Ferrington Jr, Leonard C. & Saether, Ole A., 2011, A revision of the genera Pseudosmittia Edwards, 1932, Allocladius Kieffer, 1913, and Hydrosmittia gen. n. (Diptera: Chironomidae, Orthocladiinae) 2849, Zootaxa 2849 (1), pp. 1-314 : 241

Pseudosmittia tokaraneoa Sasa et Suzuki

( Fig. 90 A–B ).

Pseudosmittia tokaraneoa Sasa et Suzuki, 1995: 278 ; Yamamoto 2004: 89; Saether 2006: 44.

Pseudosmittia famikelea Sasa, 1996: 60 ; Yamamoto 2004: 87.

Material examined: JAPAN: Kagoshima Pref., Tokara Islands, Kuchinoshima , holotype male, 10.v.1994, H. Suzuki (NMST No. A 287: 42) ; paratypes 2 males as holotype (NMST No. A 287: 43, 44); Honshu, Toyama Pref., Kureha Hill , holotype male of P. famikelea , 24.viii.1993, (NMST No. A 254: 81) ; paratype male of P. famikelea , as holotype (NMST Nos. A 254: 82

Diagnostic characters: The nearly cuneate wing ( Fig. 90 A ) with postcubital fork, weak inferior volsella ( Fig. 90 B ), curved gonostylus, conspicuous crista dorsalis and very long U-shaped virga separate the male imago from all other Pseudosmittia .

The species is redescribed by Saether (2006). In some parsimony searches the species often fall in the gracilis group, primarily based on the long virga which, however, is of a very different shape from the members of that group.

Distribution

The species is known only from Tokara Islands and Honshu, Japan.
