Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae) Author Jaschhof, Mathias Author Spungis, Voldemars text Zootaxa 2018 4422 1 85 103 journal article 29151 10.11646/zootaxa.4422.1.5 ea160d3a-63f4-4a24-b4b1-042ef1508b5c 1175-5326 1455505 D167DDAD-17D0-4F35-9873-85B4BC7E8FEB Dicerura penttineni Jaschhof & Spungis sp. nov. Figs 3–5 Diagnosis. The gonostylus of D. penttineni , another species of the iridis group, is narrowly rounded apically, bulbous medially, and provided with a small, subglobular lobe mediobasally that is covered with dense, conspicuously large microtrichia, a few setulae and 2–3 short bristles ( Fig. 3 , ↓1). Of the gonocoxites, the ventral emargination is conspicuously shallow and angular-shaped ( Fig. 3 , ↓2) and the two pairs of processes on either side of the emargination are same size. The cap-like apex of the tegmen, which is pointed, has a single pair of small barbs laterally ( Fig. 5 , ↓3). The apical fork of the ejaculatory apodeme is one fourth as long as the apodeme’s total length ( Fig. 5 ). The ninth tergite is strongly tapered towards the apex, which is bilobed and covered densely in short, thick microtrichia ( Fig. 4 , ↓4). The genitalia of D. penttineni closely resemble that of D. triangularis , a species differing in that the gonostylar lobe is flat and angular, the dorsolateral pair of gonocoxal processes is larger, and the ventral gonocoxal emargination is rounded ( Jaschhof & Jaschhof 2013: fig. 59 ). Other male characters. Body length 3.3 mm . Head. Eye bridge 4–5 ommatidia long dorsally. Antenna slightly longer than body; scape and pedicel lighter than flagellum. Circumfila with 1 rather short extension. Neck of fourth flagellomere 1.8 times longer than node. Palpus 4-segmented, as long as head height. Thorax. Scutum with dark stripes dorsally and laterally. Anepisternum with 5–6 setae. Wing as long as body, with brownish tinge. M1+2 reduced to short remnant apically. Legs. Empodia rudimentary. Claws slightly bent, 4 basal teeth gradually decreasing in size. Genitalia. Ninth tergite: setae of various lengths dispersed over entire surface; anterior edge straight, faintly contoured ( Fig. 4 ). Gonocoxites sparsely setose ventrally; dorsal portions protruding, slightly angular-shaped posteriorly; dorsal apodemes moderately long ( Fig. 3 ). Gonostylus twice longer than broad, apex slightly curved, lateral setae larger than medial setae ( Fig. 3 ). Ejaculatory apodeme slightly thickened on basal half ( Fig. 3 ). Etymology. This species is named after the Finnish biologist Jouni Penttinen (Kuopio, Finland ), who, earlier in the present century, worked on the taxonomy and faunistics of Finnish Porricondylinae . As a lasting proof of his talent and enthusiasm as a taxonomist, he left a rich collection of well-prepared specimens, which includes several new, yet unnamed species. Type material. Holotype .
