description
Description. Wing length: 4.5 mm. Head: face longer than broad, face and clypeus rather coarsely granulate, making punctures almost invisible; clypeus relatively narrow and strongly convex, with narrow and smooth apical margin; malar space shorter than basal width of mandibles; mandibles strongly narrowed towards apex; frons sculptured much as face, but vertex and temples much more finely granulate; occiput descending immediately behind ocelli, and temples very strongly narrowed behind eyes; antenna somewhat broadened in distal half, but distally tapering: 32 flagellomeres. Mesosoma: pronotum without epomia; mesoscutum finely and evenly granulate throughout, position of notauli marked only by bands of slightly outstanding short ridges; mesopleuron, including speculum, finely granulate virtually throughout without visible punctures, apart from some short longitudinal striae in front of mesopleural fovea and a few longer striae beneath tegular ridge; metapleuron slightly more coarsely rugose, especially in a band along dorsal edge; scutellum finely granulate, keeled only at extreme base; propodeum without clear keels, edges of area superomedia and area petiolaris outlined by irregular lines of rugosity; first lateral areas and front part of area superomedia finely granulate, rest of propodeum strongly transversely rugose; costulae absent, but their position indicated by abrupt change in surface sculpture. Wings narrow; fore wing 1 cu-a postfurcal; areolet sessile; nervellus vertical, slightly curved but not intercepted. Metasoma: first metasomal tergite with almost parallel sides to petiole, widening distally to a rectangular postpetiole, all very finely granulate almost to base of petiole; glymma large and obvious; 2 nd tergite 1.2 x as long as wide, thyridia small and close to base; surface of 2 nd tergite onwards smooth but not polished, apart from a slight rugosity in basal half of 2 nd tergite; 6 th and 7 th tergites entire; ovipositor shorter than apical depth of metasoma, very slightly upcurved, with a strong subapical notch. Colour: black; mandibles, underside of scape, fore and mid coxae, trochanters and trochantelli yellow, sometimes shaded with orange brown on mid coxa; first tergite black with reddish tinge at apex of postpetiole, 2 nd tergite orange, darkened at least in basal half, often up to five-sixths, with a narrow black line on apex of tergite; tergites 3 – 5 orange, 6 – 7 dark brown to black; all femora, tibiae and tarsi orange, hind tibia usually only faintly darkened at extreme base and apex, sometimes more extensively at apex; visible sternites orange. Male (based on a single specimen): very similar to female, but with fore and mid legs paler, almost clear yellow, and more extensive darkening on the hind part of the metasoma.
diagnosis
Diagnosis. Most similar to pale specimens of H. caedator, but easily distinguished by the sculpture of the propodeum, which is granulate throughout, with a broad, ill-defined area superomedia, and by the yellow underside to the scape. The reduced sculpture of the propodeum also distinguishes this species from H. alpicola.
