Two new species of Brasineura are described from Brazil based on male specimens: Brasineura calori sp. n. (Bahia: Brazil) and Brasineura morrense sp. n. (Bahia: Brazil). They differ from the other species in the genus, in which the males are known, by hypandrium and phallosome structures. New records and comments on variation in the fore- and hind- wing venation of B. troglophilica Silva-Neto García Aldrete and B. diamantina Silva-Neto García Aldrete are presented. The identification key to male Brasineura species is updated.

Ophiocordyceps dominicanus Poinar & Vega sp. nov. in Dominican amber and Polycephalomyces baltica Poinar & Vega sp. nov. (Hypocreales: Ophiocordycipitaceae) in Baltic amber are described as entomopathogenic fungi of bark lice (Psocoptera). The specimens possess several features unknown in extant synnematous entomopathogenic fungi such as a tubular dark synnema with a straight, pointed tip bearing spores over the entire surface in O. dominicanus, and a globular yellowish synnema developing on the tip of the host's antenna in P. baltica. These are the only known fossil entomopathogenic fungi of bark lice, making them unique not only for their characters but also in respect to their selection of developmental sites on their bark lice hosts.
RESUMO
Seven new species of Brazilian Euplocania are described and illustrated, five species belong in the amabilis species group (Euplocania bujariensis n. sp., Euplocania cearaensis n. sp., Euplocania hutchingsi n. sp., Euplocania pseudopictaoides n. sp. and Euplocania xavieri n. sp.) one species belong in the marginata species group (Euplocania uariniensis n. sp.) and one species is not assignable to any of the known species groups of the genus. For this species, E. quinquedivisa n. sp., a new species group is here diagnosed, the quinquedivisa group. Information on sexes known and distribution is included for all known species of Euplocania. The first identification key to males of Euplocania species from Brazil is presented.

A species of Lithoseopsis Mockford, from the Brazilian state of Pará, is described and illustrated. It is the first species of Lithoseopsis recorded in Brazil, and the first of that genus known in South America. It differs from all the other species in the genus in details of the forewing pigmentation and spermapore sclerite. A map with the distribution of the Lithoseopsis species is included and two species groups of Lithoseopsis are diagnosed.

Two species of Waoraniella from Valle del Cauca, represented by both sexes, are here described and illustrated. The new species were found in the Andean region, between 1000-2000 m above sea level, constituting the first record of the genus outside the Amazon Basin. An identification key and a distribution map of the known Waoraniella species is included.

Based on a survey of the genus Triplocania (Psocodea: 'Psocoptera') in forests of natural areas and Natural Parks in Colombia, 46 species were found, 42 of which are new to science and are here described and illustrated. Added to T. colombiana García Aldrete, the number of species of Triplocania now known in Colombia is raised to 47. To date, 40 species described in this paper are recorded only in Colombia, and seven species are shared with neighboring countries, three with Brazil, one with Venezuela, two with Ecuador, and one with Ecuador and Brazil. Females of three previously known species are also described. An identification key to the species of Triplocania present in Colombia is included.

Seven species of Loneura from natural areas of Valle del Cauca, Colombia, are described and illustrated. The female of L. andina is described for the first time. Two additional species, known only from the National Natural Park Gorgona (Cauca), are also recorded in Valle del Cauca. The new species are assigned to the infrageneric groups known in the genus. An identification key to males of Loneura is included.

Diversity of Psocoptera (Insecta: Psocodea) at the National Natural Park Gorgona (Pacific Ocean, Colombia). Psocopterans are insects that have been recorded from all zoogeographic regions but have more species in the tropics. We studied their diversity of in four habitats (Beaches, Village, Trails and Arboreal strata) at the Gorgona National Natural Park, Colombia, from samples collected during November 2009 and October 2010. We added the arboreal Psocoptera collected by canopy fogging in November 2007. The specimens collected were identified to genus and/or to species or morphospecies level. Comparisons were made of the richness and diversity among sites. Although there was no significant difference in the diversity estimated by the Shannon-Wiener index, high species richness and abundance were recorded for the Beaches and Village habitats. The psocid community of Gorgona occurs mainly where vegetation cover is low. Rev. Biol. Trop. 62 (Suppl. 1): 257-264. Epub 2014 February 01.
El presente trabajo tuvo como objetivo establecer la diversidad de Psocoptera en cuatro hábitats (Playas, Poblado, Senderos y Estratos arbóreos) del Parque Nacional Natural Gorgona, Colombia. Se realizaron dos campañas de recolecta durante los meses de noviembre de 2009 y octubre de 2010, con un total de 30 horas/hombre. Se revisó además el material de artrópodos arbóreos del muestreo realizado en el parque en noviembre de 2007, depositado en el Museo de Entomología de la Universidad del Valle (MUSENUV). Los especímenes recolectados en los cuatro sitios, se identificaron como mínimo a nivel de género, y posteriormente se cuantificaron para comparar la riqueza específica y diversidad entre los sitios. Aunque no hubo diferencia significativa en la diversidad estimada por el índice de Shannon-Wiener, se registró una alta riqueza de especies y abundancia para los hábitats Playas y Poblado. Se observó una tendencia de los Psocoptera del PNN Gorgona a ocupar espacios donde la cubierta vegetal es baja.
