Pseudidarnes Girault, 1927

Type species.

Pseudidarnes minerva Girault, 1927, by monotypy.

Diagnosis.

Female. Body length (excluding ovipositor) 2.3-3.7 mm. Body colour variable, yellow to dark brown, sometimes with green metallic tinge.

Head. Face sculpture smooth to reticulate or slightly engraved, sometimes punctate. Antennae inserted well above to slightly below the middle line of compound eyes, but never very close to the clypeal margin. Toruli separated by one torulus diameter or less. Clypeal margin bilobed. Maxillary palpi composed of four segments. Labial palpi composed of three segments. Supraclypeal area delimited by subantennal grooves. Antenna with 13 segments (two anelli), and a 14th segment very short and unconspicuous. Funicular segments 1-2 × as long as wide.

Mesosoma. Pronotum 1-2 × as long as high in lateral view. Notauli complete, deep and at least slightly crenulated. Mesoscutum as long as wide or longer than wide. Axilullar sulcus straight to slightly concave. Propodeum transverse, smooth to slightly reticulate and sometimes with a median sulcus. Wings hyaline, sometimes slightly infuscate medially. Marginal vein as long as stigmal vein, or longer. Postmarginal vein present (very short in Pseudidarnes cooki sp. n.). Marginal and postmarginal vein sometimes particularly widened (as Figs 4D, 6D, 8D, 10D & 16D).

Metasoma. First metasomal segment petiolate (petiole short in Pseudidarnes acaudus sp. n.). Ovipositor sheaths as long as body or shorter (very short in Pseudidarnes acaudus sp. n.).

Male. Very similar to female, usually slender and sometimes showing tinge variation. Male with very different colour patterns in Pseudidarnes astridae sp. n. (Figs 3-6).
