Banyallarga "n. sp. 1" Flint 1996b:424 As its name implies, B. echinata is distinguished easily from other known species by the presence of paired rows of prominent spinelike setae on the dorsal and lateral surfaces of tergum X ( Fig. 18B View FIGURE 18 ). Banyallarga nica is the only other species in Histricoverpa with spinelike setae on tergum X, but these are shorter, not arranged in rows, and located on the apices of long lateral lobes.

Adult. Forewing length 9.3–11.0 mm (n=11).

Head golden brown, with dorsomesal crest of dark brown setae. Maxillary palps golden brown. Antenna twice forewing length, golden brown. Dorsal pterothorax golden brown; ventrolateral thorax and femora golden brown, metathoracic tibia of male with long posterior setal fringe. Forewing mottled chestnut and gold. 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 short truncate posterior projection; dorsal pleural setae numerous; sternum IX with paired mesal ridges extending from anterior to posterior margin. Preanal appendages long, slightly flexible apically; apical 2/3 covered with long fine setae ( Fig. 19B View FIGURE 19 ). Segment X deeply emarginate posteriorly, forming two acute lateral projections; mesal and lateral margins bearing spinelike setae ( Fig. 19B View FIGURE 19 ). 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. 19C View FIGURE 19 ). Phallus with U­shaped phallotremal sclerite, thornlike setae on endothecal membrane ( Fig. 19D View FIGURE 19 ).

Female. Sternum VII with pointed anteromesal process. Sternum VIII anterior marginal ridge darkly sclerotized; fine setae covering posterior surface of sternite ( Fig. 20C View FIGURE 20 ). Tergum IX with mesal ridge extending only slightly from anterior margin, posterior margin marked by rounded lobes bearing fine pilosity ( Fig. 20B View FIGURE 20 ); sternum IX with anterior and posterior lobes darkly sclerotized and striate ( Fig. 20A View FIGURE 20 ). Tergum X semimembranous, appendage roundly tapered ( Fig. 20B View FIGURE 20 ); sternum X with semisclerotized plates bearing fine setae lateral to anal opening. Vaginal apparatus anterior sclerite truncate anteriorly, posterolateral projections acute, posterior portion folded beneath ventral surface; posterior sclerite enclosed within a semisclerotized sheath more than half width of posterior abdomen; dorsal connective membrane with regular, dense pleating ( Fig. 20A View FIGURE 20 ).
