Type locality. Colombia, Amazonas Department Leticia (4°7'49"S, 69°58'7"W). GoogleMaps

Etymology. The specific epithet is a gentilic adjective that refers to Colombia, where this species can be found. Type material. Holotype male. Holotype: Amazonas. Leticia. Km11 via Tarapaca. 26/10/02 alt. 170m. 6.sist.A. 091-059 (MZSP).

Diagnosis. General aspect similar to D. manauara n. sp., differing mainly in male genitalia characters. The phallic complex of D. colombiana Souza-Dias n. sp. is longer than in D. manauara Souza-Dias n. sp.; pseudepiphallic parameres (PsP) highly sclerotized; PsP2 with two pairs of distinct projections: first projection elongated, upcurved, larger than in D. manauara n. sp.; second projection small, medial, semicircular, visible in dorsal view; PsP1 elongated, outer face of apex pointed, inner face broadly rounded; ectophallic arc straight, anterior to median part of pseudepiphallic sclerite; ventral projections not bent, large, apex wide, curved outwards. Ectophallic fold sclerotized, longer than in D. manauara n. sp., surrounding apex of medio-posterior projection of endophallic sclerite.

Description. In addition to the characters of the genus:

Head. Occiput and vertex coloration medium brown, almost uniform, with thick setae ( Figs. 5 A–C View FIGURE 5 ). 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. 5 A–C, F View FIGURE 5 ). Antennal scape longer than wide, scape and pedicel yellowish brown ( Figs. 5A, B View FIGURE 5 ); proximal antennomeres yellowish brown, medial and distal medium brown ( Figs. 5A, F View FIGURE 5 ). Frons yellowish brown ( Fig. 5F View FIGURE 5 ). In frontal view, gena medium brown ( Fig. 5F View FIGURE 5 ). In lateral view, gena yellowish brown divided by incomplete dark brown stripe, with dark brown spots ( Fig. 5C View FIGURE 5 ). Mandibles light to medium brown ( Fig. 5F View FIGURE 5 ). Clypeus medium brown, central portion light brown; labrum greyish brown ( Fig. 5F View FIGURE 5 ). Maxillary palpi elongated, joints 3–5 elongated, pilose, joint 5 longest ( Fig. 5E View FIGURE 5 ); whitish, ventral half light brown ( Fig. 5E View FIGURE 5 ); fifth joint whitish, apex light brown, curved, rounded ( Fig. 5E View FIGURE 5 ).

Thorax. Pronotum DD longer than wide, medium brown, borders darker than central part, cephalic margin with bristles ( Figs. 5 A–C View FIGURE 5 ). DD cephalic margin slightly convex, DD caudal margin sub-straight, LL ventrocephalic angle curved, ventro-caudal angle oblique ( Figs. 5 A–C View FIGURE 5 ).

Legs. Legs I and II light to medium brown, not annulated, pubescent, with thick setae. Tympanum on inner face of TI. TI and TII with two ventral spurs. TII with two ventral spurs, 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. 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 ( Fig. 5A View FIGURE 5 ); dark brown, coloration almost uniform ( Fig. 5A View FIGURE 5 ). Sternites light to medium brown. Cerci medium brown. Supra anal plate light to medium brown, pubescent, not constricted medially ( Fig. 5H View FIGURE 5 ); proximal margin slightly concave, distal margin straight, wide, without extended angles ( Fig. 5H View FIGURE 5 ). Subgenital plate elongated, light brown, pubescent ( Fig. 5G View FIGURE 5 ); proximal margin concave, median portion of distal margin almost straight ( Fig. 5G View FIGURE 5 ).

Male. Male FWs short, rounded, reaching half of abdomen ( Fig. 5A View FIGURE 5 ); right FW medium brown ( Figs. 5A, B View FIGURE 5 ), pilose, apex light brown; without specialized veins or areas for sound production and propagation; left FW membranous, translucent, lateral field medium brown, with sparse setae ( Fig. 5D View FIGURE 5 ). Male genitalia. Male genitalia longer than D. manauara n. sp., bearing a pair of genital glands within pseudepiphallic sclerite, connected to tubular pseudepiphallic arms ( Figs. 6 A–C View FIGURE 6 ). Pseudepiphallus: pseudepiphallic sclerite transverse, with phallic glands connected to two dorsal pseudepiphallic arms tubular ( Figs. 6 A–C View FIGURE 6 ); pseudepiphallic arms curved outwards ( Figs. 6A, B View FIGURE 6 ); apex with opening duct, rounded. Rami elongated, reaching apex of ectophallic apodemes ( Fig. 6A View FIGURE 6 ). Pseudepiphallic parameres (PsP) highly sclerotized ( Figs. 6 A–C View FIGURE 6 ); PsP2 with two pairs of distinct projections: one elongated, upcurved, larger than in D. manauara n. sp., second small, medial, semicircular, visible in dorsal view ( Fig. 6A View FIGURE 6 ); PsP1 elongated, outer face of apex pointed, inner face broadly rounded ( Figs. 6B, C View FIGURE 6 ). Ectophallic invagination. Ectophallic apodemes elongated, thin ( Figs. 6A, B View FIGURE 6 ); ectophallic arc straight, anterior to median part of pseudepiphallic sclerite ( Fig. 6A View FIGURE 6 ); dorsal projections of ectophallic invagination absent; ventral projections large, apex wide, curved outwards ( Fig. 6B View FIGURE 6 ). Ectophallic fold sclerotized, longer than in D. manauara n. sp., surrounding the apex of medio-posterior projection of endophallic sclerite ( Figs. 6A, B View FIGURE 6 ). Endophallus. Endophallic sclerite large, flat ( Figs. 6A, B View FIGURE 6 ); latero-posterior projections shorter than in D. manauara n. sp.; medio-posterior projection elongated ( Figs. 6A, B View FIGURE 6 ). Endophallic apodeme paired, curved outwards.

Female. Unknown.
