Diagnosis. This species is separated from the other species of Neometrypus by the following characters: abdominal tergites with medium brown spots on posterior margin and a median band medium brown fading on posterior margin, except on the last three tergites. Male: anterior margin of median projection of metanotum sub-straight; Male genitalia: apex of ventral lobe of PsP finger-shaped, shorter than dorsal lobe, curved anteriorly; apex of r bifid; apex of EctAp curved laterally. Female genitalia: posterior margin of copulatory papilla truncated.

Description. General morphology. Head. Fastigium as long as wide, pubescent ( Fig. 17A, G View FIGURE 17 ). Lateral ocelli rounded, median ocellus absent ( Fig. 17C View FIGURE 17 ), frons smooth ( Fig. 17C View FIGURE 17 ). Antennal scape longer than wide, inner margin with bristles. Maxillary palpi articles 3, 4, and 5 almost same-sized, article; article 5 slightly upcurved ( Fig. 17B View FIGURE 17 ).

Thorax. DD longer than wide, covered by bristles. DD cephalic margin straight, caudal margin slightly convex ( Fig. 17A, G View FIGURE 17 ). LL ventro-cephalic angle rounded; ventro-caudal angle gradually ascendant in lateral view ( Fig. 17B, H View FIGURE 17 ). FWs not surpassing posterior margin of metanotum ( Fig. 17A, G View FIGURE 17 ).

Legs. TI with three apical spurs, two ventral, one dorsal. TII with four apical spurs, two ventral, two dorsal. TIII subapical spurs with two (sometimes one) spines between each spur, nine 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 3/1 (rarely 2/1); outer and inner apical spurs same-sized.

Abdomen. Tergites pubescent ( Fig. 17A, G View FIGURE 17 ); Supra anal plate posterior margin rounded ( Fig. 17E, I View FIGURE 17 ).

Male. Anterior margin of median projection of metanotum sub-straight; posterior margin wider than anterior margin in dorsal view, trapezoidal ( Fig. 17D View FIGURE 17 ). Subgenital plate longer than wide, posterior margin rounded ( Fig. 17F View FIGURE 17 ).

Male genitalia ( Fig. 18A–D View FIGURE 18 ). Pseudepiphallus: pseudepiphallic sclerite straight in lateral view, anterior margin concave on median region, lateral region upcurved in lateral view ( Fig. 18A–C View FIGURE 18 ). LLophi curved inwards, posterior margin rounded in dorsal and ventral views; inner margin membranous, outer margin sclerotized, thin ( Fig. 18A View FIGURE 18 ). PsP same-sized as LLophi, posterior margin divided into two lobes, reaching posterior margin of pseudepiphallic sclerite in dorsal and ventral views ( Fig. 18A, B View FIGURE 18 ); apex of dorsal lobe finger-shaped, curved inwards; apex of ventral lobe finger-shaped, shorter than dorsal lobe, curved anteriorly ( Fig. 18B View FIGURE 18 ). r elongate, longer than pseudepiphallic sclerite, flattened laterally, apex bifid ( Fig. 18A–C View FIGURE 18 ). Ectophallic invagination: EctAp longer than LLophi, straight, inclined to outwards in dorsal and ventral views, apex curved laterally ( Fig. 18A–C View FIGURE 18 ); arc not complete, curved posteriorly; ventral projections of ectophallic invagination short, same size as arc ( Fig. 18B View FIGURE 18 ).

Female. Body larger than male ( Fig. 17G, H View FIGURE 17 ). Subgenital plate wider than long, posterior margin concave on the middle ( Fig. 17J View FIGURE 17 ). Ovipositor as in fig. 17I, J.

Female genitalia. Copulatory papilla ( Fig. 18E–G View FIGURE 18 ) longer than wide, straight in lateral view; distal margin truncated; proximal margin of dorsal and ventral faces rounded. Anterior region of dorsal face depigmented.

Coloration. Male and female with similar coloration. Occiput, vertex, pronotum, and abdominal tergites light brown to yellowish-brown ( Fig. 17A, G View FIGURE 17 ). Occiput with two median and two lateral longitudinal stripes medium brown ( Fig. 17A, G View FIGURE 17 ). Face light brown with stripes medium brown on the middle and under antennal scapes in frontal view ( Fig. 17C View FIGURE 17 ); antennal scape light brown, antennomeres light brown. FWs slightly translucent, light brown; median projection of metanotum yellow, anterior margin whitish ( Fig. 17D View FIGURE 17 ); abdominal tergites with medium brown spots on posterior margin and a median band medium brown fading on posterior margin, except on the last three tergites ( Fig. 17A, G View FIGURE 17 ), last abdominal tergite dark brown; sternites light brown almost whitish; supra anal plate anterior portion medium brown, posterior portion light brown ( Fig. 17E View FIGURE 17 ); subgenital plate ocher, anterior margin lighter ( Fig. 17F View FIGURE 17 ); female subgenital plate light brown ( Fig. 17J View FIGURE 17 ); cerci light brown; ovipositor apex reddishbrown ( Fig. 17I, J View FIGURE 17 ). FI and FII light brown, medium brown spotted, TI and TII light brown median brown spotted; FIII yellowish-brown to light 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. 17B, H View FIGURE 17 ).
