Malandryinae

Malandryinae can be distinguished from other tenebrionoid subfamilies by the combination of: pronotum with distinct lateral margins; antennae with 11 segments and a weakly to moderately clubbed apex; tarsal formula 5-5-4 in most genera; and elytra often with distinct striae or costae. The body form ranges from moderately elongated to somewhat flattened, unlike the more cylindrical form of many Lagriinae.

Primarily saproxylic, associated with dead and decaying wood in forest ecosystems. Found in mature and old-growth forests where standing dead trees and coarse woody debris persist. Some species occupy specific decay stages or wood types (hardwood versus conifer).

Holarctic distribution with primary centers in temperate Europe, Asia, and North America. Present across boreal and temperate forest zones; absent from tropical regions and the Southern Hemisphere.

Saproxylic decomposers facilitating nutrient cycling in forest ecosystems. Larvae tunnel in decaying wood, contributing to structural breakdown and creating habitat for other invertebrates. Part of the complex community of organisms dependent on dead wood continuity in forests.

Indicator taxon for forest continuity and habitat quality in conservation assessments. Presence and abundance used in European forest biodiversity monitoring programs. No significant economic impact; neither pest nor beneficial species in agricultural or forestry contexts.

• LagriinaeOverlapping family-level classification historically; distinguished by more cylindrical body form, stronger sexual dimorphism in antennae, and different larval habitat preferences (often soil or litter rather than wood).
• TenebrioninaeSimilar general appearance but distinguished by different tarsal formula (often 5-5-4 versus variable), different antennal club structure, and primarily non-saproxylic habits.
