| Sumario: | [EN] The author updates the knowledge on the genus Oxytrechus Jeannel, 1927, as a result of the study of the material belonging to the Biosystematic Research Centre of Ottawa (Canada), and also to the collections in Ecuador by Pierre Moret from Paris. This genus of Carabidae increases now with nine new species from Colombia and Ecuador which, added to the previously described give a whole of twenty species presently known. The new species are: O. caucaensis, O. solitarius, O. silvianus, O. bousqueti, O. campbelli, O. jeanneli spp. n., all of them from Colombia, and O. globosas, O. guaguanus and O. convexus spp. n. from Ecuador. The species of Oxytrechus are distributed as follows: 10 species from Ecuador, 7 from Colombia, 1 from Peru, 1 from Chile and 1 from Uruguay-Argentina, which is then the most meridional one. The group is quite homogeneous, and the species differ specially by the characters of the aedeagus. The differences concerning the external morphology are rather weak. Therefore, two keys for species identification are provided: one based on the external morphology, and the other on the characters of the aedeagus. Almost all the species (excepting O. arechavaletai (Putzeys), from Uruguay, and O. fasciger (Putzeys), from Peru) were collected on the Andes «páramo» at altitudes between 3,200 and 4,800 m. a.s.l. |
