Abstract
Choroterpes (Euthraulus) kanagae sp. nov. is described based on larvae and male imago, collected from the River Cauvery, Karnataka, India. The new species is differentiated from other known species of the subgenus Euthraulus Barnard, 1932 by the following combination of characters: posterior margin of abdominal terga I-VII with a dark brown band; tergalius I absent; dorsal lamella of tergalius VII with two terminal processes; costal projection of hind wing acute; segment I of gonostylus slender without inner-apical angle; penis slender, elongated, little longer than ½ of gonostylus length. Comparison of larvae and male imaginal characters of known species of Indian Choroterpes (Euthraulus) are provided. Mitochondrial cytochrome oxidase subunit I (COI) gene was amplified from larva and adult, and compared with published sequences of related species.
期刊介绍：
Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
