This subspecies resembles Panesthia angustipennis spadica, and it is difficult to distinguish adults. Roth (1979) stated Panesthia angustipennis spadica had a deflexed hind margin of the supra-anal fig and appeared to be entire dorsally, not deflexed and with teeth visible dorsally in Panesthia angustipennis cognata. Despite this character being variable, some of the populations were sufficiently different, and distinct on average. It is significant that L2d of median phallomere in Panesthia angustipennis cognata is short with variable apex, but elongate and tapering to a round apex in Panesthia angustipennis spadica. Nymphs of Panesthia angustipennis cognata have a broadly yellowish marking on mesonotum and metanotum (Fig. 25) while Panesthia angustipennis spadica is with or without two markings on mesonotum, and without any markings on metanotum.
