Solem included six species in his original circumscription: V. eniwetokensis, V. kondoi, V. nayauana, V. niueana, V. tongensis, and V. vaitupuensis.

[5] A review of Solem's monograph published in Systematic Biology noted his propensity for "creative generic nomenclature" which "may either lighten the reader's day or engender hostility" and alluded to this genus as one of its examples.

[7] Solem notes that Vatusila species can have "rather widely different appearance of the sculpture and large size range".

[7] The holotype and only specimen of V. eniwetokensis dates to the Upper Miocene,[2] V. nayauana and V. kondoi are both critically endangered according to the IUCN Red List.

They both live in forests on Nayau and their habitat is affected by increased wood harvesting.
