Original Description

Test medium size, longer than broad, early part very low trochospiral (very much like Globigerina triloculinoides Plummer), last chamber completely spherical, comprising about 50 to 60 percent of test, 3 chambers visible on umbilical side; sutures depressed in spiral part strongly incised around final chamber and remainder of test; wall finely pitted, pitting somewhat more pronounced in early portion; aperture inclined, extending from umbilicus toward periphery, with very distinct lip, accessory openings not observed.

Length, 0.50-0.40 mm.; breadth, 0.18-0.30 mm.

Extra details from original publication

Remarks. - Globigerina dudrouensis resembles Globigerinoides triloba triloba (Reuss) [Globigerina triloba 1850] but, unlike that form, it has no semicircular aperture. Moreover, the opening is covered by a distinct lip, which extends from the umbilicus toward the periphery of the test. The position of the aperture and the general shape, especially of the final chamber, separate the species from Globigerina triloculinoides.
