    A distinctive new species of butterfly in the subtribe Euptychiina (Nymphalidae: Satyrinae), which is widespread throughout the upper Amazon in Colombia, Ecuador and Peru, is here described. The species is provisionally placed in the genus Magneuptychia Forster, 1964, although this is likely to change as the higher level taxonomy of Euptychiina is resolved and the genus is reviewed in detail.Authorisation has been given for this article to be loaded into the NHM repository (email A.

    Evaluation of Efficiency of Schoenly Trap for Collecting Adult Sarcosaprophagous Dipterans

    Communities of adult sarcosaprophagous dipterans were evaluated using both Schoenly traps (BST) baited with rabbit carcasses and the traditional forensic methodology (TradC) in the Sabana de Bogota, Colombia. During 42 sampling days, 2,726 adult dipterans were collected (2,291 by BST and 435 by TradC) belonging to 31 morphospecies (31 by BST and 23 by TradC) and 14 families (14 by BST and 10 by TradC). Significant differences in the species abundance, richness, diversity, and dominance were found between BTC and TradC. BST collected more individuals and species than TradC. Rank correlations and matched rank-abundance plots indicated a significant nesting of the dipteran community collected by TradC with respect to BST captures. By comparing the structure and composition of the collected communities, only those collected by BST showed repeatability of the results. The above-mentioned information allows us to consider BST as a superior methodology to perform inventories of Diptera imagoes associated with carcasses. In the community collected by BST, the most abundant and rich families were Calliphoridae, Muscidae, Phoridae, and Sarcophagidae, all of them necrophagous species associated with carcasses. Calliphoridae and Muscidae were dominant in the first stages of decomposition (fresh and active decomposition), and Phoridae was the principal family during decomposition, dry remains, and bones stages

    DIVERSIDAD DE ESCARABAJOS COPR脫FAGOS (Coleoptera: Scarabaeidae) EN UN BOSQUE DE GALER脥A CON TRES ESTADIOS DE ALTERACI脫N

    En un bosque de galer铆a, en los Llanos Orientales Meta-Colombia, se estudiaron los escarabajos copr贸fagos asociados a tres secciones dentro del bosque que presentaban diferentes tiempos de alteraci贸n: 50, 5 y 1 a帽o, provocados por procesos de entresacado de 谩rboles maderables. En cada secci贸n del bosque, por medio de trampas de ca铆da, se calcul贸 la riqueza, abundancia y diversidad durante el mes de julio (茅poca de lluvias). Se capturaron un total de 2358 individuos pertenecientes a 22 especies. La especie dominante durante el muestreo fue Canthidium cupreum, para las tres secciones. Del total de especies, el 27,3% son espec铆ficas para una secci贸n en particular, el 40,9% se encuentran en dos de las tres secciones y el 31,8% son generalistas. El 铆ndice de Brillouin, mostr贸 que la secci贸n del bosque con 5 a帽os de alteraci贸n, posee la mayor diversidad, con un total de 1233 individuos y 16 especies, seguido por la secci贸n del bosque con 1 a帽o, con 607 individuos y 14 especies y finalmente la secci贸n del bosque con 50 a帽os, con 518 individuos y 15 especies. Estos resultados indican que no existe una relaci贸n proporcional, entre la conservaci贸n de un bosque y la diversidad de copr贸fagos, y parece insinuar una correlaci贸n positiva entre 谩reas intervenidas y altos 铆ndices de diversidad. La actividad selectiva de entresacado de 谩rboles maderables est谩 contribuyendo en este ecosistema a la conservaci贸n de poblaciones de escarabajos, manteniendo procesos funcionales para este tipo de bosques
