Diagnosis Test significantly expanded laterally (alate, sensu Mooi et al., 2000), much more so than in any other species of Protoscutella. Test width increases significantly in proportion to the test length as the specimens increase in size so that the test has a distinct triangular shape as the test widens through the posterior paired interambulacra. Periproct conspicuously supramarginal in both small and large specimens. First plates to contact the periproct moving distally from the peristome are the a7 and b7 plates, as identified using the Lovénian system (Lovén, 1874). [details]
