We record the first occurrence of Mecistogaster amalia (Burmeister, 1839) for the state of Rio Grande do Norte, Brazil, which is the first record of this genus and family for the whole Northeast Region of Brazil. This record is based on four collected samples and extends by more than 1,500 km to the north, the area known of distribution of this species. © 2015 Check List and Authors.

Austrotepuibasis is described along with 3 new spp, viz.: A. alvarengai sp. n. (holotype S: Mato Grosso, SINOP, X-1970), A. demarmelsisp. n. (holotype ♂: Pará, Fordlândia, 11-1957), and A. manolisi sp. n. (holotype ♂: Mato Grosso, Alta Floreta, Cristalino Jungle Lodge, Rio Cristalino, 10-IX-2006). The new genus is close to Tepuibasis De Marmels, 2007 with which it shares the presence of an articulated ventrobasal lobe on cercus and differs mainly by the absence of the spiny auricle-like processes in penis, absence of dorsal cleft on ♀ tergum of S10 and other structural and colour characters. Whereas Tepuibasis is endemic to the high Pantepui region of Venezuela, Austrotepuibasis occurs in low altitude Amazon region of the Tapajós-Xingu prov. in Brazil.

Heteragrion is the most speciose and complex genus of neotropical Megapodagrionidae, with 47 species and one subspecies, and many of them are poorly defined. To improve the knowledge of the Brazilian species of the genus, 179 specimens of 13 of the 17 described species were examined. Four new species are described in tribute to the 40th anniversary of the rock band Queen: Heteragrion freddiemercuryi (Holotype: Peruíbe (24° 22' 48" S & 47° 04' 40" W-10 m), Sâo Paulo State-09-III-2000); H. brianmayi (Holotype and allotype: Parque Estadual da Serra do Mar-Núcleo Caraguatatuba, Caraguatatuba (23° 35' 36" S & 45° 25' 07" W-61 m), São Paulo State-05-II-2000 and 10-III-2002); H. rogertaylori (Holotype and allotype: Fazenda Trabiju, Pindamonhangaba (22° 50' 40" S & 45° 31' 01" W-651 m), São Paulo State-26-III-1999); and H. johndeaconi (Holotype and allotype: Alto Paraíso de Goiás (14° 10' 55" S & 47° 38' 36" W-1198 m), Goiás State-18-VI-2008 and 17-VI-2008), holotypes, allotypes and most paratypes deposited in FAAL. Diagnostic illustrations of all species studied are provided. Color photographs of live individuals of H. brianmayi, H. aurantiacum, H. consors, H. mantiqueirae, H. tiradentense and H. triangulare are also presented. Copyright © 2013 Magnolia Press.

The new sp. is described and illustrated based on a single specimen from the state of Bahia. Holotype ♂: Brazil, Bahia, Sao Desidério, 17-1-2004; deposited in author's collection. It can be separated from all other known congeners by the long and strongly sclerotized carina on the dorso-posterior margin of abdominal segment 10, which is much larger than the almost vestigial carina in T. dominicana, T. filiola and T. willinki.
