Title: Igaponera curiosa, a new ponerine genus (Hymenoptera: Formicidae) from the Amazon
The monotypic ant genus Igaponera gen. nov. is proposed to include its type species I. curiosa (Mackay & Mackay, 2010). Igaponera gen. nov. is described and phylogenetically compared with other ponerine genera based on external morphology. The type species is known from a single gyne originally described in the genus Pachycondyla Smith, 1858. Igaponera curiosa is easily diagnosed by: costate sculpture on head, mesosoma, and petiole; short, robust, triangular mandibles with blunt apex; relatively large eyes set at mid-length on sides of head; lack of stridulitrum; and presence of distinct but relatively small arolia. Putative apomorphies of the new genus are: cuticular flange concealing metapleural gland opening; vertically standing hypostomal tooth with recessed base; stout mandibular shape with blunt apex; absence of stout spine-like setae on meso- and metatibial apices. Our phylogenetic results based on morphology suggest that Neoponera Emery, 1901 and Pachycondyla are the closest lineages to Igaponera, which shows intermediate characteristics as compared to those genera. The genus is apparently arboreal, known only from a seasonally flooded Igapó forest near Manaus, Brazil. Despite the collection site being frequented by researchers, no other specimens of this genus have been collected in over 40 years prior to this study.  more » « less

    The Peruvian genera of Edrotini (Pimeliinae) are revised. A new genus Pachacamacius Flores & Giraldo gen. nov. with two new species, Pachacamacius aguilari Giraldo & Flores sp. nov. (type species) and Pachacamacius koepckeae Flores & Giraldo sp. nov., is described. Two species originally described in the genus ProhylithusKaszab, 1964 are reassigned to two new monotypic genera: Sechuranus Flores and Giraldo gen. nov. (type species Prohylithus barbatusKaszab, 1964) and Koneus Giraldo and Flores, gen. nov. (type species Prohylithus peruanusKaszab, 1981). This article includes diagnoses for five genera and redescriptions or descriptions, distributional data, habitat records and habitus photographs for six species. A dichotomous key for all 11 Peruvian species of Edrotini, drawings of new species' male genitalic features, and distribution maps are also provided. A discussion of the external morphological characters and male genitalia of the new taxa compared to the genera and species previously described and on endemicity and zoogeography of Peruvian Edrotini is presented.

    For the first time in 21 years, a new genus of cardiochiline braconid wasp, Orientocardiochiles Kang & Long, gen. nov. (type species Orientocardiochiles joeburrowi Kang, sp. nov. ), is discovered and described. This genus represents the ninth genus in the Oriental region. Two new species ( O. joeburrowi Kang, sp. nov. and O. nigrofasciatus Long, sp. nov. ) are described and illustrated, and a key to species of the genus, with detailed images, is added. Diagnostic characters of the new genus are analyzed and compared with several other cardiochiline genera to allow the genus to key out properly using an existing generic treatment. The scientific names validated by this paper and morphological data obtained from this project will be utilized and tested in the upcoming genus-level revision of the subfamily based on combined morphological and molecular data.

    This study describes the worker and queen castes of the Neotropical ponerine Corrieopone nouragues gen. nov. , sp. nov. , an ant from the tropical rainforest in French Guiana. Worker morphology of the taxon is compared with those of other Ponerinae and the similarities between them are discussed, refining the definition of character states for some diagnostic characters at the generic level, providing an identification key to the Neotropical genera, and making some adjustments to the taxonomic framework within the subfamily. Descriptions, diagnosis, character discussion, identification key, and glossary are illustrated with more than 300 images and line drawings. Open science is supported by providing access to measurement data for specimens of the new genus, a matrix of character states for all ponerine taxa evaluated in this study, and specimen data for all examined material. The new or revived combinations presented here are Pachycondyla procidua Emery, comb. rev. , Neoponera curiosa (Mackay and Mackay), comb. nov. , Leptogenys butteli (Forel), comb. nov. , and Bothroponera escherichi (Forel), comb. nov. In addition, Leptogenys butteli is synonymized with Leptogenys myops (Emery), syn. nov.

    Five new species of the endemic Australian leafhopper genus Mayawa Fletcher, 2000 (M. affinifacialis sp. nov., M. bimaculata sp. nov., M. brevicephala sp. nov., M. kathyae sp. nov. and M. vestigia sp. nov.) are described and illustrated and a revised key to species is provided. One of the new species tested positive for a previously unknown strain of phytoplasma belonging to the 16SrV group. The related paralimnine genus Austroauridius gen. nov. based on A. iwaii sp. nov. from Queensland is also described and illustrated and a key to known genera of Australian Paralimnini is provided.

    The leafhopper tribe Platyjassini, endemic to Madagascar, is revised, largely based on specimens obtained in a recent bioinventory project led by the California Academy of Sciences. Platyjassini was previously known based on the type genus, Platyjassus Evans, 1953, and four described species. Betsileonas marmorata (Blanchard, 1840), the largest leafhopper recorded from Madagascar, presently known from a few specimens collected > 100 years ago and recently considered a genus and species incertae sedis within Cicadellidae, is newly placed in Platyjassini. Fourteen new genera and 54 new species are described and illustrated, and three new combinations are proposed. Pachyjassus gen. nov. includes three new species: Pachyjassus alatus sp. nov., Pachyjassus basifurcatus sp. nov. and Pachyjassus ranomafanensis sp. nov. Pallijassus gen. nov. is erected to include two species previously placed in Platyjassus, Pallijassus reticulatus (Evans, 1959) comb. nov. and Pallijassus stenospatulatus (Evans, 1959) comb. nov.
