«Genus Merklinia SOBETZKI, 1960
Type species: Pecten asper LAMARCK, 1819 (O. D.).
Emended diagnosis (1): Acline, rounded-triangular to almost orbicular, equilateral shells; the umbo is straight; the apical angle varies from approximately 75°, on small specimens, to 1200, on large ones; the auricles are relatively small : the anterior auricle of the right valve has abyssal sinus that is relatively shallower on large than on small specimens; the other auricles are almost right-angled and subequal; the macrosculpture consists of well developed spine-bearing ribs (10 to 20) which are subdivided into a varying number of side-riblets: extreme subdivision of the ribs near the pallial margins results in an intricate structure of lobes of various degrees at this margin; lunulate areas are present at both sides of the umbo; they are covered with fine striae (pI. II, fig. 2B).
SOBETZKI considered Merklinia as a subgenus of Chlamys (1960, p. 67).» (1) The original diagnosis by SOBETZKI is a description of the type-species and is not applicable to any other species included in the genus by that author.
