Diagnosis.
Hind tibia with an oblique carinula basally (
Figs 12
,

,

,
62
) or with series of fine oblique striae; frons with pair of distinct depressions above antennal sockets (
Figs 10
,

,

,
47
); occipital carina present laterally not or slightly curved ventrally and remaining removed from hypostomal carina, near level of middle of eye straight or nearly so, without transverse carina or crest; clypeus thin and protruding or truncate ventrally, more or less convex and of variable height; labrum normal, without emargination ventrally; hypoclypeal depression distinct; mandible triangular, gradually narrowed apically, slender basally (at most slightly widened) and twisted apically, with ventral carina; medio–posterior depression of mesoscutum usually present (
Figs 4
,

,

,
54
); pronope slit–like or elliptical, very large to large and deep, rarely absent; scutellar sulcus usually rather wide; posterior face of propodeum without distinct areolation (
Fig. 44
); epicnemial area more or less crenulate or smooth; precoxal sulcus usually distinctly sculptured; postpectal carina completely absent; vein m-cu of fore wing usually distinctly postfurcal (
Figs 2
,
15
,
28
,
41
), sometimes subinterstitial; vein 1-M of fore wing more or less curved and in part of species vein 1-SR comparatively long; vein 3-SR of fore wing distinctly longer than vein 2-SR; length of setose part of ovipositor sheath 0.1–0.8 × fore wing.
Biology.
Parasitoids of fruit infesting
Tephritidae
and to a lesser degree of
Agromyzidae
and
Anthomyiidae
; it should be noted that at least some of the records of the latter group may be the result of misidentification of the hosts (because of mass rearing) or of the parasitoids.
Distribution.
Cosmopolitan.
