Records from literature. Kieffer (1906, 1912).

Type locality. “ Espagne, environs de Barcelone” ( Kieffer 1906) .

Notes on type material. The type material was not found by Oehlke (1983), and I was unable to locate it. Its depository was not indicated in the original description ( Kieffer 1906).

Description. ♀ (according to Kieffer 1906: 120). Length (excluding ovipositor): 11.5 mm.

Colour black except: median part of metasoma and hind margin of following segments, red; distal part of fore and mid femora and fore tibia and tarsus rust red; mid and hind tibiae and tarsi dark brown; pronotum with a tooth on the posterior part of lateroventral margin; median lobe of mesoscutum not rope-shaped; fore wing with a brown spot behind stigma, occupying apical part of SM1 and base of SM2, and three other small brown spots, one on apical part of SD, one on second transverse discoidal vein and one on apex of wing; hind wing with some weak veins, poorly visible, closing two basal cells; hind basitarsus weakly shorter than tarsomeres 2–5; claw with four teeth; ovipositor entirely black, much longer than body.

ď. Unknown.

Intraspecific variation. Unknown.

Distribution. Spain.

Remarks. According to Kieffer (1906), P. proximus is most similar to P. compressus (sub P. schlettereri ). The diagnostic features are the absence of the anterior tooth on lateroventral margin of the pronotum, and the presence of a posterior tooth instead; other differences are represented by the sculpture of the median lobe of mesonotum, without longitudinal groove, and the hind basitarsus shorter than tarsomeres 2–5. From our current knowledge it is not possible to clarify the identity of P. proximus , and to confirm its specific validity.

Biology. Unknown.
