Asecodes lucens (Nees), Graham (1993: 227).

Diagnosis.

Forewing ( Figs 6, 8 ) with speculum closed posteriorly by a setal line, setose just behind marginal vein and otherwise relatively densely setose; propodeal callus with 2 setae ( Fig. 23 ).

Hosts and sex ratio.

All Swedish specimens were reared from Galerucella sagittareae ( Coleoptera : Chrysomelidae ) on Lysimachia thyrsiflora , Lysimachia vulgaris , and Potentilla palustris . The sex ratio of each clutch is female biased. Ratio female/male (n = 48): 4.27 ±1.83/0.92± 0.94.
