Systematics: The adult female of A. haywardi Juarez & González resembles that of A. dubius (Cockerell), but differs in that the latter species has (character-states for A. haywardi in brackets): (i) five setae on the metathoracic tibiae (four); (ii) six setae on the prothoracic tibiae (five); (iii) dorsal setae arranged in longitudinal bands (in lines parallel to intersegmental lines); (iv) one type of microtubular ducts (two types); (v) several cruciform pores on the abdomen (absent); (vi) ventral conical setae present (absent), and (vii) that it lacks a sclerotized anal tube (anal tube present). Although A. dubius, which has been recently found in Brasil on Calliandra sp. and in Venezuela on Prosopis sp. (Foldi & Kozár 2007), is a highly variable species, the above combination of character-states is considered to be sufficient to separate the two species. (González, et al., 2017)
Structure: Adult female. Dorsal setae each conical with an acute apex; macrotubular ducts symmetrical and very large. Margin with 2 setae on each abdominal segment and on metathorax. Ventral surface with enlarged conical setae absent; microtubular ducts absent; quinquelocular, trilocular and cruciform pores sparse; metathoracic coxa with about 50 pores; metathoracic tibia with 4 setae and prothoracic tibia with 5 setae. (González, et al., 2017)
