(Figs 1C, 4A)
Diagnosis. This species is easily recognized by having the aedeagal dorsal valve much smaller than harpe, gonostipe and aedeagal ventral valve, the apex of inner median filament short and directed dorsad, the basal cover plate very wide, and the aedeagal ventral valve much higher than aedeagal dorsal valve.
Description. Head. Mandible with two distal teeth. Median clypeal lobe trapezoidal, with one angulate tooth; median clypeal carina high in profile, incomplete apically, straight in profile or nearly so. Frons coriaceous, punctures large and dense. Vertex crest weakly incurved. Dorsal pronotal area with anterior margin coarse. Tergal process submedian, consisting of tuft with few setae, without depression. Posterior hypopygeal margin straight or nearly so. Genitalia. Harpe entirely wide, apical margin rounded, abaxial margin not projected; gonostipes shorter than harpe, ventral margin not excavated until outer margin of basivolsella; digitus short, basidorsal corner poorly projected; basivolsella without protuberance, without spines; aedeagal ventral valve with apex posterior to apex of dorsal one wide, progressively narrowing apicad; inner margin sinuous; outer margin sinuous, curved laterad; aedeagal dorsal valve narrow, with two pairs of apical lobe; outer lobe short, narrow, apical margin rounded, and mesad; apex of inner median filament aligned with apex of lobe, directed dorsad; basal cover plate entirely wide, posterior margin rounded; apodeme not extending beyond genital ring.

Distribution. Costa Rica, Panama.
Etymology. This species is named after the mathematician Elza Furtado Gomide, one of the pioneers in the field of Mathematics in Brazil.
Remarks. It is similar to D. napo sp. nov. by having the harpe entirely wide with dorsal margin straight, the aedeagal dorsal outer lobes short with apex of inner median filament dorsad. However, D. elzae sp. nov. has the basal cover plate very wide, the aedeagal ventral valve sinuous, and the digitus short and wide, whereas D. napo has the basal cover plate narrow, the aedeagal ventral valve straight, and the digitus long and narrow.
