Banyallarga fortuna and B. tapanti are the only species of Histricoverpa that have the apex of tergum X rounded in lateral view ( Figs. 21A View FIGURE 21 , 35A View FIGURE 35 ). Banyallarga fortuna is distinguished from B. tapanti by the absence ( Fig 21A, B View FIGURE 21 ) of the dorsomesal ridge present on the tergum X of B. tapanti ( Fig. 35A, B View FIGURE 35 ).

Adult. Forewing length 8.4–9.9 mm (n=6).

Head golden brown. Maxillary palps golden brown. Antenna twice forewing length, chestnut brown, each flagellomere pale basally and with narrow patch of pale sensilla on anterior surface. Dorsal pterothorax golden brown; ventrolateral thorax and legs golden brown, metathoracic tibia of male with long posterior setal fringe. Forewing mottled chestnut and golden brown. Hind wing of male with basal semimembranous sleeve or pouch, enclosing brush of long setae.

Male. Lateral margin of sternum IV deeply excavated (as in Fig. 16 View FIGURE 16 ). Sterna VI and VII with pointed anteromesal processes. Tergum IX with distinct anterior marginal ridge; dorsal pleural setae numerous. Preanal appendages much longer than tergum X, slightly flexible apically; apical 2/3 covered with long fine setae ( Fig. 21A View FIGURE 21 ). Segment X shallowly emarginate posteriorly ( Fig. 21B View FIGURE 21 ), forming two short rounded lateral projections; in lateral view posterior margin rounded. Inferior appendage simple, with long setae ventrally and laterally on coxopodite; harpago of uniform diameter along length, with fine setae basally and peglike setae apically ( Fig. 21C View FIGURE 21 ). Phallus with U­shaped dorsal phallotremal sclerite, ventral sclerite a short, indistinct sclerotized tube, thornlike setae cover ventral and anterolateral surface of endothecal membrane ( Fig. 21D View FIGURE 21 ).

Female. Sternum VII with pointed anteromesal process. Sternum VIII anterior marginal ridge darkly sclerotized; short stout setae in two rows on posterior margin ( Fig. 22C View FIGURE 22 ). Tergum IX without mesal ridge, posterior margin rounded ( Fig. 22B View FIGURE 22 ); sternum IX with anterior and posterior lobes darkly sclerotized and striate. Tergum X semimembranous, appendage roundly tapered ( Fig. 22B View FIGURE 22 ); sternum X with semisclerotized plates bearing fine setae lateral to anal opening ( Fig. 22A View FIGURE 22 ). Vaginal apparatus anterior sclerite shallowly emarginate anteriorly, posterolateral projections short; posterior sclerite ovoid ( Fig. 22A View FIGURE 22 ).
