Niitsuma, Hiromi, 2013, Revision of the Japanese Ablabesmyia (Diptera: Chironomidae: Tanypodinae), with descriptions of three new species, Zootaxa 3664 (4), pp. 479-504 : 481

Subgenus Ablabesmyia Johannsen

Ablabesmyia Johannsen, 1905: 135 ; Roback 1971: 365, 1985: 178.

Remarks. The subgeneric diagnosis is given by Roback (1971, 1985).

The males of Ablabesmyia s. str. differ from those of other subgenera in the combination of the foretibia with a median band at near central position, and the gonostylus with a megaseta expanded apically.

According to Oliveira et al. (2008), the pupae are separable from those of other subgenera by the aeropyle tube club-shaped on the apex of thoracic horn. However, the Japanese species belonging to Karelia also features the aeropyle tube club-shaped.

Generally the larvae are distinct from those of other subgenera in the maxillary palp with a basal segment subdivided into three or more parts (Oliveira et al. l. c.).

Roback (1985) divided the subgenus Ablabesmyia into five species groups, A. (A.) rhamphe group, A. (A.) monilis group, A. (A.) simpsoni group, A. (A.) mallochi group and A. (A.) aspera group, on the basis of the adult and larval features.
