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. Genera The following genera are included in the tribe Dinematichthyini: Alionematichthys Beaglichthys Brosmolus Brotulinella Dactylosurculus Dermatopsis Dermatopsoides Diancistrus Didymothallus Dinematichthys Dipulus Gunterichthys Lapitaichthys Majungaichthys Mascarenichthys Monothrix Nielsenichthys Ogilbia Ogilbichthys Paradiancistrus Porocephalichthys Typhliasina Ungusurculus Zephyrichthys References Bythitidae Viviparous fish Fish tribes
