TL;DR: A new gomphids species, named as Gomphidictinus tongi sp.
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.
TL;DR: A new species of Gomphidia Selys, 1854 is described from southern Western Ghats, India based on a male specimen that is very distinct from all the known species from Indian subcontinent.
Abstract: A new species of Gomphidia Selys, 1854 is described from southern Western Ghats, India based on a male specimen. The new species is very distinct from all the known species of Gomphidia from Indian subcontinent. Revised keys to the males and known females of Gomphidia of India and Sri Lanka are provided.
TL;DR: Comparison to extant taxa shows that the larvae are to be assigned to the clubtails (Gomphidae), namely to the genera Gomphidia or Ictinogomphus, or, more unlikely, Diastatomma in the subfamily Lindeniinae, and thus constitute the first record of larvae of this subfamily in the Oligocene.
TL;DR: Previously, a total of 57 species of Odonata were reported from the Asansol-Durgapur Industrial Area, India, and in this present attempt the author reports an additional six species occurring from the same region, with one of them belonging to the Aeshnidae family.
Abstract: Previously, a total of 57 species of Odonata were reported from the Asansol-Durgapur Industrial Area, India. In this present attempt the author reports an additional six species occurring from the same region. Among six of the species were found between January 2016 and September 2019, with one of them belonging to the Aeshnidae family, two to the Gomphidae family, two to the Libellulidae family, and only one damselfly from the Lestidae family. The species Gomphidia leonorae Mitra, 1994 has been reported in this paper for the second time from West Bengal, India, after a gap of 23 years, from Durgapur Barrage, which is situated at the end point of the study area.
TL;DR: Three stadium larvae of Gomphidia bredoi, G. gamblesi and G. quarrei are presented, based on exuviae collected in Ivory Coast, Cameroon, Kenya and Namibia, and can be separated by the presence/absence and shape of an abdominal dorsal spine on segment 9.
Abstract: Descriptions and illustrations of the final stadium larvae of Gomphidia bredoi, G. gamblesi and G. quarrei are presented, based on exuviae collected in Ivory Coast, Cameroon, Kenya and Namibia. The three species can be separated by the presence/ absence and shape of an abdominal dorsal spine on segment 9, by the numbers of abdominal lateral spines and by several characteristic processes on the head.
