On a small collection of Laophontidae T. Scott (Copepoda: Harpacticoida) from Mexico. II. New records of Quinquelaophonte Wells, Hicks and Coull and description of Onychoquinpes permixtionis gen. nov. et sp. nov.

Abstract

A number of new species and new records of harpacticoid copepods have been published in the last 14 years in an effort to achieve a better knowledge of the Mexican harpacticoid fauna. This is the second contribution dealing with the description and new records of species of the family Laophontidae collected in 1991 from central and southern Sinaloa State (north-western Mexico) and from the Gulf of Mexico. In this contribution, new illustrated records of Quinquelaophonte quinquespinosa (Sewell) and Quinquelaophonte capillata (Wilson) are provided. Also, a new genus and species, Onychoquinpes permixtionis gen. nov. et sp. nov. is described. The new genus and species herein proposed exhibits a unique mixture of character states typical for Onychocamptus Daday and Folioquinpes Fiers and Rutledge; so the erection of a new genus is justified. http://www.zoobank.org/urn:lsid:zoobank.org:pub:2F77DCEA-37EE-428C-9E84-1F518F77512C
