Taxonomic revision of the Mexican Eucyclops (Copepoda: Cyclopoida) with comments on the biogeography of the genus

Taxonomic revision of the Mexican Eucyclops (Copepoda: Cyclopoida) with comments on the biogeography of the genus

Based on the examination of specimens deposited in different national and international biological collections, we reviewed the ca. 800 records of the genus Eucyclops in Mexico and compared them with the type material of presumedly widespread species. Resulting from our taxonomical analysis, in this contribution we recognise 17 species dwelling in Mexico. Complementary upgraded descriptions of eight species emphasising newly introduced taxonomic characters are also presented from the examination of Mexican specimens. These species include E. elegans, E. prionophorus, E. festivus, E. leptacanthus, E. torresphilipi, E. chihuahuensis, E. cuatrocienegas and the recently described E. tziscao and E. angeli. In addition, the use of upgraded descriptive standards involving new morphological characters allowed the discovery of six new species that are described in thiswork: E. alekseevi sp. nov., E. wixarica sp. nov., E. defayeae sp. nov., E. mittmanni sp. nov., E. estherae sp. nov. and E. ishidai sp. nov. Most of these species were previously recorded in Mexico under different names. The occurrence of E. pectinifer, E. elegans, E. prionophorus and E. leptacanthus in Mexico is herein confirmed. We propose the ornamentation patterns of the fourth swimming legs (i.e. basipodite, coxal plates) as reliable additional characters to recognise closely related species of Eucyclops.
