Lepidopterous insects in the Collection of the British, 31 (70): 521; species included: Iza nubecula ( Guenée, 1858) View in CoL , Iza botydana Walker, 1865 View in CoL , Iza View in CoL ? terminalis Walker, 1865, Iza perlula ( Guenée, 1858) .— Guenée, 1877. Annales de la Société Entomologique de France, (5) 7: 301.—Druce, 1895, in Godman & Salvin.

Type species: Siculodes nubecula Guenée, 1858 View in CoL by subsequent designation ( Guenée 1877) (“Cette espèce deviendra par la suite le type d’un genre ( Iza Walk. View in CoL ) que je n’ai pas cru devoir adopter dans l’état imparfait de la science”). This fact was later confirmed by Druce (1895).
Taxonomic history. Iza View in CoL was described to include the following species: I. nubecula View in CoL , I. botydana View in CoL , I.? terminalis and I. perlula , but without designation of the type species. Currently, the only species in the genus is the type species. Iza botydana View in CoL was transferred by Whalley & Heppner (1995) to Pseudendromis Köhler, 1924 View in CoL as I.? terminalis and I. perlula was transferred by Hampson (1897) to Rhodoneura Guenée, 1858 View in CoL .
Diagnosis. Iza is distinguished from the remaining genera of Siculodini by: (i) wings dark brown ground color with irregular beige patches and bands dorsal and ventrally ( Fig. 2 View FIGURES 1–2 ); (ii) abdomen dark brown on the dorsal face and beige on the ventral face; (iii) valva triangular; (iv) valva with spiniform process; (v) fultura inferior U-shaped; (vi) aedeagus narrowing distally with spines; (vii) lamella antevaginalis sclerotized and (viii) papillae anales straight.
Redescription. Forewing: length—males 16.6 mm (n = 11), females 25.4 mm (n = 5); slightly concave tornus; retinaculum absent.
Hindwing: length—males 12.6 mm (n = 11), females 15.8 mm (n = 5); apex right angled and tornus concave; male with sand-colored patch on the costal margin ventrally; frenulum absent.
Male genitalia ( Fig. 6 View FIGURE 6 ): tegumen with proximal and distal margins convex in dorsal view; saccus oval in lateral view; uncus triangular in dorsal view, with thin and short setae; gnathos reduced and distally sclerotized, projected disto-ventrally; valva triangular, costa slightly concave, spiniform process in the proximal part, clasper projected dorsally, apex rounded and ventral margin convex, slightly concave at the posterior end of sacculus; fultura inferior U-shaped, broad and thickly sclerotized arms with blunt apex and short setae; aedeagus cylindrical, proximal half thicker, narrowing distally with numerous spines, opening for the vesica extending along the entire posterior half, vesica without cornutus.
Female genitalia ( Fig. 10 View FIGURES 9–12 ): tergum VIII rectangular in lateral view, lamella antevaginalis sclerotized, ostium membranous; posterior apophyses longer than the anterior apophyses; bursa copulatrix with sclerotized wide ductus at anterior 1/4, second 1/4 membranous and narrow, and posterior half membranous and slightly thicker, corpus bursae membranous, without signum; papillae anales straight, taller than long and covered with short and thin setae.
