  Este artículo presenta resultados de un estudio de pequeños mamíferos no voladores en la Reserva Natural Ibanasca (Ibagué-Tolima), realizado con el fi n de aportar al conocimiento de las especies de mamíferos colombianos y del departamento del Tolima. Se muestrearon tres sitios: bosque de galería, bosque plantado y bosque altoandino, entre los 2.000 y 3.000 m.s.n.m., usando 20 trampas de caída/sitio. El muestreo se realizó entre los meses de abril y julio de 2005, a fi nales de la temporada de lluvias y comienzos de la temporada seca. Como cebo se emplearon atún y mantequilla de maní con hojuelas de avena. Se realizaron dos muestreos por zona, con un esfuerzo de captura de 432 horas/trampa. Se capturaron siete especies: Marmosops impavidus, Caenolestes fuliginosus, Cryptotis sp., Akodon affi nis, Microryzomys minutus, Mus musculus y Nephelomys albigularis.

  In this article, we present results from a study of small non-fl ying mammals in the Ibanesca Natural Reserve (Ibagué � Tolima), performed in order to contribute to the knowledge of mammals in Colombia and in the region of Tolima. Th ree places were sampled: riperian forest, planted forest and cloud forest, between 2000 and 3000 amsl, using twenty pitfall traps per site. Th e sampling was performed between April and July 2005, at the end of the rainy and the beginning of the dry season. Tuna and peanut butter with oat fl akes were used as baits. Two samples per zone were done with a capturing eff ort of 432 hours/trap. Seven species were captured: Marmosops impavidus, Caenolestes fuliginosus, Cryptotis sp, Akodon affi nis, Microryzomys minutus, Mus musculus and Nephelomys albigularis. M. minutus was the most abundant species, present in all sampling zones. Furthermore, Rodentia was the most abundant and diverse order. M. impavidus, C. fuliginosus y Cryptotis sp species have been reported for the first time in the region of Tolima.
