Cladotanytarsus Kieffer (Diptera: Chironomidae): several distinctive species reviewed on the basis of records from Canada and USA Author Puchalski, Mateusz Author Giłka, Wojciech text Zootaxa 2017 4242 2 344 358 journal article 36303 10.11646/zootaxa.4242.2.7 8632c8ac-22fd-42bc-b95c-820c0c029c20 1175-5326 376427 8511A4B8-D82F-49EE-9132-E941B4C5D2C4 Cladotanytarsus conversus (Johannsen) ( Fig. 5 A, B) Tanytarsus conversus Johannsen, 1932 : Johannsen 1932 : 543 (adult male and female, Sumatra ). Cladotanytarsus conversus ( Johannsen, 1932 ) : Langton & Garcia 2000 : 199 (adult male and female, pupa, larva; South Asia ; Europe: France , Greece ). Cladotanytarsus tobaquardecimus Kikuchi et Sasa, 1990 : Kikuchi & Sasa 1990 : 314 (adult male, Sumatra ), syn. nov. Material examined. BULGARIA . Danube , Svishtov , 17 September 2007 , 16 males , leg. Wolfram Graf (ex coll. B. Janecek , deposit in DIZP ) . Holotype of Cladotanytarsus tobaquardecimus , adult male slide-mounted (No. 200:070): 5 photographs (slide + abdomen + hypopygium magnified) displayed on the NMNS website. Remarks. This widely distributed species is known from Indonesia in the south-east through Thailand and India to Europe in the north-west ( Langton & Garcia 2000 ). With regard to the structural variations of the male hypopygium ( cf. Fig. 5 A & B, Langton & Garcia 2000 , figs 1 & 2, Kikuchi & Sasa 1990 , fig. 20 and NMNS , photographs of the holotype ), body colouration and the main metric/meristic characters ( Table 3 ), we found no significant differences between specimens described as Cladotanytarsus conversus and C. tobaquardecimus , both names originally coming from Sumatra . Consequently, we propose to treat them as synonyms.
