Etymology: Eviota: No etymology given, suggested by Christopher Scharpt: from Latin 'eu' for 'true' and 'iota' for anything very small, in combination 'truly very small' referring to it as being the smallest vertebrate at the time it has benn described by Jenkins (thus, making the suggestion by Scharpt plausible.; epistigmata: Name from Greek combination of 'epi' meaning over, and 'stigmata', meaning spot or mark, referring to the dark mark on the upper portion of the caudal peduncle..

Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 7; членистые (мягкие) лучи спинного плавника (общее число) : 8; колючие лучи анального плавника: 1; членистые (мягкие) лучи анального плавника: 7 - 8; позвонки: 26. This species is distinguished by the following characters: fifth pelvic-fin ray absent or rudimentary; dorsal to anal fin-ray formula 8/8; 5 or fewer dark internal spots or bands between anal-fin origin and caudal fin; no distinct markings on pectoral-fin base; similar with E. nigramembrana, it has a small, dark occipital spot; differs from E. nigramembrana by not having an obvious area of dark pigment on the opercular membrane; edges of the scale pockets are more heavily pigmented than E. nigramembrana; has a dark internal mark above the midline of the ural centrum (vs. on the middle of the centrum in E. nigripinna and over the entire centrum in E. winterbottomi); dorsal fin dark dusky basally and marginally, pale or light dusky in central portion of fin (Ref. 96083).
