Aciagrion Selys, 1891 is one of the taxonomically difficult and poorly known genera of Oriental damselflies. Aciargion hisopa race krishna Fraser, 1921 was described from Mahabaleshwar, Maharashtra, India. However, later Fraser (1933) doubted the taxonomic necessity of this taxon. His notion of Aciagrion hisopa (Selys, 1876) was erroneous, as evidenced by syntypes of this species…
Macromidia donaldi pethiyagodai subsp. nov. (holotype ♂: Sri Lanka, Ratnapura District, near Kudawe, 6.26°N, 80.25°E, 03 July 2007; paratype ♀, same location, 17 April 2008, to be deposited in the Sri Lanka National Museum, Colombo) is described and figured. Its phenotype differs from that of M. d. donaldi from India. This is the first record…

Gomphus (Gomphurus) septima delawarensis is described from the Delaware River, NJ, PA, and NY (Type locality: Flatbrookville, NJ). The new subpecies differs from nominate G septima septima Westfall (new status) mainly by differences in the male cerci and eplproct, and in the female vulvar lamina and lateral occipltal horns. The larvae of the two subspecies…
The taxonomic status of the Central Asian damselfly Calopteryx samarcandica was determined on the basis of molecular and phenotypic data from the Kugitang Mountains, SE Uzbekistan.
We explore the genetic diversity and phylogeography of the dragonflies Orthetrum cancellatum and O. coerulescens in Europe based on mitochondrial and nuclear DNA. Orthetrum cancellatum has a clear division between a group comprising Maltese, Italian, and central and northern European populations…
The Sulawesi species of the genera Libellago and Sclerocypha are revised. L. asclepiades, L. rufescens, L. xanthocyana and S. bisignata are redescribed, and three species of Libellago- one with four subspecies – are described as new to science, viz. the closely allied L. daviesi sp. nov. from the northern arm of Sulawesi and L. man-ganitu…
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;…
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…
Although there are many records of Orthetrum coerulescens in Bulgaria, the presence of the nominotypical subspecies is doubtful. A critical analysis of all specimens available revealed that they belong either to O. c. anceps or to intermediate forms, but not to O. c. coerulescens. The latter taxon is therefore omitted from the Bulgarian species list,…
