Intraspecific variation. Examined: 1♀, 5♂. Length: 11.7–13.7 mm (♂); fore wing length: 8.1–9.0 mm (♂).

Distribution. Morocco, Tunisia.

Remarks. Among the Palaearctic Pristaulacus , this new species is most similar to P. morawitzi , by the shape of the occipital carina and by the presence of only one tooth on the lateroventral margin of the pronotum. However, it can be distinguished by several characters reported in Table 5.

Biology. Hosts: Chlorophorus sexguttatus (Lucas, 1849) and Trichoferus cisti Sama, 1987 ( Coleoptera , Cerambycidae ).
