Tarasovium orientale Ren, 1983: 76 , fig. 1 (13–23). — Liu & Ren, 1985: 201, pl. 2 (15–17). — Liu & Ren, 2007:

246–247, fig. 106.

Material examined. NMNS 005734-00009, 1 specimen, benthic trawl, Tainan County, south west Taiwan (15 Aug. 2005, depth unknown), CL 32.05 mm, CW 21.07 mm, PL 18.66 mm.

Diagnosis. 14 capitular plates, fully calcified; upper latus pentagonal, umbo sub-apical; inframedian latus quadrilateral, umbo close to basal margin; carinolatus horn-shaped, umbo at basicarinal angle, angle extending beyond carina.

Description. Capitulum pale yellow ( Fig. 1 View FIGURE 1 D), subtriangular, with 14 fully calcified plates, covered by membrane, with sparse setae ( Fig. 1 View FIGURE 1 D); tergum triangular, umbo apical, occludent and basal margins slightly convex, carinal margin straight; scutum quadrangular, small apex extending beyond margin of tergum, umbo apical, occludent margin convex, basal and upper latus margins concave ( Fig. 1 View FIGURE 1 D); upper latus pentagonal, umbo subapical ( Fig. 1 View FIGURE 1 D); rostrolatus narrow quadrangular, wider than high ( Fig. 1 View FIGURE 1 D); inframedian latus broad, rectangular, umbo close to basal margin ( Fig. 1 View FIGURE 1 D); carinolatus horn-shaped, umbo at basi-carinal angle, angle extending beyond carina; carina convex, umbo apical ( Fig. 1 View FIGURE 1 D). Maxilla subtriangular, dense setae along entire margin ( Fig. 6 View FIGURE 6 A); maxillule not notched, cutting edge with numerous setae ( Fig. 6 View FIGURE 6 B); mandible with 6 teeth excluding inferior angle ( Fig. 6 View FIGURE 6 C), lower margin straight, smooth, without setae, inferior angle setose ( Fig. 6 View FIGURE 6 C); mandibular palp elongated, dense setae along superior margin ( Fig. 6 View FIGURE 6 D), inferior margin naked. Cirrus I with rami unequal ( Fig. 6 View FIGURE 6 E), separated from cirri II–VI, outer ramus slender, longer (13- segmented), inner ramus broader, shorter (9-segmented); cirri II–VI similar in morphology ( Fig. 6 View FIGURE 6 F), outer and inner rami similar lengths, 18–20 segmented; caudal appendage short, 1-segmented, length <height of basal segment of pedicle of cirrus VI.
