Two new ant species (Formicidae: Dorylinae, Ponerinae) from New Caledonia

Abstract

Two new species of ants (Hymenoptera: Formicidae) collected from New Caledonia are described and figured based on worker specimens: Leptogenys loarelae Ramage sp. nov. (Ponerinae, Ponerini) and Lioponera neocaledonica Jouault, Ramage & Perrichot sp. nov. (Dorylinae, Cerapachyini). All specimens were collected from the South Province of Grande Terre. These two new species are primarily distinguished from the other New Caledonian relatives by the size and shape of petiole for L. loarelae Ramage sp. nov. and by the presence of dorsolateral margins on the mesosoma for L. neocaledonica Jouault, Ramage & Perrichot sp. nov. Keys to New Caledonian Leptogenys and Lioponera are provided.

New species and records of Evanioidea and Stephanoidea from New Caledonia (Hymenoptera)

“…Since the publication of the checklist by Jennings et al (2013) of the species of Hymenoptera of New Caledonia, 66 species have been added to this fauna (Pauly et al 2013a(Pauly et al , 2013b(Pauly et al , 2015Kimsey 2014;Jennings et al 2015;Ramage et al 2015Ramage et al , 2019Breitkreuz et al 2016;Smith & Villemant 2017;Taylor 2018;Ortiz-Sepulveda et al 2019;Speranza et al 2019;Alencar & Azevedo 2020;Contarini et al 2020). Of these 66 species, 58 are endemic to New Caledonia.…”

Leptogenys pujoli, a new amazonian species, and the redescription of Leptogenys famelica Emery, 1896 (Formicidae: Ponerinae)

“…A key for the Colombian species (Fernández and Guerrero, 2019). However, in the same period, several papers have been published with new species descriptions and identification keys for the genus in other regions (Bakhtiar and Chiang, 2010;Zhou, 2012;Bharti and Wachkoo, 2013;Eguchi et al, 2014;Rakotonirina and Fisher, 2014;Xu and He, 2015;Arimoto, 2017;Sharaf et al, 2017;Arimoto and Yamane, 2018;Wachkoo et al, 2018;Ramage et al, 2019;Heterick, 2021;Subedi et al, 2022). The recent history indicates that, although several taxonomic works are being carried out for the genus, there is still a lack of broad revisions for Africa, Southeast Asia, and Americas.…”

Review of the Leptogenys unistimulosa species group (Hymenoptera: Formicidae) with the description of a new Amazonian species

“…Recent taxonomic treatments are improving our knowledge of the genus across the world, and just in the past decade fourteen new keys to identify Leptogenys species were provided: (1) Malaysia Sabah species (Bakhtiar and Chiang, 2011); (2) New World species revision and key (Lattke, 2011); (3) Fiji species key (Sarnat and Economo, 2012); (4) China species key (Zhou et al, 2012); (5) India species key (Bharti and Wachkoo, 2013); (6) Malagasy species revision and key (Rakotonirina and Fisher, 2014); (7) Oriental species key (Xu and He, 2015); (8) southeast Asia modiglianii species group revision and key (Arimoto, 2017); (9) Arabian Peninsula species key (Sharaf et al, 2017); (10) Oriental chinensis group species key (Wachkoo et al, 2018); (11) chalybaea species group key and Oriental species key (Arimoto and Yamane, 2018); (12) additions to the New World species (López-Muñoz et al, 2018); (13) New Caledonia species key (Ramage et al, 2019); and (14) Colombia species key (Fernández and Guerrero, 2019).…”
