Taxonomic Updates IOC Version 15.1 (DRAFT)

Previous Lists	English Name(s)	Updated List (v 15.1)	Code	Reference
Family Accipitridae	Kites, Hawks, Eagles		PHY	Linear sequence of taxa within Accipitridae is revised (IOC 15.1) to reflect the comprehensive phylogenetic analysis of Catanach et al. 2024.
Dryotriorchis spectabilis	Congo Serpent Eagle	Circaetus spectabilis	TAX	Restore Congo Serpent Eagle to Circaetus from Dryotriorchis to resolve the paraphyly demonstrated in Lerner & Mindell (2005) and the more recent UCE phylogenetic analysis of Catanach et al. (2024).
Trachyphonus goffinii, Trachyphonus purpuratus	Western Yellow-billed Barbet, Eastern Yellow-billed Barbet	Trachylaemus goffinii, Trachylaemus purpuratus	TAX, PHY	Move the yellow-billed barbets from Trachyphonus to Trachylaemus based on differences in habitat and plumage supported by mtDNA divergence (Dickinson & Remsen 2013; Moyle 2004; HBW/BirdLife).
Bradornis boehmi	Böhm's Flycatcher	Myopornis boehmi	TAX, PHY	Myopornis Reichenow, 1901 is resurrected as a monotypic genus for Böhm's Flycatcher which forms a sister branch to resurrected Artomyias. Together these comprise a sister clade to Bradornis in the molecular phylogeny of Muscicapini (Voelker et al. 2016). Myopornis and Artomyias are treated as separate genera based on genetic distance supported by differences in morphology, ecology and behaviour (HBW/BirdLife 2024).
Bradornis ussheri, Bradornis fuliginosus	Ussher's Flycatcher, Sooty Flycatcher	Artomyias ussheri, Artomyias fuliginosa	TAX, PHY	Artomyias Verreaux, J & Verreaux, É, 1855 is resurrected for Ussher's and Sooty Flycatchers which form a sister branch to resurrected Myopornis. Myopornis and Artomyias are treated as separate genera based on genetic distance supported by differences in morphology, ecology and behaviour. Together these comprise a sister clade to Bradornis in the molecular phylogeny of Muscicapini (Voelker et al. 2016). Aligns with HBW/BirdLife (2024). Note gender.

(2012); Catanach et al. (2024).
Strigops habroptila	Kakapo	Strigops habroptilus	TAX	Change the specific epithet of Kakapo from the adjectival form habroptila to the noun form habroptilus. The specific epithet is a compound noun, not an adjective as previously surmised (Savage & Digby. 2023. Bulletin of Zoological Nomenclature 80).
Philydor fuscipenne, Philydor erythrocercum	Slaty-winged Foliage-gleaner, Rufous-rumped Foliage-gleaner	Neophilydor fuscipenne, Neophilydor erythrocercum	TAX, PHY	Gen. nov.: Neophilydor Sangster, Harvey, Gaudin & Claramunt, 2023. Neophilydor is described to resolve the polyphyly of Philydor that is demonstrated in phylogenetic analyses (Derryberry et al. 2011; Harvey et al. 2020; SACC 991).
Phyllomyias burmeisteri, Phyllomyias zeledoni	Rough-legged Tyrannulet, White-fronted Tyrannulet	Acrochordopus burmeisteri, Acrochordopus zeledoni	TAX	Acrochordopus is resurrected for two species formerly included in Phyllomyias but which differ from that genus by deep genetic divergence, morphology, and by vocalizations (Harvey et al 2020; SACC 962; Chesser et al. 2024).

Lophorina	Lophorinas		TAX	Restore the tradiional classficaton of the species within Lophorina following Elliott et al. (2020, 2022) who argue that the neotypification of Irestedt et al. (2017), formerly followed, is neither required nor justified and, as such, the revised nomenclature of the Lophorina complex should be rejected in favour of traditional usage (WGAC 876).
Lophorina superba latipennis	Greater Lophorina	Lophorina latipennis	TAX	Restore Lophorina latipennis as a full species with the restoration of the more traditional classfication of the genus Lophorina.
Poecilodryas brachyura	Black-chinned Robin	Leucophantes brachyurus	TAX, PHY	Move Black-chinned Robin from Poecilodryas to the resurrected genus Leucophantes based on unpublished mtDNA analysis by L Raty used on Genbank material deposited by KA Jønsson in 2022 which reveals that Black-chinned Robin is deeply divergent from the other members of the Poecilodryas clade (WGAC 1094),
Mirafra rufa	Rusty Bush Lark	Calendulauda rufa	TAX	Move Rusty Bush Lark from Mirafra to Calendulauda based on vocalizations, structure, plumage and genetics (Alström et al. 2023).

Elseyornis melanops	Black-fronted Dotterel	Charadrius melanops	TAX, PHY	Black-fronted Dotterel was previously assigned to the monotypic genus Elseyornis. But phylogenetic analyses show it to be sister to the two species formerly assigned to Thinornis, Hooded Plover and Shore Plover, which are now included in Charadrius (Barth et al. 2013; Černý & Natale 2022).
Thinornis cucullatus, Thinornis novaeseelandiae	Hooded Dotterel, Shore Dotterel (now Hooded Plover, Shore Plover)	Charadrius cucullatus, Charadrius novaeseelandiae	TAX, PHY	Hooded Dotterel and Shore Dotterel (now Hooded Plover and Shore Plover), formerly included in the genus Thinornis, are embedded in Charadrius in phylogenetic analysis (dos Remedios et al. 2015).
23 species in the genus Charadrius	Caspian Plover, Oriental Plover, Greater Sand Plover, Siberian Sand Plover, Tibetan Sand Plover, New Zealand Plover, Wilson's Plover, Collared Plover, Mountain Plover, Puna Plover, Two-banded Plover, Madagascar Plover, St. Helena Plover, Kittlitz's Plover, Red-capped Plover, Snowy Plover, Chestnut-banded Plover, Malaysian Plover, White-fronted Plover, Kentish Plover, White-faced Plover, Javan Plover, Double-banded Plover.	Genus Anarhynchus	TAX, PHY	Anarhynchus was formerly a monotypic genus associated with Wrybill Anarhynchus frontalis. But phylogenetic analysis reveals that, despite its unique bill, it is deeply embedded in a large clade of plovers classically attributed to Charadrius but significantly divergent from that genus (dos Remedios et al. 2015; Eaton et al. 2021). Anarhynchus is the oldest available name for this clade (Eaton et al. 2021; WGAC 882).
Family Jacanidae	Jacanas		PHY, SEQ	The linear sequence of genera and species within Jacanidae is revised based on phylogenetic analysis (Černý and Natale 2022).

Family Fregatidae	Frigatebirds		PHY, SEQ	The linear sequence of species within Fregatidae is revised based on Martins et al. (2022).
Family Sulidae	Gannets, Boobies		PHY, SEQ	The linear sequence of genera and species within Sulidae is based on the phylogeny in Patterson et al. (2011).
Family Ardeidae	Herons, Bitterns		PHY, SEQ	Revise linear sequence of genera and species in Ardeidae based on Hruska et al. (2023).
Gorsachius leuconotus	White-backed Night Heron	Calherodius leuconotus	TAX	Move White-backed Night Heron from Gorsachius to the monotypic genus Calherodius based on phylogenetic analysis which demonstrates that it forms a clade deeply divergent from the two species in Gorsachius proper (Hruska et al. 2023; HBW/Birdlife).
Gorsachius magnificus	White-eared Night Heron	Oroanassa magnifica	TAX	Move White-eared Night Heron from Gorsachius to the monotypic genus Oroanassa based on phylogenetic analysis which demonstrates that it forms a clade with Calherodius which is deeply divergent from the two species in Gorsachius proper (Hruska et al. 2023; HBW/Birdlife). Although Calherodius and Oroanassa are sister taxa, and share a clade, they are deeply divergent which supports a two genus treatment. Note change in gender.
Family Trogonidae	Trogons		PHY, SEQ	Revise the linear sequence of genera within Trogoniformes following the phylogeny of Oliveros et al. (2018).
Family Lybiidae	African Barbets		PHY, SEQ	Sequence genera is revised to more closely align with other major world bird lists based on Moyle (2004).
Stactolaema olivacea	Green Barbet	Cryptolybia olivacea	PHY, TAX	The monotypic genus Cryptolybia is resurrected for Green Barbet which was formerly assigned to Stactolaema but which is paraphyletic in regards to that genus in phylogenetic analysis (Moyle 2004).

These five larger species uniquely share similarities in morphology, voice and sexual dimorphism that separate them from the smaller members of Lybius. They are treated as a subgeneric group of Lybius by Short and Horne (1985). This treatment is further supported by the phylogenetic analysis of Moyle (2004) which, despite its incomplete taxon sampling, illustrates Lybius s.l. to consist of two sister clades which correspond to the subgeneric groups of Short and Horne (1985).
Reinwardtipicus validus	Orange-backed Woodpecker	Chrysocolaptes validus	TAX	Move Orange-backed Woodpecker from the monotypic genus Reinwardtipicus to Chrysocolaptes (Eaton et al. 2021; HBW/BirdLife). Though moderately diverged genetically and morphologically (Benz et al. 2006, Fuchs et al. 2017) vocalizations are similar and the plumage is consistent with a basal taxon within the broader genus (WGAC 797).
Family Cacatuidae	Cockatoos		PHY, SEQ	The genera and species of Cacatuidae are resequenced following the phylogeny of Smith et al. (2023).
Phylloscartes paulista	Sao Paulo (Tyrannulet) Bristle Tyrant	Pogonotriccus paulista	PHY, TAX	Phylogenetic data reveal that Phylloscartes paulista is embedded within Pogonotriccus (Harvey et al. 2020). Move species to Pogonotriccus (SACC 959).
Phylloscartes difficilis	Serra do Mar (Tyrannulet) Bristle Tyrant	Pogonotriccus difficilis	PHY, TAX	Phylogenetic data reveal that Phylloscartes difficilis is embedded within Pogonotriccus (Harvey et al. 2020). Move species to Pogonotriccus (SACC 959).
Antilophia bokermanni, Antilophia galeata	Araripe Manakin, Helmeted Manakin	Chiroxiphia bokermanni, Chiroxiphia galeata	PHY, TAX	Phylogenetic analyses reveal that despite morphological differences, Antilophia is embedded in Chiroxiphia. Move Araripe Manakin and Helmeted Manakin from Antilophia to Chiroxiphia with the merger of the genera (Silva et al. 2018; Harvey et al. 2020; Leite et al. 2021; SACC 975).
Family Acanthizidae	Australasian Warblers		PHY, SEQ	Revise the sequence of genera and species within Acanthizidae following Clements (2023) based on the work of E. Miller (unpub. data) which synthesizes the phylogenies in Selvatti et al. (2015), Marki et al. (2017), Norman et al. (2018) and Fjeldså et al. (2020).
Hemixos leucogrammicus	Cream-striped Bulbul	Ixos leucogrammicus	TAX	Cream-striped Bulbul was previously tentatively placed in Hemixos with reservations (Shakya & Sheldon 2017). But because this species is a deep lineage without close relatives, it is tentatively moved to Ixos based on some similarities in plumage with other species in that genus, essentially as a placeholder, following WGAC 761.
Family Hirundinidae	Swallows, Martins		PHY, TAX	The linear sequence of genera and species within Hirundinidae is modified to better align with Clements (2023) and the phylogeny of Brown (2019).
Petrochelidon fuliginosa	Forest Swallow	Atronanus fuliginosus	PHY, TAX	Forest Swallow was formerly placed in Petrochelidon as P. fuliginosa. However, a new monotypic genus proposed for it: Atronanus de Silva et al., 2018, is tentatively adopted here to align with BirdLife and Clements (2023) but the new genus lacks Zoobank registration. Note gender.

(Mindell et al. 2018).
Lophochroa leadbeateri	Major Mitchell's Cockatoo	Cacatua leadbeateri	TAX, PHY	Restore Major Mitchell's Cockatoo to Cacatua from Lophochroa (Schodde & Mason 1997; HBW/BirdLife). The species is deeply basal within the same clade as the other species in Cacatua (Provost et al. 2018). But it shares similar morphological, behavioral, and vocal features as the other species in that genus, suggesting that Lophochroa may be more appropriately treated as a subgenus.
Thripophaga berlepschi	Russet-mantled Softtail	Cranioleuca berlepschi	TAX, PHY	Phylogenetic analysis shows that Russet-mantled Softtail does not belong in Thripophaga but rather it is sister to the two Cranioleuca species Marcapata and Light-crowned Spinetails. Move from Thripophaga to Cranioleuca (Derryberry et al. 2011; Harvey et al. 2020).
Cranioleuca gutturata	Speckled Spinetail	Thripophaga gutturata	TAX, PHY	Phylogenetic analysis shows that Speckled Spinetail does not belong in Cranioleuca but rather it is a basal taxon within the Thripophaga clade (Derryberry et al. 2011; Harvey et al. 2020). Move from Cranioleuca to Thripophaga.

Cossypha isabellae	Mountain Robin-Chat	Cossyphicula isabellae	TAX, PHY	Reassign Mountain Robin-Chat from Cossypha to Cossyphicula based on phylogenetic analysis which shows it sister to Cossyphicula roberti (Zhao M et al. 2023). See also Beresford (2003).
Cossypha humeralis, Cossypha caffra, Cossypha archeri, Cossypha anomala	White-throated Robin-Chat, Cape Robin-Chat, Archer's Ground Robin, Olive-flanked Ground Robin	Dessonornis humeralis, Dessonornis caffer, Dessonornis archeri, Dessonornis anomalus	TAX, PHY	The resurrected genus Dessonornis is applied to four species formerly assigned to Cossypha but which form a distinctly separate clade in phylogenetic analyses (Beresford 2003; Zhao M et al. 2023). As noted by Mayr & Paynter (1964) and others, Dessonornis (Smith, A, 1836) is a misspelling, later corrected by the author himself to Bessonornis (Smith, A, 1844). However, it is not clear that Smith's later emendation satisfies ICZN Art. 32.5.1.1. Use of Dessonornis follows Wolters (1975). Treatment of Dessonornis as masculine follows HBW/BLI and ICZN 30.2.4 .
Rhodothraupis celaeno	Crimson-collared Grosbeak	Periporphyrus celaeno	TAX	Move Crimson-collared Grosbeak from the monotypic genus Rhodothraupis to Periporphyrus based on genomic data which shows that this species is closely related to Red-and-black Grosbeak P. erythromelas (Bocalini et al. 2021; Chesser et al. 2023).

Polihierax insignis	White-rumped Falcon	Neohierax insignis	TAX	Phylogenetic analysis of Falconidae reveals that White-rumped Falcon is not sister to Pygmy Falcon Polihierax semitorquatus. Rather it is a basal taxon in the same clade as Falco while Pygmy Falcon is sister to Microhierax which together form a separate clade. Resurrect the monotypic genus Neohierax for White-rumped Falcon to preserve monophyly (Fuchs et al. 2015).
Phaeomyias murina, Phaeomyias tumbezana	Mouse-colored Tyrannulet, Tumbesian Tyrannulet	Nesotriccus murinus, Nesotriccus tumbezanus	TAX, PHY	Phylogenetic analysis reveals that Cocos Flycatcher (Nesotriccus) is embedded in the Mouse-colored Tyrannulet radiation (Phaeomyias). Since Nesotriccus has priority over Phaeomyias, the former genus prevails for the merged genus (Zucker et al. 2016). Note that Phaeomyias is feminine but Nesotriccus is masculine. Species-group epithets are modified accordingly.
Poeoptera sharpii	Sharpe's Starling	Pholia sharpii	TAX, PHY	Restore Sharpe's Starling to the monotypic genus Pholia from Poeoptera (Clements 2022; WGAC 2022).

Reassign to monotypic Radinopsyche gen. nov. Whitney, Bravo, Belmonte-Lopes, Bornschein, Pie & Brumfield, 2021 (Bravo et al. 2021; SACC 915). Resequence.
Sakesphorus cristatus	Silvery-cheeked Antshrike	Sakesphoroides cristatus	TAX, PHY	Phylogenetic analysis reveals that Silvery-cheeked Antshrike is not closely related to the other two species in Sakesphorus but rather is sister to a clade formed by Herpsilochmus + Dysithamnus. Move to the resurrected genus Sakesphoroides Grantsau 2010 based on genetic and morphological differences. (Bravo et al. 2021; SACC 914).
Lichmera lombokia	Scaly-crowned Honeyeater	Sugomel lombokius	TAX, PHY	Phylogenetic analysis demonstrates that Scaly-crowned Honeyeater is sister to Black Honeyeater rather than to other species in the genus Lichmera to which is was formerly assigned (Marki et al. 2017).
