Diagnosis. In Korea, only X. abiens , X. orientiflorum sp. n. and X. tarda share a light colored abdominal pattern in dark background, by which they can be separated from any other Korean Xylota species: abdominal terga 2 and 3 each with a pair of orange-yellow maculae ( Fig. 2 View FIGURE 2 P–S). Among these three species, the shape and size of maculae are species specific, and there is no problem distinguishing one another. Xylota tarda do have the largest maculae almost touching each other ( Figs 2R, S View FIGURE 2 , 6O, P View FIGURE 6 ). The other two species have smaller maculae, but maculae on tergite 3 are more or less square in X. abiens ( Figs 2P View FIGURE 2 , 3A View FIGURE 3 ) but widely rectangular in X. orientiflorum sp. n. ( Figs 2Q View FIGURE 2 , 5O View FIGURE 5 ). In addition, the latter species can be further separated by having the area anterior to ocellar triangle (vertical triangle anterior to ocellar triangle in male, and small area immediately anterior to ocellar triangle in female) covered with yellowish pile ( Fig. 1Q View FIGURE 1 ) while the other two species do not have pile on that area ( Fig. 1P View FIGURE 1 , R–U). The latter species also has black pile on scutal area anterior to wing base, while others have yellow pile.
Description of Korean material. MALE. Body length 8.8–9.0mm; wing length 6.1–7.3mm; dark brown to black species with orange-yellow abdominal maculae ( Figs 2P View FIGURE 2 , 3A View FIGURE 3 ). Head black; face with dense yellow pollinosity ( Fig. 3D, E View FIGURE 3 ); frons anterior to eye contiguity with dense yellow pollinosity ( Figs 1P View FIGURE 1 , 3D, E View FIGURE 3 ); area anterior to ocellar triangle (vertical triangle anterior to ocellar triangle) bare but posterior area covered with yellow pile ( Fig. 1P View FIGURE 1 ). Thorax entirely black; scutum subshiny black with appressed short yellow pile, but posterior half sparsely with longer erect yellow pile mixed with short pile; anterior anepisternum covered with yellowish white pollinosity; posterior anepisternum with yellow pile and yellowish white pollinosity; anepimeron covered with yellow pile; katepisternum moderately covered with yellowish white pollinosity, dorsal posterior area with yellow pile; notopleuron with yellow pile; scutal area anterior to wing base with yellow pile; postalar callus with yellow pile; metasternum bare with white pollinosity. Wing hyaline except for brown pterostigma ( Fig. 3A View FIGURE 3 ); halter yellowish white. Legs: femora almost entirely dark brown to black; pro- and mesotibiae yellow with subapico-ventral 3/5 dark brown; pro- and mesotaromeres 1–3 yellow; pro- and mesotaromeres 4 and 5 brown; metatrochanter ventrally with short calcar (subequal to basal width) ( Fig. 3B View FIGURE 3 ); apico-ventral 1/3 of metafemur with two carinae covered with spinose setulae, remaining ventral area with few spinose setae, antero-dorsally and postero-ventrally with long yellowish white pile, apico-dorsal 1/3 with short black pile; basal 1/3 of metatibia yellow ( Fig. 3B View FIGURE 3 ); metataromeres 1–3 dark brown and 4 and 5 black ( Fig. 3B View FIGURE 3 ). Abdomen about 2.5x longer than wide ( Figs 2P View FIGURE 2 , 3A View FIGURE 3 ); terga 2 and 3 more or less parallel-sided; preabdominal terga dark brown in ground color; tergum 2 medially with a pair of orange-yellow and relatively small subrhombic maculae, separated from each other roughly by 1/3 of each macula width; tergum 3 with a pair of orange-yellow subsqure maculae, separated from each other by about 1/3 of each macula width ( Figs 2P View FIGURE 2 , 3A View FIGURE 3 ). Male genitalia ( Figs 8 View FIGURE 8 A–D, 13E): surstylus with dorsal lobe about twice as long as ventral lobe, long finger shaped and slightly bent ventrally in lateral view, densely covered with spinose setulae ( Fig. 8A, B View FIGURE 8 ); ventral lobe of surstylus widely bulged, apically with scattered short setulae ( Fig. 8A, B View FIGURE 8 ); cercus cordate in profile with long pale pile ( Fig. 8A, B View FIGURE 8 ); lingula indistinct ( Fig. 13E View FIGURE 13 ); fenestra small and elliptic in outline ( Fig. 8A, B View FIGURE 8 ); spur of superior lobe reduced ( Fig. 13E View FIGURE 13 ); superior lobe asymmetrical ( Fig. 8A, B View FIGURE 8 ); each lateral arm of theca apico-dorsally with 4 thorny projections ( Fig. 8A, B View FIGURE 8 ); aedeagus with ejaculatory hood medially with furrow in postero-ventral view, dorsally round in lateral view ( Fig. 8C View FIGURE 8 ); ejaculatory process short ( Fig. 8C View FIGURE 8 ); ejaculatory apodeme apically enlarged and bowl shaped.
FEMALE. Not examined. Bartsch et al. (2009) indicated that European female of this species has frons with a distinct pollinose fascia, the posterior margin of which is straight.
