Abstract: | In this study, the new genus Spanglerelmis Polizei & Bispo is described; Microcylloepus ochus Hinton, 1940 is synonymized with Microcylloepus femoralis Hinton, 1940, and transferred to the new genus; and two new species, S. xiririca gen. et sp. nov. and S. timburi gen. et sp. nov. are described. The new genus can be characterized by the combination of the following characters: 1) pronotum without transverse, longitudinal or oblique impressions, sulci or gibbosities on disc; 2) elytra with a carina on interval III and two sublateral carinae on intervals V and VI; 3) mesoventrite with sides strongly raised; and 4) femora with an oblique belt of tomentum dorsally and a transverse belt ventrally. The specimens of the two new species were collected mainly in riffes of unimpacted streams in the Atlantic Forest in São Paulo State, Brazil. Scanning electron microscope images, an identifcation key for the genus and habitat notes are also presented. |
