New species of Goja Navás (Psocodea: 'Psocoptera': Epipsocidae) from Colombia, Mexico and Peru.

Upon examination of epipsocid specimens recently collected in natural areas of Colombia, Mexico and Peru, 17 new species of Goja were found. These are here described and illustrated. An updated key for the identification of males of the described species of Goja is presented.

A new genus of Ptiloneuridae, its position within the family, and descriptions of five species (Psocodea, 'Psocoptera').

Upon examination of ptiloneurid specimens recently collected in forests of natural areas and Natural National Parks in Colombia, ten males and seven females were found that represent five species of an undescribed ptiloneurid genus. It differs from the other genera in the family by characters of the wings, hypandrium, phallosome, epiproct, female gonapophyses, and sternum IX. An identification key to the males of the genera of Ptiloneuridae, and a key to the species of the new genus are presented. A test on the validity and monophyly of the new genus, and its position within the family was also conducted.

Entomofauna acuática del Parque Nacional Natural Gorgona,Pacífico colombiano, con énfasis en Ephemeroptera y Plecoptera / Aquatic entomofauna from Gorgona National Natural Park, Colombian Pacific, with emphasis in Ephemeroptera and Plecoptera

Gorgona is a Colombian continental island that biogeographically belongs in the Choco region. This work constitutes a first approximation to the aquatic insects, with emphasis in Ephemeroptera and Plecoptera: distribution, ecology, and associations to the continental mainland. Between October 2010 and June 2011, immature and adult specimens were collected in five streams of the island´s Western sector using entomological nets, Malaise traps, and light traps. A total of nine orders, 28 families, 39 genera and 16 species of aquatic insects were found. New geographical records for Gorgona include: Dytiscidae (Coleoptera), Zelusia, Farrodes and Terpides (Ephemeroptera), Leucotrichia and Wormaldia (Trichoptera), Laccodytes, Neoelmis and Pheneps (Coleoptera), Maruina and Limonia (Diptera). As part of this study, four new species for each, Ephemeroptera and Plecoptera, were found. Leptohyphes jodiannae, L. maculatus and Hagenulopsis esmeralda are recorded for the first time for Colombia. Farrodes caribbianus, F. roundsi, Hagenulopsis zunigae, Zelusia principalis and Anacroneuria choco are reported for the first time for the National Park. The high abundance of families, genera, and species is similar to that of low order streams in the tropic mainland, particularly those associated to the Choco bio-geographical province. Rev. Biol.

Este trabajo constituye la primera aproximación al conocimiento de las especies que caracterizan la entomofauna acuática del PNN Gorgona, con énfasis en Ephemeroptera y Plecoptera, su distribución, ecología y relación con la parte continental. Entre Octubre de 2010 y Junio de 2011 se realizaron recolectas de estados inmaduros y adultos en cinco quebradas del sector oriental de la isla, con ayuda de redes entomológicas, trampas Malaise y de luz blanca y negra. Se registran nueve órdenes, 28 familias, 39 géneros y 16 especies. Por primera vez se reportan la familia Dytiscidae (Coleoptera) y los géneros: Zelusia, Farrodes y Terpides (Ephemeroptera), Leucotrichia y Wormaldia (Trichoptera), Laccodytes, Neoelmis y Pheneps (Coleoptera), Maruina y Limonia (Diptera). Se encontraron cuatro especies nuevas de Ephemeroptera y cuatro de Plecoptera, en proceso de descripción. Además, Leptohyphes jodiannae, L. maculatus y Hagenulopsis esmeralda son primeras citas para Colombia. Farrodes caribbianus, F. roundsi, Hagenulopsis zunigae, Zelusia principalis y Anacroneuria choco, reportadas para el país, amplían su rango de distribución para el PNN Gorgona. La riqueza de familias, géneros y especies es alta y se considera una extensión de la fauna de corrientes hídricas de bajo y mediano orden del trópico continental, particularmente en la provincia del Chocó biogeográfico.
