A Preliminary Study on the Family Paraonidae (Polychaeta) from the Huanghai Sea (Yellow Sea)
Zhao Jing Wu Baoling (First Institute of Oceanography, SOA, Qingdao)
During the benthic investigation of the islands along the coast of Shandong from 1987 to 1988, 5 species of the family Paraonidae including one new subspecies and three first recorded species from China were found.
1. Aricidea (Allia) quadrilobata Webster and Benedict
One specimen collected from Toudao near Qindao. Length of incomplete specimen 6.Smm with 36 ehaetigers, width 0.36mm not including ehaetae. Prostomium trilobed; middle lobe longer than the lateral ones (Fig. 1, a). Unpaired cirriform antennae on anterior part of prostomium, extending back to end of 2nd chaetiger. Eyes absent. Peristomium fused with prostomuim dorsa lly; rudiment of peristomium formed lateral lips of mouth. Posterior lip of mouth muscular, longitudinally folded (Fig. 1, b). Nuchal grooves distinct, Parapodia biramous (Fig. 1, d; Fig. 2, a). Notopodial lobes on 1st and 2nd chaetigers small and rounded, becoming longer and cirriform on the following chaetigers. Neuropodial lobes small and tubercle-form. Modified neurochaetae appearing from posterior parapodia, with broadened stem and very long narrowed distal spine (Fig. 1, c). All the other chaetae unfringed capillaries. 3 prebranehial chaetigers. 15 pairs of branchiae.
Up to now only A. quadrilobata has trilobed prostomium in the subgenus Allia. The present specimen is slightly different from A. quadrilobata reported previously: trilobes of prostomium more conspicious, antenna only extending back to 2nd ehaetiger, notopodial lobes of prebranchial chaetigers small and rounded, branchiae unbranched. These charaetors could vary depending on the body size of individual. This is the first record of the species from China.
2. Aricidea (Allia) nolani Wester and Benedict
Many specimens collected from Qianshandao near Rezhao, Jiaochow Bay, Laoshan Nuerdao and Toudao near Qingdao. Length of complete specimens up to 6.5 mm with 65 ehaetigers, width 0.23ram not including parapodia, 0.3mm including parapodia. Prostomium triangular (Fig. 2, b). Unpaired antenna eirriform, extending back to 2nd chaetiger. Eyes not observed. Parapodia biramous (Fig. 2, c-d). Notopodial lobes on 1st and 2nd parapodia slender and cirriform, on 3rd and anterior part of branchial chaetigers longer and asymetrically enlarged basally, on the following chaetigers long and cirriform. Neu- ropodial lobes unconspicious. 3 prebranchial chaetigers. 10-11 pairs of branchiae. 2-4 modified neurochaetae from 18th-20th chaetigers, with stout stem and fine distal spine (Fig. 2, e). The other chaetae capillary. 3 anal cirri; the middle one shorter than the lateral ones.
The number of branchiae for Aricidea (Allia) nolani depends on body size of individual. The present specimens are small and only have 10-11 pairs of branchiae. This is the first record for the species from China.
3. Cirrophorus branchiatus Ehlers
One specimen from Danzidao near yantai. Length of incomplete specimen 3ram with 39 chaetigers, width 0.21mm not including chaetae. Prostomium triangular (Fig. 3, a). Unpaired antenna at posterior part of prostomium, spindle-form. Eyes absent. Peristomium fused with prostomium dorsally, parapodin biramous. Notopodial lobes on the first four parapodia small and rounded, from 5th to 10th parapodia long and cirriform, from 11th parapodia becoming short, on the last several parapodia becoming long again. 4 prebranchial chaetigers. 8 pairs of branchiae. Modified neurochaetae from 8th parapodia, with stout stem and serrated spine (Fig. 3, b). The other chaetae capillary.
4. Cirrophorus neapolitanus pacificus nov. subsp.
Holotype and paratypes have been deposited in the First Institute of Oceanography, SOA, Qingdao.
Many specimens from Jiaochow Bay, Toudao near Qingdao, Qianshandao near Rezhao, Danzidao near Yantai. Length of complete specimen up to 4.2mm with 34 chaetigers, width 0.12mm not including chaetae; the largest specimen incomplete with 68 chaetigers, length 9mm, width 0.31mm not including chaetae. Prostomium conical, without antenna(Fig. 4, a). Eyes absent. Nuchal grooves conspicious. Parapodia biramous (Fig. 4, b-c). Notopodial lobes very short on prebranchiaI chaetigers, longer on branchial chaetigers, short again on postbranchial chaetigers, much longer on posterior chaetigers. Neuropodial lobes absent. 3 prebrachial chaetigers. 11-13 pairs of branchiae, first and last pairs shorter. Notochaetae capillary and lyrate. Lyrate notochaetae from 4th or 5th parapodia, 4-5 in anterior parapodia, 1-2 in posterior parapodin. All neurochaetae capillaries. Pygidium with 3 slender anal cirri.
The new subspecies differs from the stem species C. neapolitanus mainly in the long notopodial lobes on the branchial chaetigers, absence of eyes, the shape of prostomium.
5. Tauberia gravilis (Tauber)
One specimen from Qianshandao near Rezhao. Length of incomplete specimen 1.8mm with 17 chaetigers, width 0.13mm not including chaetae. Prostomium triangular (Fig. 3, c). Terminal sensory organ at the tip of prostomium. Eyes absent. Nuchal grooves not conspicious. Parapodia biramous (Fig. 3, d). Notopodial lobes short on prebrachial chaetigers, long on the following chaetigers. 5 prebranchial chaetigers. 6 pairs of branchiae. 1-3 modified neuroehaetae from 15th parapodia (Fig. 3,c). The other chaetae capillary.
This is the first record of the species from China.
