Fore wing: pterostigma 5.2 times longer than wide (52:10); r:2-SR:3-SR:SR1=12:9:32:38; vein r arising little before middle of pterostigma; vein cu-a short and robust (Fig. 16), 1-CU1:cu-a:2-CU1:3-CU1=3:7:31:6; posterior length of second submarginal cell 2.7 times its apical width (40:15). Hind wing: vein M+CU:1-M: 1r-m=32:30:11.

Legs. Hind coxa shining with sparse fine punctures; length of hind femur:tibia:basitarsus: tarsus = 32:43:22:50; length of hind femur, tibia and basitarsus 5.3, 9.5 and 11.0 times as long as their width respectively; inner hind tibial spur 0.25 times as long as basitarsus (11:44).

Pale yellow; antenna yellow; palpi whitish yellow; stemmaticum black; pronotum, mesopleuron, metapleuron pale yellow; hind coxa blackish dorsally and ventrally, yellow basally and ventrally; propodeum laterally, metasomal tergites 1-5 basally and tergite 6 entirely, black; wing subhyaline with brownish yellow veins, setae pale yellow; pterostigma dark brown medially, yellow basally and apically (Fig. 16).

Male.

Unknown.

Variation.

Paratypes, antenna with 44-52 segments; first tergite 1.35-1.45 times as long as apical width; medial length of metasomal second tergite 1.5-1.6 times as long as third tergite medially; body length 5.6-8.0 mm; fore wing length 4.6-5.9 mm.

Etymology.

Named ‘affinis’ (Latin for 'related to’), because this species is close to Canalirogas spilonotus (Cameron).
