Motschulsky, 1859

Species Guides

Liothorax is a of scarab beetles in the Aphodiinae, historically treated as a subgenus of Aphodius. are characterized by elongate, parallel-sided to hemicylindrical bodies and distinctive lacking on the frontoclypeal . The genus comprises at least 16 Palaearctic species divided into niger and plagiatus species groups, plus additional species in the Nearctic and Neotropical regions. Recent revisions have used chromosomal analysis and molecular to clarify species boundaries.

Identification

Distinguished from related Aphodiinae by the combination of elongate body form and : specifically, the absence of on the frontoclypeal , clypeal margin, and bulging genae. Previously classified as Aphodius subgenus Liothorax; -level identification requires examination of male genitalia and chromosomal characters.

Appearance

Elongate, parallel-sided to hemicylindrical body shape. lacks on the frontoclypeal ; clypeal margin ; genae bulging. These morphological traits distinguish Liothorax from related Aphodiinae .

Habitat

Primarily associated with mud at the edges of pools and dried pool mud. Very rarely found in .

Distribution

Palaearctic region including Europe (England, France, Italy, Spain, Hungary, Slovakia, Czech Republic), Cyprus, Russia, Iran, and China. Also present in North America and Central America (Nearctic and Neotropical regions).

Diet

Saprophagous; adapted for saprophagy. consumption is extremely rare.
