Diagnosis. This species is separated from the other species of Neometrypus by the following characters: cerci anterior margin light brown, middle region medium brown, getting lighter on the apex; seven or eight spines above subapical spurs on inner and outer sides of TIII; anterior margin of median projection of metanotum slightly pointed, posterior margin almost same-sized than anterior margin in dorsal view. Male genitalia: LLophi posterior margin truncated in dorsal and ventral views.

Description. General morphology. Head. Fastigium as long as wide, pubescent ( Fig. 15A, G ). Lateral ocelli rounded, median ocellus absent ( Fig. 15C ); frons smooth ( Fig. 15C ). Antennal scape longer than wide, inner margin with bristles. Maxillary palpi articles 4 and 5 almost same-sized, article 3 slightly longer; article 5 slightly upcurved ( Fig. 15B, H ).

Thorax. DD longer than wide, covered by bristles. DD cephalic margin sub-straight, caudal margin straight ( Fig. 15A, G ). LL ventro-cephalic angle rounded; ventro-caudal angle gradually ascendant in lateral view ( Fig. 15B, H ). FWs surpassing posterior margin of metanotum ( Fig. 15A, 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, seven 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 (rarely 3/1); outer and inner apical spurs same-sized.

Abdomen. Tergites pubescent ( Fig. 15A, G ); Supra anal plate posterior margin rounded ( Fig. 15E, I ).

Male. Anterior margin of median projection of metanotum slightly pointed posterior margin almost same-sized than anterior margin in dorsal view ( Fig. 15D ). Subgenital plate as long as wide, posterior margin convex ( Fig. 15F ).

Male genitalia ( Fig. 16A–D ). Pseudepiphallus: pseudepiphallic sclerite slightly upcurved in lateral view, anterior margin V-shaped on median region, lateral region upcurved in lateral view ( Fig. 16A–C ). LLophi curved inwards, posterior margin truncated in dorsal and ventral views; inner margin membranous, outer margin sclerotized, thin ( Fig. 16A, 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; apex of dorsal lobe finger-shaped, slightly curved inwards; apex of ventral lobe truncated ( Fig. 16B ). r elongate, longer than pseudepiphallic sclerite, flattened laterally ( Fig. 16A–C ). Ectophallic invagination: EctAp longer than LLophi, straight, slightly inclined to outwards in dorsal and ventral views ( Fig. 16A, B ); arc not complete, curved posteriorly; ventral projections of ectophallic invagination short, almost same size as arc ( Fig. 16B ).

Female. Body slightly larger than male ( Fig. 15B, H ). Subgenital plate wider than long, posterior margin concave on the middle ( Fig. 15J ). Ovipositor as in fig. 15I, J.

Female genitalia. Copulatory papilla ( Fig. 16E–G ) longer than wide, almost straight in lateral view; posterior margin somewhat prominent in dorsal view, truncated in lateral and ventral views; anterior margin on dorsal face rounded, anterior margin of ventral face concave. Median region on dorsal face depigmented.

Coloration. Male and female with similar coloration. Occiput, vertex, pronotum, and abdominal tergites medium brown to yellowish-brown ( Fig. 15A, B, G, H ). Occiput with two median and two lateral longitudinal stripes reddish ( Fig. 15A, G ). Face light brown to yellowish-brown with stripes gray forming a triangle centrally ( Fig. 15C ); antennal scape yellowish-brown, antennomeres light brown. FWs slightly translucent, yellowish; median projection of metanotum brownish-orange ( Fig. 15D ); abdominal tergites with medium brown spots on posterior margin and a median band dark brown fading on posterior margin, except on the last three tergites ( Fig. 15A, G ); last abdominal tergite dark brown; sternites light brown almost whitish with thin and short horizontal stripes dark brown on lateral posterior margins; supra anal ( Fig. 15E, I ) and subgenital ( Fig. 15F ) plates dark brown; female subgenital plate light brown ( Fig. 15J ); cerci anterior margin light brown, middle region medium brown, getting lighter on the apex; ovipositor apex reddish-brown ( Fig. 15I, J ). FI and FII light brown, medium brown spotted, TI and TII light brown to yellowish-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 to reddish-brown laterally; TIII medium to yellowish-brown, proximal portion medium to dark brown, dark brown spotted on the base of subapical spurs; spurs light brown with apex medium brown; tarsomeres yellowish-brown ( Fig. 15B, H ).
