description: Xyalaspis armata (Giraud, 1860)   
(Figs 1A; 2A; 4A)  
 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).   
REDESCRIPTION (FEMALE ONLY)  
 Length   
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.  
 Antennae   
Flagellomeres cylindrical and hairy. Antennal formula: 12(5), 4.5(4), 11.5(3), 12(3), 10.5(3.5), 10(3.5), 9.5(4), 9(4), 8(4), 6(4), 6(4), 6(4), 12(4). Placodeal sensilla start at F2.  
 Mesosoma   
Pronotum carinated in its lower part and smooth in the upper part (Fig. 2A). Mesoscutum 1.2 × wider than long in dorsal view. Mesoscutum smooth and shiny, almost glabrous except for few scarce setae and punctures. Notauli complete but weak, without internal transverse ridges (Fig. 1A); median mesoscutal furrow short and weakly impressed. Parapsidal signum and parascutal sulcus absent. 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.  
 Wings   
Pubescent. Radial cell of forewing closed, 2.2 × longer than wide. Marginal pubescence of forewing denser in apical third.  
 Metasoma   
Petiole wider than long, carinated on all sides (Fig. 4A). Third abdominal tergum 2.2 × longer than fourth abdominal tergum in dorsal view.T5 and T6 visible in dorsal view. Anterior margin of T4-T7 punctuate.
