Paramerina divisa (Walker) View in CoL

( Figs. 5–6 View FIGURES 1 – 12 )

Paramerina divisa ( Walker, 1856: 192) View in CoL (as Chironomus View in CoL ); Fittkau (1962: 332–333).

Paramerina kurobekogata Sasa et Okazawa, 1992a: 64 View in CoL , Fig. 24 View FIGURES 13 – 26 . [Holotype 233: 096.] Syn. nov. Paramerina tokararesea Sasa et Suzuki, 1995: 285 View in CoL –287, Fig. 23 View FIGURES 13 – 26 . [Holotype 290: 075.] Syn. nov. Krenopelopia yunouresia Sasa, 1989: 152 View in CoL –153, Plate 4A. [Holotype 052: 023b.]. Syn. nov. Krenopelopia amaminova Sasa, 1990: 138 View in CoL –139, Fig. 26 View FIGURES 13 – 26 . [Holotype 179: 061.] Syn. nov.

Krenopelopia togavicea Sasa et Okazawa, 1992b: 213 View in CoL –214, Fig. 10 View FIGURES 1 – 12 . [Holotype 188: 056.] Syn. nov. Monopelopia okigenga Sasa, 1990: 141 View in CoL –142, Fig. 28 View FIGURES 27 – 31 . [Holotype 174: 094.] Syn. nov.

Krenopelopia amaminova View in CoL , K. togavicea View in CoL , and K. yunouresia View in CoL do not belong to Krenopelopia Fittkau View in CoL , but to Paramerina Fittkau View in CoL , since they all possess the following characters (features of Krenopelopia View in CoL in parentheses): costa ending clearly before end of M1+2 (costa ending beyond M1+2); abdominal tergite IX without row of setae (with row of setae); mid tibial spurs very narrow and elongate, with 2–3 lateral teeth (slender, with 3–4 lateral teeth) ( Fig. 6 View FIGURES 1 – 12 ); some abdominal tergites with dark band (all abdominal tergites without dark band, overall very pale); apodemes distinct, apical part of transverse sternapodeme pointed, phallapodeme long (phallapodeme indistinct) ( Fig. 5 View FIGURES 1 – 12 ).

Monopelopia Fittkau is characterized by the spindle-shaped tibial spurs, single spurs on mid and hind tibiae, short phallapodeme, tergite IX with transverse row of setae, and by lacking R2+3. Monopelopia okigenga has two tibial spurs on mid and hind legs, with main tooth and some lateral teeth, weak R2+3, long phallapodeme, and tergite IX without row of setae. These characters clearly indicate that the species belongs in Paramerina .

According to Fittkau (1962: 327–328) and Pinder (1978: 34), Krenopelopia amaminova Sasa , K. togavicea Sasa et Okazawa , K. yunouresia Sasa , Monopelopia okigenga Sasa , Paramerina kurobekogata Sasa et Okazawa , and P. t o k a r a re s e a Sasa et Suzuki all key to Paramerina divisa (Walker) as they have wing membranes without pigmentation and abdominal tergites II and V almost pale. All six species thus are considered as synonyms of P. divisa .
