Diagnosis. This species is separated from the other species of Neometrypus by the following characters: occiput and vertex yellowish-brown, pronotum and abdomen dark brown; basitarsus dorsal spines 2/2 or 3/3. Male: Median projection of metanotum trapezoidal. Male genitalia: median region of r prominent laterally in dorsal and ventral views; apex of ventral lobe of PsP finger-shaped, shorter than dorsal lobe. Female genitalia: copulatory papilla anterior margin rounded on dorsal face, straight on ventral face, shorter than dorsal.
Description. General morphology. Head. Fastigium as long as wide, pubescent (Fig. 11A, G). Three ocelli, the median reduced, slightly under lateral ones in frontal view (Fig. 11C); lateral ocelli rounded. Frons smooth (Fig. 11C). Antennal scape longer than wide, inner margin with bristles. Maxillary palpi articles 4 and 5 almost samesized, article 3 slightly longer; article 5 upcurved (Fig. 11B).
Thorax. DD longer than wide, covered by bristles. DD cephalic margin straight, caudal margin slightly convex (Fig. 11A, G). LL ventro-cephalic angle rounded; ventro-caudal angle gradually ascendant in lateral view (Fig. 11B, H). FWs surpassing posterior margin of metanotum (Fig. 11A, G).
Legs. TI with three apical spurs, two ventral, one dorsal. TII with four apical spurs, two ventral and two dorsal. TIII subapical spurs with two or three 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 2/2 or 3/3; outer and inner apical spurs same-sized.
Abdomen. Tergites and sternites pubescent (Fig. 11A, G, F); supra anal plate posterior margin rounded (Fig. 11E, I).
Male. Median projection of metanotum trapezoidal, anterior margin slightly rounded (Fig. 11D). Subgenital plate longer than wide, posterior margin slightly rounded (Fig. 11F).
Male genitalia (Fig. 12A–D). Pseudepiphallus: pseudepiphallic sclerite slightly upcurved in lateral view, anterior margin V-shaped on median region, lateral region upcurved in lateral view (Fig. 12A, C). LLophi curved inwards, posterior margin rounded in dorsal and ventral views; inner margin membranous, outer margin sclerotized, thin (Fig. 12A, 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. 12B); apex of dorsal lobe finger-shaped, inclined inwards (Fig. 12A, B); apex of ventral lobe finger-shaped, shorter than dorsal lobe. r elongate, longer than pseudepiphallic sclerite, flattened laterally, median region prominent laterally in dorsal and ventral views (Fig. 12A–D). Ectophallic invagination: EctAp same size as LLophi, slightly curved inwards, inclined to outwards in dorsal and ventral views (Fig. 12A, B); arc not complete, curved posteriorly; ventral projections of ectophallic invagination very short, shorter than arc (Fig. 12B).
Female. Body larger than male (Fig. 11G, H). Subgenital plate as long as wide, posterior margin almost straight on the middle (Fig. 11J). Ovipositor as in fig. 11I, J.
Female genitalia. Copulatory papilla (Fig. 12E–G) longer than wide, straight in lateral view; posterior margin thinner than anterior in dorsal and ventral views; anterior margin rounded on dorsal face, straight on ventral face, shorter than dorsal. Median region on ventral face depigmented.
Coloration. Male and female with similar coloration. Occiput and vertex yellowish-brown, pronotum and abdominal tergites dark brown (Fig. 11A, B, G, H). Occiput with two medians longitudinal grayish stripes (Fig. 11A, G). Face light brown to yellowish-brown with two median stripes (Fig. 11C); antennal scape and antennomeres yellowish-brown. FWs slightly translucent, dark yellow; median projection of metanotum dark brown, anterior margin whitish (Fig. 11D); abdominal tergites without longitudinal median band (Fig. 11A, G); sternites reddish-brown to dark brown; supra anal plate medium to dark brown (Fig. 11F), subgenital plate dark brown (Fig. 11F); female subgenital plate grayish brown (Fig. 11J); cerci anterior portion medium brown, getting lighter on the apex; ovipositor apex yellow (Fig. 11I). FI and FII light brown, medium brown spotted, TI and TII light brown to yellowish-brown; FIII yellowish-brown to light brown, medium brown striped; TIII medium to dark brown; spurs light brown with apex dark brown; tarsomeres light brown (Fig. 11B, H).
