 Material. Holotype male imago from COLOMBIA: P. N. Farallones de Cali, Peñas Blancas, río Pichinde, N 3º 25' 45", W 76º 39' 27", 2.000 m, 17-18-III-1999, E. Domínguez, M.C. Zuñiga & C. Molineri; allotype female imago, 7 male imagos and 1 male nymph paratypes, same data as holotype; 7 male and 1 female imagos and 2 male nymphs paratypes from COLOMBIA: Boyacá, Municipio de Arcabuco, Santuario de Flora y Fauna de Iguaque, quebrada Carrizal, N 5º 42' 37", W 73º 27' 43", 2720 m, 6-II-1997, E. Domínguez, M. Pescador & L. Baena cols. All material deposited at MUSENUV, except 4 male imagos from rio Pichinde, 3 male, 1 female imago and 2 nymphs from quebrada Carrizal, deposited at IFML.   
 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; 2) eyes of male meeting on dorsum of head (Figs. 14–15); 3) first forceps segment around 2.2 times length of styliger plate, and curved medially (Figs. 41–42); 4) hind femora yellowish with black shading restricted to apical ¼; 5) cerci yellowish.
