This new genus has an agglutinated test wall, slightly asymmetrical test, short internal longitudinal partitions, and an asymmetrical interiomarginal aperture. Three species are described, Q. breviseptum sp. nov., Q. compressa sp. nov. and Q. inflata sp. nov., separated on the number of the chambers In the outer whorl and on the maximum diameter/thickness ratio. A new species of the genus Thalmannammina, T. anfracta, is also described.
