Two Cordulia species have been described so far, the Eurasian C. aenea and the North American vicariant C. shurtleffii. The names amurensis, tatrica, turfosa, laubmanni, linaenea and aeneaturfosa are available in the synonymy of C. aenea. Out of these, only the name amurensis is deemed to denote a separate taxon, which is currently regarded as…
We address six issues raised by Nel, Garrouste and Schubnel (2019) concerning the scheme of wing vein homology and nomenclature proposed by Trueman and Rowe (2019); showing in particular how evidence presented in a tomographical study of a dragonfly wing by Jacquelin et al. (2018) fits into this scheme.
Existing nomenclatures for the venation of the odonate wing are inconsistent and inaccurate. We offer a new scheme, based on the evolution and ontogeny of the insect wing and on the physical structure of wing veins, in which the veins of dragonflies and damselflies are fully reconciled with those of the other winged orders. Our
The Odonata from the Refúgio Estadual da Vida Silvestre do Rio Pandeiros (RVSP), located in the Cerrado domain, Minas Gerais State, Brazil, were rapidly surveyed. Sampling efforts were undertaken along the Rio Pandeiros margins during four sampling periods between the rainy (spring–summer) and dry seasons (autumn–winter) from July 2014 to April 2015. We sampled 97…
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…
The author’s previous rejection of Selys’ legions as available family-group taxa is restated and elaborated, strictly based on the provisions of the International Rules of Zoological Nomenclature (4th ed.).
