Sindolus is a Neotropical genus of water scavenger beetles in the family Hydrophilidae represented by eight described species, ranging from Mexico to Argentina , and including one species recorded from Antigua in the Lesser Antilles.[1]

Taxonomy

The genus Sindolus belongs in the subfamily Acidocerinae. It was first described by David Sharp in 1882 to accommodate two Central American species.[2] Since 1919 Sindolus was considered a subgenus of the genus Helochares by d’Orchymont [3] and stayed in that category until a molecular-based phylogenetic analysis [4] supported its restitution at the category of genus.

Description

Small to sized beetles (2.5–5.0 mm), smooth and shiny dorsally, moderately to strongly convex in lateral view; yellowish, orange-brown, to brown in coloration, with long maxillary palps. The most distinctive characteristic of Sindolus is the presence of a sharp and strongly elevated (laminar) longitudinal carina on the mesoventrite. A complete diagnosis was presented by Girón and Short.[1]

Habitat

Some species of Sindolus have been collected in stagnant waters at low elevations in dry areas.[1]
