A new species of phytotelma-breeding dragonfly, ''[[Lyriothemis abrahami]]'' sp. nov., is described from the Western Ghats of Peninsular [[Inde|India]]. The new taxon was previously misidentified as ''[[Lyriothemis flava]]'' Oguma, 1915 ( = ''Lyriothemis tricolor'' Ris, 1916). In contrast to ''[[Lyriothemis flava]]'', the new species is sexually dimorphic, with males easily identified based on the characteristic shape of the hamules. Females are identified by their jet- black and yellow colour with triangular yellow streaks on the dorsum of the abdomen and the distinct triangular shape of the vulvar lamina. Photographs of mature adults, tenerals, hamules, illustrations of vesica seminalis, vulvar lamina, and a key to ''[[Lyriothemis]]'' of the Indian subcontinent are provided. | A new species of phytotelma-breeding dragonfly, ''[[Lyriothemis abrahami]]'' sp. nov., is described from the Western Ghats of Peninsular [[Inde|India]].

Sadasivan K. & al. 2025 - A new species of Lyriothemis Brauer, 1868 (Odonata, Libellulidae) from the Western Ghats of Peninsular India. - Entomon, 50 (2) (art. n°50212) : 213-234. - [A traiter !]
Résumé (traduction libre)
Une nouvelle espèce de libellule se reproduisant en phytotelme, Lyriothemis abrahami sp. nov., est décrite dans les Ghâts occidentaux de la péninsule indienne. Le nouveau taxon avait auparavant été identifié à tort comme Lyriothemis flava Oguma, 1915 (= Lyriothemis tricolor Ris, 1916). Contrairement à Lyriothemis flava, la nouvelle espèce présente un dimorphisme sexuel, les ♂ étant facilement identifiables grâce à la forme caractéristique de leurs hamules. Les ♀ se distinguent par leur couleur noir de jais et jaune, avec des stries triangulaires jaunes sur le dos de l'abdomen et la forme triangulaire distincte de la lamina vulvaire. Des photographies d'adultes matures, de ténéraux, d'hamuli, des illustrations de la vesica seminalis, de la lamina vulvaire et une clé pour identifier les Lyriothemis du sous-continent indien sont fournies.

The new taxon was previously misidentified as Lyriothemis flava Oguma, 1915 ( = Lyriothemis tricolor Ris, 1916). In contrast to Lyriothemis flava, the new species is sexually dimorphic, with males easily identified based on the characteristic shape of the hamules. Females are identified by their jet- black and yellow colour with triangular yellow streaks on the dorsum of the abdomen and the distinct triangular shape of the vulvar lamina. Photographs of mature adults, tenerals, hamules, illustrations of vesica seminalis, vulvar lamina, and a key to Lyriothemis of the Indian subcontinent are provided.
