Banyallarga (Histricoverpa) quincemil , new species

Figs. 29–30 View FIGURE 29 View FIGURE 30

Banyallarga quincemil is distinguished from B. acutiterga and sylvana by the acute apex of tergum X, which in B. quincemil is without apicoventral projections or dorsolateral lobes ( Fig. 29B View FIGURE 29 ). This new species is known only from Peru, while the other two species are Central American. The type specimens are rather badly rubbed, so details of coloration are unavailable.

Adult. Forewing length 10.5–11.1 mm (n=10).

Head golden brown. Maxillary palps golden brown. Antenna twice forewing length, golden brown. Forewing chestnut brown. Hind wing of male with basal semimembranous sleeve or pouch, enclosing brush of long setae; hind wing of female with short basal brush of pale setae.

Male. Lateral margin of sternum IV deeply excavated (as in Fig. 16 View FIGURE 16 ). Sternum VII with pointed anteromesal process. Tergum IX with anterior marginal ridge extending mesally to posterior margin, covered dorsally by semisclerotized membrane bearing dense fine pilosity ( Fig. 29B View FIGURE 29 ); lateral ridge present; dorsal pleural setae fine and numerous; ventral pleural setae approximately 10. Preanal appendage longer than tergum X, slightly wider at middle, apical 1/4 rugose, slightly flexible, covered with long fine setae ( Fig. 29A View FIGURE 29 ). Segment X shallowly emarginate posteriorly; with short rounded paired dorsolateral projections ( Fig. 29B View FIGURE 29 ); in lateral view apex of tergum roundly tapered. 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. 29C View FIGURE 29 ). Phallus with Ushaped phallotremal sclerite, thornlike setae on endothecal membrane ( Fig. 29D View FIGURE 29 ).

Female. Sternum VII with pointed anteromesal process. Sternum VIII anterior marginal ridge darkly sclerotized; fine setae covering posterior surface of sternite ( Fig. 30C View FIGURE 30 ). Tergum IX with anterior marginal ridge not extending posteromesally, posterior margin indistinct from tergum X ( Fig. 30B View FIGURE 30 ); sternum IX with anterior and posterior lobes darkly sclerotized and striate, smoothly sclerotized anteromesally, with tiny punctations posterolaterally. Tergum X semimembranous, appendage roundly tapered ( Fig. 30B View FIGURE 30 ); sternum X with semisclerotized plates bearing fine setae lateral to anal opening. Vaginal apparatus anterior sclerite truncate anteriorly, posterolateral projections short, rounded; posterior sclerite twice length of anterior sclerite, enclosed within a semisclerotized sheath; dorsal connective membrane with regular pleating ( Fig. 30A View FIGURE 30 ).
