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 Diamesa sunabacedea (Tanaka et Sasa) , comb. nov. ( Figs. 24–25 ) Diamesa sunabacedea (Tanaka et Sasa, 2001: 45, Fig. 3 a–j) (as Pseudodiamesa ). [ Holotype 350: 024.] In the description of Pseudodiamesa sunabacedea, Tanaka and Sasa (2001) erroneously stated that tarsomere IV is cylindrical. Actually, it is cordiform. Based on the shape of tarsomere IV, presence of inner verticals, and the structure of the hypopygium, the species undoubtedly belongs in Diamesa Meigen. Diamesa sunabacedea is very similar to D. insidiosa described by Serra-Tosio (1983) from Nepal , particularly in the shape of the hypopygium ( Figs. 24–25 ). However, D. sunabacedea has a higher antennal ratio and there are minor differences in the shape of the sternapodeme, basal plate and medial field, which apparently render the two species distinct.
