Latridiinae is a of minute beetles within the Latridiidae, first described by Erichson in 1842. The subfamily contains at least 18 recognized distributed globally, including economically significant genera such as Latridius, Enicmus, Dienerella, and Stephostethus. Members are among the smallest beetles, often overlooked due to their size and cryptic habits. Taxonomic research continues to reveal new , particularly in underexplored regions such as Taiwan and Central Asia.

Identification

Latridiinae are distinguished from other Latridiidae by genital segment structure and subtle morphological characters of the , which are frequently used in -level diagnostics. Members are minute (typically 1–3 mm), with compact bodies and often punctured or sculptured . The subfamily can be separated from other Coccinelloidea by the combination of small size, antennal club structure, and tarsal formula.

Habitat

Specific preferences for Latridiinae as a are poorly documented. Available records indicate collection from forest floor litter, decaying vegetation, and fungal substrates. The Stephostethus has been recorded from Taiwan in association with forested habitats, though detailed microhabitat data remain limited.

Distribution

distribution with records from the Palaearctic, Nearctic, Oriental, and Australasian regions. The Stephostethus extends to Taiwan at the southern boundary of its Palaearctic range. The genus Dienerella contains 41 described globally, with 15 demonstrating regional diversification patterns.
