Mitromorpha mirim is a species of sea snail, a marine gastropod mollusk in the family Mitromorphidae. [1]
The shell reaches a length of up to 3.7 mm and is fusiform in outline, with the width approximately half the shell length. Shell colour is uniformly pale beige, with a whitish band near the suture. The protoconch is paucispiral (spiral with few turns), consisting of about 1.5 smooth, glossy whorls and forming roughly 10% of the total shell length. [2]
The teleoconch comprises about four whorls and is sculptured with spiral cords and axial undulations, producing a weak reticulate pattern. The subsutural cord is slightly larger and more nodulose than the remaining sculpture. The aperture is elongated, accounting for about 60% of the shell length. The outer lip is internally lirate, bearing four to five weak spiral cords, while the inner lip shows a pair of low columellar folds. The siphonal canal is short and slightly projected forward. [2]
This marine species occurs off Espírito Santo, Brazil, on the continental slope of the Abrolhos region. [2]
The species inhabits sandy-mud bottoms at depths between 60 and 105 m (197 and 345 ft). [2]
The specific name mirim is derived from the Tupi–Guarani word meaning “small”, referring to the small size of the shell. [2]
