Dinotrema fischerianum Peris-Felipo , sp. nov.

( Figs 42–53 )

Etymology. Named in honor Dr Maximillian Fischer, well-known Austrian hymenopterist for his great contribution into the study of the World Alysiinae .

Type material. Holotype: female, Spain, Alicante Province, Alcoi, Natural Park of Carrascal de la Font Roja, 25.04.2007 (F.J. Peris-Felipo leg.) (ENV). Paratype: 1 female, same label as in holotype, but 13.05.2004 (ZISP); 1 female, Spain, Castellon Province, Pobla de Benifassà, Natural Park of Tinença de Benifassà, 23.04.2007 (F.J. Peris-Felipo leg.) (ENV).

Description. Female.

Head. In dorsal view, 1.80x as wide as median length, 1.35–1.40x as wide as mesoscutum, smooth, with rounded temples behind eyes. Eye in lateral view 1.40x as high as wide and 1.05–1.10x as wide as temple. POL about 3.60–3.70x OD; OOL 3.50–3.55x OD. Face 0.50x as wide as high; inner margins of eyes subparallel. Clypeus 3.50x as wide as high, slightly curved ventrally. Paraclypeal fovea rounded, not reaching the middle distance between clypeus and eye. Mandible widened towards apex, 1.55-1.60x as long as its maximum width. Upper tooth small, distinctly shorter than middle tooth. Middle tooth the longest, wide basally and pointed apically. Lower tooth rounded, weakly longer than upper tooth. Antennae thick, 16-segmented, shorter than body. Scape 2.40–2.45x as long as pedicel. First flagellar segment 2.70–2.80x as long as its apical width, 1.35–1.40x as long as second segment; second segment 1.60–1.65x as long as its maximum width. Third flagellar segments 1.50x. Fourth to eleventh segment 1.20–1.30x, twelfth and thirteenth segments 1.05–1.10x, and fourteenth segment 1.75–1.80x as long as their maximum width.

Mesosoma. In lateral view, 1.20x as long as high. Mesoscutum as long as maximum width with 2 rows of couple setae around notauli. Notauli absent at most posterior part. Mesoscutal pit present, but slender and elongated. Prescutellar depression smooth, with double median carina. Sternaulus (precoxal suture) present, distinct, reached anterior and posterior parts of mesopleuron. Posterior mesopleural furrow crenulate in lower half. Propodeum mainly smooth, with median longitudinal carina crossing from anterior to posterior its margins, with short carinae emerging from median carina and not reaching propodeal edges. Propodeal spiracles relatively small.

Legs. Hind femur 4.00x as long as wide. Hind tibia weakly widened to apex, 7.05–7.15x as long as its maximum subapical width, 1.00–1.05x as long as hind tarsus. First segment of hind tarsus 3.25–3.30x as long as second segment.

Wings. Length of fore wing 2.5–2.6x its maximum width. Vein r1 present. Radial cell reaching to apex of wing, 3.70x as long as its maximum width. Nervulus distinctly postfurcal. Brachial cell closed, short, distinctly widened apically, 2.50–2.60x as long as its maximum width. Hind wing 5.90–6.00x as long as its maximum width.

Metasoma. Distinctly compressed laterally. First tergite weakly widened towards apex, 1.70–1.75x as long as its apical width, smooth medioposteriorly, finely rugulose basally and laterally. Ovipositor 1.80–1.90x as long as first tergite, shorter than metasoma, almost as long as hind femur.

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

Length. Body 1.90–2.00 mm; fore wing 2.15–2.20 mm.

Male. Unknown.

Diagnosis. This new species resembles D. caesum Tobias, D. subtauricum Tobias, D. sauricum Tobias and D. incongruens (Fischer) . Dinotrema fischerianum sp. nov. differs from D. caesum , D. subtauricum and D. sauricum in having the ovipositor shorter than metasoma (longer than metasoma in other three species), mandible 1.70x as long as wide (1.30–1.50x in other three species), and sternaulus reaching with anterior and posterior parts of mesopleuron (not reaching in other three species). New species differs from D. incongruens in having the ovipositor shorter than metasoma (longer than metasoma in D. incogruens ), mandible 1.70x as long as wide (1.35x in D. incogruens ), middle tooth more pointed and low tooth more rounded (different condition in D. incongruens ), and sternaulus reaching with anterior and posterior parts of mesopleuron (not reaching posterior part of mesopleuron in D. incongruens ).
