Epipleoneura demarmelsi von Ellenrieder & Garrison 2008: 14, 17, 28, 29, figs. 22a–b, 32 a–c (new species, description of male, diagnosis, illustrations of cercus and epiproct in dorsal, lateral and postero-lateral view; illustration of genital ligula in lateral and ectal view, type material at FSCA, TWD, RWG, GSV). Garrison et al. 2010: 352, 353, 354, figs. 2321, 2324, 2325, 2332, 2333, 2334 (included in list of species, illustrations of wings, genital ligula in ectal and lateral view, cercus and epiproct in posterior and postero-lateral view, cercus in lateral view).

Specimens examined. 1 ♂, Guyana, narrow stream, affluent of Mau river, 20 km from Uranduirve falls, leg. A.B.M. Machado, viii 1960.

Diagnosis. see under E. capilliformis . Epipleoneura demarmelsi can be recognized by the following unique character combination: distal margin of epiproct trilobate, ventral margin of the epiproct convexly curved ( Fig. 4 b). Female unknown.

Distribution. Eastern Venezuela, western Guyana and Brazil in the Amazonas (R.W. Garrison, pers. com.) (type locality: Venezuela, Bolívar State, Río Churún at entrance to Salto Ángel, 05°58'N, 62°31'W). Notes. The examined specimen and the specimens in RWG collection (collected and determined by U.G. Neiss, IMPA, Manaus, Brazil) represent a new record for Guyana and Brazil respectively. Compared with the original description (von Ellenrieder & Garrison, 2008), this specimen has a slightly more pronounced medial lobe on the epiproct and a different color pattern: the dorsum of head is metallic green with some reddish reflections, the dorsal half of mesepisternum is metallic green and in ventral half brownish with some reddish reflections, mesepimeron is light brown and metathorax yellowish. Abdomen is dorso-laterally light brown.
