Dorsal multilocular disc pores present across posterior edges of abdominal segments IV–VII, and laterally on segments II and III; also on venter, across posterior edges of abdominal segments II–VI, and anterior and posterior edges of segment VII, and posterior to vulva. Quinquelocular pores absent. Trilocular pores evenly dispersed. Discoidal pores minute, scattered. Dorsal oral collar ducts of 1 size, present across head, thorax and abdominal segments; also on venter, where of 2 sizes: large type as on dorsum, scattered on thorax and margins of abdominal segments, and a small type present medially on posterior abdominal segments.

DISTRIBUTION. Palaearctic: Armenia, Bulgaria, Caucasus, China, France, Georgia, Iran, Kazakhstan, Mongolia, Russia, Tajikistan, Turkey, Turkmenistan and Uzbekistan. In Iran, P. p u m i l u s occurs in Bushehr, Markazi and Yazd. P. pumilus is known from 21 plant families worldwide (Ben-Dov et al., 2012).
