Natarsia tokunagai (Fittkau)

(Figs. 3–4)

Natarsia tokunagai (Fittkau, 1962: 114) (as Macropelopia); Kobayashi and Niitsuma (1998: 133–134).

Krenopelopia kurobefasciata Sasa et Okazawa, 1992a: 63 –64, Fig. 23. [Holotype 233: 091.] Syn. nov.

Zavrelimyia inawaquerea Sasa, Kitami et Suzuki, 2000: 22 –23, Fig. 21 a–k. [Holotype 387: 013.] Syn. nov.

The following characteristics of the holotypes of Krenopelopia kurobefasciata and Zavrelimyia inawaquerea show that they do not belong in Krenopelopia Fittkau or in Zavrelimyia Fittkau, but in the genus Natarsia Fittkau: costal extension well developed (short in Krenopelopia; absent in Zavrelimyia); fore tibial spur with main tooth half as long as spur length and with 8–9 lateral teeth (with main tooth slender, two-thirds of spur length and with 3–4 lateral teeth in Krenopelopia (Fig. 4); semilyrate in Zavrelimyia); fore tibial comb present (absent in Krenopelopia and Zavrelimyia); tergite IX without posterior row of transverse setae (with row of setae in Krenopelopia and Zavrelimyia).

The holotypes of both K. kurobefasciata and Z. inawaquerea have a dark spot around RM (Fig. 3) and abdominal tergites I–VII with a narrow anterior dark band. Both thus are junior synonyms of Natarsia tokunagai (Fittkau) .
