GONZALEZ SORIANO, E.  and  NOVELO GUTIERREZ, R.. Oplonaeschna magna sp. nov. (Odonata: Aeshnidae), from Mexico with a description of its larva. Rev. biol. trop [online]. 1998, vol.46, n.3, pp.705-715. ISSN 0034-7744.

Oplonaeschna magna sp. nov. (Odonata:Aeshnidae) (holotype x and allotype Ç deposited at CNIN UNAM-MEX., México, D. F.) is described and illustrated from specimens collected in the states of Estado de México, Guerrero, Hidalgo, and Morelos, México. This is the second species of the genus Oplonaeschna. Adults of O. magna can be separated from those of O. armata (Hagen, 1861) by their larger size and broader thoracic stripes. The larva of the new species is also easily distinguished from that of O. armata by its larger size and longer prementum, and by structural differences of palpal lobes and epiproct. The larva of O. armata is briefly redescribed, illustrated and compared to that of O. magna. Notes on the biology of the new species are provided.
