CYCLOPINAE Kiefer, 1927


ALLOCYCLOPS Kiefer, 1933


The genus Allocyclops has beeen recently revised by Karanovic (2001) who subdivided it into three subgenera, viz. Allocyclops Kiefer 1932 s.str., Psammocyclops Kiefer 1955 and Stolonicyclops Reid & Spooner 1998

Moreover, Karanovic (2001) included in the genus Allocyclops also the species Speocyclops orcinus Kiefer, 1937 as Allocyclops (s.str.) orcinus (Kiefer, 1937) and Bryocyclops arenicolous (Fryer, 1956) as Allocyclops (s.str.) arenicolous (Fryer, 1956).

The genus Allocyclops is widespread on all continents, except Antartica. The subgenus Psammocyclops shows Gondwana connections, its species being distributed in S. America, Madagascar, Africa and Australia (left: A. consensus).

    APOCYCLOPS Lindberg, 1942


    The genus Apocyclops Lindberg, 1942, formerly described as a subgenus of Cyclops, occurs in brackish water bodies (coastal lagoons, bays, estuaries, pools, caves, lakes in desert areas), most species coming from tropical and subtropical regions. The following species have been accepted as valid: A. borneoensis, A. dengizicus, A. dimorphus, A. distans, A. japonensis, A. panamensis, A. procerus, A. royi and A. spartinus. The species A. dimorphus (Kiefer, 1934) is questionable.

    * Lepeschkin (1900) described Apocyclops dengizicus as Cyclops diaphanus var. dengizica to accomodate material from brackish waters of the lake Selety-Tengiz (Kazakstan). Kiefer (1926) raised it at specific level, and later on Lindberg (1942, 1954) attributed it to the genus Apocyclops. Recently Mirabdullayev & Stuge (1998) redescribed the species on material from Kazakstan and Uzbekistan, reporting as well data on its variability and distribution in central Asia.

    Knott & Jasinska (1998) reported this species from Australia as Microcyclops dengizicus.

    Other synonyms are: Apocyclops buxtoni (Gurney, 1921) and Apocyclops dimorphus (Kiefer, 1934) (Dussart & Defaye, 1985); Herbst (1984) considered A. buxtoni and A. dimorphus as valid taxa. Gurney (1921) described Cyclops buxtoni from the Tigris River, Amara (Iraq), later renaming it Cyclops dengizicus when he discovered this species in brine pools at Kabret and in bitter pools of Lake Timash (Egypt). According to Arnofsky (in litt.) it is possible that C.buxtoni could be synonym of Apocyclops royi Lindberg, 1940.
