Type locality. Bohol, Philippines .
Material examined. HOLOTYPE: ZMB 10654. Philippines, Bohol, leg Semper, coll. Grube.
Description. Holotype poorly preserved with body wall damaged but parapodia and chaetae mainly intact, yellowish brown in colour, consists of five fragments that do not constitute an entire animal, all fragments only a few mm long; an anterior fragment consisting of 8 segments, mid-body fragment of 2 chaetigers, mid-posterior fragment of 12 chaetigers, and an extreme posterior fragment consisting of about 23 segments. Sex unknown.
Dorsum anteriorly smooth. Venter anteriorly with mid-ventral groove and poorly defined ventro-lateral pads; pads more-or-less smooth with few papillations anteriorly. Mid-ventral groove divided into small shields, from segment 3 to 5 ( Fig. 11a View FIGURE 11 ).
Buccal tentacles of two types ( Hutchings & Glasby 1986): (1) cylindrical, thickened distally, distinctly grooved (these now missing on type, see Fig. 11a View FIGURE 11 ) and (2) cylindrical, uniformly thin, weakly grooved; both types arising at junction between prostomium and upper lip. Prostomial ridge slightly curved, extending laterally. Upper lip trefoiled, with lateral, blindly ending, enclosed diverticulae (surface of diverticula with many small tentacles), margin of medial lobe thickened and overturned; oral surface glandular and ciliated. Inner lower lip oblong, smooth; outer region with subconical lobe protruding above venter, recurved posteriorly, smooth. Achaetous segments visible dorsally but obscured ventrally.
Notochaetigerous segments 10 or 11, extending to segments 12 or 13. Notopodial prechaetal lobe low, postchaetal lobe digitiform, longer than prechaetal ( Fig. 11b View FIGURE 11 ). Notochaetae within a chaetiger of two types (anterior body chaetiger examined), pinnate, posteriorly same form as those anteriorly; secondary notochaetae in all chaetigers smooth, narrowly winged, uniformly tapered ( Fig. 11c–e View FIGURE 11 ). Neurochaetae beginning on segment 14. Neuropodial tori ridge like, similar along body. Uncini with long neck and concave base (Type 2), teeth above main fang arranged in double transverse series (MF:1:8), enlarged median tooth above main fang present, subrostral process absent ( Fig. 11f–g View FIGURE 11 ).
Nephridial papillae not visible.
Comments. Hutchings & Glasby (1986) redescribed this species based on the holotype and additional specimens from NE Australia. They reported that neurochaetae begin from segment 13–15 and that the holotype had 10 or 11 notochaetigerous segments, although Grube mentions 12, possibly 13 ( Table 1 View TABLE 1 ).
