Pristiphora krausi (Lacourt, 2006) new combination

Dinematus krausi Lacourt, 2006: 238-239. Holotype ♀ (MNHN, examined; images: https://doi.org/10.6084/m9.figshare.1157834.v1). Type locality: Saint Maurice-sur-Moselle (Vosges) [France, Lorraine].

Notes.

Pristiphora krausi is only known from the holotype. Its character combination of bifid claws, in dorsal view short and emarginate valvula 3, and yellow and black colour pattern of head and body, suggest that it may belong to the Pristiphora depressa group ( Prous et al. 2017). On the other hand, other currently known female specimens of this group have a mostly dark forewing vein C and pterostigma, whereas these are entirely pale in krausi . Furthermore, the distal sawteeth of krausi are prominently lobed, and markedly flatter in the other species. Pristiphora ifranensis Lacourt, 1973, only known from the male holotype (private collection of Thierry Noblecourt, examined), type locality Ifrane (Morocco, Middle Atlas), resembles krausi strongly in coloration, including its pale forewing vein C and pterostigma. Based on its penis valve morphology, ifranensis has been placed in the depressa group ( Prous et al. 2017). If further specimens become available for study, the possibility should be borne in mind that krausi and ifranensis represent the female and male of the same species.
