Integrative taxonomy confirms two new West-Palaearctic species allied with Chrysotoxum vernale Loew, 1841 (Diptera: Syrphidae)

The taxonomy of the syrphid genus Chrysotoxum Meigen, 1803 (Diptera: Syrphidae), is complex and currently under scrutiny. Two new species allied with Chrysotoxum vernale , one from the Western Mediterranean, Chrysotoxum hispanicum sp. n. and the other from the Eastern Mediterranean, Chysotoxum anato...

Description
Summary:The taxonomy of the syrphid genus Chrysotoxum Meigen, 1803 (Diptera: Syrphidae), is complex and currently under scrutiny. Two new species allied with Chrysotoxum vernale , one from the Western Mediterranean, Chrysotoxum hispanicum sp. n. and the other from the Eastern Mediterranean, Chysotoxum anatolicum sp. n., are described and illustrated. Chrysotoxum hispanicum sp. n. is distinguished from the similar C. vernale Loew by the size of the yellow abdominal fasciae and shape of surstyli. Chrysotoxum anatolicum sp. n., known only from females, possesses an almost entirely yellow-pigmented wing, unusual amongst the other studied species of the C. vernale group. Additionally, C. hispanicum sp. n. and C. anatolicum sp. n. are separated from each other, as well as from other species of the C. vernale group by COI and ITS2 gene markers. An identification key to the West Palaearctic species of the C. vernale group is provided.
