Cocos Tyrannulet Nesotriccus ridgwayi is embedded within the genus Phaeomyias (Zucker et al. 2016, Harvey et al. 2020); as Nesotriccus Townsend 1895 has priority over Phaeomyias Berlepsch 1902, Phaemomyias is considered to be a junior synonym of Nesotriccus. The presence of Cocos Tyrannulet within Mouse-colored Tyrannulet thus makes the latter to be paraphyletic; furthermore, the vocalizations of several taxa previously considered to be subspecies of Mouse-colored Tyrannulet are rather different (Ridgely and Greenfield 2001, Schulenberg et al. 2007, Boesman 2016j). Therefore Mouse-colored Tyrannulet is split into four species: the polytypic group Mouse-colored Tyrannulet (Tumbes) Phaeomyias murina tumbezana/inflava becomes Tumbes Tyrannulet Nesotriccus tumbezana, with subspecies tumbezana and inflava (Because the name Nesotriccus is masculine, while Phaeomyias is feminine, the correct formulations are Nesotriccus tumbezanus, with subspecies inflavus; we became aware of this mistake too late to correct in the eBird/Clements spreadsheet, but we will revise the name accordingly in our 2023 release; the monotypic group Mouse-colored Tyrannulet (Marañon) Phaeomyias murina maranonica becomes Marañon Tyrannulet Nesotriccus maranonica (for which the correct formulation is Nesotriccus maranonicus); the polytypic group Mouse-colored Tyrannulet (Northern) Phaeomyias murina incomta/eremonoma becomes Northern Mouse-colored Tyrannulet Nesotriccus incomta, with subspecies eremonoma and incomta (for which the correct formulations are Nesotriccus incomtus, with subspecies eremonomus); and the polytypic group Mouse-colored Tyrannulet (Amazonian) Phaeomyias murina murina/wagae becomes Southern Mouse-colored Tyrannulet Nesotriccus murina, with subspecies wagae and murina (for which the correct formulation is Nesotriccus murinus; but the name wagae is invariant).
Los desacuerdos no intencionados ocurren cuando un grupo padre (B) se adelgaza al cambiar un grupo hijo (E) a otra parte del árbol taxonómico, provocando que las Identificaciones existentes del grupo padre sean interpretados como desacuerdos con las Identificaciones existentes del grupo hijo cambiado.
Identification
La ID 2 del taxón E será un desacuerdo no intencionado con la ID 1 del taxón B después del intercambio de ancestros
Si el adelgazamiento del grupo padre provoca más de 10 desacuerdos no intencionados, deberías dividir el grupo padre después de intercambiar el grupo hijo para substituir las identificaciones existentes del grupo padre (B) con identificaciones con las que no esté en desacuerdo,
