Pegomya fulgens

Michelsen, Verner, 2015, Taxonomic review of the major larval pests of bolete fungi (Boletaceae) in Europe: The Pegomya fulgens, furva and tabida species groups (Diptera: Anthomyiidae), Zootaxa 4020 (1), pp. 51-80 : 56

The Pegomya fulgens species group

This species group includes only two morphologically poorly differentiated species, Pegomya fulgens (Meigen) and P. transgressa (Zetterstedt) , one western Palearctic, the other boreal Holarctic in distribution. P. transgressa is an exclusively northern species replacing P. fulgens in the subarctic and low arctic parts of Fennoscandia. Surprisingly, the only species found in Iceland is P. fulgens , which suggests that it has been accidentally introduced there.

Species of the Pegomya fulgens species group may in both sexes be separated from the very similar species of the Pegomya furva species group by the slightly longer aristal pubescence; males further differ by the different structure of male sternite V lobes ( Figs 11, 12 ) and the presence of a pv seta on middle third of hind femur; females further differ by the non-expanded tips of the dense ventral sensilla on the mid and hind tarsi, and by the longer oviscapt ( Fig. 64 ). Females as a rule with the pair of interfrontal setae fully developed.
