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…
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′ ′…
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.
Nososticta rufipes sp. nov. is described from Misool Island (Indonesia, Papua Barat, Kabupaten Raja Ampat). New records and notes on the species of the genus Nososticta on the Bird’s Head Peninsula and Raja Ampat Islands are presented. Nososticta lorentzi (Lieftinck, 1938) is placed in synonymy with N. nigripes (Ris, 1913).
To resolve a prevailing nomenclatorial confusion present in the genus Aciagrion, A. tillyardi Laidlaw, 1919 is placed in synonymy of A. approximans (Selys, 1876). The neotype of “Pseudagrion approximans”, a male specimen from Khasi Hills preserved in Coll. Selys Longchamps at RBINS, is designated to replace the lost holotype, which was an incomplete specimen of…
A synopsis is given of the knowledge of the genus Rhinagrion. The males of two new species are described from the Philippines: R. schneideri sp. nov. (holotype: Samar Island, Hinubangan, San Isidro, 31 March–5 April 1992) and R. reinhardi sp. nov. (holotype: Mindanao Island, Surigao del Sur, Carmen, 24 April 1995). Rhinagrion yokoii is synonymized…
In this synopsis all 50 species of the primarily neotropical genus Telebasis are keyed, diagnosed, and illustrated. Helveciagrion is considered a junior subjective synonym of Telebasis, T. coccinata a junior subjective synonym of T. coccinea, and T. limoncocha a junior subjective synonym of T. griffinii. Six new species from South America are described: T. carvalhoi…
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.
Orthographic details of 118 name-bearing types of Odonata and 11 ‘holotypes’ of forms, without nomenclatural status, are provided in two parts: the second and present paper deals with Zygoptera. The taxonomy of the gracilis-group of Chlorocypha and the Afrotropical members of Prodasineura and Aciagrion are discussed. Chlorocypha fabamacula is removed from synonymy with C. wittei;…
Orthographic details of 118 name-bearing types of Odonata are provided in two parts: the first and present paper deals with Anisoptera, the second with Zygoptera. 58 types pertain to good species, although the taxonomy of at least four is problematic. The details of 11 ‘holotypes’ of forms are also provided, although these and their names…
