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 : 250-252

Ablabesmyia (Ablabesmyia) amamisimplex Sasa

( Figure 2A )

Ablabesmyia amamisimplex Sasa, 1990: 134 .

? Ablabesmyia longistyla [nec Fittkau, 1962]: Wang, 2000: 631 partim.

Ablabesmyia (Ablabesmyia) amamisimplex: Niitsuma 2013: 487 .

Remarks. The everted aedeagal complex ( Fig. 2A ) clearly shows the shape of the lateral lobe, which is a palmate membranous lobe and looks like a broad lanceolate membrane with lateral or apical teeth in normal position ( Niitsuma 2013, fig. 28).

Wang (2000: 631) recorded a larva of Ablabesmyia longistyla (Fittkau) from Liaoning Province in Palaearctic China. After the reexamination of the material, the second author suspected that it may be the larva of A. (A.) amamisimplex , because the basal segment of maxillary palp is sub-divided into four parts and the basal segment of antenna is more than 15 times as long as the basal width, which are consistent with description given by Niitsuma (2013). Indeed, A. (A.) amamisimplex is common in Palaearctic Japan and has been misidentified as A. (A.) longistyla by Japanese authors, Sasa et al. (1998), Kobayashi & Kubota (2002) and Niitsuma (2005).

Although the species has been known from Palaearctic and Oriental Japan ( Niitsuma 2013), we add new distribution records in Oriental China.
