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.
