Diagnosis.

P. mourguesi is one of the largest species among the Palaearctic Pristaulacus with a body length varying from 16.5 to 18.5 mm (excluding ovipositor), and fore wing length of 8.8-13.0 mm (♀). It is distinguished by the shape of the head, narrow cerciniform occipital carina (width 0.2 × ocellus diameter), hind basitarsus long and slightly curved, 1.5 × length of tarsomeres 2-5, and long ovipositor, 1.4-1.6 × fore wing length.

Morphometric ratios.

Hosts.

Unknown ( Turrisi 2007).

Remarks.

This species was previously recorded only from Europe ( Turrisi 2007, 2013a). There is a possible record for the Near East without source material ( Madl 2012). The closest species is P. morawitzi (Semenow, 1892) being medium sized, punctures of head very fine, superficial, and scattered, metasoma pyriform, strongly compressed, nearly entirely reddish orange. See Turrisi (2007) for more details.
