Mesalgoides Gaud and Atyeo, 1967

Type species

Dermaleichus oscinum sensu Robin and Mégnin, 1877 (non Koch 1841), by original designation (= Dimorphus megnini Oudemans, 1937 ).

Twenty species of Mesalgoides , including the new species, are currently known worldwide ( Trouessart 1899; Spory 1965; Černý 1974; Shereef and Rakha 1981; Mironov 1997; Mironov and Pérez 2002; Mironov 2004; OConnor et al. 2005; Mironov et al. 2018; Wang et al. 2020). Mesalgoides sublobatus ( Trouessart 1899) was formerly referred to this genus by Mironov (2004), but after further analysis was concluded to belong to the family Analgidae (Mironov, pers. comm.). Known species were described from passerines of 10 families: Fringillidae , Leiothrichidae , and Paridae from the Old World; Furnariidae , Icteridae , Pipridae , Thraupidae , Turdidae and Tyrannidae from the Neotropical region; and Mimidae from the Nearctic region. In the New World (including Neotropical and Nearctic regions), undetermined Mesalgoides species were reported from 15 passerine families: Cardinalidae , Coerebidae , Conopophagidae , Cotingidae , Fringillidae , Furnariidae , Grallariidae , Icteridae , Mimidae , Parulidae , Passerellidae , Pipridae , Thamnophilidae , Thraupidae and Tyrannidae (see Kanegae et al. 2008; Valim et al. 2011; Barreto et al. 2012; Enout et al. 2012; Soto et al. 2013; Villa et al. 2013; Galloway et al. 2014; Hribar 2014; Silva et al. 2015; Hernandes and Flechtmann 2020). The record of Mesalgoides sp. on Galbula ruficauda (Galbuliformes, Galbulidae ) by Enout et al. (2012) requires confirmation. One additional undetermined species was reported from a woodpecker – Colaptes auratus (Linnaeus, 1758) – in Canada ( Galloway et al. 2014). A table with described species and their hosts was provided by Mironov et al. (2018).
