Diagnosis
ReferenceDiagnosis
A. Williams 1962Small, unequally biconvex Paucicrura with a slightly shallower brachial valve beating a sharp, deep, median sulcus; outline subcircular and closely comparable with P. sila; ornamentation costellate and like that of P. sila except that costa 1 is median, situated within the cleft of the sulcus and without external secondaries at the 2-mm. growth-stage; internal morphology similar to that of P. sila except for a rather smaller dorsal adductor scar averaging slightly more than one-third the length of the brachial valve.
