Dinematichthyini
Dinematichthyini is a tribe of viviparous brotulas, which is conventionally placed within the subfamily Brosmophycinae. They are differentiated from the other tribe  within that subfamily, the Brosmophycinae , by having a single pair of ossified genital claspers, having an absence or greatly reduced scales on the head and having the posterior end of the maxillary bone showing a small amount of vertical expansion. A review of the viviparous brotulas carried out in 2016 elevated the tribe to a family, the Dinematichthyidae.
