The genus is divided into two subgenera Lolliguncula and Loliolopsis.
They are rather small squids with a maximum mantle length of 120mm,[2] that inhabit shallow warm seas, although some species have been recorded in areas of low salinity.
The males produce spermatophores with a long cement body and they lack a ventral crest on their hectocotylus.
Their suckers have square teeth which ring the entire margin or are placed distally.
The males do not have enlarged suckers on the left ventral arm.
