Aegilips armatus Giraud, 1860: 173 (female).

Xyalaspis armata – Kieffer 1901: 161.

TYPE MATERIAL. — Holotype. ♀ with the following labels: “ Holotype ” (red label); “Muséum Paris, coll. Giraud 1877” (white label); “ Holotype of Aegilips armatus Giraud , det. N. D. M. Ferguson, 1981” (white label); “ Xyalaspis armatus (Giraud) ♀, Kieffer, 1901, det. N. Mata-Casanova, 2012” (white label). ( Deposited in MNHN).

BIOLOGY. — Unknown.

DISTRIBUTION. — Palaearctic. Known from Sweden, Britain (Kieffer 1901); Germany, Austria (Dalla Torre & Kieffer 1910); Russia ( Belizin 1951); Ireland (Ferguson 1986); Spain (Ros-Farré & Pujade-Villar 1997).

DIAGNOSIS. — Species with completely smooth mesoscutum similar to X. atemiensis Ashmead, 1904 and X. pilosa Mata-Casanova, 2013 , from which it differs by the lack of internal carinae in the mesoscutum (notauli internally carinated in X. atemiensis and X. pilosa ).

Body 3.1 mm. Wings 3.1 mm. Antennae 2.8 mm.

Coloration

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

Width of head 2 × its height in front view and 1.3 × its length in dorsal view. Face smooth, shiny and pubescent, with abundant piliferous punctures. Malar sulcus present, coriaceous, 0.7 × height of compound eye. Transfacial line 1.2 × height of compound eye. Diameter of toruli larger than inter-toruli distance and that of torulus to compound eye. Clypeus short; smooth, glabrous and convex. Occipital and postocular carinae absent. Compound eyes almost glabrous except for a few short setae. POL:OOL:LOL ratio = 8:6:3, ocelli diameter 2. Frons smooth, shiny and shortly pubescent with some punctures.

Scutellum as long as mesoscutum in dorsal view. Scutellar foveae alutaceous, basally defined by a carina. Interfoveal line complete. Lateral pits of scutellar foveae weakly excavated. Scutellar spine with parallel sides and ending in a spike; nearly one-half of mesoscutellum length and slightly projecting upwards in lateral view. Mesopleuron smooth, shiny and glabrous, with weak basal transverse carinae. Mesopleural triangle smooth and pubescent. Propodeum heavily areolate; central area delimited by two longitudinal carinae and internally divided by some incomplete and weak internal carinae.
