Remarks

The knowledge of the genus Metacyclops in the Nearctic region is limited, the genus is considered as tropical and temperate, with around 52 species and subspecies worldwide; currently up to 26 species of Metacyclops have been recorded in the Americas ( Reid 1991), but only Metacyclops cushae , Metacyclops gracilis Lilljeborg 1853 , and Metacyclops cf. campestris have been confirmed as valid records in the Nearctic region ( Mercado-Salas 2009). Metacyclops cushae was described upon specimens from southeastern USA ( Louisiana), hence this record extends the distributional pattern of the species, and confirms that the number of Cyclopinae genera recognized in Mexico has increased to 10 (see Elías-Gutiérrez et al. 2008) including the record of Metacyclops cf. campestris in Coahuila, México ( Mercado-Salas 2009).
