Resumen Se realizó un inventario de las mariposas de Isla Grande, la isla más extensa del Archipiélago Islas del Rosario (Cartagena de Indias) en el mar Caribe colombiano, a partir de muestreos realizados entre agosto y noviembre de 2017, empleando redes entomológicas y trampas Van Someren-Rydon en fragmentos de bosque seco tropical, donde se ubicaron 13 transectos de 100 m x 10 m. Se registró un total de 129 individuos distribuidos en seis familias, 14 subfamilias y 25 especies. La presencia de Polygonus savigny (Hesperiidae) se confirma para el Caribe colombiano. La familia Nymphalidae fue la más representativa, por el contrario, las familias Lycaenidae, Riodinidae y Papilionidae presentaron la menor representatividad. Las especies se clasificaron a partir del número de individuos capturados, registrándose cinco especies abundantes, cuatro comunes, tres escasas y 13 raras. Se considera que la realización de muestreos en época seca y de transición permitirá ampliar el número de especies registradas para la isla. Estos resultados constituyen el primer listado de las mariposas de Isla Grande, información que constituye una línea de referencia para posteriores estudios.

Abstract An inventory of the butterflies of Isla Grande, the largest island in the Islas del Rosario Archipelago (Cartagena de Indias) in the Colombian Caribbean Sea, was developed based on samplings carried out between August and November 2017 using entomological nets and Van Someren-Rydon traps in fragments of tropical dry forest, where 13 transects of 100 m x 10 m were located. A total of 129 individuals distributed in six families, 14 subfamilies and 25 species were recorded. The presence of Polygonus savigny (Hesperiidae) is confirmed for the Colombian Caribbean. The Nymphalidae family was the most representative. On the contrary, the Lycaenidae, Riodinidae and Papilionidae families presented the least representativeness. The species were classified based on the number of individuals captured, registering five abundant species, four common species, three scarce and 13 rare. It is considered that carrying out samplings in the dry and transitional season will allow expanding the number of species recorded for the island. These results constitute the first list of the butterflies of Isla Grande, information that constitutes a reference line for further studies.

Abstract A new species of Pulmoniscus Leistikow, 2001 from Department of Bolívar, Colombia, is described. It constitutes the first record of the genus for the country and for the continental portion of the Neotropics. Pulmoniscus turbanaensis n. sp. is distinguished by the male pereopod 7 ischium with concave sternal margin and the shape of the male pleopod 1. In addition, ecological remarks and a distribution map are provided.
