Sternite 10 with 1 seta on each half. Distribution. China (Yunnan, Fig. 24). Remarks. By its setose M and Cu, slightly elongated necks and setae on the flagellomeres and the form of the gonostylus, the new species is most similar to P. crassidens Hippa & Vilkamaa, 1991. However, they may be distinguished by three longer megasetae on the dorsal lobe on a parallel-sided gonostylus in P. columellata, while more than three megesetae on a slightly inflated gonostylus in P. crassidens. Etymology. This species is named after its parallel-sided gonostylus, which looks like a pillar, from the Latin adjective columellatus, meaning pillar.
