Pegomya furva

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 : 59

The Pegomya furva species group

This species group includes only two species, Pegomya furva Ringdahl and P. circumpolaris Ackland & Griffiths , both with Holarctic and extensively overlapping distributions. They are poorly differentiated morphologically and were only recently recognized as two species based on small differences in the male terminalia.

Species of the Pegomya furva species group may be separated from the very similar species of the Pegomya fulgens species group as follows: Aristal pubescence shorter in both sexes, no longer than greatest basal diameter of arista; male sternite V ( Figs 13‒15 ) different, more resembling that of the Pegomya tabida species group ( Figs 28‒36 ); male hind femur without a pv seta on middle third; female mid and hind tarsi with dense ventral sensilla widened at tips ( Fig. 5); and oviscapt shorter ( Fig. 66 ). Females as a rule with pair of interfrontal setae fully developed.
