Male genitalia. Pygofer broad with stout macrosetae distributed near midlength towards posterad margin ( Figure 7 (a–b)). Valve medially producedı articulated with pygofer and subgenital plates ( Figure 7 (c)). Plate thinı length similar to posterad margin of pygoferı few small fine and stout setae along lateral margin ( Figure 7 (d)). Style slender with posterad lobes weakly developedı apophysis short and curved ( Figure 7 (h)). Connective Y-form ( Figure 3 (i)). Aedeagus robustı short and apex pointed with broad lateral flanges developed with two apical processes; one emerging of distant flange corner directed dorsad and second arising near apex on ventral surface running ventromesad until midlength of aedeagal shaftı cylindrical ( Figure 7 (e–g)).

Immature stages. Unknown.

Type locality. Iguala de la Independenciaı Guerrero ( Mexico)ı Figure 4 . Seasonality. This species occurs in October .

Etymology. The species epithet derives from the Náhuatl word Igualaı meaning to the type locality.

Type material. Holotype male ( OSUC) – MEXICO: Guerreroı Igualaı IX–11– 1939ı D. M. DeLong Collectionı D. M. DeLong Coll. # OSUC 356605 . Paratype 2 males ( OSUC) – MEXICO: Guerreroı Igualaı IX–11– 1939ı D. M. DeLong Collectionı D. M. DeLong Coll. # OSUC 356606 and 356607ı respectively .

Note: all specimens examined were previously designated as paratypes of Devolana hemycicla DeLong by DeLong (1967).
