| - According to ASHE & O'CONNOR (2009), SiETHER & SPIES (2013), the genus Potthastia Kieffer, 1922 is represented worldwide by four species: P. gaedii (Meigen, 1838); P. longimanus Kieffer, 1922; P. montium (Edwards, 1929) and P. pastoris (Edwards, 1933). The male and female imagoes and the pupal exuviae of the four latter Potthastia species are examined and reviewed, based on a large material collected in Corsica and continental France between 1975 and 2015. Additional material composed of stored slides previously collected between 1980 and 1997 in Lebanon and Algeria is also studied that enriched our knowledge and updated the list of known Potthastia species from these two countries. In this paper a description of three new species (P. dominicii sp. n., P. giudicellii sp. n., P. valserina sp. n.) is provided based on a material recently collected in the rhithral of some pristine permanent low mountain streams and rivers respectively located in western Corsica, the Pyrenees and the Jura Massif. While P. dominicii sp. n. and P. giudicellii sp. n. are described as male and female adults and pupal exuviae, only the description of the male adult of P. valserina sp. n. is provided. Male imaginal and pupal characters of P. dominicii sp. n. are quite similar to those of P. gaedii. Based on some features found in the male adult of P. giudicellii sp. n. this new species is keyed near P. montium. The male adult of P. valserina sp. n. is keyed near P. gaedii and P. longimanus. While P. dominicii sp. n. is known from both Corsica and the Pyrenees, the geographical distribution of P. giudicellii sp. n. is apparently restricted to the western Province of Corsica. P. valserina sp. n. is only known from its type locality, which is situated in the Valserine karstic stream (Jura Massif). Consequently, the description of P. dominicii sp. n., P. giudicellii sp. n. and P. valserina sp. n. increases the total number in the genus to six for Corsica and continental France. Currently, there are three Potthastia species known from Lebanon (P. gaedii, P. longimanus and P. pastoris) and only two from Algeria (P. gaedii and P. pastoris). Additional material, obtained more recently from Corsica, continental France and Lebanon revealed the presence of three more undescribed species including two distinct new morphotypes (P. sp. 1 and P. sp. 2, gaedii-group) and one other distinct male adult labelled as P. sp. 3 (montium-group). The first morphotype (P. sp. 1) is known from Corsica, the Pyrenees and the Maritime Alps, while the second (P. sp. 2) is reported from Lebanon. The male adult of P. sp. 3 is only known from Corsica. Therefore, the recent updated list of 740 species provided by MOUBAYED-BREIL & ASHE (2016) on the Chironomidae of continental France, is currently upgraded to 742 known valid species, which actually include the two new species P. dominicii sp. n. and P. valserina sp. n. For each of the seven currently known valid Potthastia species mensural features and main distinguishing characters of the male adult and pupal exuviae are provided in Tables I (male adults p. 35) and II (pupal exuviae p. 36) which can supplement and correct some previous data from the literature. Taxonomic Remarks on some related species with key to male adults and pupae, discussion and comments on the ecology and geographical distribution of the new species are provided.
