Recent studies of the genus Culicoides have exposed many new species and presented taxonomists with a difficult problem in using accepted characters or obtaining new differentiating characters clear-cut enough to provide suitable separation.
One such new character is the tibial comb, a structure found on the distal tip of the hind tibia of both sexes of ceratopogonid midges. Fox (1952) illustrated the tibial comb of several Puerto Rican Culicoides and (in litt.) suggested that this character might prove useful in separating other species of this genus. The present study appears to bear out this suggestion. Moreover the study indicates that the character might prove useful in other genera as well.
