Remarks. Though body forms are similar, females of these two paradoxosomatids can be reliably identified based on the midbody paranota, whose caudolateral margins are prolonged and acuminate in A. coarctata and flat, subcontinuous with the caudal metatergal margins, and apically blunt in O. gracilis ( Shelley and Lehtinen 1999, figs. 1, 4). This distinction holds for the midbody region only, around segments 9–13; the caudal paranota resemble each other with those of O. gracilis becoming progressively prolonged and acuminate caudally, particularly in Saban specimens.
