Gomphidae

Abstract: The new sp. is described and illustrated based on adult males obtained from mature larvae collected in Anchicaya zone, Valle del Cauca, Colombia, and reared in Universidad de Los Andes laboratory, Bogota, Colombia. The adult differs from the other described species of Perigomphus in the shape of the cerci and the size of the epiproct. Larvae are easy to collect in field but challenging to rear in the lab because of their habitat preferences. Adults are difficult to find in the field as they live high in the canopy. Holotype: reared male and exuviae, 22.xi.2016; deposited in Instituto de Ecologia, A.C., Xalapa, Mexico.

Abstract: Epigomphus pechumani Belle, 1970, was described based upon a single male specimen in poor condition, lacking specific locality in Colombia. Here the male is redescribed and the female is described and illustrated for the first time based on a total of 18 adults collected in Tatama National Park, Risaralda Department, and Farallones de Cali National Park, Valle del Cauca Department, Colombia. A diagnosis, notes on its biology and a distributional map are presented. All material is deposited in the Entomological collection of Universidad de Antioquia.

Abstract: A new gomphid species, named as Gomphidictinus tongi sp. nov. (Holotype male, Mt. Diaoluoshan, altitude 930m a.s.l., Lingshui County, Hainan Province, China) is described here. It is regarded as the third species of Gomphidictinus based on the presence of the basal spine on median segment of the penis organ. Gomphidia interruptistria Zha, Zhang & Zheng, 2005 is regarded as a junior synonym of Gomphidictinus perakensis (Laidlaw, 1902), which is recorded from Yunnan, China.

Abstract: Two new species of fossil dragonflies from the Middle Miocene fossil site Schasbach (Carinthia, Austria) are described. The presence of Gomphaeschna carinthiae sp. nov. and Ictinogomphus hassleri sp. nov. in the fossil record of Central Europe confirms the scenario of a more widespread distribution of the represented genera in the Miocene in contrast to their Recent distribution.
