Fig. 4 View FIGURE 4 A, B
Cypridina tonkinensis Patte 1926:128 , pl. VIII: figs. 28–30; pl. IX, fig. 1.
Holotype
None selected.
Type locality
Khau Phai Shales, North Vietnam.
Material
No material examined herein.
Distribution
Khau Phai Shales, North Vietnam, Triassic.
Diagnosis
Oval in lateral view. Rostrum well developed, forming right angle with edge of valve ventral to rostrum, or slightly overhang incisure. Central adductor muscle scars with four oblique scars and additional scars.
Comparisons
Differs from M. hollandica in central adductor muscle scar pattern.
Remarks
Bless (1973:248) stated that this Triassic species may belong in his new genus Radiicypridina collected in the Upper Carboniferous, but the description by Patte (1926) did not permit a definite conclusion. The species is referred to Triadocypris herein, because its shape more closely resembles other species referred to that genus, and valves are without an indented incisure and caudal process generally present on species of Cypridina . The central adductor muscle scars are visible on illustrated specimens but are difficult to decipher.
