Dinotrema munki Peris-Felipo , sp. nov.

( Figs 54–67 )

Etymology. Named in honor Dr Thorkild Munk, Danish hymenopterist.

Type material. Holotype: female, Spain, Castellon Province, Pobla de Benifassà, Natural Park of Tinença de Benifassà, 15.010.2007 (F.J. Peris-Felipo leg.) (ENV). Paratype: 1 male, same label as in holotype, but 28.10.2004 (ENV).

Description. Female.

Head. In dorsal view, 1.90x as wide as median length, 1.45–1.50x as wide as mesoscutum, smooth, with rounded temples behind eyes. Eye in lateral view 1.80–1.85x as high as wide, 0.70–0.75x as wide as temple. POL 3.25–3.30x OD; OOL 3.30–3.35x OD. Face 0.65x as wide as high; inner margins of eyes subparallel. Clypeus 2.50x as wide as high, slightly curved ventrally. Paraclypeal fovea elongated, reaching middle distance between clypeus and eye. Mandible distinctly widened towards apex, 0.80–0.85x as long as its maximum width. Upper tooth large, weakly shorter than middle tooth. Middle tooth rather short, wide basally and pointed apically. Lower tooth rather long, rounded apically, not longer than upper tooth. Antennae thick, 17–segmented, shorter than body. Scape 1.90–1.95x as long as pedicel. First flagellar segment 2.35–2.40x as long as its apical width, 1.30–1.35x as long as second segment; second segment 1.60x as long as its maximum width. Third to fourteenth flagellar segments 2.00x and fifteenth segment 2.30x as long as their maximum width.

Mesosoma. In lateral view, 1.10–1.15x as long as high. Mesoscutum as long as maximum width, with two rows of single setae around trace of notauli. Notauli absent at most posterior part. Mesoscutal pit present, oval. Prescutellar depression smooth, with distinct median carina. Sternaulus (precoxal suture) present, short, far not reaching anterior and posterior parts of mesopleuron. Posterior mesopleural furrow entirely smooth. Propodeum mainly smooth, with median longitudinal carina crossing from anterior to posterior its margins, with transverse carinae emerging from median carina in its anterior half and not reaching propodeal edges. Propodeal spiracles relatively small.

Legs. Hind femur 3.90–4.00x as long as wide. Hind tibia weakly widened to apex, 9.90–10.00x as long as its maximum subapical width, 1.00–1.05x as long as hind tarsus. First segment of hind tarsus 1.60–1.65x as long as second segment.

Wings. Length of fore wing 2.30–2.40x its maximum width. Vein r1 present but hyaline. Radial cell reaching to apex of wing, 4.15–4.20x as long as its maximum width. Nervulus distinctly postfurcal. Brachial cell closed, short, widened apically, about 2.80x as long as its maximum width. Hind wing 5.40–5.50x as long as its maximum width.

Metasoma. Distinctly compressed laterally. First tergite weakly widened towards apex, 1.90x as long as its apical width, rather distinctly striate in apical half. Ovipositor 2.80–3.00x as long as first tergite, shorter than metasoma, 1.45–1.50x as long as hind femur.

Colour. Body and legs brown to dark brown. Wings hyaline. Pterostigma brown.

Length. Body 1.95–2.00 mm; fore wing 2.00 mm.

Male. Body length 1.90 mm; fore wing length 2.15 mm. Antenna 22-segmented. First flagellar segment 3.10x as long as its maximum width. Middle flagellar segments about 2.00x as long its maximum width. Hind femur 3.85x as long as wide. Otherwise similar to female.

Diagnosis. This new species resembles D. brevisulcus Tobias and D. puliciforme (Fischer) . Dinotrema munki sp. nov. differs from D. brevisulcus in having the mandible 0.80–0.85x as long as wide (1.10x in D. brevisulcus ), and ovipositor distinctly shorter than metasoma (longer than metasoma in D. brevisulcus ). On the other hand, D. munki differs from D. puliciforme in having the first flagellar segment 2.35–2.40x as long as its maximum width (4.00x in D. puliciforme ), and mandible 0.80–0.85x as long as wide (1.60x in D. puliciforme ).
