Haplosyllis View in CoL sp.

Figure 2 View FIGURE 2 A–C

Material examined. Philippines. “Sepok Wall”, between Balayan Bay and Batangas Bay , dead coral, 2–3 m depth, Dec 2010, coll. M.T. Aguado, P. Álvarez-Campos, C. Russell, G. San Martín, 1 spec. ( MNCN 16.01 About MNCN /18730) .

Description. A very small incomplete specimen (12 chaetigers) ( Fig. 2A, C View FIGURE 2 , arrows), with 1-2 simple chaetae per parapodium; chaetae with short spur and two very long, strongly curved teeth, very close to each other, the subdistal with round tip, the distal with pointed tip ( Fig. 2B View FIGURE 2 ).

Remarks. The highly characteristic shape of the chaetae does not fit with any other described species of Haplosyllis . We only have a single, incomplete, minute specimen, and precludes a formal description. There are some other small, similar species in the Pacific, as Haplosyllis crassicirrata Aguado, San Martín & Nishi, 2006 , from Japan; however, that species has thick dorsal cirri, the distal teeth are more acute and more separated ( Aguado et al. 2006). Haplosyllis basticola Sardá, Ávila & Paul, 2002 , from Guam ( Micronesia) has the chaetae with shorter and not so curved teeth ( Sardá et al. 2002). Haplosyllis leylae Cepeda & Lattig, 2017 , from the Red Sea, is also a small species with short dorsal cirri, but the chaetae have longer and larger spurs and the teeth are not as long and curved as in the specimen from the Philippines ( Cepeda et al. 2017).

Habitat. The specimen has the everted pharynx attached to a posterior dorsal cirrus of a specimen of Syllis maganda n. sp.
