Comments.

Described by Lesson as originating from ‘Nouvelle-Hollande’ or Australia, with Péron as its origin; the number of specimens is not cited. They were the only two specimens in the MNHN until another specimen from Tasmania arrived from Maison Verreaux in 1844. It is identified in the Parisian catalogue (MNHN Laboratory, ZMO-GalOis 1) as Collared Sparrowhawk Accipiter cirrocephalus (Vieillot 1817). However, both syntypes are in fact Brown Goshawks Accipiter fasciatus (Vigors and Horsfield 1827) (contra Voisin and Voisin 2001: 184-185), and are misidentifications and therefore corrected (article 67.13 (ICZN 1999)). Their identification as A. fasciatus is based on the rounded tip of the tail and the position of the 1st knuckle on the outer and middle toes, which are longer than Accipiter cirrocephalus ( Menkhorst et al. 2017). These specimens are also syntypes of Falco torquatus (Cuvier 1821), and Accipiter fasciatus hellmayri (Stresemann 1953). The type locality is erroneous (Nouvelle-Hollande), and therefore corrected and restricted to: West-Timor, near Kupang Bay (article 76a.2.A (ICZN 1999)). Lesson named this species Glareola australis or ‘southern’ ( Jobling 2017).
