Abstract

Cochimibdella mexicana n. gen. n. sp. is described based on morphological data and comparative analysis of DNA sequences, including two mitochondrial (cytochrome oxidase subunit I and 12s rRNA) and nuclear (18S rRNA and 28S rRNA) loci. Leech specimens were found in the mantle cavity and external surface of the octopus Octopus bimaculatus from Bahía de los Ángeles, Baja California, México. In vivo observations of recently hatched leeches in the laboratory confirm a broad prey range, including fishes, the most common hosts of the family species. The new taxon differs from species of the family Piscicolidae in possession of weakly developed tubercles in a3 of the urosome. In addition, molecular analysis places Cochimibdella mexicana n. gen. n. sp. sister to Austrobdella californiana and Myzobdella lugubris. This work amends a previous record of the elasmobranch-feeding leech Pontobdella (=Stibarobdella) moorei as a parasite of Octopus bimaculatus from the type locality of the new taxon.

期刊介绍： Systematic Parasitology publishes papers on the systematics, taxonomy and nomenclature of the following groups: Nematoda (including plant-parasitic), Monogenea, Digenea, Cestoda, Acanthocephala, Aspidogastrea, Cestodaria, Arthropoda (parasitic copepods, hymenopterans, mites, ticks, etc.), Protozoa (parasitic groups), and parasitic genera in other groups, such as Mollusca, Turbelleria, etc. Systematic Parasitology publishes fully illustrated research papers, brief communications, and fully illustrated major revisions. In order to maintain high standards, all contributors describing new taxa are asked to state clearly where the holotype is deposited and to make paratypes available for examination by the referees. It is recognized that, in some cases, this may cause problems for the authors, but it is hoped that by adhering to this rule authors may be protected against rapid synonymy of their taxa, and the types will be preserved for posterity.
