EURYTOMA ALOISIFILIPPOI ( RUSSO, 1938)

( FIG. 11A–H )

Decatoma aloisifilippoi Russo, 1938: 175–180 . Original description. Italia: Campania and Sicilia.

Host: Phloeotribus scarabaeoides (Bernard, 1790) ( Curculionidae , Scolytinae ).

Eurytoma aloisifilippoi (Russo) : Boucˇek, 1974: 267 comb. nov.

Type material

Lectotype ♀, here designated, glued on a rectangular card and labelled ‘Pisciotta 2-IX-937 ulivo’ (manuscript)/ ‘ Decatoma ♂ sp. ♀ tipo’ (manuscript, writing different)/ ‘ Decatoma Luigifillopoi n. sp. Russo’ [sic] (manuscript, still another writing) (in MES) . Paralectotypes, conspecific with the lectotype. One male, also glued on a rectangular card, is labelled ‘Pisciotta Sett. 934’ (manuscript)/‘ Decatoma Aloisifilippoi Russo’. Other paralectotypes came from Pisciotta, except one male from Portici. One female has the same references as the lectotype and one male was also collected at the same time; the other specimens (4 ♀, 5 ♂) were collected in 1934 (all specimens in MES) .

Diagnosis

Body with extensive light coloration, on following parts: lateral panel of pronotum anteriorly, pro- and mesocoxae, acropleuron, edge of oral fossa, and a subantennal stripe. Clypeus distinctly emarginate. Lower face densely and thickly setose. Funicular segments relatively short. Notauli well visible, impressed, not obliterated by the sculpture of the mesoscutum. Median channel of propodeum with complete median ridge. Lower surface of costal cell completely densely setose. Marginal vein quite thick, 2.90 times as long as wide, widening distad. Wing membrane with relatively broad diffuse infumation behind marginal vein. Petiole fairly long with mediodorsal ridge. Gaster relatively short. Male with extensive light colour, at least on the whole ventral side of the body. Scape with a small apicoventral swelling. Funicular segments F1–F3 slightly nodiform, with short apical peduncle, F4 and F5 symmetric.

Host: Phloeotribus scarabaeoides , a wood boring beetle infesting Olea europaea L., 1753 and Fraxinus excelsior L., 1753 ( Oleaceae ).

Distribution

This is a rather rare species, only known from the Mediterranean subregion. Apart from southern Italy it was collected in southern France near Montpellier. Its actual distribution is probably much wider, including at least part of the Mediterranean region (see Appendices S4 and S8).
