Etymology: The species is dedicated to Maria del Carmen Zuñiga, friend and colleague for her enthusiasm and contributions to the knowledge of Colombian aquatic insects.

Discussion: H. zunigae sp. nov. can be separated from the other species of the genus by the following combination of characters. Imago: 1) General coloration dark (yellowish white heavily washed with blackish brown except terga III–VII with anterior margins with central area and corners not tinged), pattern as in Fig. 13 View FIGURES 13–18 ; 2 View FIGURES 1–6 ) eyes of male meeting on dorsum of head ( Figs. 14–15 View FIGURES 13–18 ); 3) first forceps segment around 2.2 times length of styliger plate, and curved medially ( Figs. 41–42 View FIGURES 37–47 ); 4) hind femora yellowish with black shading restricted to apical ¼; 5) cerci yellowish.
