. The overall shape of the male genitalia is diagnostic for this species (Fig. 23): characteristics as parameres conspicuously shorter than median lobe, evenly wide from base to apical third with outer margin subparallel basally, and median lobe with apex strongly acuminate distinguish this species from the other Neotropical species.

Ground punctation on labrum, clypeus and frons fine, distance between punctures 1.5–2.0x the width of one puncture (Fig. 28). Systematic punctures on labrum consisting of several punctures about twice the diameter of surrounding punctures, forming an irregular row on median portion, sometimes bearing short, fine setae. Clypeus with an irregular row of distinct systematic punctures on anterior portion, in both sides, with few scattered ones, about twice larger than surrounding punctures, bearing short, fine setae (Fig. 28). Frons with irregular row of distinct systematic punctures along frontoclypeal suture, about 2.0–3.0× larger than surrounding punctures and some less distinct scattered systematic punctures mesally of eyes, both bearing short, fine setae. Anterior clypeal margin with narrow emargination, round to angulate shaped, exposing a gap between clypeus and labrum (Fig. 28). Anterior margin of labrum slightly concave medially. Mandibles bifid at apex. Maxillary palpi somewhat longer than maximum width of head (0.2x longer); palpomeres subequal in length (Figs. 1 and 2). Labial palpi about half the width of mentum; Ultimate palpomere with a preapical long seta (Fig. 12). Mentum bare, with some short setae on lateral margins, rather punctuate, somewhat rugose, with deep notch on anterolateral margin and very deeply depressed on anterocentral half; anterocentral notch on a raised anterior margin, developed and triangular (Figs. 9, 10 and 11).

” is the Latinized version of the Portuguese word “Fluminense”, in which is a popular name used to refer to those born in Rio de Janeiro State. This specific name refers to the wide distribution of the species in the state, as well as to its occurrence in backwater margins of streams, unusual among species of the genus.

. The wide range of habitats, altitude and temperature observed on the distribution of the species may have influence on the total size of the species. It was observed that the specimens collected at high altitudes and lower temperatures are bigger. Some morphometric and ecological analyses are needed to confirm this hypothesis.
