Name
Dinotrema robertoi Peris-Felipo sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
Holotype: 1 female (ENV), “Spain, Castellon Province, Pobla de Benifassà, Natural Park of Tinença de Benifassà, 22.vii.2004, F.J. Peris-Felipo”. Paratypes: 1 female (ENV), same label as holotype but 05.viii.2004; 1 female (ENV), same label as holotype but 16.ix.2004.
Diagnosis
This new species resembles Dinotrema compressum (Haliday) (comb. n.), but differs in having hind femur 3.5 times as long as its maximum width (4.0 times in Dinotrema compressum), first metasomal tergite 2.5 times as long as its apical width and smooth in apical half (2.3 times and striate in apical half in Dinotrema compressum), prescutellar depression rectangular and with lateral carinae (subsquare and without lateral carinae in Dinotrema compressum), and middle tooth short and apically rounded (large and pointed in Dinotrema compressum).
Description
Holotype, female. length of body 1.0 mm; fore wing 1.1 mm.
Head. In dorsal view, 1.5 times as wide as median length, 1.5 times as wide as mesoscutum, smooth, with rounded temples behind eye. Eye in lateral view 1.3 times as high as wide and 0.8 times as wide as temple. POL 3.6 times OD; OOL 4.7 times OD. Face 1.2 times as wide as high; inner margins of eyes subparallel. Clypeus 3.7 times as wide as high, slightly curved ventrally. Paraclypeal fovea short, not reaching the middle distance between clypeus and eye. Mandible widened towards apex, 0.95 times as long as its maximum width. Upper tooth of mandible larger than middle tooth and distinctly wider than lower tooth; middle tooth short, wide basally, distinctly narrowed towards apex, weakly rounded apically; lower tooth rounded apically. Antennae thick, 12-segmented. Scape 1.6 times as long as pedicel. First flagellar segment 2.6 times as long as its apical width, as long as second segment; second segment 2.1 times as long as its maximum width. Third to ninth flagellar segments 1.6 times as long as their width, tenth flagellar segment twice as long as its width.
Mesosoma. In lateral view, 1.3 times as long as high. Mesoscutum as long as maximum width. Notauli largely absent. Mesoscutal pit absent. Prescutellar depression smooth, without lateral carinae. Precoxal sulcus present, not reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow slightly crenulate below. Propodeum sculptured, with short median longitudinal carina, with emerging lateral carinae reaching propodeal edges. Propodeal spiracles relatively small.
Legs. Hind femur 3.5 times as long as wide. Hind tibia weakly widened to apex, about 7.9 times as long as its maximum sub-apical width, 0.9 times as long as hind tarsus. First segment of hind tarsus 1.7 times as long as second segment.
Wings. Length of fore wing 2.6 times its maximum width. Vein r1 present. Radial cell reaching to apex of wing, 4.0 times as long as its maximum width. Nervulus weakly postfurcal. Brachial cell closed, short, widened apically, 1.5 times as long as its maximum width. Hind wing 7.2 times as long as its maximum width.
Metasoma. Distinctly compressed. First tergite weakly widened towards apex, 2.5 times as long as its apical width, smooth. Ovipositor 0.7 times as long as first tergite, distinctly shorter than metasoma, 0.4 times as long as hind femur.
Colour. Body and legs dark brown. Wings hyaline. Pterostigma brown.
Male. Unknown.
Etymology
