Crenitulus suturalis
(LeConte, J. L., 1866)
Crenitulus suturalis is a small water scavenger beetle ( Hydrophilidae) with a broad distribution across the Americas, ranging from the eastern and central United States through Central America to South America. The was originally described by John Lawrence LeConte in 1866 and has been historically confused with or included in discussions of darkling beetles due to taxonomic name similarities with unrelated species. As a member of the Chaetarthriinae, it occupies moist or aquatic microhabitats distinct from the arid-adapted darkling beetles with which it shares no close relationship.

Identification
Distinguished from other Crenitulus and chaetarthriine hydrophilids by genitalic and subtle external morphological characters; precise identification requires examination by a in Hydrophilidae . Not to be confused with Eleodes suturalis (Tenebrionidae), a darkling beetle with which it shares only a similar specific epithet and no taxonomic relationship.

Distribution
Eastern and central United States (Arizona, Delaware, Florida, Georgia, Indiana, Kansas, Kentucky, Maryland, Mississippi, New York, Pennsylvania, South Carolina, Texas, Virginia); Mexico; Belize; Guatemala; Honduras; Nicaragua; Rica; Colombia; Venezuela; French Guiana; Peru; Paraguay; Brazil; Argentina; Jamaica; Cuba; Dominican Republic.
Similar Taxa
- Eleodes suturalisShares similar specific epithet and was historically confused due to name similarity, but belongs to entirely different (Tenebrionidae) with contrasting (arid grasslands vs. moist ), (defensive -stand absent in Hydrophilidae), and phylogenetic placement.
Misconceptions
The has been tangentially involved in taxonomic confusion due to the unrelated darkling beetle Eleodes suturalis, which was discussed in entomological literature under similar names. Crenitulus suturalis (Hydrophilidae) and Eleodes suturalis (Tenebrionidae) are not closely related and occupy fundamentally different .

Taxonomic history
Originally described by J.L. LeConte in 1866; current placement in Crenitulus reflects modern Hydrophilidae classification. The Crenitulus contains few and is not well represented in popular or field literature.
Data limitations
Available sources provide primarily nomenclatural and distributional data; biological and ecological information for this remains sparse in accessible literature.
