Same data as for previous paratype | PSD 571 | MNRJ-ENT6-29507; MNRJ . 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 ). TABLE 5. Measurements in mm of Neometrypus lopesae n.sp.
