After a decade, a new Venezuelan species of Latreille (Megaloptera, Corydalidae, Corydalinae) is discovered.

A new species of dobsonfly from Venezuela, Martins, Azevêdo, Hamada & Contreras, , was discovered a decade after the last description of a species of this genus in the country. The new species is morphologically similar to Contreras-Ramos & von der Dunk, sharing a uniform reddish coloration of body and wings and similar male genitalic structures. Likewise, it shares this particular coloration with Contreras-Ramos but the genitalic structure fits within the Contreras-Ramos species group.

Aquatic beetle diversity from Volcán Tacaná, Mexico: altitudinal distribution pattern and biogeographical affinity of the fauna.

Results of an aquatic beetle survey at Volcán Tacaná, Mexico, are presented with five altitudinal levels in a monthly sampling regime, aiming to estimate both diversity and altitudinal distribution patterns of the aquatic beetle fauna. The first list of aquatic beetle species from this mountain is presented, comprising 40 species in 32 genera and nine families, with four species recorded for the first time from Mexico and six recorded for the first time from Chiapas. The aquatic beetle fauna is characterized by Elmidae with 20 species, Dytiscidae with eleven species, Dryopidae with three, and Epimetopidae, Hydraenidae, Hydrophilidae, Gyrinidae, Lutrochidae, and Noteridae with one species each.

Comparative morphology of extant raptorial Mantispoidea (Neuroptera: Mantispidae, Rhachiberothidae) suggests a non-monophyletic Mantispidae and a single origin of the raptorial condition within the superfamily.

Adult external morphology of the extant raptorial Mantispoidea (Insecta: Neuroptera: Mantispidae and Rhachiberothidae) is compared emphasizing the morphology of the subfamily Symphrasinae as a key group to understand the phylogenetic relationships among the members of the superfamily. Plega dactylota Rehn, 1939 is thoroughly characterized in order to exemplify the morphology of the Symphrasinae. Additionally, following a review of the literature and examination of comparative material of Dilaridae, Berothidae, Rhachiberothidae and all Mantispidae subfamilies, a new interpretation of the components of the raptorial apparatus (i.

Herein we provide the complete label information, specimen condition, locality and habitus pictures of the Osmylidae primary types of the Natural History Museum, with some historical information about the specimens.

Redescription of larva of the South African endemic dobsonfly genus Chloroniella Esben-Petersen, 1924 (Megaloptera, Corydalidae), with a proposed terminology for Corydalidae larval sclerites.

Chloroniella Esben-Petersen is a relict, monotypic genus of Corydalidae (Megaloptera), considered sister to the remaining dobsonfly genera (Corydalinae); it is the only genus of Corydalinae known from the Afrotropical region. The larva of its only species, C. peryngueyi Esben-Petersen, 1924, was originally described by Barnard in 1931.

Isostenosmylus ammirabilis sp. nov., a remarkable new species of lance lacewing (Neuroptera: Osmylidae) from the Colombian Andes.

Isostenosmylus Krüger, 1913 is the richest genus of Osmylidae of the Neotropical region, with 17 described species so far, which are distributed mainly in the Andean region and in the South of Brazil and Paraguay. A new remarkable Colombian species of Isostenosmylus-I. ammirabilis sp.

The genera of the lance lacewing family Osmylidae (Neuroptera) and extinct allied families (Archeosmylidae, Saucrosmylidae) are reviewed. A key to living Osmylidae genera of the world is presented. Each genus is diagnosed and figured with a checklist of species included for each.

Notes on the pleasing lacewing genus Dilar Rambur, 1838 (Neuroptera, Dilaridae), with description of a new species from Vietnam.

In recent years many studies have been undertaken on the species of the genus Dilar Rambur, 1838 that occur in Asia, these have greatly increased the knowledge of Dilaridae in that region. Dilar has 69 valid species distributed in the Palaearctic and Oriental regions. In this paper we describe a new species Dilar aspoeckorum sp.

First record of spongillaflies (Neuroptera: Sisyridae) from Colombia.

The family Sisyridae (spongillaflies) is a small group of neuropterans distributed in all Biogeographic realms (Cover & Resh 2008). As in Nevrorthidae, Sisyridae is distinguished among other Neuroptera families by their strictly aquatic larvae (Wichard et al. 2002).

Neotropical osmylids (Neuroptera, Osmylidae): Three new species of Isostenosmylus Krüger, 1913, new distributional records, redescriptions, checklist and key for the Neotropical species.

Osmylidae is a small family of Neuroptera with a worldwide distribution. Only four subfamilies and five genera of Osmylidae have been reported to date for the Neotropical region, with a total of 16 species, whilst 200 species are known in the world. In this study three new species are described-Isostenosmylus bifurcatus n.

Brazilian dustywings (Neuroptera: Coniopterygidae): new species of Incasemidalis Meinander, 1972 and Coniopteryx Curtis, 1834, checklist and key for the Brazilian species.

Two subfamilies and three genera of Coniopterygidae have been reported to date for Brazil, with a total of 44 of species. In this paper two new Brazilian species are described from the genera Coniopteryx Curtis, 1834 and Incasemidalis Meinander, 1972-C. (Scotoconiopteryx) letardii sp.
