and impunctate. Microsculpture, underside, and legs as in P. se/kirkz, but the 
metepisterna are only a third longer than wide, and the dilated apical part of 
the metetibiae is only a half wider than the basal part. 
In this species, as in the two preceding ones, the outer striae of the elytra 
converge and become very narrow behind; as in the genus Adax, there is a 
ridge, though a slight one, in the marginal channel of the elytra behind, and 
as in Zapinopterus the hind lateral seta of the prothorax is (apparently) wanting,
