Comments. Spinaria indica differs from S. vietnamica in having diameter of antennal sockets about twice as long as distance between them (vs 1.4 × in S. vietnamica); malar space nearly as long as basal width of mandible (vs 0.4 × in S. vietnamica), vein cu-a of fore wing about 1.9 × 1-CU1 (vs 2.3–2.5 × in S. vietnamica); ovipositor sheath 0.7 mm (vs 1.2 mm in S. vietnamica); marginal cell, second and third submarginal cells fully infuscated (vs basal half of marginal cell and second submarginal cell yellowish in S. vietnamica).
