3A82BCD0504A5284A9AF94CDCC333344.taxon	diagnosis	Diagnosis. This genus is similar to Atrachya Chevrolat, 1836 and Monolepta Chevrolat, 1836. In Paleosepharia, the third antennomere is longer than the second (both antennomeres are more or less equal in Monolepta), and the epipleuron continues towards the apex (suddenly narrowed before the middle in Monolepta), procoxal cavity is closed behind (opened in Atrachya). Male genitalia. In Paleosepharia and Atrachya the aedeagus is parallel-sided in the basal two-thirds, apical third strongly narrowed (aedeagus slender, parallel-sided in Monolepta). In Paleosepharia, tectum long, rounded or truncate at apex (rounded at apex in Monolepta; incised at apex, the two apical tips forming strong hooks in Atrachya). Paleosepharia usually has two pairs of strongly sclerotized spiculae (lateral and median), while the ventral spiculae are weakly sclerotized. The median spiculae consist of long, slender spikes.	en	Feng, Chuan, Yang, Xingke, Ge, Siqin (2025): Two new species and two new combinations within Paleosepharia (Coleoptera, Chrysomelidae, Galerucinae) from China.
