She recognized seven species of Chironomus (s.s) but sent me fixed larval material of only four of these which she tentatively identified as C. apicatus Johannsen 1932, C. costatus Johannsen 1932, C. javanus Kieffer 1924, and C. stupidus Johannsen 1932. She sent fixed larvae to me for confirmation of her identifications, but died before I was able to determine accurate identities from morphology alone. With additional comparative material, along with polytene chromosome banding patterns and DNA barcode sequence from the mitochondrial COI gene, the species have been identified as a form of C. flaviplumus (auct, not Tokunaga)(here called C. flaviplumus Type B), C. circumdatus Kieffer 1916, probably C. striatipennis Kieffer 1910, and Kiefferulus barbatitarsis (Kieffer 1911), respectively. The identification of one species as a form of C. flaviplumus required an assessment of the present state of knowledge of this species where the name has been applied to at least five different species. Determination of a valid name for this species is not currently possible. The confusion of species identification is an indication that there are a number of closely related species which constitute a “C. flaviplumus group”.","PeriodicalId":30852,"journal":{"name":"CHIRONOMUS Journal of Chironomidae Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49098185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each is described as Nilotanypus haplochelus new species and Nilotanypus ctenochelus new species respectively. Morphological differentiation is stronger in the larva and pupa, with adult stages less well differentiated, as seems usual in the genus. Both species are distributed widely across the Australian continent, but seemingly absent from offshore islands and Tasmania. A tendency towards lotic psammophily (sand-dwelling) is evident, with sympatry at some tropical / subtropical locations. Additional molecular data from non-Australian taxa indicates that N. ctenochelus is sister to all other sampled taxa and N. haplochelus to an undescribed species from oriental China. Review of all stages of several non-Australian species requires revised generic diagnoses, and, critically, recognition of Pentaneura comata Freeman 1953 as synonymous with the type of the genus, Nilotanypus remotissimus Kieffer 1923 (new synonym).","PeriodicalId":30852,"journal":{"name":"CHIRONOMUS Journal of Chironomidae Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48606163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
