Abstract
A total of 15 taxa of aquatic oligochaetes have been identified in two collections, one of which was from Coiba island, at the National Museum of Natural Sciences (MNCN, Madrid), and the other from Cuba (leg. Dr. Ana Camacho). Morphological and systematic remarks are provided for Limnodrilus variesetosus, Pristina aequiseta forms evelinae and foreli, P. breviseta, P. osborni, and P. sima. Pristina cabacuensis Botea, 1983 and P. decui Botea, 1987 are proposed as junior synonyms of Pristina aequiseta Bourne. The taxonomy of Pristina osborni and P. sima is discussed and their independent specific status supported. The alluroidid Brinkhurstia americana is reported from Coiba island widening the known geographical distribution of the species to South and Central America.
Highlights
In the present work, new data from two collections of oligochaete worms from both hyporheic and running waters in Coiba island and from subterranean waters in Gibara, Cuba, are provided
The author stated that the most significant difference of the species is the length of the needle teeth which is described as long; their length is only 0.5 μm, (c) Sociedad de Amigos del Museo Nacional de Ciencias Naturales y Consejo Superior de Investigaciones Científicas Licencia Creative Commons 3.0 España http://graellsia.revistas.csic.es they are very short
The freshwater oligochaete fauna of Central America and the Caribbean region has been previously studied by several authors
Summary
New data from two collections of oligochaete worms from both hyporheic and running waters in Coiba island and from subterranean waters in Gibara, Cuba, are provided. REMARKS: Among the American Limnodrilus species, both L. variesetosus Brinkhurst, 1979 and L. rubripenis Loden, 1977 show enlarged ventral chaetae with very long upper teeth in some segments of the anterior part of the body.
