Trapeziidae Miers, 1886 View in CoL

Trapezia lutea Castro, 1997 ( Fig. 18 View FIGURE 18 A, B); Trapezia cymodoce (Herbst, 1801) ( Fig. 18 View FIGURE 18 C–F) and Tetralia glaberrima (Herbst, 1790)

The ossicles (I and II) are inclined about 45° in the antero ventral direction. The unpaired propyloric ossicle (VI) is nearly vertical. The pectinal ossicle (VIII) is horseshoe-shaped with four accessory teeth. The inferior lateral cardiac ossicle (XIII) has a connection-piece to the subdentate ossicle (XIV) antero dorsal. Ossicle XIXa is not recognisable.
