BIOLOGY. — Unknown.

DISTRIBUTION. — Palaearctic. Known from Austria ( Hartig 1843); first records for Spain, Andorra, France, Romania, Norway and Iran.

DIAGNOSIS. — Species having a weak carinated sculpture at the base of notauli like Xyalaspis hyalina ; it can be distinguished by the presence of complete notauli and having antennae shorter than the body (complete notauli and antennae longer than the body in X. hyalina ).

REDESCRIPTION

Length

Body: 2.9 mm. Wings: 2.7 mm. Antennae: 2.8 mm (♂), 2.6 mm (♀).

Coloration

Head, mesosoma and metasoma black. Mandibles yellowishbrown with darker teeth. Antennae yellowish-brown. Legs yellowish-brown with darker coxae. Wing venation yellow.

Head

Width of head 1.3 × height in front view and 2 its length in dorsal view.Face smooth, shiny and pubescent, with abundant piliferous punctures. Malar sulcus present, coriaceous, 0.6 × height of compound eye. Transfacial line 1.2 × height of the compound eye. Diameter of toruli larger than inter-toruli distance and torulus to compound eye distance. Clypeus not apparent; smooth, glabrous and convex. Occipital and postocular carinae absents. Compound eyes almost glabrous except for several short setae concentrated in central eye. In females, POL: OOL: LOL ratio = 7:6:2.5, ocelli diameter 2; in males, POL: OOL: LOL ratio = 7:4:3, ocelli diameter 3.5. Frons smooth, shiny and shortly pubescent with some punctures.

Antennae

Flagellomeres cylindrical and hairy. Male antennal formula (type material only has from scape to F 4, but other specimens with complete antennae have been used to complete the antennal formula): 10(3.5), 4(3.5), 10(3), 10(3), 10(3), 9(3), 9(3), 9(3), 8(3), 8(3), 7(3), 7(3), 6(3), 9(3). Female antennal formula: 11(3.5), 4(3), 10(2.5), 11(3), 9.5(3), 9.5(3), 8(3), 7.5(3), 7(3), 5(3), 5(3), 5(3), 9(3). Placodeal sensilla start at F 2 in females and at F 1 in males.

Mesosoma

Pronotum carinated in its lower part and on its margins but alutaceous in its upper part ( Fig. 2B ). Mesoscutum 1.2 wider than long in dorsal view. Mesoscutum smooth, pubescent and punctate, with alutaceous sculpture at base of notauli ( Figs 1C ; 3C ), mesoscutum almost entirely carinated in some specimens ( Fig. 3D ). Notauli complete but weakly impressed, fading at anterior mesoscutum, not internally carinated; median mesoscutal furrow weakly impressed. Parapsidal signum and parascutal sulcus absent. Scutellum length subequal to mesoscutum length (22:23) in dorsal view. Scutellar foveae smooth, basally defined by a carina, an oblique internal carina present in some specimens. Interfoveal line complete. Lateral pits of scutellar foveae weakly impressed. Scutellum narrowing at base of scutellar spine; scutellar spine with parallel sides, projected from scutellum and straight in lateral view; between one-quarter to one-third of entire scutellum length. Mesopleuron smooth, shiny and glabrous, with basal trans- verse carinae. Mesopleural triangle smooth and pubescent. Propodeum heavily areolate and pubescent; central area divided by a longitudinal median carina and a transverse carina which define two small, lower cells and two larger upper cells crossed by weaker transverse ridges.

Wings

Radial cell of forewing closed, 2.7 longer than wide. Marginal pubescence of forewing denser in its apical third.

Metasoma

Petiole longer than wide, ventrally and laterally carinated and dorsally smooth. T 3 2.5 × longer than T 4 in dorsal view. T 5 and T 6 visible in dorsal view. Anterior margin of T 4- T 7 punctate.

REMARKS

Although Hartig’s (1843) original description mentions the holotype as being a female, it has 14 antennal segments and the metasomal shape of a male, so we concluded that Hartig was in error and the holotype of X. laevigata is a male.
