Synonyms and other taxonomic changes

Akalyptoischion has been recently moved to the family of its own(1)

Explanation of Names

Latridiidae Erichson 1842

Numbers

over 140 spp. in 16 genera in our area, ~1000 spp. in ~30 genera worldwide(2)(3)(4)(5)

Overview of our faunaTaxa not yet in the guide are marked (*)

Family Latridiidae

Subfamily Latridiinae Adistemia · Dienerella · Cartodere · Enicmus · Eufallia · Latridius · Metophthalmus · Revelieria · Stephostethus · Thes

Subfamily Corticariinae Corticaria · Corticarina · Cortinicara · Melanophthalma · *Fuchsina · Migneauxia

Size

0.8-3.0 mm

Identification

Tarsal formula 3-3-3, size 3 mm or less, and elongate-oval shape serve to separate this family(3)

Two subfamilies of rather different appearance:

Latridiinae: Body glabrous, or (rarely) with erect setae. Head, pronotum and elytra often with heavy sculpture dorsally (longitudinal grooves, ridges). Pronotal side margin usually smooth

Corticariinae: Body finely pubescent, hairs in most cases recumbent. Head, pronotum and elytra never with heavy sculpture dorsally, except for a subbasal circular pit or shallow transversal groove. Pronotal side margin often serrate

Range

worldwide; most diverse in temperate climates, in our area, most diverse in the west(3); several spp. (associated with stored products) are cosmopolitan(6)

Habitat

rotting vegetable matter; some species live in houses on damp wallpaper, moldy bread, etc. or otherwise associated with stored products.

Latridiinae are generally associated with leaf litter in nature(3)

Corticariinae can be collected by sweeping dead, low lying vegetation.

Season

Most prevalent during wetter seasons(3)

Food

fungal tissues (slime molds, molds, mildew, spores of "higher" fungi)

Remarks

Many taxonomic changes over the last two decades -- some quite confusing, with familiar names of genera often used in a different sense then before:

former Lathridius is now split into Cartodere, Stephostethus, Thes

several former Enicmus spp. are now Lathridius

former Cartodere are now Dienerella
