Descriptive notes. Length ca 11 – 12 mm, width of midbody metazonae 1.2 – 1.25 mm (male, female), metazonite to prozonite width ratio <1.7 ( Fig. 3A, 3H – 3J). Live coloration usually uniformly light brown, not reddish, about same as in alcohol ( Fig. 3A).

All characters as in P. abchasius ( Figs 3A, 3H – 3J, 4C, 4D), except as follows. Collum clearly narrower than head ( Fig. 3A, 3H). Paraterga not upturned, subhorizontal, mostly acute-angled and drawn behind rear tergal margin starting with segment 14 or 15 ( Fig. 3A, 3H – 3J). Gonopod ( Fig. 4C – 4D) with a shorter endomere rod and a less heavily spinulate exomere tip.

Remarks. Although the original description was clearly based only on the male ( Lohmander, 1936), the type series, “ Typen ”, actually consists of two specimens (male and female) which are to be considered as syntypes. To secure that the species is based on male material, the male is designated herewith as lectotype, the female as paralectotype.
