Redescription

Colouration. Head and metasoma dark brown; mesosoma brown; scape yellowish brown; pedicel–F3 dark yellow, and F4–F12 brown; legs dark yellow.

Head. It cannot be seen.

Antenna. Female: 13-segmented, filiform; all antennomeres covered with sparse setae; F1–F3 thinner and smooth than remaining flagellomeres; F4–F11 with rhinaria and club shaped; antennal formula: 2.7 (1.8); 4.0 (1.1); 3.5 (1.1); 3.0 (1.1); 3.5 (1.6) (fig.2f). Male:14-segmented, filiform; allantennomeres covered with sparse setae; F1–F3 thinner and smooth than remaining flagellomeres; F4–F12 with rhinaria and club shaped; antennal formula: 2.5 (2.0); 3.6 (1.1); 3.0 (1.2); 3.0 (1.2); 3.0 (1.5) (fig. 2b).

Mesosoma. Pronotum covered by few setae, almost absent on distolateral corners and in central area; without carinae present (fig. 2c); mesoscutum smooth and shiny, round in dorsal view with few scattered setae; scutellum also smooth and shiny with scattered setae, which are more abundant on apex of scutellum; height of mesopleural triangle along anterior margin 1.4 times height of mesopleuron; propodeum covered with setae, without carinae (fig. 2d).

Forewing. Shorter than body length, 2.8 times as short as mesosoma and metasoma together in both male and female (fig. 2a and g); covered with dense pubescence; marginal setae present; without radial cell.

Metasoma. Anterior part with an incomplete ring of setae, glabrous at centre, wider laterally; metasoma smooth and shiny, T3 and T4 clearly visibly distinguished.

Distribution. Palaearctic.

Comments. According to Quinlan and Fergusson (1981), Alloxysta pedestris (Curtis) is represented by three specimens in the Curtis collection (two males and one female). One male was designated by Quinlan and Fergusson (1981) as the lectotype because it corresponds more precisely with the original description; the female is considered to be a paralectotype; the other male cannot be a syntype because of the date. As a result of this, the type series of Alloxysta pedestris consists of just two specimens, lectotype male and paralectotype female, here studied.
