Derostenus parviclava Thomson, 1878:272-273. Neotype female in GNM, designated here.

Asecodes parviclava (Thomson), Bouček and Askew (1968: 131).

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

Diagnosis.

Forewing ( Figs 4, 9 ) with speculum closed posteriorly by a setal line, bare just behind marginal vein and otherwise relatively sparsely setatose; propodeal callus with 2 setae (as in Fig. 23 ).

Hosts and sex ratio.

The Swedish specimens were reared from Galerucella calmariensis and Galerucella pusilla ( Coleoptera : Chrysomelidae )on Lythrum salicaria , and Galerucella tenella on Filipendula ulmaria . The number of samples is smaller than for the other two species (n = 23, 10 from Galerucella calmariensis , 6 from Galerucella pusilla , 7 from Galerucella tenella ). Ratio female/male: 2.09 ±1.16/0.91± 0.95.

Material examined.

TYPE MATERIAL: Neotype female of Derostenus parviclava (GNM). ADDITIONAL MATERIAL: HUNGARY: Vas Co. 1♀ (BMNH); SWEDEN: Skåne 21♀ 16♂(CH, LUZM); Uppland 48♀ 21♂(24♀ 8♂from Galerucella calmariensis , 10♀ 8♂from Galerucella pusilla , 14♀ 5♂from Galerucella tenella ) (BMNH, CH, NHRS); Västergötland 14♀ 5♂(CH, LUZM).
