Año: 2005 vol. 40 p. 247 - 254
Leptohyphodes Ulmer is a poorly known monotypic genus from NE of Brazil (Serra do Mar). It is the only genus in the family Leptohyphidae that shows divided eyes in the male. In the present paper the genus and species are redescibed, based on new material from all the stages. The eggs and female adults are described for the first time. Also male imagines of Tricorythodes ocellus Allen & Roback are described for the first time, showing markedly plesiomorphic genitalia. Leptohyphodes shows close affinities with the genera Tricorythodes and Haplohyphes.
