The front of the head is bordered by a blue line; the dorsum bears an interrupted blue stripe along each side; the upper side of the foot is edged with a similar blue marginal stripe; a median blue line runs along the dorsum of the tail and appears to form a loop posteriorly. The gill plumes are bluish-green with somewhat blackish lateral pinnae.Distribution

The specific epithet morosa is the feminine of Latin morosus ("morose, sullen, gloomy"), referring to the very dark, sombre colour of the living animal — captured at the head of the Latin diagnosis: "Color animalis vivi aterrimus" ("the colour of the living animal is very black").Remarks
Preyed upon by Roboastra luteolineata. Tambja kushimotoensis is recognised as a junior synonym.References
