Gerris (Gerris) maculatus Tamanini, 1946 *

Material examined. Safsaf, 0 1.0 3.17, 1 m, 1 f.

Distribution. West Palearctic species. In Morocco, it is probable that G. maculatus has been frequently confused with G. gibbifer Schummel, 1832 (Berchi et al. 2018a); thus, a review of the records citing the latter species should be performed to confirm its presence in Morocco and to improve the knowledge of the distribution of G. maculatus in this country. In the study area, G. maculatus was previously cited at Taforalt spring (Chavanon et al. 2004) as G. gibbifer . During the sampling period of this study, G. maculatus was found at Lower Moulouya (Fig. 3).
