Ablabesmyia (Karelia), Roback

Niitsuma, Hiromi & Tang, Hongqu, 2019, Taxonomic review of Ablabesmyia Johannsen (Diptera: Chironomidae: Tanypodinae) from Oriental China, with descriptions of six new species, Zootaxa 4564 (1), pp. 248-270 : 266

Subgenus Karelia Roback

Karelia Roback, 1971 : 357, 1985: 169; Niitsuma 2013: 496. Type species: Tanypus illinoensis Malloch , by original designation.

In the subgeneric diagnosis for the adult, Roback (1985: 169) wrote, “LL of aedeagus absent”. However, the males of A. (Karelia) kisanganiensis , A. (Karelia) makarchenkoi Niitsuma , A. (Karelia) lata Niitsuma and A. (Karelia) perexilis Niitsuma possess distinct lateral lobes (see Lehmann 1981, Abb. 5 for the first species; Niitsuma 2013, figs 54, 66, 69 for the remaining species). The male of A. (Karelia) daiensis sp. n. described below has a compact group of filaments in the same position where the lateral lobe would be normally found next to the aedeagal blade, the group then merges with rows of lateral filaments that continue and reach the basidorsal lobe. Although it is difficult to indicate the boundary between the filament group and the lateral filaments, the filament group may be homologous to the lateral lobe.
