Abstract: Earthworms are very important organisms, they are both environmentally and economically beneficial and hence their correct identification and classification is very vital. Taxonomy aims to classify organisms based on their similarities and differences. The present study was carried out during the year 2006-2007 at University of Guyana, Georgetown focusing on identification and classification of local earthworm species of Guyana and comparison with a known non-native species (California red). The earthworms were collected (using hand sorting method), cultured and then carefully examined (worms were washed with water, preserved in 10% formalin solution). The two species studied were identified based on their external morphology and internal anatomy as well as their ecological features. The California red earthworm was grouped under the family Lumbricidae and identified as Eisenia foetida, while the local species was grouped under the family Eudrilidae and identified as Eudrilus eugenia.
