Figs. 23–24 View FIGURE 23 View FIGURE 24
This species is known only from two specimens. It is unique within Histricoverpa due to the easily recognizable long, paired, apically bifurcate posterior projections of tergum X ( Fig. 23A, B View FIGURE 23 ).
Adult. Forewing length 13.0– 13.3 mm (n=2).
Head golden brown. Maxillary palps golden brown. Antenna golden brown, base of each flagellomere pale. Dorsal pterothorax golden brown; ventrolateral thorax and femora golden brown, metathoracic tibia of male with long posterior setal fringe. Forewing uniform golden brown.
Male. 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. 23B View FIGURE 23 ); lateral ridge incomplete posteriorly; anterior marginal ridge of sternum extending slightly posteriorly. Preanal appendages long, broadening from base and constricting subapically, slightly flexible apically; apical 2/3 covered with long fine setae ( Fig. 23B View FIGURE 23 ). Segment X deeply cleft posteromesally, forming two long, apically bifurcate lateral projections; in lateral view, ventral margin concave and posterior projection long and narrow ( Fig. 23A View FIGURE 23 ). 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. 23A View FIGURE 23 ). Phallus with Ushaped phallotremal sclerite, thornlike setae on endothecal membrane (23D).
Female. Sternum VII with pointed anteromesal process. Sternum VIII anterior marginal ridge darkly sclerotized; fine setae covering posterior surface of sternite (24C). Tergum IX with anterior marginal ridge extending only slightly mesally, posteromesally indistinct from tergum X ( Fig. 24B View FIGURE 24 ); sternum IX with anterior and posterior lobes darkly sclerotized and striate; with tiny setae posteriorly ( Fig. 24A View FIGURE 24 ). Tergum X semimembranous, appendage truncate apically ( Fig. 24B View FIGURE 24 ); sternum X with semisclerotized plates bearing fine setae lateral to anal opening. Vaginal apparatus anterior sclerite rounded anteriorly, posterolateral projections short and rounded; posterior sclerite longer than anterior, constricted at anterior margin of sternum IX; dorsal connective membrane distinct ( Fig. 24A View FIGURE 24 ).
