Description

FEMALE TERMINALIA. Sternite VII ( Fig. 14A, C ), in ventral view, 2.2× as wide as long; posterolateral angles rounded and produced posterad; posterior margin with V-shaped notch at middle and deeply excavated laterad of broad median lobe, which occupies more than median third and is produced posteriorly, slightly surpassing lateral angles. Internal sternite VIII ( Fig. 14D ) partially sclerotized and with membranous portion pigmented. Pygofer ( Fig. 14A–B ), in lateral view, approximately 2.3× as long as high; macrosetae distributed on posteroventral quadrant; apex rounded. First valvifer ( Fig. 14E ) subelliptic, slightly higher than wide, anterodorsal and posteroventral angles rounded. First valvula ( Fig. 14E ) 10× as long as high; ventral interlocking device long, reaching apical fourth; dorsal sculptured area strigate; apical portion ( Fig. 14F ) gradually tapering to apex; apex acute and areolate. Second valvula ( Fig. 14G ) 12× as long as high; dorsal protuberance minute and rounded, localized before midlength of blade; apical portion ( Fig. 14H ) dorsal margin slightly excavated between dorsal protuberance and dentate apical portion, denticles small, approximately regular in shape and size and restricted to apical sixth; ventroapical margin with minute rounded denticles; apex rounded. Second valvifer ( Fig. 14I ) 2.5× as high as wide. Gonoplac ( Fig. 14I ) 5× as long as high; dorsoapical margin straight, longer than one-third of gonoplac length; ventral margin evenly rounded, with a few short setae; outer surface ( Fig. 14J ) with many integumentary denticles; rounded apex.
