D i a g n o s i s: The genus Perilypus SPINOLA was revised in 1977 (EKIS 1977). This work included a key to species. The available Perilypus virgulatus specimens key out to P. distinctus EKIS, from which P. virgulatus specimens differ by showing a phallobasic lobe that is not uncinate.

Head: Interocular depression shallow, crescentic; frontal umbo not prominent; cranium minutely punctate; antenna (Fig. 11) moderately serrate, not densely setose, antennomeres gradually increasing in diameter from scape to antennomere 11; eyes finely facetted, eye narrower than frons (EW/FW 25/40).

E t y m o l o g y: Thetrivialname, virgulatus, is a Latin adjective with a meaning of "stripes"; in reference to the vitta on the elytral disc.
