Original Description
"Test minute, about equally biconvex, periphery acute but not keeled, umbilicus open; chambers indistinct, 5 or 6 in last-formed whorl, gradually increasing in size as added, flat on the dorsal side but distinctly inflated ventrally; sutures curved but indistinct on the dorsal side, radial and distinctly incised on the ventral side; wall thin, finely perforate, finely granular; aperture a low opening under the edge of the last-formed chamber, protected by a projecting lip.

Size: Length 0.17-0.20 mm.; breadth 0.15-0.17 mm.; thickness 0.10 mm.

Etymology: from Cap-devila formation

Extra details from original publication
This small species occurs frequently in numerous samples in the lower Eocene, Capdevila formation, where it is a good index fossil although easily overlooked because of its very small size. It differs from G. fohsi Cushman and Ellisor in its much smaller size, less inflated test, fewer chambers, and more distinct sutures on the ventral side.

It is a fine technical point, and I don't think it actually matters much. Both combinations Globorotalia capdevilensis and Globorotalia (Globorotalia) capdevilensis are validly available. The authors probably should have used Globorotalia (Globorotalia) capdevilensis but did use Globorotalia capdevilensis - and possibly in 1949 the rules were less clear. I generally try in the catalog to stay as close as possible to what the authors published, so my preference is to record their actual use here.

As with G. albeari it was actually published as G. capdevilensis, although I suspect you are correct that even at the time of publication the technically correct citation would have been G. (G.) capdevilensis
