Chironomus (Chironomus) okinawanus Hasegawa et Sasa, 1987 View in CoL

Chironomus okinawanus Hasegawa et Sasa, 1987: 283 View in CoL .

Chironomus okicontractus Sasa, 1993: 125 View in CoL ; Yamamoto & Yamamoto 2014: 313. [Holotype: male, No. 246:01; holotype missing?].

Chironomus tokarabeceus Sasa et Suzuki, 1995: 258 View in CoL . syn. n.

Specimen examined: Japan: Kagoshima Pref., Tokara Isles , Nakanoshima Is., holotype ♂ of Chironomus tokarabeceus View in CoL , 20. v. 1994, H. Suzuki, [specimen No. 290:001 (NSMT-I-Dip 5010)] .

The following characters are recognized in the holotype of Chironomus tokarabeceus : abdominal tergites 2-6 each with a central dark patch and 3-7 the tergites each with paired dark lines along lateral margins; gonocoxite fused with SIX on its lateral portion. These features are consistent with those of C. okinawanus . We could not examine the holotype of C. okicontractus which has been probably missing. However, we could determine the species as C. okinawanus based on the original description.
