Subgenus Randallius Bousquet, n.subg.

Randallius Bousquet, n.subg. Type species: Chlaenius purpuricollis Randall, 1838. Etymology. The generic name is proposed in honor of John Witt Randall [1813-1892] who in his 20s published two descriptive papers on the beetles of Maine and Massachusetts. One of his new species is the type species of this subgenus. Randall did not publish anything else on entomology after these two papers but wrote a volume of poems in 1856 entitled "Consolations of Solitude." His collection is lost (Sprague 1875: 374). The gender of the name is masculine.

Diversity.

One North American species.

Taxonomic Note.

In my opinion, Chlaenius purpuricollis is taxonomically isolated and within the actual structure of the genus Chlaenius deserves to be placed in its own sub genus. See Bell (1960: 135) and Lindroth (1969a: 994) as " purpuricollis group" for the descriptive character states of this new taxon.
