Type material

Holotype ♀. France: Indre-et-Loire, Saché, Pré du Moulin Rouge , 48 m a.s.l., 47°15′05″N, 00°32′33″E, reared together with Rhabdophaga triandraperda Barnes, 1935 forming galls under the bark of Salix triandra ,, adult emergence on 14–16.vii.2012 (C. Kruczkowski) (in MHNG) GoogleMaps . Paratypes. Same data (4 ♀, 4 ♂) (two specimens sequenced with references EUR133, EUR134) (in MNHN, GDPC).


Small species (2.90 mm) with elongate gaster. Procoxa and ovipositor reddish. Legs mostly reddish, except metacoxa and small fuscous spots on meso- and metafemora. Head with thick and dense silvery setation. Lower face mostly punctured, with short radiating crests. Vertex punctured. Pro- and mesonotum densely punctured. Metacoxa bare dorsally at base. Setation of lower surface of costal cell as usual, not especially dense. Marginal vein not widened, long.


Female, body length 2.90 mm. Body, tegula, and teeth of mandibles black. Legs reddish, except metacoxa and black spot on metafemur. Scape reddish, pedicel and flagellum dark brown, almost black. Veins light brown. Setation on wings dark.

Head 1.82 times as wide as long and 1.25 times as wide as high, subtrapezoidal in frontal view. Outline of frons fairly convex. Temples short, progressively merging to occiput. Genae with smooth stripe behind malar sulcus, their outline evidently convex in frontal view. Clypeus somewhat protruding ventrally and slightly emarginate mesally on lower margin. OOL 0.80 times as long as lateral ocellus diameter. POL 2.0 times as long as median ocellus diameter. Malar space 0.76 times as long as width of oral fossa and 0.73 times height of eyes. Eyes separated by 1.40 times their height. Antennal scrobes much shorter than distance between antennal toruli and lower edge of clypeus.

Antenna. Funicular segments all much longer than wide, fusiform, bearing appressed setae and few MPS. Clava with constriction between the first segment and the following, broadly rounded at apex.

Mesosoma 1.83 times as long as wide. Setation thick and fairly long, suberect. Setae obliquely reclinate, directed to median line of mesosoma. Puncturation dense, the points subcircular, coriaceous sculpture of interspaces visible laterally. Pronotum 1.25 times as

long as mesoscutum. Collar on shoulders 1.32 times as long as lateral lobes. Notauli broadly impressed but obliterated by the sculpture of the mesoscutum. Scutellum about as long as wide. Propodeum with large, areolate, not well-delimited median channel. Lateral prepectus delimited ventrally by a distinct ridge. Anterior outline of mesepisternum hardly convex.

Appendices. Costal cell about as long as width of forewing. Marginal vein 7.20 times as long as wide, 1.78 times as long as the marginal vein, and 1.43 times as long as the postmarginal.

Metasoma. Petiole short with conical anteromedian tooth. Gaster 1.20 times as long as mesosoma, 2.17 times as long as height of third gastral tergite. GT4 quite long, conversely to the following tergites that are all very short ( Fig. 25K View Figure 25 ).

Male, body length 2.40 mm. Scape with moderately protruding ventral swelling at mid length, two-fifths as long as itself. Pedicel short. Funicular segments long and slender. F1–F4 slightly nodiform and with long apical peduncles. F5 symmetric and without peduncle.


The species name refers to the associate plant, a willow.


The species is similar to E. nobbei , and the two species were both reared on hosts infesting willows. Eurytoma saliphila sp. nov. has the head more transverse in dorsal

view with the vertex punctured. Its setation is more prominent, thick, and dense on the head.


The type series was reared together with the gall midge Rhabdophaga triandraperda (Cecidomyiidae) , the larvae of which make galleries at the crown and within the roots of the plant. Although such hosts seem quite different from the beetles usually parasitized by other species of the morio group, the habitat is much the same.


Eurytoma saliphila sp. nov. is only known from its type locality, in the centre of France (see Fig. S 10 View Figure 10 in Appendix S8) .
