Nat. Hung., Ann. 12 : 306 , 1914 . This genus is distinguished from Tethina and related genera by the possession of outstanding though not very long bristles on the anterodorsal and posterodorsal surfaces of the mid and hind tibiae. There is an Australian subgenus of Tethina that has similar tibial bristles, but in it the postvertical bristles are undeveloped while in the present genus they are strong.
