“…Although 95% of Myrsidea species parasitize passerine birds (order Passeriformes; Price et al, 2003), there are representatives parasitizing a few non‐passerine families, including barbets (order Piciformes, families Lybiidae and Capitonidae; Bueter et al, 2009; Soto‐Patiño et al, 2018), woodpeckers (order Piciformes, family Picidae; Ilieva, 2009), toucans (order Piciformes, family Ramphastidae; Hellenthal et al, 2005; Price et al, 2004) and hummingbirds (order Apodiformes, family Trochilidae; Dalgleish & Price, 2003a). Although there are many taxonomic studies of Myrsidea from passerines (e.g., Dalgleish & Price, 2003b; Dalgleish & Price, 2005; Kolencik et al, 2016; Kolencik et al, 2017; Kolencik et al, 2018; Kounek, Sychra, Čapek, Lipková, & Literák, 2011; Kounek, Sychra, Čapek, & Literák, 2011; Kounek et al, 2013; Price et al, 2005; Price & Dalgleish, 2006; Sychra et al, 2006; Sychra et al, 2007; Sychra et al, 2009; Valim & Weckstein, 2013), only a few authors have focused their study on those from non‐passerine birds (Carriker, 1949; Carriker & Diaz‐Ungria, 1961; Hellenthal et al, 2005; Price et al, 2004). How these non‐passerine avian host orders and families acquired their Myrsidea chewing lice remains a key unanswered question.…”
