Microneura is a junior synonym of Protoneura (Zygoptera, Coenagrionidae)

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 group of Orthemis revisited: a synopsis including a synonymy and description of six new species of Orthemis from South America (Odonata: Libellulidae)

The levis and ferruginea groups of Orthemis are redefined. Six new species of Orthemis are described: O. aciculata sp. nov.

Kalocora, a junior synonym of Cora (Odonata: Polythoridae)

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, a junior synonym of O. ambirufa (Odonata: Libellulidae)

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…

A study of Coeliccia cyanomelas Ris, 1912 (Odonata: Platycnemididiae)

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…
