This document is the result of collaborative work among colleagues from different institutions in Mexico (Universidad de Quintana Roo, Cozumel and El Colegio de la Frontera Sur, Chetumal) and the United States (University of Texcas, El Paso). This work presents the taxonomy, morphology and distribution of the free-living, freshwater copepods that inhabit ephemeral aquatic habitats in one binational reserve known as the Chihuahuan Desert. This desertic zone is part of the large North American biogeographic region called Altiplano Mexicano, which is shared by Mexico and the United States. A joing effort was made to synthesize findings about the diversity of the copepods than inhabit this peculiar geographic area, where aquatic systems are scarce and ephemeral. It includes a taxonomic and morphological assessment of 33 copepod species and contains over forty individual drawings, and 37 plates of photographs of Scanning Electron Microscopy (SEM).

Resumen en inglés

Two new species of the freshwater copepod genus Eucyclops are described from two sites in the Chihuahuan Desert (CHD), which includes parts of northern Mexico and southern United States. Eucyclops cuatrocienegas sp. nov. is distinguished by having a short inner spiniform seta on the fifth leg, relatively short caudal rami, and a partially naked spine of the fourth endopod, among other characters. The finding of E. cuatrocienegas in Cuatro Ciénegas, an area in the CHD that is known for harbouring the highest number of endemic aquatic species in North America, suggests that these habitats could yield other endemic forms. The other new species resembles the Neotropical E. pseudoensifer Dussart, 1984 but differs in having a shorter basipodal spine of the first leg, shorter outer terminal spiniform caudal seta, a different length ratio of inner/outer spines of leg 4 third endopodal segment, and a different pattern of the serra on the caudal rami. Eucyclops pseudoensifer, originally collected from a high altitude lake in the Andean system of western Venezuela, is here redescribed from female and male type specimens. The description of E. chihuahuensis sp. nov. recognizes both the subtle but consistent differences of this population and its environmental isolation in this arid region. The North American records of E. pseudoensifer should be revised in the light of these findings in order to determine the real distributional ranges of these species.
