Euplectrus maculiventris Westwood

Figures 14, 30-32, 50

Euplectrus maculiventris Westwood, 1832:128. Lectotype female in OUMNH, examined. Combined to Eulophus by Haliday (1842:plateJ); synonymized with E. bicolor by Bouček and Askew (1968:14); revalidated by Zhu and Huang (2002:134).

Material

(249♀ 200♂). Finland: 15♀ 8♂ (VV), 153♀ 121♂ (MZH, MZLU, ZSM), this material includes 11♀ 4♂ from Agrotis segetum, 5♀ from Eurois occulta, 4♀ from Lithomoia solidaginis; France : 22♀ 9♂ (NHM); Spain: 1♀ 2♂ (MZLU, NHM); Sweden: 35♀ 43♂ (MZLU, NHM), this material includes 6♂ from Mniotype satura; United Kingdom : 23♀ 17♂ (NHM).

Diagnosis.

Female with clypeal area pale, and with pale colour drawn out towards eye and almost reaches eye but with part below the eye dark (Fig. 30), male with entire frons below level of toruli pale and with parts lateral to toruli pale (Fig. 31); female with reticulation on scutellum with isodiametric meshes (Fig. 50), reticulation usually strong but there is some variation in this and some specimens have weak reticulation; male scape 2.8-3.0 × (mean 2.86, n=10) as long as wide (Fig. 14). Similar to E. bicolor, including the narrow posterior part of midlobe of mesoscutum, but can be distinguished from this species through the colour of lower face (both sexes) - pale area confined to clypeal region in E. bicolor, and through the reticulation on the scutellum (females only) - meshes elongate in E. bicolor . Males are similar to males of E. geometricida, but can be distinguished through the relatively long and slender scape.

Hosts.

Agrotis segetum (Denis & Schiffermüller), Eurois occulta (L.), Lithomoia solidaginis ( Hübner), Mniotype satura (Denis & Schiffermüller). All records are from caterpillars of the Noctuidae .

Distribution.

United Kingdom (Westwood 1832), Finland, France, Spain, Sweden (new/confirmed records).

Genetic data.

The single barcoded specimen of E. maculiventris was assigned a distinct BIN and shows a distance of 11.3% to the next neighbour species, E. bicolor (Fig. 63).
