A distinctive new species of sturnirine bat, Sturnira (Sturnira) koopmanhilli, new species (Chiroptera: Phyllostomidae: Stenodermatinae), is described from 49 specimens collected in the Pacific drainage of the western Andes, at 300-2000 m in western Ecuador and Colombia. This yellow-shouldered bat is endemic to this Chocoan region where it is known from nine localities in Ecuador (Esmeraldas and Chimborazo) and Colombia (Chocó, Valle del Cauca, and Nariño). This moderately large Sturnira species (forearm length, 48.1-52.4 mm) is compared with Sturnira mordax (Goodwin, 1938) (forearm length, 43.0-49.2) and Sturnira ludovici Anthony, 1924 (forearm length, 43.9-49.5). Salient characters that distinguish the new species from these two cogeners include a bicolored appearance of dorsal fur, recessed hypoglossal foramina, presence of a sulcus on posterior faces of upper canines, and teeth P2 > M2. Teeth I1 and i1 are protrudent and robust, which set the new species apart from other Sturnira species. Spacing between teeth P1-M3 and p1-m3 is present in the new bat and with the subgenus Corvira. The new species is placed in the subgenus Sturnira.
Las técnicas de exclusión de murciélagos de las viviendas humanas como metodología de manejo son efectivas para la solución del conflicto entre murciélagos caseros y el hombre. Sin embargo, el desalojo de los murciélagos del antiguo albergue limita el restablecimiento de estos animales en refugios alternos. Por ello, se optó por brindar refugios artificiales como complemento a las actividades de exclusión de los murciélagos. Las experiencias se efectuaron en la Universidad del Valle donde se construyeron dos tipos de casas para murciélagos (CPM). En dos de las cinco CPM instaladas, comenzó a haber ocupación por el murciélago mastín casero o casero común (Molossus molossus). En este documento se describen los criterios que fueron tenidos en cuenta para el diseño, construcción, instalación y postura de las CPM.
