Laguna del Diario (34°54´S, 55°00´W) is proposed as the exact type locality of four species collected by Darwin during his stay in Maldonado.  (map and photos: P. Calviño, from publication)
This laguna is presumed to be the type locality of:  Australoheros facetus (Jenyns, 1842)
 Cheirodon interruptus (Jenyns, 1842)
 Cnesterodon decemmaculatus (Jenyns, 1842)
 Jenynsia lineata (Jenyns, 1842)

abstract (from publication): The famous English naturalist Charles Darwin (1809-1882) collected five species of freshwater fish in 1833 at the locality of Maldonado, Uruguay, between April and July of that year. Four of them: Australoheros facetus, Cnesterodon decenmaculatus, Jenynsia lineata and Cheirodon interruptus (described by Jenyns, 1842) were new for science. Until today, the locality type of these species was ambiguous with its precise location. In the present work it was determined that the lagoon “Laguna del Diario” (34° 54´ S, 55° 00´ W), in Maldonado, Uruguay, corresponds to the exact terra typica of these species. available at www.pecescriollos.de since 28.xi.2007 |
