Crucisternum is a Neotropical genus of water scavenger beetles in the family Hydrophilidae represented by seven described species known from the Guiana Shield Region.[1]
The genus Crucisternum was described for the first time by Girón & Short in 2018.[2]
It belongs in the subfamily Acidocerinae and contains seven described species from Brazil (Minas Gerais, Pará), French Guiana, Guyana, Suriname, and Venezuela.[1][2]
Description
Small beetles (2.0–2.5 mm), smooth and shiny dorsally, orange-brown to dark brown in coloration, with long maxillary palps. The most salient characteristic of the genus is the presence of a longitudinal carina on the prosternum, which is accompanied by a cruciform elevation on the mesoventrite. A complete diagnosis was presented by Girón and Short.[1][2]
