 Diagnostic characters. A. pinhoi sp. n. differs from other species by the combination of the following characters: Male —expanded megaseta, gonostylus with 8 apical teeth, aedeagal complex with grooved aedeagal blade not beyond the basidorsal lobe, dorsal lobe absent; Pupa —wing sheath veins and spots absent, apex of aeropyle tube club-shaped, thoracic horn with spines only in the basal outer border, dorsal pore in A IV between setae D 3 and D 5, genital sac ending beyond the second anal macrosetae.
