pseudepiphallic sclerite, flattened laterally, apex curved posteriorly forming a “v” ( Fig. 6A–C ). Ectophallic invagination: EctAp longer than LLophi, straight, slightly inclined to outwards in dorsal and ventral views ( Fig. 6A ); arc not complete, curved posteriorly ( Fig. 6B ); ventral projections of ectophallic invagination short, shorter than arc ( Fig. 6B ).

Female. Unknown.

Coloration. Occiput and vertex yellow; pronotum dark brown with a median longitudinal band brownish orange; abdominal tergites dark brown and brownish orange ( Fig. 5A ). Occiput with two median longitudinal stripes light gray ( Fig. 5A ). Face light brown with grey stripes under eyes in frontal view ( Fig. 5C ); antennal scape and antennomeres yellowish-brown. FWs slightly translucent, yellow; median projection of metanotum reddish-brown ( Fig. 5A ); abdominal tergites crossed lengthwise by median and lateral bands dark brown, brownish orange between the bands ( Fig. 5A ), last abdominal tergite dark brown; sternites light brown; supra anal plate dark brown ( Fig. 5E ); subgenital plate reddish-brown ( Fig. 5F ); cerci light brown. FI and FII light brown, medium brown spotted, TI and TII light brown; FIII light brown, slightly striped, distal apex dark brown; TIII dark brown, distal portion getting lighter; spurs light brown with apex and basis medium brown; tarsomeres light brown ( Fig. 5B ).
