Apanteles philoeampus Cameron, 1911: 342 (lectotype, ♀, NHMUK).

Diagnosis

Cotesia philoeampa can be separated from all other species of Cotesia currently described from Australia and Papua New Guinea primarily by the fore wing vein 2RS extending past junction with r, creating a ‘stub’; T1 parallel sided; anteromesoscutum punctate; fore wing vein r generally shorter than 2RS (occasionally of similar length).

Redescription

Female (from lectotype)

COLOUR. Head, antenna and mesosoma dark, T1–2 dark, rest of metasoma pale on non-sclerotised areas with dark sclerotised areas on dorsal surface, pale laterally; (fore-, mid-, hind coxa) dark, dark, dark; femora (fore-, mid-, hind femur) pale, pale, pale darkening distally; tibiae (fore-, mid-, hind tibia) pale, pale, pale darkening distally; tegula and humeral complex pale to light brown; pterostigma light brown; fore wing veins light brown.

BODY LENGTH. Head to apex of metasoma: 2.9 mm.

HEAD. Antenna broken in types; OOL/posterior ocellus diameter 1.6; POL/posterior ocellus diameter 1.6; antennal flagellomere 2 length/width 3.1; antennal flagellomere 14 missing in type specimens.

MESOSOMA. Anteromesoscutum punctate, punctures denser and tending towards rugose along notauli lines compared to lateral areas and centre area, where punctures are shallower and ateromesoscutum appears smoother; number of pits in scutoscutellar sulcus 9; scutellar disc mostly smooth with some shallow punctures associated with setae; maximum height of mesoscutellum lunules/maximum height of lateral face of mesoscutellum 0.5.

WINGS. Fore wing length 3.0 mm; length of veins r/2RS 0.7–0.9; length of veins 2RS/2M 1.8; length of veins 2M/(RS+M)b 0.9; pterostigma length/width 3.2.

LEGS. Hind tibia inner spur length/metabasitarsus length 0.6.

PROPODEUM. Medial carina present, but carina not more prominent than other carinae on propodeum, all of propodeum irregularly rugose.

METASOMA.T1 length /T1 width at posterior margin 1.3; mostly parallel-sided, curving in right at posterior edge and bulging outwards a small amount in the posterior third, smooth in anterior half, posterior half with rugose and reticulate rugose sculpturing; T2 width at posterior margin/ T2 length 2.3, wide and flat, covering most of metasoma width, slightly curved from anterior corners, very shallow indistinct sculpturing around edges – rugulose at anterior end, crenulate at posterior margin; T2 length / T3 length 0.7; T3 sculpture smooth and shiny; ovipositor sheaths length/hind tibial length 0.16.
