We described the body and cranial characteristics, which are within the range known for the species, except that the tail is bicolored to the medial portion and the rear half is uniformly dark.
The digestive tract contained traces of insects Corydalus sp. Our record in the Jurumbuno River is the third locality in Ecuador for the species studied, 40 years after its previous capture.
Introduction The genus Ichthyomys encompasses four species of cricetid rodents adapted to the semi-aquatic life, which occur only in the Neotropics, from Panama to southern Peru, including northeastern Venezuela.
The species of the genus Ichthyomys inhabit lowland and montane forests, and moors, in an altitudinal range of to 3, m a. The genus feeds preferentially on shrimp, crabs, insect larvae, semi-aquatic cockroaches and fish Thomas ; Voss et al. Similarly, this rodent may be preyed upon by nocturnal birds of prey Brito et al.
The latest collection for Ecuador was carried out by A.
This specimen was determined Pacheco as Ichthyomys hydrobates. In the present work we report a new locality for I. The morphological and cranial measures of the specimen collected are reported, and the palmar and plantar structures are described; additionally, the stomach contents of this specimen are mentioned. The information about the characters described may be useful for future taxonomic, phylogenetic and ecological studies, while contributing relevant data to the protection of this poorly known species.

Materials and Methods One specimen of I. The collection area belongs to the Eastern Subtropical plains Albuja et al. In the collection site, the Jurumbuno river measures approximately 12 m wide by 1 m deep Figure 2. The specimen was caught with a pound net with mm mesh-size. Several fish species have been captured in the same site, including sardines Astyanax spp. Cranial measures were taken with a digital gauge to the nearest 0.

The measures, body and cranial features were recorded following Voss Results The main body and cranial measures of the I. The specimen DMMECN 4, shows a narrow skull and interorbital region, with obvious supraorbital foramen, carotid circulation pattern 3 sensu Vosspresence of the orbicular apophysis of the malleus Figure 3 and leg longer than Externally, the specimen shows the following features: The tail, longer than the head-body length, is thick, robust and densely covered with hairs, dark brown dorsally, while ventrally it is whitish to the medial region and dark brown distally Figure 4.
The hairs at the tip of the tail protrude 7.
The front leg is medium-sized and thin; it has five fingers with claws, with the thumb being shortened with a short and rounded claw. The remaining fingers are relatively short, with enlarged and curved claws.Las Leyes de la Termodinámica en 5 Minutos
The metacarpal region is whitish with long dark brown hairs. The palmar surface shows five pads: The dorsal region of the foot is white, with short and medium black hairs, most noticeable at the outer edge.
The dorsal surface of the phalanges is white with black hairs. Five plantar pads are present; the thenar tubercle is well developed and the hypothenar is absent. There is a wide space between the thenar pad and the first interdigital pad. Plantar surfaces are tuberculate. Digits are relatively short and wide. The outer edges of the foot and digits are bordered by fringes of hairs that measure 2.
The stomach and digestive tract contained remains of an arthropod Corydalus sp. Discussion Traditionally, the population of I.

The specimen examined DMMECN 4, has a bicolored tail to the medial part, while the posterior half is uniformly dark a character not previously recorded in Ichthyomys. Other species of Ichthyomys I. Additional specimens should be collected from localities to fill the gap of nearly 1, kilometers between the Ecuadorian and Peruvian localities, in order to assess within- and between-population variation patterns in tail coloration.
The stomach contents of I.
Tewes and Schmidly indicated the Ocelot is able to occupy different sort of habitats such as humid tropical, subtropical forests, swampy savannas, estuarine mangroves and thorny bushes, but it is most common at elevations lower than m Eisenberg We recorded it in both season for which we think that felid is a permanent resident in the area. Lizcano and Sissa recorded it in the Tabaconas-Namballe National Sanctuary and mentioned that the mountain tapir is absent south of Huancabamba valley.
Our record south of the Huancabamba depression by an unequivocal track extends significantly its range and challenge the role of the Huancabamba Depression as a potential barrier for large mammals. Noteworthy records of mammals found in the study site demonstrates its importance and the need for a better protection status of the Pagaibamba Forest.
In spite of the advance in knowledge, more species are expected to be known in the region. A for allowing us to use and publish this data, and for the logistic support to accomplish this work.
