Named by Carter.

Original description: Cortical shell generally subtriangular, somewhat &64258;uted and irregular in outline with convex upper and lower surfaces and three medium-sized, strongly tapering spines. Surface of shell double layered; inner layer of pore frames variably-sized and irregular in shape. Outer layer of pore frames extremely variable in size (some quite enormous), irregular in shape; outer layer of pore frames with very large raised nodes some coalescing to form strong raised ridges. Pores subequal in size, irregular in shape. Primary spines equally distributed around shell; spines composed of very narrow ridges and wide deep grooves.

Original remarks: Charlottea penderi differs from Charlottea hotaoensis n. sp. in having an irregularly-shaped cortical shell with more convex surfaces, large raised nodes some forming ridges, and primary spines are more equally distributed around shell.

Etymology: This species is named after Captain Pender who originally named Maude Island during the 1866 survey.

Charlottea penderi was named by Gorican et al. (2006). Its type specimen is GSC 111715 and is a 3D body fossil. Its type locality is Maude Island, west of Ells Bay; GSC loc. C-304566, which is in a Pliensbachian marine limestone in the Fannin Formation of Canada.
