MOLINERI, Carlos. The species of Leptohyphidae (Ephemeroptera) from the Argentine and Bolivian Yungas: diagnoses, distribution, and keys. Rev. Soc. Entomol. Argent. [online]. 2010, vol.69, n.3-4, pp.233-252. ISSN 0373-5680.

The species of Leptohyphidae occurring in the Yungas cloud forest are studied. Eighteen species from five genera are known from the region, including the following new country records: Leptohyphes liniti Wang, Sites & McCafferty, L. maculatus Allen, L. nigripennis Molineri & Zúñiga, L. setosus Allen, and Tricorythodes hiemalis Molineri from Bolivia; Leptohyphes hirsutus Allen & Roback and L. petersi Allen from Bolivia and Argentina; and Tricorythodes quizeri Molineri from Argentina. Diagnoses, illustrations, and keys to distinguish the treated species are presented. The study of the distribution of these species revealed three different patterns: 1) a group of five species restricted to the Yungas; 2) a group of eight species that extend their ranges toward the montane forest in the north; and 3) a group of three species also present in southern areas (central Argentina and northern Patagonia).

Keywords : Austral Yungas; Bolivian Yungas; Mountain cloud forest; Mayfly; Pannota; Ephemerelloidea.
