( Figs 6 View FIGURE 6 C, 12–14)
Redescription of trophi. Trophi malleoramate ( Figs 12 View FIGURE 12 , 13 View FIGURE 13 ). Frontal latero-ventral margins of rami with a large, quadratic and stout reinforced, caudally recurved alula ( Figs 12–14 View FIGURE 12 View FIGURE 13 View FIGURE 14 : al). Median rami apophyses ( Fig. 12 View FIGURE 12 B: ra) weakly developed. Inner margins distal rami sections bearing 14–21/13–21 strongly webbed arched rami scleropili ( Figs 12 View FIGURE 12 B, 14A: as). Frontal rami scleropili with fairly acute distal tip ( Fig. 14 View FIGURE 14 B: fs). Basal apophyses moderately developed ( Fig. 13 View FIGURE 13 : ba). Fulcrum short with a distinct proximal opening frontally ( Fig. 13 View FIGURE 13 : fo). Unci plates ( Fig. 12 View FIGURE 12 A: u) consist of 11–13/11–12 weakly curved and strongly webbed teeth. Each uncus has 3, occasionally 4, major teeth with moderately offset lanceolate heads. Minor teeth with lanceolate head bearing two minute lateral knobs at their base; the webbing almost extends up to the base of the heads. Crescent-shaped manubria are composed of a superimposed dorsal, median, ventral and small sub-ventral chamber ( Fig. 12 View FIGURE 12 B).
Measurements. Trophi (N = 6): length × width 17.4–20.4 × 22.4–24.5 µm, ramus 10.7–12.1 µm, fulcrum 5.2– 6.1 µm, largest major tooth 10.0–10.6 µm, manubrium 10.7–12.4 µm.
