There is variation in petal length among the studied specimens. Some specimens (WUSL/EI/38 and EI/48) have equally sized anterior and posterior petals while WUSL/EI/143 has longer posterior petals compared to petal III. WUSL/EI/41 and EI/52 have greater test edge thickness relative to test height. A few specimens (WUSL/EI/50, EI/51, and EI/53) collected from the same locality have an unusually pointed anterior end. In addition, these specimens have a higher test edge thickness and apical system situated 51–52% TL from anterior margin (
