Aggregate form with anterior end of body rounded, the posterior end is somewhat fusiform. The test is bluntly pentagonal and never echinate. M1-M3 and M4-M5 are fused mid-dorsally; both groups of muscle bands are separated in lateral view. The nucleus has a posterior projection. The test is pentagonal posteriorly. The number of muscle fibres in M1-M5 is 15-17, normally 16. The atrial opening is not central and there is a posterior lateral protuberance on one side only. Solitary form with smooth test, atrial palps simple and straight; lateralprojections small, medioventral projections are small and of unequal length, the anterior ones are the smallest. All test projections are echinate. M1-M4 are continuous dorsally and ventrally; M5 is narrowly interupted ventrally. M2-M4 and M5-M6 are converged mid-dorsally over a short distance only. The stomach partly extends into the middle posterior projection.
