Original Description

Gorbachikella depressa differs from G. kugleri in having a more depressed periphery of each chamber, a very low symmetrical axiointraumbilical aperture with a very weak rim, and a higher spire. The aperture is similar to the Conoglobigerina- type aperture, but the surface of the test is smooth and microperforate (see Pl. 3 , fig. 3b, 4b).

Extra details from original publication
G. depressa ranges in Tunisia throughout the Hauterivian and Barremian.

Hello,

In the authority, the last name is Gorbachik not Gorbachil.

Same as for Gorbachikella grandiapertura

They also described Gorbachikella anteroapertura in the same paper.

Best,

thanks, I've corrected that, and added the missing species
