RODRIGUEZ-SERNA, Miguel; CARMONA-OSALDE, Claudia; ARREDONDO-FIGUEROA, José Luis y OLVERA-NOVOA, Miguel A.. Present geographic distribution of Procambarus (Austrocambarus) llamasi (Cambaridae) from Yucatan Peninsula. Hidrobiológica [online]. 2002, vol.12, n.1, pp.1-5. ISSN 0188-8897.
There are two species of astacids of the genus Procambarus reported for the Yucatan Peninsula: Procambarus pilosimanus (Villalobos, 1955) and Procambarus llamasi (Villalobos, 1955). P. pilosimanus was only found in Quintana Roo, while P. llamasi is present from south Veracruz to Campeche. This research was carried out with 129 collecting sites to determine P. llamasi distribution in the three states of the Yucatan Peninsula. In the present study P. llamasi was also found in Quintana Roo, but P. pilosimanus was not collected in any of the sampling sites. At the northern region of Yucatan and Quintana Roo small number of organism were collected as it is a karstic area. High number of organisms were easily found in the south part of Yucatan Peninsula where less permeable soils exist. The distribution of P. llamasi depend on the rainy season (July - October). It was difficult to collect them during the dry season (January- June) as part of its burying adaptation made it hard to found.
