Current identification/main database link: Igorina tadjikistanensis (Bykova 1953)
[Basically, this species differs in the marked inflation of its test and in having a larger number of chambers than closely related Globorotalias such as Globorotalia pseudoscitula Glaessner and Globorotalia planoconica Subbotina. Specimens are often found with as many as seven chambers in the final whorl, but the final chamber is always bulla-like, with a markedly thinner and smoother wall, and is always smaller than the penultimate chamber.]
