Ordo: Aciculata
Familia: Syllidae
Genus: Trypanosyllis
Name
Trypanosyllis vittigera Ehlers, 1887 – Wikispecies link – Pensoft Profile
- Trypanosyllis vittigera Hartman 1951[1]:41.–Uebelacker 1984[2]:88, fig. 82a–h.–San Martín 1991[3]:227–228.
Material examined
GCPG198, (4), fine sand, 1 m depth; GCPT106, (8), fine sand, 0.5–1.5 m depth.
Description
Length to 12.4 mm, width to 2.2 mm, with 56 chaetigers. Body long, and flattened; with two dorsal transverse brown stripes per segment anteriorly. Prostomium with a pair of lentigerous eyes in trapezoidal arrangement. Median antenna with 17–21 articles, lateral ones with 10–13 articles. Dorsal tentacular cirri with 29–36 articles, lateral ones with 19–23 articles. Dorsal cirri alternating in length longer, with 19–26 articles, and shorter, with 9–12 articles. Ventral cirri cirriform. Compound falcigers bidentate with small serrations, blades of dorsal falcigers longer than ventral ones (Fig. 2.20). Dorsal simple chaeta slender with subdistal small serrations (Fig. 2.21), and ventral simple chaeta bidentate, with subdistal serrations (Fig. 2.22), both only present on posterior chaetigers. Pharynx extending through 4–5 chaetigers, with distal trepan of ten teeth. Proventriculus extending through 4 chaetigers, with 31–37 rows of muscle cells. Pygidium with a pair of anal cirri with 6–9 articles.
Remarks
According to San Martín (1991)[3] Trypanosyllis zebra from the Mediterranean Sea is very similar to Trypanosyllis vittigera, differing only in the number of teeth on the trepan and in the length of the proventriculus, thus suggesting the need for a revision of Trypanosyllis zebra and related species.
Distribution
Circumtropical.
