Apechoneura nigricornis Mocsáry, 1905 (Description from Gauld, 2000) ( Figs 1-17 & 88 )

Diagnosis

Mesosoma and metasoma dull orange; areolet petiolate; ovipositor sheath black.

Female: fore wing length 10.4–13.6 mm.

Head

Clypeus almost flat, with a weak transverse ridge near apex; malar space 0.6× as long as basal mandibular width ( Fig. 8 ); lower face at narrowest point 0.9× as wide as height from clypeofacial suture to insertion of antenna; hypostomal carina strongly raised, joined by occipital carina far from base of mandible; posterior ocellus separated the eye by 1.3–1.4× its own maximum diameter ( Fig. 7 ); antenna with first flagellomere about 1.0× as long as the second; subapical flagellomeres slightly elongated.

Mesosoma

Pronotum with upper hind margin swollen, forming a small conical projection; scutoscutellar groove broad and shallow; scutellum shallow, with a few weak transverse rugae posteriorly; epicnemial carina more or less entirely absent ( Figs 1 , 5 & 10 ); sternal region of mesothorax smooth and polished; posterior transverse carina represented only by small lateromedian crests ( Fig. 7 ); metapleuron with a conspicuous sharp lateral projection near posterior end ( Figs 1 & 5 ); submetapleural carina narrow with a distinct low median denticle; propodeum in profile more or less flat; anterior transverse carina mediodorsally incomplete so area basalis is not enclosed posteriorly ( Fig. 7 ); area basalis slightly transverse; lateral longitudinal carina posteriorly weak or discontinuous ( Fig. 7 ); lateromedian longitudinal carinae joining anterior transverse carina at an angle of about 100 degrees, not present behind anterior transverse carina, even as a vestige ( Fig. 7 ); fore leg with tibia inflated, tarsus with long hairs on inner surface; mid leg with tibia bearing two or three stout spines on margin; hind coxa with anterior furrow deeply impressed, expanded ventrally, with a fringe of fine inconspicuous hairs; fore wing with areolet large, anteriorly pointed, with 2 m-cu joining it very slightly basal of middle ( Figs 1, 3 , 5 & 9 ); second distal cell short, with vein 1 m-cu about 0.5× the length of abscissa of Cu 1 between Rs&M and 1 m-cu ( Figs 3 & 9 ); hind wing with the distal abscissa of Cu 1 joining cu-a ( Figs 4 , 11 & 12 ).

Metasoma

Tergite I slender, 3.8–3.9× as long as posteriorly broad; sternite I short, reaching about 0.3 of length of tergite, with a weak median swelling centrally; tergite II 1.9–2.0× as long as broad, with isolated pubescence; tergite VII mediodorsally without an indentation posteriorly; tergite VIII, in lateral view, tapered to a bluntly rounded apex, without a cornus, and with uniformly scattered pubescence; tergite IX bearing long pubescence; ovipositor at rest extending beyond apex of metasoma by 3.6–3.8× the length of the hind tibia.

Color

A uniformly brownish orange species; flagellum black, with basal two flagellomeres ventrally reddish; tergite IX infuscate; ovipositor sheath uniformly blackish brown. Anterior two pairs of legs yellowish, hind leg orange with distal 0.7 of tibia and entire tarsus blackish. Fore wing hyaline, with a distinct subapical black spot; pterostigma black.

Male ( Figs 14–17 & 88 )

Similar to female in structure, size and colour, hind coxa unspecialized; lower margin of tergite VII slightly turned under, bearing sparse long straight hairs that have their extreme ends turned about 90 o; claspers with a fringe of scattered moderately long hairs; aedeagus compressed, obliquely truncate apically; subgenital plate bearing moderately close long pubescence.
