Synonymic notes on some species of Chironomidae (Diptera) described by Dr. M. Sasa (†) Author Kobayashi, Tadashi Author Endo, Kazuo text Zootaxa 2008 1712 49 64 journal article 10.5281/zenodo.180948 352c3545-b8fa-4547-8cea-9bd78b990a22 1175-5326 180948 Paramerina divisa (Walker) ( Figs. 5–6 ) Paramerina divisa ( Walker, 1856: 192 ) (as Chironomus ); Fittkau (1962: 332–333) .

Krenopelopia amaminova , K. togavicea , and K. yunouresia do not belong to Krenopelopia Fittkau , but to Paramerina Fittkau , since they all possess the following characters (features of Krenopelopia 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 ); 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 ). 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 .
