Pachylocerus corallinus is a species of beetle in the family Cerambycidae. It is found in southwestern India. It was first described and given its binomial name by Frederick William Hope who examined a specimen from the cabinet of Captain Thomas Smee of the Indian Navy who had obtained it from a prickly pear in the vicinity of "Omlecope Dawar" (possibly "Ontikoppa" near Dharwad).[1] Specimens have been recorded from as far north as Bombay, south through Matheran, Goa, to Mangalore.[2] In this genus, the eyes are divided. The antennae are short and do not reach past the middle of the elytra in the male and are even shorter in the female.[3]
