The final stadium larva of Anisagrion allopterum is described for the first time for Middle America, based upon specimens reared and emerging in the field, from Cartago, Province, Costa Rica. Detailed illustrations are also provided. The larva of this species is characterized by a slender yellow body, premental setae 4+1, five palpal setae, male cerci…
The final instar of Remartinia luteipennis luteipennis (Burmeister, 1839) is described and illustrated based on reared specimens from Salta Province, Argentina. It is compared with R. secreta and R. l. florida, and with Calvert’s original description of R. l. luteipennis. Remartinia l. luteipennis can be differentiated by the length of the lateral valvae of the…
Coeliccia schorri sp. n. is described based on both sexes (holotype male from Dak Roong Commune, K’bang district, Gia Lai province, central highlands of Vietnam). The combination of the characters of a large pruinose spot on the synthorax, blue abdominal tip, and white appendages in the male and a long spine on the posterior pronotal…
The poorly known Ceriagrion mourae is redescribed based on the first material from Zambia and compared with the similar C. banditum, C. junceum and C. suave. Molecular data place C. mourae as a sister taxon to the clade (C. bakeri (C. banditum, C. junceum)). Genetic distances between the above-mentioned species are similar at c.7–9% (K2P)….
The larva of Erythrodiplax media is described and illustrated based on two exuviae of reared larvae and one final stadium larva collected in Xangri-lá, State of Rio Grande do Sul, Brazil. The larva of E. media can be distinguished from other species of Erythrodiplax by the presence of lateral spines on S8 and S9, the…
Coeliccia phamiha sp. n. (holotype male and paratype female from Dak Et bridge, Deo Lo Xo, Phuoc Son district, Quang Nam Province, Central Vietnam, deposited in zoological collection of Duy Tan University) is described based on both sexes. Judging by the structure of genital ligula and appendages of the male and prothorax of the female…
Gomphurus gonzalezi (Dunkle) is a locally distributed dragonfly ranging from the Lower Rio Grande in south Texas southward to San Luis Potosi state in northeastern Mexico. We describe and illustrate the nymph based on specimens from Hidalgo County, Texas. The palpal lobe of G. gonzalezi has 7–8 small teeth in a straight line with the…
The Odonata from the Refúgio Estadual da Vida Silvestre do Rio Pandeiros (RVSP), located in the Cerrado domain, Minas Gerais State, Brazil, were rapidly surveyed. Sampling efforts were undertaken along the Rio Pandeiros margins during four sampling periods between the rainy (spring–summer) and dry seasons (autumn–winter) from July 2014 to April 2015. We sampled 97…
The larva of the genus Mesopodagrion was identified with the help of DNA barcoding and described for the first time. The larvae have flat horizontal gills resembling those of Argiolestidae but the adults lack setae on the shaft of the genital ligula. Molecular data are shown to be useful and necessary in larval identification and…
