Genus Guides

Calochrominae is a of net-winged beetles ( Lycidae) established by Lacordaire in 1857. The subfamily contains at least 4 and more than 30 described , organized into two tribes: Calochromini and Slipinskiini. Members of this group share the characteristic with net-like venation typical of Lycidae.

Identification

Calochrominae can be distinguished from other lycid by the combination of: pronotum with lateral margins expanded and flattened; with reticulate venation forming a net-like pattern; and antennal structure varying by . The tribe Calochromini includes genera with relatively broad, flattened bodies, while Slipinskiini contains more elongate forms. Definitive identification to subfamily level requires examination of male genitalia and wing venation patterns.

Distribution

of Calochrominae occur across multiple continents. such as Calochromus and Lygistopterus have distributions spanning the Palearctic and Oriental regions. Macrolygistopterus and related genera occur in the Neotropics. The genus Aferos is known from Africa. Specific range boundaries for most species remain poorly documented.

ErotinaeAnother lycid , generally separable by body proportions and antennal ; Erotinae often exhibit more vivid aposematic coloration and different wing coupling mechanisms.
PlaterodinaeFemales of Platerodinae are and permanently wingless, whereas Calochrominae females are fully winged and similar in appearance to males.

Tribal classification

The is divided into two tribes: Calochromini (Lacordaire, 1857) containing the majority of , and Slipinskiini (Bocák & Bocáková, 1992) established more recently and containing the single genus Aferos.

Taxonomic uncertainty

counts vary between sources: Wikipedia cites 'more than 30 described species' while iNaturalist reports 'about 10 described species.' This discrepancy likely reflects ongoing taxonomic revisions and varying treatments of or synonyms.

Notable genera

Calochromus, the type , is the most -rich. Lygistopterus includes species with distinctive color patterns. Macrolygistopterus represents a primarily Neotropical radiation. Dumbrellia and Lucaina are smaller genera with restricted distributions.
