( Figures 31 , 32 )

Hemigyroneuron suffusus Baker,1917: 325 .

Material examined

Holotype. Male , Philippines, “ Davao, Mindanao, Baker” ( USNM).

Morphology

Length of body 7.1 mm, and of fore wing 7.1 mm.

Head. (Antennae incomplete); transverse, 1.65 times wider than maximally long in dorsal view; width of head 2.6 times shortest distance between eyes; height of eye 1.6 times shortest distance between eyes; posterior ocellar line: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 1.0: 3.3: 1.7; occiput finely rugulose; occipital carina complete.

Mesosoma . Mesoscutum coriaceous-rugulose and densely short-setose, posteriorly with pair of short submedial longitudinal carinae; notauli hardly impressed, indicated by lines of coarser sculpture; mesopleuron with a slightly concave area with punctures somewhat confluent giving rise to slight ridged pattern; prepectal carina complete; scutellar sulcus with three carinae between the outer ones; scutellum entirely with fine longitudinal striation, and with lateral carinae (as extensions of lateral carinae of scutellar sulcus) largely complete; propodeum coarsely rugulose superimposed on aciculate sculpture, with complete mid-longitudinal carina, with well-defined ridge-like postero-lateral tubercles.

Fore wing. Subbasal cell glabrous with slightly oval distal part demarked by thickening and slight angulation of vein M+CU; without sclerome; vein 1-CU1 more or less equal to 2-CU1; vein cu-a greatly thickened anteriorly, narrowing and moderately curved posteriorly; length of veins r: 3-SR: SR1 = 1.0: 2.9: 4.7; vein m-cu 2.1 times length of 2-SR+M, forming an angle of 140 ◦ with 3-CU1; vein 2-M 3.0 times length of r-m.

Hind wing. Vein M+CU 3.0 times length of vein 1-M; vein 2-SC+ R marginally transverse; basal cell largely setose but glabrous posteriorly, subbasal cell largely glabrous, discal+subdiscal cell with glabrous area antero-basally.

Claws. Without conspicuous pecten. Metasoma. Tergite 2 1.35 times wider posteriorly than long, 1.73 times longer than 3rd, rather coarsely longitudinally striate with large punctures between striae. Male with conspicuous gland pore opening near mid-posterior margin of metasomal tergites 4–6.

Colouration

Entirely ochreous yellow. Wings hyaline slightly tinted with yellow, venation brownyellow except around junction of veins 3-CU1 and CU1a which is dark brown.

Notes

Closely related to A. (H.) roberti sp. nov. as indicated by the apomorphous very long hind wing vein M+CU relative to 1-M, despite entirely lacking sclerome in fore wing subbasal cell.
