Potamites ecpleopus (Cope, 1876)


Potamites ecpleopus (Cope, 1876) 

Type-locality. Middle and upper Amazon, in Brazil and Peru, restricted by Uzzell (1966) to Río Huallaga, somewhere between Rioja, Moyobamba and Balsaspuerto.  

Pertinent taxonomic references.

Distribution and habitat. Potamites ecpleopus  is endemic to Amazonia  , with an apparently disjunct distribution in western (delimited eastward by the Japurá, Purus, and Beni Rivers) and eastern Amazonia  (restricted to the Tocantins –Xingu and Xingu –Tapajós interfluviums, south of the Amazon) ( Fig. 15View FIGURE 15). MZUSP 64623, however, comes from the upper Comemoração River, a second order tributary of the Madeira River, an intermediary location between the western and eastern areas of occurrence. Potamites ecpleopus  occurs in Brazil, Colombia, Ecuador, Peru, and Bolivia ( Fig. 15View FIGURE 15). In Brazil, it is known from the states of Pará, Amazonas, Acre, Rondônia, and Mato Grosso. Potamites ecpleopus  is semiaquatic and diurnal, inhabits primary and disturbed terra firme forests, where it is found close to streams (with sandy, rocky or muddy bottoms), in swampy areas, on the leaf litter or directly on rocks or mud (occasionally on trunks, branches or limbs); active specimens are either at the margin of, or partially submerged in the water, and they may also be found under logs and in holes between rocks at the edge of water (Sherbrooke 1975; Duellman 1978; Cunha et al. 1985; Dixon & Soini 1986; Ávila-Pires 1995; Vitt & Zani 1996; Vitt & Ávila-Pires 1998; Vitt et al. 1998b; 1999; Schlüter et al. 2004; Whitworth & Beirne 2011).
