Abstract
The New Zealand asaphid trilobite Ogygites collingwoodensis is redescribed on the basis of the type material and new collections, and its assignment to Basiliella is confirmed. The species occurs with the trinucleid trilobite Incaia bishopi and graptolites indicative of the Nemagraptus gracilis zone (early Late Ordovician, early Sandbian/Gisbornian), mostly as disarticulated material in intensely bioturbated siltstone of the Douglas Formation. Comparison with coeval faunas is limited due to the low diversity of this fauna, but B. collingwoodensis shows some limited similarity to contemporaneous eastern Australian faunas, whereas Incaia also occurs in South America and South China.
