Cecidostiba fungosa View in CoL (Geoffroy in Fourcroy, 1785)

Measurements. Body length: 1.8 mm, width: 0.62 mm (n=1) ex gall Andricus quercusradicis (Fabricius) (Sexual generation).

Description ( Figs 4 View FIGURE 4 B, 5B). Whitish; integument mostly smooth and glabrous on all body segments; small, 2.5× as long as broad and tapering gradually posteriorly ( Fig. 4 View FIGURE 4 B) and strongly curved ventrally in lateral view ( Fig. 5 View FIGURE 5 B); ventral margins of body segments straight.

Head (anterior view) more or less trapezoid, 1.1–1.3× as broad as high; vertex slightly incised medially ( Fig. 6 View FIGURE 6 B); cephalic chaetotaxy pattern as in A. glandium consisting of by very short and inconspicuous setae ( Fig. 6 View FIGURE 6 B); ventral margin of clypeus straight; labrum large and trapezoid, more than 4× wider than long ( Fig. 7 View FIGURE 7 B).

Mouth parts ( Fig. 7 View FIGURE 7 B). Maxillae indistinct; two pairs of inconspicuous maxillary setae; labium sub-rectangular, rugose and convex and not collapsed; labium setae invisible.

Mandibles ( Fig. 8 View FIGURE 8 B); tooth almost 1.8× longer than wide measured at its base; angle separating inner side of tooth and base of the mandible obtuse (>90º); outer margin of tooth almost straight, slightly curved near sharp apex.

Biology. Adults of C. fungosa ( Fig. 9 View FIGURE 9. A E) are common, widespread parasitoids in oak gall wasp communities ( Askew 1961; Schönrogge et al. 1996; Bailey et al. 2009; Lohse et al. 2010). In Europe it has been reared mainly from galls of Biorhiza pallida (Olivier) and several species of Andricus Hartig and Cynips Linnaeus (Cynipidae) ( Nieves-Aldrey & Askew 1988).

Material examined. ex gall A. quercusradicis (Sexual generation) on Quercus pyrenaica , Spain, Madrid: El Escorial (29/VI/2006) J. L. Nieves leg. (n=3).
