Notes on type material. The type material consists of the holotype ♀ ( Semenow 1892a), which is in fair condition, but not well prepared. However, it lacks some parts: right fore tibia and tarsus; right last tarsomere. The body is covered with deposits.

Setae: segments 1 and 2 glabrous; recumbent, short, and moderately dense on following segments.

ď. Unknown.

Intraspecific variation. Examined: 1♀. Unknown.

Distribution. Turkmenistan.

Remarks. This species is known only by the holotype. As P. mourguesi Maneval and P. paglianoi Turrisi , sp. nov., it has a narrow and black occipital carina, one tooth on the lateroventral margin of pronotum and four teeth on the claw. The diagnostic characters are reported in tables 4–5. From P. longicornis , it is distinguished mainly by the smaller size, by the narrow occipital carina, rather than lamelliform, and by the shape of the pronotum and of the hind coxa.
