New and little known cladocerans (Crustacea: anomopoda) from southeastern Mexico
Mexico represents a transitional area in which two biogeographic regions meet. A survey of the cladocerans collected in true tropical waterbodies from the country revealed a diverse fauna. The environments examined included temporary pools in the forest, rivers, permanent lagoons and karstic sinkholes. New records or little known taxa include: Diaphanosoma brevireme, D. fluviatile, Pseudosida ramosa, Simocephalus mixtus, Onchobunops tuberculatus,Guernella raphaelis, Chydorus nitidilus, Notoalonacf. globulosa, Alonella brasiliensis and Leydigiopsis curvirostris. In contrast to high altitude systems, with clear nearctic affinity, the lowlands of southeastern Mexico showed a striking resemblance with the South and Central American cladoceran fauna. Apparently, orographic barriers control the distribution of the cladoceran taxa in this region.
