( Figure 14 View FIGURE 14. A – C L, Figure 18 View FIGURE 18 A–E)

Vermiliopsis glandigerus Gravier, 1906: 121 .

Vermiliopsis glandigera — Pillai 2009: 104 –108.

Vermiliopsis infundibulum / glandigera group—Imajima 1976 a: 139–141; Mak 1982: 610–611; Imajima and ten Hove 1984: 59; Fiege and Sun 1999: 134 –135; Sun and Yang 2001 a: 203 –204.

Material examined. AM W41415 View Materials , 2 specimens (22 ° 21 ’N, 114 ° 17 ’E, Sharp Island, on dead coral, 3 m, May 21, 2009).

Description. TUBE: white, with 6 longitudinal ridges. Circular in cross-section. Up to 0.9 mm wide with lumen 0.7 mm.

BRANCHIAE: each lobe with 6 pairs of radioles; terminal filaments short. Branchial eyes absent.

PEDUNCLE: circular in cross-section, inserted just below right branchial lobe, with 4 to 5 annuli anteriorly, uppermost one inflated. Pseudo-operculum absent.

OPERCULUM: operculum consisting of a bulbous translucent fleshy ampulla, and a round conical, translucent chitinized cap with three internal septa ( Figure 14 View FIGURE 14. A – C L). Opercular length: from 1.1 mm to 1.2 mm (n= 2, µ= 1.1 ± 0.1), width of both specimens 0.6 mm (n= 2, µ = 0.6 ±0).

COLLAR AND THORACIC MEMBRANES: collar trilobed, lateral lobes larger, continuous with narrow thoracic membranes extending to chaetiger 4.

THORAX: with 7 chaetigers, 6 uncinigerous. Collar chaetae of two types: limbate, with serrated blades and slender capillaries ( Figure 18 View FIGURE 18 A). Chaeta of segment 2 similar to collar, chaetigers 3 to 7 with Apomatus chaetae in addition ( Figure 18 View FIGURE 18 B–C). Uncini along entire thorax saw-shaped, with 12 curved teeth and rounded peg ( Figure 18 View FIGURE 18 D). Tori of similar size along thorax.

ABDOMEN: Uncini saw-shaped anteriorly, with 11 teeth and blunt peg ( Figure 18 View FIGURE 18 E). Anterior abdominal chaetae flat narrow geniculate with blunt teeth. Posterior abdominal chaetae capillary.

SIZE: total lengths of worms: 10.3 mm to 12.6 mm (n= 2, µ= 11.4 ± 1.6), thoracic widths: 0.6 mm to 0.8 mm (n= 2, µ= 0.7 ± 0.2). Branchiae and operculum accounting for one fifth of entire length.

COLOUR: in ethanol yellowish, with brown pigmentation on branchial crown and thoracic neuropodia.

Habitat. Depth: 3 m, on dead corals.

Remarks. Ten Hove (1975) considered Vermiliopsis infundibulum / glandigera to be a species complex. In a recent study, Pillai (2009) attributed the western Pacific specimens of this complex to V. glandigerus , which we have followed in this paper. However, for a more detailed discussion of the taxonomic problems in this genus see ten Hove & Kupriyanova (2009: 100) and Ben-Eliahu and ten Hove (2011: 95).

Distribution. Tropical and subtropical waters of western Pacific Ocean.
