Dinotrema mediocornis hispanicum nov.ssp. ( Figs 3, 4 )

D i a g n o s i s:Length: 2.3mm.Thespecimensofthisnewsubspeciesareexactlylike D. mediocornis mediocornis (FISCHER 1973) , from which it is distinguished by the following character states: a) T1 (petiole) is red instead of dark, and b) female antennae with 18-19 antennomeres. The male is new (is described for the first time), very similar to female, but antennae with 23 antennomeres.

Type material: Spain: Burgos: Sotopalacios, 20.VIII.1979, 1 (Holotype), 22.VIII.1979, 6, 23 (Paratypes).

E t y m o l o g y: The name of this subspecies refers to Spain, the country of which it is described for first time.

Body length: 2.3 mm.

.- Head: 1.8 times as wide as long, 1.3 times as wide as mesoscutum, between temples practically as wide as between eyes; eyes not protuberant, as long as temples; distance between toruli and distance of them from eyes as great as their diameter; occiput excavated, upper surface bare, only a few fine setae on its sides; ocelli slightly protuberant, distance between them twice as long as diameter of an ocellus, the distance between lateral ocellus and internal edge of eye as large as width of ocellar field. Head 1.6 times as wide as face. Head 1.4 times as wide as high, swollen, only flat on sides and without setae, with clear dense setosity directed upwards, setose punctation not recognizable, with some longer setae close to eyes, edges of eyes slightly curved and parallel. Clypeus twice as wide as high, trapezoidal, slightly swollen, with fine setae, separated from face by a smooth groove. Paraclypeal pits inclined, oval, their distance to eyes as great as their diameter. Head, in lateral view, as long as high; eyes, in lateral view, 1.7 as high as long, temples very slightly broader than length of eyes. Mandible 1.4 times as long as wide apically, widened distally, upper edge curved upwards, lower edge directed slightly downwards and hence widened in distal portion; tooth 1 rounded at apex, tooth 2 sharp, an acute notch between tooth 1 and tooth 2, tooth 3 rounded throughout width, a right angle between tooth 2 and tooth 3, outer edge of tooth 3 equipped with setae; external surface of tooth 3 with setae; outer surface completely bare; maxillary palpi as long as height of head. Antennae filiform, not as long as body, 23-segmented; F1 4 times longer than broad, only slightly narrower than others, Fm and Fp 1.8 times longer than wide; flagellomeres clearly separated from one another, setae longer than or as long as width of antennomeres of flagellum, three sensillae visible in lateral view.

Mesosoma: One third longer than high, 1.7 times higher than head, upper part swollen. Mesonotum 1.3 times wider than high, uniformly rounded in front of the tegulae, devoid of setae, with fine setae only on anterior declivity; notauli only developed at start, its assumed trajectory being insinuated by lines of fine setae; mid pit lengthened linearly, sides bordered all over, marginal sulci inconspicuous, reaching notauli. Prescutellar sulcus smooth, divided, each lateral field as long as wide. Scutellum, postaxillae and lateral areas of metanotum smooth. Propodeum with longitudinal carina and costulae complete, wrinkled around carinae, the point at which the carinae cross extended forming a small point; spiracles inconspicuous. Anterior furrow of the side of prothorax slightly crenellate. Sternaulus crenellate, shortened on both sides. Anterior mesosternal furrow and epicoxal furrow crenellate only on basal-most part; marginal posterior furrow punctate on basal zone, above almost smooth. Posterior femur 4.4 times longer than wide. Posterior tarsus as long as posterior tibia.

Fore wing: r emerges from behind the base of the st at a distance slightly shorter than the length of rl; r1 twice as long as width of st; r2 2.6 times longer than ccl; r3 curved outwards, 1.8 times longer than r2; R reaches tip of wing; nr. weakly postfurcal; cu2 only slightly narrowed distally; d twice as long as nr.; nv weakly postfurcal; B twice as long as wide, broadened distally; np emerges from below the middle of the distal side of B.

Metasoma: As long as head and mesosoma together. T 1 2.3 times longer than wide on posterior part, uniformly narrowed forwards, striated longitudinally, basal notch as wide as long, basal carinae converging backwards on anterior third, dorsal fossae deep. Distal tergites folded above. Ovipositor sheaths 1.7 times longer than T 1, the part surpassing the apex of the last segment of the metasoma as long as T 1.

Colouration: Black. Yellow: mouthparts, legs, tegulae and wing venation. Scape and pedicel brown. T 1 red. Ventral zone of metasoma partly brown, wing membrane hyaline.

.- Like male except antennae 18-19-segmented.
