(Figs 1A, 3C)
Diagnosis. This species is easily recognized by having the aedeagal dorsal valve slender, the apex of inner median filament almost aligned with apex of aedeagal dorsal lobes, the ventral margin of the harpe and cuspis with an extreme excavation and the basivolsellar protuberance small and narrow.
Description. Head. Mandible with two distal teeth. Median clypeal lobe subtrapezoidal, with one angulate short tooth; median clypeal carina high in profile, incomplete apically, arched in profile. Frons coriaceous, punctures small and dense. Vertex crest straight or nearly so. Dorsal pronotal area with anterior margin coarse. Tergal process submedian, with tuft of setae without depression. Posterior hypopygeal margin strongly outcurved. Genitalia. Harpe entirely wide, apical margin truncate, abaxial margin not projected; gonostipes shorter than harpe, ventral margin excavated almost until outer margin of basivolsella; digitus short, basidorsal corner strongly projected; basivolsella poorly delimited with narrow protuberance, without spines; aedeagal ventral valve with apex anterior to apex of dorsal one, wide, progressively narrowing apicad; inner margin straight; outer margin sinuous, slightly curved dorsad; aedeagal dorsal valve, with two pairs of apical lobe; outer lobe long, narrow, apical margin rounded and posterad; apex of inner median filament aligned with apex of lobe, directed posterad; basal cover plate entirely wide, posterior margin completely incurved; apodeme extending beyond genital ring.
Variations. Median clypeal lobe ill-defined, tuft of setae is more dense, dorsal corner of digitus much longer and sharper.

Distribution. Ecuador, Costa Rica.
Etymology. This species is named after the pedagogue Carolina Bori, who worked for the regulation of Psychology in Brazil.
Remarks. It is similar to D. grazieliae sp. nov. by having the dorsal margin of harpe straight, with the main portion entirely narrow, the basal cover plate incurved medially, and the aedeagal dorsal lobes long. However D. boriae sp. nov. has the apex of inner median filament almost aligned with apex of the outer lobes, the ventral margin of gonostipes deeply excavated, the digitus wide, and basivolsellar protuberance pointed, whereas D. grazieliae sp. nov. has the apex of inner median filament anterior to apex of aedeagal dorsal lobes, the digitus narrow, the basivolsellar protuberance wide, and the ventral margin of gonostipes not deeply excavated.
