Diagnosis.
Body weakly polished. Inner orbits almost parallel in females, weakly divergent downward in males. Antenna with 22-24 flagellomeres in females, 22-25 in males. Propodeum without rugae (Fig. 3D View Figure 3 ), without carinae except for anterior part of pleural carina. T I entirely coriaceous, rectangular in dorsal view (Fig. 9G View Figure 9 ). Latero-median carina of T I present basal ca. 0.5 of T I. Face black with a large yellow median spot in females (Fig. 3B View Figure 3 ), entirely yellow in males (Fig. 3F View Figure 3 ). Lateral aspect of pronotum black with ventral and posterior yellow spots in females (Fig. 3A View Figure 3 ), black with yellow ventral and posterior areas in males (Fig. 3E View Figure 3 ). Mesopleuron entirely black in females (Fig. 3A View Figure 3 ), black with a large yellow marking, it enlarged anteriorly in males (Fig. 3E View Figure 3 ). Shoulder marks of mesoscutum yellow in both sexes (Fig. 3C, E View Figure 3 ). Scutellum black with an apical yellow spot in both sexes (Fig. 3C View Figure 3 ). Hind coxa entirely orange in females (Fig. 3A View Figure 3 ), yellow with brown base in males (Fig. 3E View Figure 3 ). Hind trochanter yellow in females (Fig. 3A View Figure 3 ), yellow with a brown dorsal spot in males (Fig. 3E View Figure 3 ). Metasoma entirely black in females, bases of T III and T IV each with a transverse yellow band in males.
Distribution.
Japan (Hokkaido, Honshu, Shikoku, and Kyushu). Outside Japan, this species is widely distributed in Holarctic, Oriental, Oceanic, and Neotropical region ( Yu et al. 2016).
Bionomics.
In Japan, one hover fly species, Episyrphus balteatus (De Geer, 1776) is recorded as a host ( Uchida 1957).
Remarks.
No additional specimen of this species from Japan was found in this study. Some or all previous records of this species from Japan may be based on misidentification of W. biguttatus .
