Species Guides
1- Ichnea elongata(checkered beetle)
Ichnea is a of checkered beetles in the Cleridae, established by Laporte in 1838. The genus contains at least four described distributed across North and South America. Ichnea belongs to the Korynetinae, a group of clerid beetles characterized by elongated body forms. The genus remains poorly studied, with limited ecological and behavioral data available.

Identification
Members of Ichnea can be distinguished from other Korynetinae by their elongated, somewhat cylindrical body shape. The genus lacks the strongly flattened form seen in some related clerid genera. -level identification requires examination of antennal structure, elytral punctation patterns, and male genitalia. Ichnea marginella and I. opaca, both described by Klug in 1842, are historically associated with South America, while I. elongata (Knull, 1939) and I. digna (Wolcott) are North American.
Distribution
The has a disjunct distribution spanning North and South America. Ichnea elongata occurs in the southwestern United States, while I. digna has been recorded from the southern United States. Ichnea marginella and I. opaca are documented from South America, with records primarily from Brazil.
Similar Taxa
- KorynetesBoth belong to Korynetinae and share elongated body forms, but Korynetes typically have more pronounced antennal clubs and different elytral sculpturing.
- NecrobiaNecrobia ( Cleridae, Korynetinae) have a more compact, less elongate body and are frequently associated with stored products, whereas Ichnea species are more slender and primarily found in natural .

Taxonomic history
The was established by Laporte in 1838, though some sources cite 1836. The four described have not been comprehensively revised since their original descriptions, and the genus may contain additional undescribed species.
Data deficiency
With only five observations recorded in iNaturalist and minimal recent taxonomic treatment, Ichnea represents a data-deficient within Cleridae. Most ecological and biological information must be inferred from better-studied relatives in Korynetinae.
