Subfamily Chydorinae Dybowski et Grochowski, 1894

74. Alonella excisa (Fischer, 1854), recorded by Gauthier (1928a), Dumont et al. (1979), Samraoui et al. (1998) and in this study (sites 5, 55, 65, 66). Cosmopolitan species complex ( Smirnov 1996) with probably more than one species in the tropics ( Kotov et al. 2013b).

75. Chydorus sphaericus (O. F. Müller, 1776) s. lat., recorded by Gurney (1909), Gauthier (1928a), Dumont (1979), Dumont et al. (1979), Samraoui et al. (1998) and in this study (sites 12, 14, 29, 30, 34, 37, 38, 55, 56, 61, 64, 65, 68, 73, 79, 82, 98, 101, 103, 106). Recent genetic investigations of C. sphaericus complex ( Belyaeva & Taylor 2009; Kotov et al. 2016) have revealed a number of sibling species within the Palearctic region, which can be recognized either by morphology of males and ephippial females, or genetically. The taxonomic status of Algerian populations needs to be clarified.

76. Dunhevedia crassa King, 1853, recorded by Gauthier (1928a, 1931, 1934), Samraoui et al. (1998), Samraoui (2002) and in this study (site 34). It is distributed “worldwide, at warm latitudes” ( Smirnov 1996) and in need of a taxonomical revision ( Van Damme et al. 2013b).

77. Ephemeroporus barroisi (Richard, 1894) , recorded as Chydorus barroisi by Gauthier (1928a, c), Dumont (1979) and Samraoui et al. (1998). A complex of Ephemeroporus species was revealed to be present in the Mediterranean region ( Frey 1982; Alonso 1987); the taxonomic status of Algerian and other populations needs to be clarified ( Kotov & Ferrari 2010).

78. Ephemeroporus phintonicus (Margaritora, 1969)*, recorded by Frey (1982) referring to Gauthier's (1928a) description of E. barroisi from the Réghaia area (Algiers province). It is a species limited to the Mediterranean region ( Frey 1982).

79. Picripleuroxus laevis (Sars, 1862)*, recorded by Gauthier (1928a), Dumont et al. (1979) and Samraoui et al. (1998). Palearctic species, similar forms occur in Australia ( Smirnov 1996) and tropical Africa ( Chiambeng & Dumont 2004).

80. Pleuroxus aduncus (Jurine, 1820)*, recorded by Gurney (1909), Gauthier (1928a, 1929, 1931), Dumont (1987), Samraoui et al. (1998), Samraoui (2002) and in this study (site 52). Cosmopolitan species complex ( Kotov et al. 2013a). The populations studied here belong to P. aduncus s. str. instead of some other taxa revealed in other African countries ( Smirnov et al. 2006; Smirnov 2007, 2008).

81. Pleuroxus letourneuxi (Richard, 1888)*, recorded by Blanchard (1891), Blanchard & Richard (1890, 1891), Gurney (1909), Gauthier (1928a, 1934), Dumont (1979) and in this study (sites 9, 20, 24, 68, 73, 88). This taxon was described from Tunisia, see comments in Kotov & Ferrari (2010). West Mediterranean species ( Smirnov 1996).
