Abstract
FIKACEK, Martin. Occurrence of introduced species of the genus Cercyon (Coleoptera: Hydrophilidae) in the Neotropical Region. Rev. Soc. Entomol. Argent. [online]. 2009, vol.68, n.3-4, pp.351-357. ISSN 0373-5680.
The occurrence of the species of the genus Cercyon Leach introduced to the Neotropical Region is reviewed. Two species are recorded for the first time from the Neotropics: Cercyon (Paracercyon) laminatus Sharp from Chile, and C. (s.str.) haemorrhoidalis Fabricius from Argentina. Cercyon panamensis Hansen is synonymized with C. (s.str.) nigriceps (Marsham); the latter species is recorded for the first time from Brazil, Costa Rica, Dominican Republic, Panama, Paraguay and Trinidad and Tobago, additional data are provided on its occurrence in Jamaica. Cercyon depressus subsp. uruguayanus Knisch is synonymized with C. (s.str.) depressus Stephens and its lectotype is designed; the latter species is recorded for the first time from Chile. Additional records of C. (s.str.) quisquilius (Linnaeus) from Mexico and Argentina are provided, and the species is recorded from Chile for the first time. Recent occurrence of C. praetextatus (Say) in Argentina is confirmed. A list of Cercyon species introduced to the Neotropical Region is provided, C. obsoletus (Gyllenhal) and C. limbatus Mannerheim are removed from the Neotropical fauna.
