70208787E42B4F33FEC8FA41FE3E065B.taxon	diagnosis	Diagnosis This species can be readily distinguished from other members of the Volucella pellucens group by its longer abdominal tergite 2 (longer than tergite 3, or at most 2.4 x wider than long; Figs. 5 A, C). Males can be further differentiated by their basoflagellomeres in lateral view slightly constricted in middle (Fig. 1 C) and the surstyli greatly shortened in lateral view (Figs. 1 G, H).	en	Choi, Deuk-Soo, Ôhara, Kenji, Han, Ho-Yeon (2006): Taxonomic notes on the Volucella pellucens species group (Diptera: Syrphidae) with a description of one new species from the Eastern Palaearctic.

70208787E42B4F33FEC8FA41FE3E065B.taxon	discussion	Remarks We have occasionally found this species mixed with V. pellucens tabanoides specimens under same identification labels in the Korean institutions. These two species superficially resemble each other, but the new species is easily separable by the longer abdominal tergite 2 in both sexes, and much darker vertex in female. Further examination of the male genitalia strongly suggests that this species might not even be closely related to V. pellucens. The male genitalic structures (especially the highly reduced surstyli; Figs. 1 G, H) are so unique that we were not able to associate the new species with any other Volucella species. We are currently investigating this matter using both morphological and molecular data (Choi et al., in prep.). Our preliminary analysis based on mitochondrial 16 S rRNA and COII gene sequences suggests that V. thompsoni n. sp. might be more closely related to V. nigropicta (the zonaria species group) than the other species of the pellucens species group.	en	Choi, Deuk-Soo, Ôhara, Kenji, Han, Ho-Yeon (2006): Taxonomic notes on the Volucella pellucens species group (Diptera: Syrphidae) with a description of one new species from the Eastern Palaearctic.

70208787E42F4F3DFEC8FAD3FE580163.taxon	diagnosis	Diagnosis This species can be readily distinguished from other members of the Volucella pellucens group by the yellowish brown apexes of femora, bases of tibiae, and basotarsomeres (Figs. 5 E – H). The pale areas of abdominal tergite 2 look much more yellowish than those of other species (Figs. 5 E, G). Males can be further differentiated by the scutum with brown lateral margins (Figs. 5 E, F) and the eyes slightly separated (Figs. 2 A, B).	en	Choi, Deuk-Soo, Ôhara, Kenji, Han, Ho-Yeon (2006): Taxonomic notes on the Volucella pellucens species group (Diptera: Syrphidae) with a description of one new species from the Eastern Palaearctic.

70208787E4224F3FFEC8F98AFC9D0446.taxon	diagnosis	Diagnosis Volucella pellucens and V. thompsoni are similar in having almost entirely pale abdominal tergite 2, with which they can be readily distinguished from the other species of the V. pellucens species group. Volucella thompsoni can be further separated from V. pellucens by the diagnosis already given. We found that there are clear differences between the Far Eastern and European subspecies of V. pellucens especially in females (see also Remarks of V. p. tabanoides). Females of V. p. tabanoides can be distinguished from those of V. p. pellucens by their scutum with distinct brown triangular prescutella macula (Figs. 6 C, D). Males are hardly separable but their eye contiguity­vertex ratios seem different: 0.54 – 0.67 in V. p. tabanoides (89 specimens measured), and 0.75 – 1.00 in V. p. pellucens (9 specimens measured) (Table 1).	en	Choi, Deuk-Soo, Ôhara, Kenji, Han, Ho-Yeon (2006): Taxonomic notes on the Volucella pellucens species group (Diptera: Syrphidae) with a description of one new species from the Eastern Palaearctic.

70208787E4244F3BFEC8F9C8FB9801AB.taxon	biology_ecology	Biology This species is associated with Vespa and Vespula species (Hymenoptera) during immature stages. Recently, the larvae of three Volucella species including this species were collected from soil under the nest of Vespula flaviceps lewisii (Cameron) and studied morphologically in Japan (Ôhara, 1985 a).	en	Choi, Deuk-Soo, Ôhara, Kenji, Han, Ho-Yeon (2006): Taxonomic notes on the Volucella pellucens species group (Diptera: Syrphidae) with a description of one new species from the Eastern Palaearctic.

70208787E4244F3BFEC8F9C8FB9801AB.taxon	discussion	Remarks Specific status of this taxon has been confused in the past. Authors have treated it as V. tabanoides, V. pellucens or V. pellucens tabanoides in Eastern Palaearctic region (see synonymy). This is due to the fact that there are subtle but clear differences between Western and Eastern Palaearctic females. Choi (2005 ­ Ph. D. thesis; nomenclatural changes not available) recently suggested the Eastern Palaearctic population as subspecies based on almost identical male genitalic and molecular characters (mitochondrial 16 S rRNA and COII gene sequences). We also have found differences between the Western and Eastern Palaearctic subspecies (see Diagnosis of V. p. pellucens), but we do not believe that they are different species as some earlier authors indicated (Sack, 1931; Shiraki, 1968; Han et Choi, 2001 etc.). Except for the slight differences in the color pattern of female scutum (Figs. 6 A, B vs. 6 C, D) and the male eye contiguity­vertex ratio, they are morphologically indistinguishable. In addition, our molecular sequence data showed that they are genetically very close (3 – 5 / 1,292 differences in 16 S rRNA and 1 – 2 / 766 differences in COII gene) (Choi et al., in prep.). Based on our prior experiences, we believe that this level of difference usually constitutes intraspecific variation. There also is a record of V. pellucens from India and Malaya (Knutson et al, 1975), but we have not seen any Oriental specimens yet. More comprehensive study of the distribution and variation is needed to further understand their subspecific status. According to the original description of V. pellucens var. japonica Matsumura, 1916, it was based on unspecified number of specimen (s) from Sapporo, Japan. The second author (K. Ôhara) had a chance to examine the Matsumura’s collection deposited in HUS, and found that there were three males under the name V. pellucens var. japonica. However, two of them were from Budapest and Sakhalin collected in 1932, and a single male from Sapporo appeared to be the only specimen used by Matsumura in 1916. This assumed holotype is a bit teneral specimen but apparently belongs to V. p. tabanoides based on both its external appearance and genitalic structures. There are three labels associated with the holotype: 1) 5.22 Sapporo Matsum; 2) Type Matsumura; and 3) Volucella japonica Mats. det. FC Thompson, 1980 (Fig. 7 B). In addition, the body length and wing span were listed as 13.5 mm and 30 mm in the original description without indicating any variation, and this may also be viewed as an indirect evidence for the single type.	en	Choi, Deuk-Soo, Ôhara, Kenji, Han, Ho-Yeon (2006): Taxonomic notes on the Volucella pellucens species group (Diptera: Syrphidae) with a description of one new species from the Eastern Palaearctic.
