Tobochares Explained

Tobochares is a Neotropical genus of water scavenger beetles in the family Hydrophilidae represented by 24 described species known from the Guiana Shield Region.^[1]

Taxonomy

The genus Tobochares belongs in the subfamily Acidocerinae. It was first described by Short and García in 2007.^[2] Since then, as more species are discovered in the seepages of the Guiana Shield Region, there have been two additional papers describing several additional species.^{[3] [4]}

Description

Small beetles (1.5–2.6 mm), yellowish brown, orange brown to dark brown in coloration; eyes entire to emarginate; maxillary palps from short and slender to very short and stout. The elytral punctation and sculpture is highly variable in this genus. There is also variation in the shape of the male genitalia and wing development. A complete diagnosis was presented by Girón and Short.

Habitat

Most Tobochares are considered seepage specialists. One species (Tobochares fusus) has been also collected in rotten fruits away from water sources.
