Original Description Test of medium size, low trochospire; peripheral margin circular, lobate; seven to eight chambers in the last whorl arranged in an alternation of lower and higher planes, increasing gradually in size as added; chambers petalloid on spiral side, subtriangular on umbilical side; ovoid in apertural view; primary aperture extraumbilical-spiroumbilical in position; umbilicus shallow. Size: Etymology: This species is named for Maria Clara Flores de Hernandez in honor of her many years of working with the foraminiferal faunas of Mexico Extra details from original publication Variation of the species. Ticinella floresae n. sp. displays little morphologic variation. It is one of the most diagnostic species of Ticinella, and is abundant in the material studied. More than eighty specimens were observed, and all show a low trochospiral coil. The number of chambers in the last whorl varies from seven to eight; however, specimens with seven chambers in the last whorl are more common.
Remarks. Ticinella floresae n. sp. differs from T. primula Luterbacher and T. aperta Sigal by it diagnostic ultimate whorl with chambers arranged in an alternation of lower and higher planes, where one chamber is up and the next is down.
Range. Ticinella primula Zone (lower Albian) to T. breggiensis Zone (upper Albian) . Editors' Notes
