Protozoa - Entactinaria - Eptingiidae

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.
