Diagnosis

Female

All funiculars wider than long, Fu3 only slightly smaller than Fu2 and Fu4 ( Fig. 7E ); ventral margin of clypeus weakly convex ( Fig. 7D ); head in frontal view with gena buccate ( Fig. 7C ); hind tibia length about 8× width; gaster longer than combined length of head and mesosoma and strongly compressed laterally ( Fig. 7A ); tip of hypopygium not incised ( Fig. 7I ); ovipositor sheath length about 1.2 × length of hind tibia.

Male

Fore and mid tibiae normal, hind tibia inflated, length about 3.5× width ( Fig. 7B ). All funicular segments wider than long ( Fig. 7F ). Fore wing with upper side of basal cell with one irregular row of setae plus several additional ones near basal vein.

Etymology

The species name refers to the long ovipositor that characterizes the females of this species (from the Latin words ‘ longus ’ = ‘long’ and ‘ cauda ’ = ‘tail’; noun in apposition).

Description

Female holotype

Body length: 1.3 mm. Colour as in Fig. 7 . Head in frontal view with vertex not protruding between posterior ocelli ( Fig. 7C ). Gena buccate ( Fig. 7C ). Ventral margin of clypeus weakly convex ( Fig. 7D ). Upper face uniformly and very superficially sculptured except several piliferous punctures ( Fig. 7C ). Length of pedicel plus flagellum slightly longer than head width. All funiculars wider than long, Fu3 only slightly smaller than Fu2 and Fu4 ( Fig. 7E ). Mesosoma dorsally almost flat ( Fig. 7A ). Pronotum shorter than mesoscutum ( Fig. 7H ). Basal cell of fore wing with a few scattered setae on upper side ( Fig. 7G ). MV about 2.9 × SV. Hind tibia length about 8 × width. Gaster longer than combined length of head and mesosoma and strongly compressed laterally ( Fig. 7A ). Tip of hypopygium not incised (cf. Fig. 7I ). Ovipositor sheath length about 1.2× length of hind tibia.

Male allotype

Body length: 1.0 mm. Differs from the female holotype mainly in the structure of the antenna (see generic diagnosis) and the characters given in the above species diagnosis; mesosoma less flattened and gaster much shorter ( Fig. 7B ).

Variation

Female

Body length: 1.3–1.5 mm. MV 2.9–3.2 × SV.

Distribution

Zimbabwe.

Hosts

Unknown.

Taxonomic comments

Ecrizotes longicauda sp. nov. is the species whose females have the longest ovipositor ( Fig. 7A ). Both sexes are superficially similar to E. longus sp. nov. The two sexes were associated based mainly on the setation of the basal cell. The female of E. longicauda differs from the female of E. longus in having a much longer ovipositor and a non-anelliform Fu3 ( Fig. 7E ), while the male of E. longicauda differs from the male of E. longus in having the hind tibiae less strongly inflated ( Fig. 7B ).
