TRETANORHINUS MOCQUARDI (Swamp Snake). ECUADOR: PROVINCE OF ESMERALDAS: Atacames (00º52’12”N, 79º50’32”W, 8 m elev), 13 and 25 February 1990, V. Cevallos and E. Kramer. Universidad San Francisco de Quito & Fundación Herpetológica G. Orcés, Quito, Ecuador (FHGO-USFQ 121–5, 187; collected at night in water, at a shrimp pond near coastline). Verified by J.-M. Touzet. The species was known from Panama, with no records from Colombia (Dunn 1939. Copeia [4]: 212–217; Peters and Orejas-Miranda 1970. USNM Bull. 297). Uetz (1995–2005. The EMBL Reptile Database. Online. EMBL Heidelberg. <http://www.reptile-database.org>) mentioned the species from Ecuador, citing Almendáriz (1992 [1991]) In Barriga et al. [eds.], Lista de Vertebrados de Ecuador. Revista Politécnica, Quito XVI [3]: 89–162); however, the author does not mention the species in that paper, nor subsequent lists (Coloma et al. 2000–2004. Reptiles de Ecuador. Online. Museo de Zoología, PUCE Quito, Ecuador. <http://www.puce.edu.ec/zoologia/>). First vouchered country record. Extends known distribution ca. 900 km S from nearest localities in Panama (Dunn op. cit.).

Biology of snakes of the genus Tretanorhinus: an integrative review

Many aspects of the biology of various snake species remain unknown, and the extent of this lack of information is not always clear. As new research usually depends upon previous findings, the gaps in our knowledge and the accuracy of published information are of major importance. Therefore, an analysis of all available information on snakes of the genus Tretanorhinus, from both the literature and museum specimens, is presented here to illuminate existing knowledge gaps. The database compiled from 87 documents referring to snakes of this genus and 755 specimens held in scientific collections revealed major gaps and contradictory information for all four species of this genus. Data on morphology, ecology, and natural history are completely absent for T. mocquardi and T. taeniatus, whereas confusing distribution reports exist for T. nigroluteus. The potential consequences of these problems were determined, and some suggestions for correcting them are addressed. Specifically, we consider that focused efforts on the validation of current species and subspecies, field and lab studies of ecology and behavior, and estimations of population dynamics, are necessary.
