Abstract
We describe two new species of the earthworm genera Holoscolex and Glossodrilus from the Gurupi Biological Reserve, Maranhão State, Brazil. This reserve represents one of the last wild refuges of the Belém Endemism Area, the most deforested and threatened region of the Brazilian Amazon. Holoscolex contractilissp. nov. belongs to a selected group of this genus characterized by intraclitellar atrial glands, and it is unique in having two pairs of spermathecae in segments 7 and 8, with atrial glands adjacent in 8 and 9, and free testes in segment 11. Glossodrilus rubrasp. nov. remains among the Glossodrilus species with two pairs of spermathecae in segments 8 and 9, but differs from its congeners by the position of the spermathecal openings in CD line and aquadrangular body at tail.
期刊介绍：
Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
