General features.

Head. Rounded in anterior view, eyes located at middle line of head, malar space subequal to the distance from external margin of the lateral ocellus to the dorsal margin of the compound eye, measured in anterior view of the head. Surface completely smooth, without any strigose, malar impression, epistomal sulcus or clypeo-pleurostomal lines. Clypeus almost straight, slightly projecting over mandibles, without marginal inflection. Setae sparse, concentrated principally below the toruli (Fig. 24[3]).

Antennae. Size of pedicel and flagellomeres vary among species. Female: 13-segmented, slightly clavate; two last segments (F10-F11) broadly jointed. Male: 14-segmented, slightly clavate or filiform; two last segments (F11-F12) broadly jointed.

Mesosoma. Pronotum have setae only in the anterior part; pronotal carinae is long, clearly indicated, and extends from scutum to the anterior part of pronotum (Fig. 24[4]). Mesoscutum smooth, shiny, and almost without setae. Mesopleuron smooth, without any longitudinal ridge in lower part (Fig. 24[2]). Scutellum smooth, with scarce setae at posterior and lateral parts. Propodeum with two strong, broad carinae. Apex of scutellum: Holarctic spp. ∩-shaped carina (Fig. 24[5]). Afrotropical spp. with one carina on each side, both symmetrical and parallel, with a distance between them equivalent to the distance between the propodeal carinae (Fig. 24[6]).

Forewing. Large, longer than body, covered with dense pubescence; marginal, long setae present; brown veins; radial cell small and completely open along anterior margin; R1 very short and barely reaches costal margin (Fig. 24[1]).

Distribution.

Holarctic, Afrotropical and Oriental regions ( Paretas-Martínez et al. 2011).

Hosts.

Endoparasitoids of Encyrtidae ( Hymenoptera : Chalcidoidea) that are endoparasitoids of psyllids ( Hemiptera : Psyllidae ) ( Fergusson 1986; Menke and Evenhuis 1991). Until now it has been cited in: Cacopsylla alba , Cacopsylla pyricola , Psylla pyri , Psyllopsis fraxini by Menke and Evenhuis (1991: 152); Trioza erytreae by Paretas-Martínez et al. (2009: 211) and Psyllidae on Firmiana simplex by Paretas-Martínez et al. (2011: 34).
