9E1D954CFFE6966EFF51FDE3D86FFCD7.taxon	diagnosis	Diagnosis. Dicerura jakovlevi differs from the other species of the iridis group in the gonostylus, whose small mediobasal lobe is angular-shaped and markedly bulging (Fig. 1, ↓ 1); the gonocoxites, whose ventroposterior edge is broadly, darkly pigmented (Fig. 1, ↓ 2); and the tegmen, whose basal portion is unusually strongly constricted, thus providing just a narrow base for the broader, cap-like apex (Fig. 1, ↓ 3). See below D. stipator (Figs 25 – 27), which is another member of the iridis group with darkly pigmented gonocoxites. Other male characters. Body length 3.0 mm. Head. Eye bridge 3 – 4 ommatidia long dorsally. Antenna as long as body; scape and pedicel concolorous with flagellum. Circumfila with 1 – 2 rather short extensions. Neck of fourth flagellomere 1.6 times longer than node. Palpus 4 - segmented, 0.8 times the length of head height, third and fourth segments with tendency to merge. Thorax. Scutum with dark stripes dorsally and laterally. Anepisternum with 2 – 3 setae. Wing as long as body, with brownish tinge. M 1 + 2 weak, reduced to short remnants apically and basally. Legs. Empodia rudimentary. Claws slightly bent, 3 – 4 basal teeth gradually decreasing in size. Genitalia. Ninth tergite subtrapezoid, strongly tapered towards apex, with setae of various lengths dispersed over entire surface; anterior edge straight, faintly contoured; posterior edge either truncate (holotype) or slightly concave (paratype), densely covered with short, thick microtrichia (Fig. 2). Gonocoxites: ventral emargination angular, with slightly convex basal edge; ventromedial processes slightly smaller than dorsolateral processes, all with dense, large microtrichia and a few setulae; dorsal portions strongly protruding posteriorly; dorsal apodemes moderately long (Fig. 1). Gonostylus 1.5 times longer than broad, strongly tapered towards apex (Fig. 1). Apex of tegmen broadly rounded, 1 small, sclerotized barb on either side (Fig. 1). Apical fork of ejaculatory apodeme rather small, one fourth as long as apodeme’s total length (Fig. 1).	en	Jaschhof, Mathias, Spungis, Voldemars (2018): Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae).

9E1D954CFFE1966EFF51FC04DE2CF824.taxon	diagnosis	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. M 1 + 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).	en	Jaschhof, Mathias, Spungis, Voldemars (2018): Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae).

9E1D954CFFE1966EFF51FC04DE2CF824.taxon	etymology	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.	en	Jaschhof, Mathias, Spungis, Voldemars (2018): Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae).

9E1D954CFFE0966CFF51FA30DF0DFE40.taxon	diagnosis	Diagnosis. Dicerura yezoensis, a member of the formosa group, is distinguished as follows: the gonostylus has a broadly rounded, not pointed, apex (Fig. 6, ↓ 1); the ventromedial gonocoxal processes are big and subglobular rather than ovate (Fig. 6, ↓ 2); and the posterior edge of the ninth tergite is provided with a pair of pointed, microtrichose lobes (Fig. 7, ↓ 3). Other male characters. Body length 3.3 mm. Head. Eye bridge 3 – 4 ommatidia long dorsally. Antenna clearly shorter than body; scape and pedicel yellowish, lighter than flagellum.

9E1D954CFFE3966DFF51F95DDE5AFD7E.taxon	diagnosis	Diagnosis. The gonocoxites of D. barbata are quite unlike that of all other Dicerura in having an extremely large emargination ventrally, which leaves just a short, asetose intercoxal bridge; the emargination is partly filled with an ovate, microtrichose lobe (Fig. 11, ↓ 1). The large, subtriangular gonocoxal processes are densely microtrichose medially; the dorsal apodemes are conspicuously long and thin (Fig. 11, ↓ 2). The elongate gonostylus has a small side lobe subapicomedially, which is covered apically and dorsally with dense, large microtrichia, a few setulae, and 1 – 2 short bristles (Fig. 10, ↓ 3). The apical fork of the ejaculatory apodeme is perfectly V-shaped (Fig. 12). The elongate, parallel-sided tegmen, which is membranous for the most part, has a broadly rounded apex and a single pair of small, sclerotized processes subapicolaterally (Fig. 12, ↓ 4). The apex of the ninth tergite is bilobed and densely covered with short, thick microtrichia, especially along the edge and on the inside (Fig. 9).	en	Jaschhof, Mathias, Spungis, Voldemars (2018): Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae).

9E1D954CFFED9662FF51FF1DD83FF855.taxon	description	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.	en	Jaschhof, Mathias, Spungis, Voldemars (2018): Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae).

9E1D954CFFED9662FF51FF1DD83FF855.taxon	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).	en	Jaschhof, Mathias, Spungis, Voldemars (2018): Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae).

9E1D954CFFEC9660FF51FF1DD948FE5E.taxon	description	We identified our specimens from sketches made by one of us (MJ) while examining the holotype of D. formosa in 2012. Mamaev’s (1998) description of this species, whose only illustration was a schematic drawing of the gonostylus, is insufficient for specific identification. Dicerura formosa, described originally from southern Siberia, is newly reported here from two additional northern European countries.	en	Jaschhof, Mathias, Spungis, Voldemars (2018): Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae).

9E1D954CFFEC9660FF51FF1DD948FE5E.taxon	diagnosis	Diagnosis. Characters to differentiate D. formosa from the other species of the formosa group are as follows. The slightly bent gonostylus, whose apex is clearly tapered, bears large setae posteriorly and clearly smaller setae medially, the latter intermingled with short, dense microtrichia (Fig. 16, ↓ 1). The ventral gonocoxal emargination is slightly convex basally, reinforced by sclerotization, and bordered by two pairs of gonocoxal processes, of which the ventromedial processes are ovate (Fig. 16, ↓ 2), while the dorsolateral processes are elongate and slightly bent (Fig. 16, ↓ 3). The semicircular collar of the tegmen has 5 inconspicuous, sclerotized knobs (Fig. 18). The ninth tergite is unusual in two different aspects. First, the posterior edge has a small, broadly V-shaped incision (Fig. 17, ↓ 4) that is bordered on the inside by subtriangular, densely microtrichose protuberances, and second, the anterior edge is broadly rounded (convex) and reinforced by sclerotization, not straight and faint as in other Dicerura. Two non-genitalic characters uncommon in Dicerura, which were not mentioned in Mamaev’s (1998) description of D. formosa, are the presence of setae on the anepisternum and the long, sometimes even complete M 1 + 2.	en	Jaschhof, Mathias, Spungis, Voldemars (2018): Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae).

9E1D954CFFEF9661FF51FD8FDBD9FB88.taxon	description	Dicerura furculata is known from a very few specimens collected in Ukraine (Mamaev 1968), Latvia (Spungis 1987), and Finland (Jaschhof et al. 2014). The only Finnish specimen, a male, is depicted here. Spungis (1987) described the female of this species and referred to the larva as known but not yet described. Micrographs of the holotype of D. furculata, which we compared here with the holotype specimen of D. padi, made clear that these two species are identical, rendering D. padi a new junior synonym of D. furculata. Mamaev´s (1975) original description of D. padi, based on specimens of both sexes from the Russian Far East, did not include illustrations and is therefore of little help in the identification of this species.	en	Jaschhof, Mathias, Spungis, Voldemars (2018): Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae).

9E1D954CFFEF9661FF51FD8FDBD9FB88.taxon	diagnosis	Diagnosis. Dicerura furculata is in several respects an unusual, distinctive species. Most importantly, the apex of the ejaculatory apodeme is bifurcate, as is typical of Dicerura, but the two tines of the fork are conjoined by an apparently solid, transparent membrane (Fig. 21, ↓ 1). Furthermore, the tegmen, which is elongate, subrectangular, and membranous posteriorly, lacks any substructures (Fig. 21). The gonostylus, whose outline resembles that in D. barbata (Fig. 10), is slightly bent, 2.5 times longer than broad, and provided with a long, slightly protruding lobe on the inside that bears dense, large microtrichia, a few fine setae but no bristles (Fig. 20, ↓ 2). Of the gonocoxites, the deeply U-shaped ventral emargination is both reinforced by sclerotization and darkly pigmented (Fig. 19, ↓ 3); the dorsoposterior portions appear bilobed due to the strongly projecting medial bridges (Fig. 19, ↓ 4); and the dorsal apodemes are unusually short. The bilobed apex of the ninth tergite is provided with dense, thick microtrichia (Spungis 1987: fig. 3.6).	en	Jaschhof, Mathias, Spungis, Voldemars (2018): Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae).

9E1D954CFFEF9661FF51FD8FDBD9FB88.taxon	discussion	Remarks. As noticed already by Mamaev (1968), D. furculata is unusual among Dicerura in having a short, three-segmented palpus (Spungis 1987: fig. 3.7). Empodia are vestigial and claws are provided with up to three basal teeth. Mamaev´s (1975) statement that the palpus of D. padi would consist of only two segments is not correct; we found three palpal segments in both the male and one of the females (the other remained unstudied) of the original series. We observed some variation in the circumfila of male D. padi: in both the holotype and a specimen from Latvia (Spungis 1987) the extensions of a circumfilum merge posteriorly to form a loop, while in the Finnish specimen studied here both extensions are usually free-ending and only exceptionally looped.	en	Jaschhof, Mathias, Spungis, Voldemars (2018): Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae).

9E1D954CFFEE9661FF51FB3DDE7DF8F5.taxon	diagnosis	Diagnosis. This is the only Dicerura in which the apices of the ejaculatory apodeme are not smooth but appear frayed (Fig. 24, ↓ 1), a detail discernible only at high magnification. Other characters of diagnostic merit are as follows. The gonostylus, which is 2.5 times longer than wide, has a pointed, slightly bent apex and a long mediobasal lobe that is only slightly protruding and provided with dense, large microtrichia, a few setulae, and 5 – 6 short bristles (Fig. 22). The gonocoxites have conspicuously few ventral setae; the ventral emargination is shallow and angular (Fig. 22, ↓ 2); the two pairs of processes bordering the emargination are same size, rounded, and provided with both microtrichia and fine setae; the dorsal portions are angular-shaped posteriorly; and the dorsal apodemes are conspicuously long and thin (Fig. 22, ↓ 3). The apical portion of the tegmen, whose outline is basically semicircular, is truncate to slightly concave on the crest and provided with 4 – 5 inconspicuous barbs on either side (Fig. 24, ↓ 4). The bilobed apex of the ninth tergite is covered with dense, thick microtrichia, especially along the posterior edge and on the inside (Fig. 23).	en	Jaschhof, Mathias, Spungis, Voldemars (2018): Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae).

9E1D954CFFEE9666FF51F8E6D96FFD15.taxon	description	Dicerura stipator, another species found only in the Far East of Russia, is known from two males and one female, all mounted by Mamaev on one and the same microscope slide. Mamaev (1972) did not indicate which of the males is to be regarded as the holotype, so both are referred to here as syntypes. The genitalia of both specimens are partly distorted and collapsed, which is why the gonostylar structure cannot be described here. From what is left of the gonostyli, we assume that their outline is similar to that in D. penttineni (Fig. 3). Mamaev’s (1972) original description of D. stipator, which does not refer to characters of the female and lacks illustrations, is too unspecific for the purpose of identification.	en	Jaschhof, Mathias, Spungis, Voldemars (2018): Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae).

9E1D954CFFEE9666FF51F8E6D96FFD15.taxon	diagnosis	Diagnosis. Dicerura stipator is a typical member of the iridis group. It is the only species of Dicerura in which the two tines of the apical fork of the ejaculatory apodeme are serrate medially (Fig. 27, ↓ 1). Of the gonocoxites, the ventral emargination is wide and shallow; the two pairs of processes bordering the emargination are approximately same size; the ventroposterior edge is broadly pigmented (Fig. 25, ↓ 2); and the dorsal portions are strongly bulging medially. The tegmen of D. stipator, which is generally similar to that of D. penttineni (cf. Fig. 3), has a pair of small, sclerotized barbs and, behind the barbs, short appendages (Fig. 27, ↓ 3); its narrowly rounded apex is reinforced by a roundish, sclerotized knob, which resembles the condition found in D. unidentata. The ninth tergite of D. stipator is again similar to that of D. penttineni (cf. Fig. 4), but the narrow, apical portion, which is darkly pigmented and provided with dense microtrichia on the inside, is larger (Fig. 26).	en	Jaschhof, Mathias, Spungis, Voldemars (2018): Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae).

9E1D954CFFE89664FF51FA0BD915FE18.taxon	description	Spungis (1987) based his description of D. unidentata on three larvae found in Latvia, of which one developed into a male adult. Subsequent records of males of this species are from Finland (Jaschhof et al. 2014) and, as shown here, from Estonia, Slovakia, and Ukraine. The female of D. unidentata remains unknown.	en	Jaschhof, Mathias, Spungis, Voldemars (2018): Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae).

9E1D954CFFE89664FF51FA0BD915FE18.taxon	diagnosis	Diagnosis. Dicerura unidentata is a typical member of the dentata group. Characteristic of the gonocoxites, the ventral emargination is angular-shaped and bordered by small, inconspicuous protuberances with both setulae and large microtrichia (Fig. 28, ↓ 1); around the emargination is a darkly pigmented area. The subrectangular tegmen is 2.5 times longer than broad and provided with 4 – 6 small barbs of various sizes apicolaterally (Fig. 31, ↓ 2). The additional, single barb present at the tegminal apex (therefore the species’s name, unidentata) is in most of the specimens studied here reduced to a roundish, sclerotized knob (Fig. 31, ↓ 3), in other specimens it is untraceable. The subtriangular gonostylus is about 1.5 times longer than broad; the mediobasal lobe is somewhat angular and provided with 5 – 15 short bristles among sparse, large microtrichia (Fig. 30). The apical fork of the ejaculatory apodeme takes up more than one third of the apodeme’s total length (Fig. 31). The apex of the ninth tergite, which is broadly rounded to truncate, is covered with dense, thick microtrichia (Fig. 29, ↓ 4). Species with similar genitalia are D. dentata and D. dispersa. In distinction from D. unidentata, the tegmen of D. dentata is provided with more and slightly larger barbs that together form a saw-blade structure on either side (Jaschhof & Jaschhof 2013: fig. 50 E), while the tegmen of D. dispersa is constricted subapically, not parallel-sided (Jaschhof & Jaschhof 2013: fig. 51 C).	en	Jaschhof, Mathias, Spungis, Voldemars (2018): Towards reliable identification of male Dicerura: descriptions of three new and seven poorly known species in the Palearctic region (Diptera: Cecidomyiidae, Porricondylinae).
