    PSAMMOPHILOCYCLOPS Fryer, 1956

    In the genus Psammophilocyclops, four species are at preent recognized: P. boccaroi Fryer, 1956 from Africa, P. trispinosus Shen et Tai, 1964. P. paucisetosus Lee & Chang, 2011 and P. bispinosus Shen et Tai, 1964 from China. They are all hypogean, considering that all the members were reported from the interstitial waters of lakeside or riverside sand beaches, and that they usually co-occurred with species of the genus Parastenocaris, one of the most representative interstitial copepods (see Lee and Chang, 2009: 169).


  • Psammophilocyclops boccaroi Fryer, 1956 [Africa, Malawi; fresh waters]
  • Psammophilocyclops bispinosus Shen & Tai, 1964 [China; fresh waters]
  • Psammophilocyclops paucisetosus Lee & Chang, 2011 [Korea; fresh waters]

    RHEOCYCLOPS Reid & Strayer, 1999

    "Diacyclops virginianus Reid, 1993, from Goose Creek, Virginia, was tentatively placed in the genus Diacyclops by its author. The fifth leg of D. virginianus, with the proximal segment reduced to a small knob fused to the somite, and two setiform terminal appendages on the distal segment, does not conform to the usual condition in Diacyclops. Pesce (1994) observed correctly that assignment of D. virginianus to the genus Diacyclops confused the status and definition of the genus, although he then designated this species as the type of his "Diacyclops virginianus-group." Following the discovery and analysis of four additional species similar to D. virginianus, from hyporheic zones of streams and a drip pool in a cave in the southeastern and central U.S.A., Reid et al, 1999 propose to separate these in the new genus Rheocyclops"

  • Rheocyclops hatchiensis Reid & Strayer, 1999 [USA; hyporheic]

    TERATOCYCLOPS Plesa, 1981

    As regard this inadequately characterized, monospecific genus, long since Dussart & Defaye (1985) pointed out its incomplete description and illustrations; later on Reid (1993) too remarked the absence of adequate figures in Plesa's description, hypothesizing as well that both segments of leg 5 could be distinct in this genus. Nevertheless, recent re-examination of the type material (Plesa, in litt.) revealed that the nominate leg is composed of a single free segment and confirmed the taxonomic validity of Teratocyclops.

    More recently, Iepure & Defaye (2003) redefined the genus, giving the following distinctive characteristics: 11-segmented antennule, presence of vestigial exopodite on the antenna, structure of the distal segment of the endopodite of leg P4 with 1 spine and 3 setae, and the proximal segment of leg 5 fused to the somite. The relationship to the closely related genera Metacyclops Kiefer, 1927, Apocyclops Lindberg, 1942, and Goniocyclops Kiefer, 1955 are also discussed by the same authors.

    "Some other genera of the family Cyclopidae share with Teratocyclops the following morphological characters of the P5 and the antennule: on P5, the proximal segment having the proximal segment completely fused with the somite and represented by a long seta, and the distal (free) segment ending with 2 setae or spines; the female antennule 10- or 11-segmented. These genera are: Metacyclops Kiefer, 1927 sensu Lindberg, 1961, Muscocyclops Kiefer, 1937, Apocyclops Lindberg, 1942, Menzeliella Lindberg, 1954, Goniocyclops Kiefer, 1955, Cochlacocyclops Kiefer, 1955, Hesperocyclops Herbst, 1984, Fimbricyclops Reid, 1993, and Rheocyclops Reid & Strayer, 1999 (in Reid et al., 1999). Among these genera, seven have the same biarticulate structure of the swimming legs: Fimbricyclops, Muscocyclops, Apocyclops, Menzeliella, Metacyclops, Goniocyclops and Cochlacocyclops. Hesperocyclops has the endopodite of P4 unisegmented (Herbst, 1984; Rocha & Bjornberg, 1987) and Rheocyclops has P1 to P4 basically tri-segmented, with some species with bi-segmented rami (Reid et al., 1999)" (from: Iepure & Defaye, 2003)

    PSAMMOCYCLOPS Kiefer, 1955

    "Psammocyclops is distinct among the three genera characterized by the leg 5 with the vestiges directly inserted on the pedigerous somite. The ventral position of the vestiges representing the ancestral distal segment in Psammocyclops and their location at a remote distance from the lateral ancestral basal segment vestige is in sharp contrast with the noticeable lateral position of the three remnant elements in Stolonicyclops and Virbiocyclops. The position and differentiation of the leg 5 in Olmeccyclops is comparable" (from: Fiers, 2011)
