The specimens were captured in running water or when flying towards light in the evening. DescriptionThis species resembles other smaller or medium-sized species of Neptosternus. It may be recognized by the size, fairly widely oval shape of its body, the colour-patterns of pronotum and elytra, and the shape of the penis in the males. Its length is between {{convert|2.8|and|3.0|mm|in}}, while its breadth is between {{convert|1.5|and|1.6|mm|in}}. It shape is elongate and oval, moderately convex dorsally; and its upper surface shining. Its head and antennae are yellowish in colour, with fine and remote punctation on the head. It also has a reticulate surface. The pronotum is yellowish with a narrow transverse slightly darker band in the middle, and an anterior submarginal row of punctures that are irregular.[1] References1. ^1 Hendrich, L., and M. Balke.
