Pseudagrion emarginatum is removed from the synonymy of P. melanicterum. The following synonymies are established: P. coeruleiceps of P. emarginatum and P. angelicum of P. camerunense. The latter, formerly known as Enallagma camerunense, should be removed from the list of threatened African Odonata.
Aeshna (Hesperaeschna) condor sp. nov. is described and illustrated from four males and six exuviae. The adult color pattern does not resemble that of any other Venezuelan species, but structurally the new species comes closest to A. (H.) punctata and A. (H.) joannisi. This latter is here recorded for the first time from Venezuela, and…
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,…

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…
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 final-stadium larva of Leucorrhinia patricia Walker is described from six exuviae with associated teneral adults collected in northern British Columbia. L. patricia belongs to the group of nearctic Leucorrhinia that has larvae with three ventral stripes. The larvae are very similar to those L. hudsonica (Sélys) larvae that are small and lack dorsal spines….
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.).
This paper is dedicated to Philip S. Corbet on the occasion of his 70th birthday.
