Revision of the Japanese Ablabesmyia (Diptera: Chironomidae: Tanypodinae), with descriptions of three new species Author Niitsuma, Hiromi text Zootaxa 2013 3664 4 479 504 journal article 10.11646/zootaxa.3664.4.4 39399033-6847-442b-9d34-d01014510f00 1175-5326 223656 46384FDA-C328-4A6C-A45F-F60C09410D25 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.
