Diagnosis. Carina strongly bowed; tergum triangular; scutum with umbo at tergo-occludent angle; inframedian latus pentagonal, umbo sub-basal; carinolateral horn-shaped, umbo at basicarinal angle, angle extending beyond carina.
Description. Capitulum almost square-shaped; 14 perfectly calcified plates, covered by yellow membrane ( Fig. 2 View FIGURE 2 C); tergum triangular, umbo apical, tergal margin slightly convex ( Fig. 2 View FIGURE 2 C); scutum quadrilateral, lateral margin concave ( Fig. 2 View FIGURE 2 C); upper latus pentagonal ( Fig. 2 View FIGURE 2 C); inframedian latus pentagonal, smaller than upper latus, umbo submedial ( Fig. 2 View FIGURE 2 C); carinolatus strongly curved, horn-shaped, extending beyond carina, umbo apical ( Fig. 2 View FIGURE 2 C); rostrolatus wider than high, narrow; rostrum small ( Fig. 2 View FIGURE 2 C); carina strongly bowed, thick. Peduncle long, cylindrical, covered by calcified scales ( Fig. 2 View FIGURE 2 C); peduncular scales arranged in concentric patterns ( Fig. 2 View FIGURE 2 C). Maxilla subtriangular with fine setae ( Fig. 18 View FIGURE 18 A); maxillule without a clear notch,> 35 strong cuspidate setae on cutting edge ( Fig. 18 View FIGURE 18 B); mandible with 5 major teeth excluding inferior angle ( Fig. 18 View FIGURE 18 C), lower margin with fine denticles, inferior angle terminating in dense setae ( Fig. 18 View FIGURE 18 C); mandibular palps elongated, narrow, with serrulate-type setae on superior margin ( Fig. 18 View FIGURE 18 D); labrum strongly V-shaped, with fine teeth on cutting edge. Cirrus I with rami unequal, inner ramus oval (12-segmented), outer ramus long, slender (18-segmented) ( Fig. 18 View FIGURE 18 E); cirri II–VI similar in morphology, rami almost equal length, outer and inner rami 25–36-segmented ( Fig. 18 View FIGURE 18 F); caudal appendages short, 5–6 segmented ( Fig. 18 View FIGURE 18 G).
