Taxonomic history. Warren (1900) described the species based on a female [holotype] without illustration from Costa Rica. Transferred to Risama by Dalla Torre (1914) and to Siculodes by Whalley & Heppner (1995).

Taxonomic comments. After analyzing the morphology of the holotype and wing morphology (shape and venation), S. substrigata comb. rev. does not belong to Siculodes but to Aziba gen. rev., and for this reason, its original combination is herein revalidated.

Type material. A female [holotype] was found in NHMUK, with the author’s original labels matching the information provided in the original description: / Aziba substrigata Type ♀ Warr / Costa Rica / Rothschild Bequest B.M.1939-1. / Type / Holotype / BMNH (E) 1377137 / NHMUK 010921241 /.

Diagnosis. Aziba substrigata comb. rev. can be easily distinguished from all its congeners by wings overall light brown, as the tegulae, with irregular brown spots and lines intensifying on inner margin ( Figs 9A–D ) and valve with straight costal margin as in A. falcata comb. rev., but in the latter both margins are straight. In addition, by combination of the following characters: i) saccus elongated ( Fig. 16B ); (v) gnathos U-shape ( Fig. 16A ) and iii) signum rectangular ( Fig. 35 ).

Redescription. Forewing: length—male 21.0–26.0 mm (n = 3), female 22.0–33.0 mm (n = 3); both surfaces with oblique postdiscal brown stripe from M 1 to half of inner margin, intensifying color near to inner margin; veins R 3 +R 4 bifurcates half of costal margin.

Hindwing: length—male 12.0–15.0 mm (n = 3), female 15.0–20.0 mm (n = 3); both surfaces with a brown transverse stripe from middle of coast margin to inner margin, intensifying color on ventral surface; outer margin straight.

Male genitalia ( Fig. 16 ): tegumen rectangular in dorsal view and with convex margins; saccus elongated; gnathos U-shaped in posterior view; valva with costa straight, ventral margin sinuous, narrowing obliquely from middle; fultura inferior with inverted horseshoe-like; aedeagus as long as valva, slightly curved ventrally, elongated dorsal opening for ductus ejaculatorius, vesica without cornutus.

Female genitalia ( Fig. 25 ): tergite VIII square in lateral view; anterior apophysis twice as long as posterior apophysis; bursa copulatrix membranous except by short sclerotized antrum, ductus bursae ten times longer than antrum, signum rectangular with a median constriction, covered with spinules ( Fig. 35 ).
