The monotypic genus Mitragomphus Needham, 1944, is synonymized with the genus Gomphidia Selys, 1854.

NvE, RWG) is described, diagnosed and illustrated, and a key, diagnostic illustrations, and distribution maps are provided for the three species of the genus occurring in Argentina. The combination of well defined orange-red dorsal spots on S2-3 in mature specimens, well developed supplementary tooth in pretarsal claws, shape of occipital triangle of female, and of vesica spermalis, genital lobe, posterior hamule, and cercus of male diagnose the new species.

Diagnostic characters of the male holotype of 0. ambirufa are illustrated, and compared with those of 0. levis.

Geijskes in the RMNH. Illustrations of the variability for both taxa and illustrations, maps, and keys for all species are provided.

Research paper thumbnail of Generic diagnoses within a closely related group of genera: Brechmorhoga, Gynothemis, Macrothemis, and Scapanea (Odonata: Libellulidae)

The male of M. calliste is described and illustrated for the first time. Résumé-Après l'examen de la plupart des espèces de Brechmorhoga, Gynothemis, Macrothemis et Scapanea nous présentons ici des diagnoses révisées de ces quatre genres. Nous proposons les changements suivants à la taxonomie : Brechmorhoga archboldi (Donnelly, 1970) comb. nov., Gynothemis pumila (Karsch, 1890) comb. nov., Macrothemis heteronycha (Calvert, 1909) comb. nov. et Macrothemis calliste (Ris, 1913) comb. nov. Le mâle de M. calliste est décrit et illustré pour la première fois. Resumen-Se examinó la mayor parte de las especies de Brechmorhoga, Gynothemis, Macrothemis, y Scapanea. Estos cuatro géneros son re-diagnosticados y se proponen los siguientes cambios taxonómicos: Brechmorhoga archboldi (Donnelly, 1970) comb. nov., Gynothemis pumila (Karsch, 1890) comb. nov., Macrothemis heteronycha (Calvert, 1909) comb. nov. y Macrothemis calliste (Ris, 1913) comb. nov. El macho de M. calliste es descripto e ilustrado por primera vez. Perhaps no other group of libellulid dragonflies has suffered the vicissitudes of shifting species as much as the genera Brechmorhoga Kirby, 1894, Gynothemis Calvert in , Macrothemis Hagen, 1868, and Scapanea Kirby, 1889. These genera comprise an assemblage of over 60 small to moderately sized species with slender bodies, hyaline wings, and often long abdomens. Usually associated with lotic habitats, they are secretive in habits and can be mistaken for gomphids in the field. Species of these genera have been recognized as closely related and have been dealt with by numerous authors. Macrothemis was described by Hagen (1868), who included Libellula celeno Selys in Sagra, 1857, Libellula pleurosticta Burmeister, 1839, Macrothemis marmorata Hagen, 1868, and Macrothemis tenuis Hagen, 1868. He defined the genus by two characters exclusive to males: inferior tooth of the Can. Entomol. 138: 269-284 (2006)

This proposal seeks to achieve the least change in the nomenclature of the species currently placed in these two genera, in strict accordance with Principle 4 of the Code.
