Commentary on the genus names Microspizias and Parabuteo.
by Mathew Louis
SUMMARY The genus Microspizias was proposed for species-level taxa to rectify the matter of assignment of them as being separate from the genus Accipiter. The authors explained that only through Kaup's 1845 reference to the genus name Hieraspiza can typification of the latter be allowed, which they designated to Falco virgatus Temminck. Microspizias was proposed with an additional appendix listing the generic synonyms of Accipiter, but these included omissions. One of them, Teraspiza Kaup, has had a separate treatment in the literature from Hieraspiza. I have interpreted the nomenclatural rules to allow for an assignment of availability to Teraspiza, due to it being neither an emendation nor a permanent, incorrect subsequent spelling. Also treated is the correct attribution of dates of two important works relating to the typification of this name. However Teraspiza was proposed as an incorrect subsequent spelling of Hieraspiza, Newton (1868) was the first author to give it availability. Sharpe in Catalogue of the Birds in the British Museum was published later than Ridgway in History of the Birds of North America. Wetmore’s evaluation of Ridgway allows for a more precise and earlier date of publication for said work. Ridgway's typification of Teraspiza to Falco tinus [=Falco superciliosus] has priority, and it is explained that Microspizias is a junior synonym. A difficulty relating to the genus name Parabuteo is given exposition and discussed, with an explanation as to why its priority over the genus name Erythrocnema should be retained.
The genus name Microspizias Sangster et al. (2021) was proposed for taxa which had been previously noted to be distinct from Accipiter Brisson, 1760 (Olson 2006; Mindell et al. 2018). Recent studies on the phylogenetic relationships of these particular taxa show them to not be closely related to Accipiter (Mindell et al. 2018).
Sangster et al. designated Falco superciliosus Linnaeus, 1766 as the type of Microspizias. The new name Microspizias was created to address a nomenclatural problem relating to another name associated with these taxa, Hieraspiza Kaup, 1845. Kaup (1844), in first publishing Hieraspiza, had employed wording which did not allow for it to be a concept other than a nomen nudum With Hieraspiza again employed (Kaup 1845), the names Falco virgatus Temminck, 1822 and Falco Dussumieri Temminck, 1824 were included in it. Sangster et al. (2021) typified Hieraspiza to Falco virgatus, though earlier authors had designated this species to Kaup (1844). For all other species names associated with Hieraspiza other than the two cited above, typification is not permissible per Article 67.2 of the Code (ICZN 1999). This exclusion likewise applies to the name Falco superciliosus Linnaeus, 1766 (=Falco tinus Latham, 1790).
In Sangster et al. there is a synonymy of Accipiter (Appendix 1). My attention was drawn to outstanding names not cited therein, including Teraspiza Kaup (1867) .
