Ceroputo nulliporus (McKenzie) comb. nov.

Puto nulliporus McKenzie, 1960: 733 .

This species is known only from the original collection on Bebbia juncea var. aspera (Asteraceae) from near Palo Verde, and on Encelia farinosa (Asteraceae) from Glamis, both in Imperial County, California, U.S.A. The placement of this species was regarded as doubtful by Williams and Granara de Willink (1992). Character states that exclude this species from Puto are the campaniform sensilla on the trochanters are always two in number on each surface, the antennal intersegmental sensilla are tiny and present only between segments VI and VII, there are no multilocular pores, and the trilocular pores in the cerarii are the same size as those on the rest of the derm. Character states that it shares with species of Puto are the possession of basal spurs on the claw, although the spurs on C. nulliporus are thin and very poorly developed. Despite some conflicting evidence, we conclude that this species does not belong to Puto and transfer it to Ceroputo .
