( Figs 1–3 View FIGURE 1 View FIGURE 2 View FIGURE 3 )
Materials examined. Holotype, ASIZCR 0 0 0 202, Dong-Qing-Wan, Lanyu Island, Taiwan (22°01’, 121°32’), 5–10 m, coll. B.K.K. Chan; paratype, ASIZCR 000203-205, data same as holotype.
Diagnosis. Wall with approximately 20 internal ribs; lengths of scutal basal and tergal margins subequal; tergum with broad spur, external spur furrow shallow, spur length approximately 1/2 length of scutal margin.
Description. Parietes slightly projecting above coral surface, covered by coral skeleton overlying external ribs, number of ribs indistinct ( Fig. 1 View FIGURE 1 A, B). Rostro-carinal diameter to 4 mm; wall of 4 parietes, approximately 20 internal radial ribs radiating from central orifice, some secondary ribs reaching 1/2 way between wall circumference and orifice ( Fig. 1 View FIGURE 1 C); tubes between sheath and parietes largely filled. Orifice oval; 1/5 of rostro-carinal diameter. Sheath pigmented, orange, with concentric growth ridges extending more than 1/2 way down internal surface of parietes ( Fig. 1 View FIGURE 1 C). Carina wider than rostrum. Basis white, solid, thin, shallow cup-shape.
Opercular valves thin, orange-red. Scutum triangular, basal margins slightly longer than tergal margins; externally growth ridges coarse, crossed by fine striae, alternate ridges forming teeth on occuludent margins ( Fig 1 View FIGURE 1 D, F). Tergal portion of scutum inflected. Apical angle approximately 60°, 11–14 rows of round pits at apical angle forming honeycomb-like surface ( Fig. 1 View FIGURE 1 E). Basal margins sinusoidal. Internally adductor ridge not extending beyond basal margin. Pit of lateral depressor muscle small; rostral tooth absent.
Tergum ( Fig. 1 View FIGURE 1 G, I) with blunt spur, spur width approximately 1/2 tergal width, external furrow shallow, open from apex to spur base, angle between spur and basal margin obtuse. Pits similar to those on Scutum, forming honeycomb-like surface at apex ( Fig. 1 View FIGURE 1 H). Sinusoidal, fine growth ridges on tergum surface. Tergal wing height approximately 1/2 tergal length (including spur). Internally small pits for tergal depressor muscle present ( Fig. 1 View FIGURE 1 I).
Trophi: Mandibles with quadridentoid cutting edge ( Fig. 2 View FIGURE 2 A), 2nd and 4th teeth bidentate, first 3 teeth occupying more then 3/4 length of cutting edge ( Fig. 2 View FIGURE 2 C). Lower mandibular margin smooth, without fine setae or spines ( Fig. 2 View FIGURE 2 A). Lateral side of mandible bearing serrulate setae with fine setules ( Fig. 2 View FIGURE 2 B). Labrum with deep, V-shaped notch, 2 large teeth on each side of notch ( Fig. 2 View FIGURE 2 D). Maxillule straight, row of 9 strong spines of differing sizes ( Fig. 4 View FIGURE 4 E), serrulate setae at base of large spines ( Fig. 2 View FIGURE 2 F). Mandibular palp and maxilla bearing serrulate setae with short and dense setules ( Fig. 2 View FIGURE 2 G, H, I, J).
Cirri: Cirrus I with rami unequal, exopodite of 13 articles, endopodite of 5 ( Fig. 3 View FIGURE 3 A). Setae on rami serrulate ( Fig. 3 View FIGURE 3 B) with dense setules. Protopodite bearing serrulate setae with sparsely distributed setules ( Fig. 3 View FIGURE 3 C). Cirrus II with expopodite and endopodite similar length, 6–7 articles ( Fig. 3 View FIGURE 3 D), rami bearing serrate setae with 3 rows of setules ( Fig. 3 View FIGURE 3 E, F), setules distally curved, sharply pointed ( Fig. 3 View FIGURE 3 F). Cirrus III with exopodite and endopodite thin ( Fig. 3 View FIGURE 3 G), rami bearing serrate setae with 3 rows of setules ( Fig. 3 View FIGURE 3 H). Protopod bearing plumose setae with long setules ( Fig. 3 View FIGURE 3 C, I). Cirri IV–VI similar ( Fig. 3 View FIGURE 3 J), articles of rami with 2–3 pairs of thin, serrulate setae, distal pair longest ( Fig. 3 View FIGURE 3 K).
Etymology. The species is named in honor of Jens T. Høeg’s (University of Copenhagen, Denmark) in recognition of his contribution to the study of cirripede phylogeny.
