Fig. 2

Diagnosis

Female

All funiculars wider than long, Fu3 anelliform (Fig. 2E); ventral margin of clypeus strongly convex (Fig. 2D); head in frontal view with gena buccate (Fig. 2C); hind tibia length almost 7× width; gaster shorter than combined length of head and mesosoma, moderately compressed laterally (Fig. 2A); tip of hypopygium not incised (cf. Fig. 7I); ovipositor sheath length about 0.01 × length of hind tibia.

Male

Hind tibia slightly widened, length 4.4–4.7 × width (Fig. 2B). Funicular segments wider than long (Fig. 2F). Fore wing with upper side of basal cell having one irregular row of setae plus several additional ones near basal vein.

Etymology

The species name refers to the very short ovipositor that characterizes the females of this species (from the Latin words ‛ brevis ’ = ‛short’ and ‛ cauda ’ = ‛tail’; noun in apposition).

Description

Female holotype

Body length: 0.75 mm. Colour as in Fig. 2. Head in frontal view with vertex protruding between posterior ocelli (Fig. 2C). Gena buccate (Fig. 2C). Ventral margin of clypeus strongly convex (Fig. 2C). Upper face smooth except rare piliferous punctures (Fig. 2C). Length of pedicel plus flagellum shorter than head width. All funicular segments wider than long, Fu3 anelliform, barely visible (Fig. 2E). Mesosoma dorsally almost flat (Fig. 2A). Pronotum about as long as mesoscutum (Fig. 2G). Basal cell of fore wing with a few scattered setae on upper side (Fig. 2H). MV about 3 × SV. Hind tibia length about 6.6 × width. Gaster shorter than combined length of head and mesosoma, moderately compressed laterally (Fig. 2A). Tip of hypopygium not incised (cf. Fig. 6I). Ovipositor sheath length about 0.01 × length of hind tibia.

Male allotype

Body length: 0.9 mm. Differs from the female holotype in the structure of the antenna (see generic diagnosis) and in the characters stated in the above species diagnosis. Additionally, the mesosoma is more convex and the pronotum is shorter than the mesoscutum (Fig. 2B).

Variation

Male

Hind tibia length 4.4–4.7 × width.

Distribution

South Africa.

Hosts

Unknown.

Taxonomic comments

This species is somewhat similar to E. monticola, from which it differs mainly in the characters given in the key.
