Remarks. This species was given the same name as a species described by Campbell and Clark (1944), but the two species are completely different. Lithomelissa robusta Campbell and Clark was transferred to Lithelius by Foreman (1968), long before Lithomelissa robusta Chen was described in 1975. Thus, Chen’s species name is valid because it is a secondary homonym; the two species were never congeneric at the same time.
