Geographic records. Known only at municipality of Manaus, state of Amazonas, Brazil.
Habitat, calling site and calling song. Males and females live on trunks above three meters high. Two males were found stridulating in this habitat, but it was not recorded in field. These males were kept in laboratory by seven days, but it did not sing.

Holotype condition. Left leg III absent (lost); detached right tegmen; genitalia placed in microvial with glycerin; right tegmen and genitalia are maintained in holotype's tube.
Comments. In this work we suggest the delimitation of five important projections in the male genitalia: (i) apical projection of the lateral epiphallic arm (*ap); (ii) dorsal apical projection of the lateral epiphallic arm (*ap.d); (iii) ventral apical projection of the lateral epiphallic arm (*ap.v), (iv) subapical projection in the inner margin of lateral epiphallic arm (*sp) and (v) projection in the hind lateral lobe of median epiphallic bridge (*ph). These delimitations are not a proposed nomenclature. They are to facilitate the description of the structures. In A. crybelos n. comb. there is only one apical projection in the lateral epiphallic arm. Thus, the projection received no consideration about its dorsal or ventral position as occurred with A. manauensis n. sp.
