Ten species of the louse genusMyrsideabelonging to the “serini-species-group” have been reviewed. A redescription ofMyrsidea quadrifasciata(Piaget, 1880), the earliest described and valid species of this species complex, is given and a neotype for this species is designated. Nine new junior synonymies ofM. quadrifasciataare proposed and discussed. The new synonyms and their respective type hosts are:Myrsidea anoxanthiPrice and Dalgleish, 2007 fromLoxipasser anoxanthus(Gosse, 1847),Myrsidea argentina(Kellogg, 1906) fromSpinus magellanicus(Vieillot, 1805),Myrsidea balatiMacháček, 1977 fromPasser montanus(Linnaeus, 1758),Myrsidea darwiniPalma and Price, 2010 fromGeospiza fuliginosaGould, 1837,Myrsidea major(Piaget, 1880) fromPlectrophenax nivalis(Linnaeus, 1758),Myrsidea serini(Séguy, 1944) fromSerinus serinus(Linnaeus, 1766),Myrsidea queleaeTendeiro, 1964 fromQuelea quelea lathami(Smith, A., 1836),Myrsidea textorisKlockenhoff, 1984 fromPloceus cucullatus cucullatus(Müller, 1776), andMyrsidea viduaeTendeiro, 1993 fromVidua macroura(Pallas, 1764). Intraspecific morphometric variability, relative genetic divergence (based on a 379 bp portion of the mitochondrialCOIgene and a 347 bp portion of the nuclearEF-1αgene), geographical distribution, and host associations, including 8 new host records for these lice, are discussed. Taking into consideration these parameters we suggest that the only way to deal with these taxa is to follow concept of subspecies with the following taxa and their geographic distributon: Palearctic Region:M. q. quadrifasciataandM. q. serini, Neotropical Region:M. q. anoxanthi,M. q. argentina,M. q. darwini, Paleotropic Region:M. q. queleae,M. q. textorisandM. q. viduae.
