Two new species of the genus Myrmarachne are described (M. acutidens sp. n., M. epigealis sp. n.), and M. macrognatha and M. melanocephala are redescribed from Flores specimens. The females of M. macrognatha are recorded for the first time. © T. Yamasaki, G. B. Edwards. Source

The final instar nymph of Anisagrion inornatum is described and illustrated based on five specimens (one reared) from southern Ecuador. It is the first to be discovered for the genus. The nymph of Anisagrion inornatum differs from its closest relative, Apanisagrion lais, by: (1) antenna shorter in relation to head length (ratio 1.35 in An. inornatum vs 1.55 in Ap. lais); (2) fewer palpal and premental setae (5 palpal and 4 or 5 premental setae in An. inornatum vs 6-8 palpal and 5-8 premental setae in Ap. lais); (3) venter of S3-S8 with medial dark stripe. The nymphs were found in a slow shallow seep overgrown with emergent wetland plants. © Gesellschaft für Biologische Systematik 2012. Source

I correct the publication dates for one genus and 14 species of Mecoptera (1 choristid, 4 bittacids, and 9 panorpids), and resurrect Panorpa confusa Westwood, 1841. Additionally, I provide a nomenclatural and taxonomic summary for these taxa, and a publication history for all of Westwood's related publications. Copyright © 2011 · Magnolia Press. Source

This treatise deals with the new genera Akonesis Opitz, new genus, Antennosus Opitz, new genus, Crusbatus Opitz, new genus, and Diutius Opitz, new genus. Two new species are described: Crusbatus spinosus Opitz, new species and Diutius pallidus Opitz, new species. A lectotype is designated for Akonesis pictipennis (Spinola). In addition to descriptions of taxa, a key to the genera and species and discussions of natural history and evolutionary relationships are provided. Eighteen characters were evaluated phylogenetically and analyzed with WINCLADA, in coordination with NONA, to generate two well-supported phylogenetic trees. It is postulated that the ancestor of the genera evolved in South America, with one species dispersal into the more eastern Panamanian terrain. The distribution of most species coincides with Quaternary forest refugia and South American clerofaunas. Source

The larvae of Cucujus c. clavipes Fabricius and C. c. puniceus Mannerheim are fully described and illustrated in detail for the first time. Based on larval and adult morphology the present recognition of two subspecies is maintained. Source
