Euodynerus dantici (Rossi)

( Figs. 18–27)

A nest (length = 110 mm; diameter = 4 mm) was obtained from a reed stem at Salduero ( Soria , Spain). The nest had a vestibular cell (l = 45 mm), initial and final plugs (l = 5 mm) and 7 cells (range = 9-20 mm, x (mean) = 13) separated by mud plugs. All cells included a cocoon. The mature larvae of cells 3–5 were preserved for study (reference = 1988EE3–5). Four females emerged (March 1999) from cells 2 and 6–8, and a male from cell 1 .

Body ( Fig. 18) (l = 13–13.5 mm, maximum w = 2.5 mm) fusiform, robust, with some segments divided into two annulets by transverse crease. Anus ( Fig. 19, a) terminal, as transverse slit, with dorsal lobe smaller that ventral one. Pleural lobes developed. Integument with scattered setae ( Fig. 19, b) (l = 25 µm). Spiracles ( Figs. 20, 21) (d = 120–150 µm) with walls of atrium with asperities ( Fig. 21, as); opening into subatrium spinulose; subatrium with 5 swellings.

Cranium ( Fig. 22) (w = 1.6 mm, h (exclusive of labrum) = 1.3 mm) with sparse setae (l = 20 µm) and sensilla. Coronal suture absent and parietal bands present ( Fig. 22, pb). Antennae ( Fig. 22, a) (d = 75 µm) circular, with 4 sensilla. Clypeus ( Fig. 23, c) with scattered setae (l = 20 µm) and punctures. Labrum ( Figs. 23, l; 24, a) (w = 660 µm) emarginate, with around 42 sensilla (w = 6–7 µm). Epipharynx ( Fig. 24, b) with 12 sensilla of which 4 (d = 3 x 5 µm) are marginal and protuberant and 8 (d = 5–6 µm) are situated in central-apical position, distributed in two areas with 4 sensilla on each.

Mouthparts. Mandible ( Fig. 23, m) (l = 600 µm, w = 300 µm) tridentate. Maxilla ( Figs. 23, ma; 25) (w = 350 µm) spinulose on lacinial area and with several setae (l = 5–25) µm) on external part. Maxillary palpus ( Fig. 26) (h = 80 µm, w = 70 µm) with 5 apical sensilla; galea ( Fig. 25) (h = 50 µm, w = 40 µm) with 2 apical sensilla. Labium ( Fig. 27) (w = 350 µm) setose and spinulose dorsally to salivary orifice ( Fig. 27, a); labial palpus ( Fig. 27, b) (l = 150 µm, w = 100 µm) with 5 apical sensilla; prementum with 8 setae ( Fig. 27, c) (l = 5 µm) around each palpus; salivary orifice as transverse slit (w = 260 µm).
