For Vyshkvartzeva (2001, p.92) notes that Bradford & al. (1983, p.91) considered that this species is not really a scolecithrid. As reexamination has shown, the species has the typical of the family Scolecitrichidae composition of Mx2 endopod sensory setae (3 worm-like and 5 brush-like setae. Mxp with 1 brush-like sensory seta in the middle of syncoxa of the species dealt with here is typical of many Scolecitrichidae genera and is not reported in other Bradfordian families
