Diagnosis. Within the genus, D. manauara   n. sp. can be recognized by the following characters: pseudepiphallic parameres (PsP) highly sclerotized; PsP2 with two pairs of distinct projections: one elongated, upcurved, second small, medial, semicircular, visible in dorsal view; PsP1 elongated, outer face of apex pointed, inner face rounded; ectophallic arc curved, below the median part of pseudepiphallic sclerite; ventral projections of the ectophallic invagination bent on the half of its extension, distal half and apex linked to the rest of the projection; ectophallic fold sclerotized, surrounding the apex of medio-posterior projection of endophallic sclerite.

Description. In addition to the characters of the genus:

Head. Occiput and vertex medium brown, almost uniform, with thick setae ( Figs. 2 A –D View FIGURE 2 ). Fastigium wider than long, medium brown, with double row of thick setae, below vertex level and not separated from it by line or furrow ( Figs. 2 A –D, G View FIGURE 2 ). Antennal scape longer than wide, scape and pedicel light brown; proximal antennomeres light brown, medial and distal medium brown ( Figs. 2 A –D View FIGURE 2 ). Frons medium brown ( Fig. 2G View FIGURE 2 ). In frontal view, gena dark brown ( Fig. 2G View FIGURE 2 ). In lateral view, gena medium brown, not divided by stripe, with dark brown spots. Mandibles light to medium brown ( Fig. 2G View FIGURE 2 ). Clypeus medium brown, center light brown; labrum greyish brown ( Fig. 2G View FIGURE 2 ). Maxillary palpi elongated, joints 3–5 elongated, joint 4 longest; whitish, ventral half light brown (entirely light brown in some specimens); fifth joint whitish, apex light brown (medium brown in some specimens), curved, rounded ( Figs. 1 A –B View FIGURE 1 , 2J View FIGURE 2 ).

Thorax. Pronotum DD longer than wide, borders medium to dark brown (except cephalic margin), with thick setae, mainly on cephalic margin ( Figs. 2 A –F View FIGURE 2 ). DD cephalic margin slightly convex, DD caudal margin substraight, LL ventro-cephalic angle curved, ventral margin ascending, ventro-caudal angle gradually ascendant ( Figs. 2 A –F View FIGURE 2 ). Remarks. The holotype lost the setae on pronotum DD.

Legs. Legs I and II light to medium brown, not annulated, pubescent, with thick setae ( Figs. 1 A –B View FIGURE 1 , 2 A –B View FIGURE 2 ). Tympanum on inner face of TI. TI and TII with two ventral spurs. TII with two ventral spurs, and one dorsal—the outer dorsal is absent. FIII basis inflated; outer face light to medium brown, with dark brown maculae, inner face with same pattern ( Figs. 1 A –B View FIGURE 1 ). TIII light to medium brown, not annulated. Subapical spurs 4/4, with serrulation between and above them; inner distal subapical spur near upper apical; apical spurs 3/3, more developed on inner face; inner apical spurs: dorsal longest (iad), median slightly shorter (iam), ventral smaller (iav) (iad>iam>iav); outer apical spurs: median longest (oam), dorsal slightly shorter (oad), ventral smaller (oav) (oam>oad>oav). Basitarsus III with double row of spines.

Abdomen. Tergites slightly pubescent, without tergal glands; dark brown, coloration almost uniform ( Figs. 2A, D View FIGURE 2 ). Sternites light to medium brown. Cerci light to medium brown. Supra anal plate light to medium brown, not constricted medially; proximal margin slightly concave; distal margin straight, wide, without extended angles ( Fig. 2H View FIGURE 2 ). Subgenital plate elongated, light brown, pubescent; proximal margin concave; median portion of distal margin convex, with short angles, resembling an open “w ( Fig. 2I View FIGURE 2 ).

Male. Metanotum with two projections whitish, rounded ( Figs. 2 D –E View FIGURE 2 , 3 A –B View FIGURE 3 ); metanotal projections glandular ( Figs. 3A –B View FIGURE 3 ).
