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 foliicola Mamaev, 1968 Figs 13–15 This Far East Russian species is known only from the type series, which consists of two specimens of each sex reared from larvae ( Mamaev 1968 ). With a male body length of two millimeters, D. foliicola is one of the smaller species of Dicerura . The holotype male, which we studied here, is a pale, yellowish specimen with poorly contrasting genitalia; it is therefore possible that we missed inconspicuous substructures of the tegmen or ejaculatory apodeme. FIGURES 13–15. Dicerura foliicola , male, holotype. 13: Genitalia, ventral. 14: Ninth tergite, dorsal. 15: Tegmen and ejaculatory apodeme, ventral. Scales 0.05 mm. Arrows refer to characters described in the diagnosis. Diagnosis. Characteristic of the gonocoxites is a rounded, asetose protrusion at the base of the ventral emargination, which has a glabrous border on either side ( Fig. 13 , ↓1). The medial gonocoxal bridges, which are slightly protruding, are conspicuously densely setose. The gonostylus is characterized by the large medial lobe, which is strongly bulging ( Fig. 13 , ↓2), and the small, narrow apex, which is densely setose ( Fig. 13 , ↓3). The apical fork of the ejaculatory apodeme consists of two lance-shaped rami, which are broader than in other species of Dicerura ( Fig. 15 , ↓4). The tegmen ends in a long, sharp point, which apparently is not an artifact of preparation ( Fig. 15 ). The ninth tergite, whose outline is broad-subtrapezoid, is very slightly concave and densely microtrichose posteriorly ( Fig. 14 ). Material examined. Holotype male (specimen no. P-Di0137 in ZMUM), with the data as specified in the original description ( Mamaev 1968 ).
