A, B: Spelaeogriphus lepidops, (Spelaeogriphacea) exhibits an eyeless rudimentary eyestalk (A), a slender antenna 1 and a prominent antenna 2 (dark hue of specimen in A due to artificial staining). B: Courtesy by G. Giribet. C: Mictocaris halope (Mictocarididae) exhibits an eyeless rudimentary eyestalk, and a prominent antenna 1 and 2. D, E: Confocal micrographs of cuticular autofluorescence. In contrast to the other species, the antenna 1 of Tethysbaena argentarii is more prominent than the slender antenna 2. An eyestalk is absent. Scale bars: 0.5 mm.
