New and rarely found species of asynaptine Porricondylinae (Diptera: Cecidomyiidae) in northern Europe Author Jaschhof, Mathias Author Jaschhof, Catrin text Zootaxa 2019 2019-05-14 4604 2 281 300 journal article 26833 10.11646/zootaxa.4604.2.3 f5b155f4-c251-4daf-b267-322b95115f91 1175-5326 2807064 0BA07364-39ED-4349-98C5-27431A90CEAA Asynapta taigensis sp. nov. Fig. 4 Diagnosis. This is a typical Asynapta , evidently closely related to both A. baltica and A. rickebasta as the helmetshaped gonostylus and the triangular projections on both sides of the gonocoxal emargination indicate. A peculiarity of A. taigensis is the subapical position of the gonostylar claw, caused by the strong swelling ventroapically ( Fig. 4 , ↓ 3 ). As another distinctive structure, the ventral parameres form a sclerotized V-shape with a small, loop-like appendage at the base ( Fig. 4 , ↓ 4 ). Larvae and females of the new species are unknown. Other male characters. Body size 1.8 mm . Head. Eye bridge 9–10 ommatidia long dorsally. Scape and pedicel lighter than flagellum. Flagellomeres 15 ( holotype ) to 22. Neck of fourth flagellomere 0.8 times the length of node. Palpus 4-segmented, 1.4 times longer than head height. Thorax. Metepisternum non-setose. Wing slightly longer than body, 2.5 times longer than wide. Genitalia ( Fig. 4 ). Gonocoxal synsclerite: ventral emargination U-shaped; ventral bridge almost non-setose; dorsoposterior portions extended into subtriangular lobes. Tegmen twice as long as broad, apex rounded, faintly contoured. Ejaculatory apodeme hardly traceable. Etymology. The species name, taigensis , is an adjective derived from taiga , the Russian word for the boreal coniferous forest where all the specimens known of this species were collected. Type material.
