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…

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.
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…
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;…
Orthetrum julia (Kirby 1900), subspecies falsum Longfield 1955, is reported for the first time from Yemen and the Arabian Peninsula (1 male, Wadi al-Ahjar, 15°27’53″N 43°52’32″E). The specimen is described and compared with specimens from Africa; taxonomically relevant structures are figured. The total number of species known from Yemen is raised to 37, from the…
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…
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…
New information shows that S. sinaiticum, is not divided into subspecies, as hitherto supposed. The subspecific name tarraconense, Jödicke, 1994 must be regarded as a junior synonym of sinaiticum., In contrast, the name arenicolor, Jödicke, 1994 denotes a taxon at full species rank, characterized by its larval and ligula morphology. This species is taxonomically identical…
