The morphological ontogeny of Anachipteria magnilamellata (Ewing, 1909) is described and illustrated. The adult of this species lacks the anterior pteromorphic projection, and has 10 pairs of notogastral setae, with longer c₂ and la, and four pairs of porose areas, with the largest Aa. Genua I and II of A. magnilamellata have an anteroventral projection, seta v″ on femur II is longer than bv″, seta l′ on femur III is short and leg tarsi are heterotridactylous, with smooth claws. The prodorsal setae of juveniles are minute, except short rostral seta (ro), whereas the gastronotal setae are short or medium sized and barbed. Seta h₁ is absent from the larva. The leg segments of juveniles are stocky, and leg claws and most leg setae are smooth. Seta d at solenidion ϕ on tibia IV is present. The morphology of A. magnilamellata is compared with that of congeners. We consider Weigmanniella Subías, 2010 as a junior synonym of Anachipteria.
