Sinochonetes wangi Racheboeuf, 1987   ( Fig. 8 View FIG )

Sinochonetes wangi Racheboeuf, 1987: 11   , pl. 3, figs 15-21.

MATERIAL EXAMINED. — Shells embedded in the coquina from loc. 21581, Krasnaya Bay, Komsomolets Island ( Männik et al. 2002: fig. 1); Severnaya Zemlya or Pod”emnaya formations.

REMARKS

The dimensions of the shells vary from 6.5 to 9.6 mm in length and from 10.0 to 14.0 mm in width; the average L/W ratio is 0.63. Anderidia diverges anteriorly and fuses with cardinalia posteriorly at 60°. Cardinal process is internally bilobed with additional, poorly developed lateral lobes, and is posteriorly closed by chilidium. The external and internal morphology of both valves are typical of the genus Sinochonetes   , and our specimens are morphologically identical with S. wangi   described from the lower Emsian(?) strata of Ellesmere Island (Canadian Arctic). S. wangi   differs from the type species, S. minutisulcatus Hou & Xian, 1975   (Siegenian of South China, Hou & Xian 1975: 25, pl. 1, figs 3, 4), in having finer costellae (7-10 per 1 mm), more numerous spines (five), and a poorly developed ventral sinus.
