Body length of females up to 8.0 mm, of males up to 6.0 mm or slightly more. Head without rostrum. Eyes absent. Antennae 1 relatively short; in female slightly shorter than head and first pereonite combined, slightly longer and larger in male. Antennae 2 slightly shorter than A1 with enlarged antennal gland.

Pereopod 5 subchelate with dactylus closing against distally broadened propodus; remaining pereopods simple. Monospecific. Sexual dimorphism. As for Microphasma . Remarks.
