Etymology

This species is named ‘ boolei ’ after George Boole the self-taught English mathematician. The name is treated as a noun in the genitive sense.

Diagnosis

This species is distinct from all other species of Cremastobaeus due to the presence of a fully transversely striate frontal depression without any smooth walls.
