 Diagnostic characters. A. laurindoi sp. n. differs from other species by the combination of the following characters: Male —tapered megaseta, dorsal lobe absent, aedeagal blade with broad base and aedeagal complex completely covered by anal point; Pupa —apex of aeropyle tube club-shaped, thoracic horn with spines in the outer lateral, dorsal pore in A IV between setae D 3 and D 5, genital sac 360 µm long, wing sheath with spots and complete veins; Larva —head capsule elongated and without spots, ligula teeth in concave arch, dorsal pore present, posterior parapod with 3 brown claws, procercus brown and with 7 anal setae.
