Abstract
During zooplankton surveys carried out between 1987 and 1991 oV the northern coast of the Yucatan Peninsula, southeast Mexico, several monstrilloid copepods were collected. Three species were identified: Cymbasoma chelemense Suárez-Morales and Escamilla, 1997, C. quintanarooense (Suárez-Morales, 1994) and a new species of Monstrilla. Cymbasoma quintanarooense was described from the western Caribbean Sea a few years ago; new and complementary morphological data are added to the original description of this species. Previous to this survey, only one specimen of Cymbasoma chelemense, the holotype, had been collected; an additional specimen is recorded here from the type locality for this species. Monstrilla humesi sp. nov. is described following a set of recently proposed standards for the description of monstrilloid copepods. The new species is quite similar to M. helgolandica Claus, 1863 and to M. gracilicauda Giesbrecht, 1892a. It can be distinguished by the presence of a bilobed fifth leg, the position of the oral papilla, and by the proportional length of its genital compound somite.
