Diaphlebia richteri is shown to be a junior synonym of Zonophora nobilis. The confusion started by a generic misplacement due to the failure to observe the subalar carina spine which is present in Zonophora but not in Diaphlebia.
During 2.5 months of intensive fieldwork in Colombia (departments of Cauca, Nariño, and Putumayo, South America) from January to March 2017, we visited 13 localities and collected 291 specimens of 68 species of Odonata, including 17 new records for the country. We report range expansions for several species assessed as data deficient or under some…
Microneura caligata (Hagen in Selys, 1886) is an endangered damselfly presently known from five localities in the central mountains of Cuba. The precise systematic position of this species within the former Neotropical Protoneuridae has been the subject of debate, with previous results from a phylogenetic analysis based on morphology suggesting that the genus Microneura should…
The levis and ferruginea groups of Orthemis are redefined. Six new species of Orthemis are described: O. aciculata sp. nov. (♂ holotype: Surinam, Para Dist., road near forest, Zanderij I (5°32′ N, 55°10′ W), 17 January 1957, leg. J. Belle [RMNH]), O. celata sp. nov. (♂ holotype: Brazil, Pará State, Rio Gurupí, Canindé (0°30′57′ ′…
Calilestes pallidistigma and Lestomima flavostigma, both sole representatives of their respective genera, are shown to belong to the genus Rhipidolestes. Rhipidolestes flavostigma comb. nov. is determined to be a junior synonym of R. truncatidens. R. pallidistigma comb. nov. is deemed to be a valid species.
Supplementary specimens of the monotypic genus Kalocora show that diagnostic characters employed by Kennedy, based on the original description of Cora aurea are too variable, and therefore Kalocora is here relegated to synonymy under Cora.
Orthemis sibylla is shown to be a junior synonym of O. ambirufa, based on a comparison of the holotype male of O. ambirufa with voucher specimens in the UMMZ identified as O. sibylla by Ris and specimens of this species from French Guiana and Venezuela in the RWG collection. Diagnostic characters of the male holotype…
Damselflies of the genus Lestes Leach, 1815 are represented in India by 11 species. Using specimens collected over the last five years, we report on the rediscovery of Lestes nigriceps in India after 98 years, at two new localities in the Western Ghats.
The taxonomy and distribution of dragonflies of the genus Heliogomphus from the Western Ghats of southern India are discussed. A morphological study of fresh male specimens from the field, as well as holotypes and lectotypes from repositories was undertaken.
Coeliccia cyanomelas is studied based on a large series of specimens from its whole distribution range. Intraspecies variations of color patterns on the thorax are discussed. Coeliccia sexmaculata Wang, 1994, Coeliccia mingxiensis Xu, 2006, and Coeliccia wilsoni Zhang & Huo, 2011 are all assigned as junior synonyms of Coeliccia cyanomelas. One ‘variety’ from Guizhou is…
