A redescription of &lt;jats italic=&quot;&quot;&gt;Myrsidea quadrifasciata&lt;/jats&gt; (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 of &lt;jats italic=&quot;&quot;&gt;M. quadrifasciata&lt;/jats&gt; are proposed and discussed. The new synonyms and their respective type hosts are: &lt;jats italic=&quot;&quot;&gt;Myrsidea anoxanthi&lt;/jats&gt; Price and Dalgleish, 2007 from &lt;jats italic=&quot;&quot;&gt;Loxipasser anoxanthus&lt;/jats&gt; (Gosse, 1847), &lt;jats italic=&quot;&quot;&gt;Myrsidea argentina&lt;/jats&gt; (Kellogg, 1906) from &lt;jats italic=&quot;&quot;&gt;Spinus magellanicus&lt;/jats&gt; (Vieillot, 1805), &lt;jats italic=&quot;&quot;&gt;Myrsidea balati&lt;/jats&gt; Mach&amp;aacute;ček, 1977 from &lt;jats italic=&quot;&quot;&gt;Passer montanus&lt;/jats&gt; (Linnaeus, 1758), &lt;jats italic=&quot;&quot;&gt;Myrsidea darwini&lt;/jats&gt; Palma and Price, 2010 from &lt;jats italic=&quot;&quot;&gt;Geospiza fuliginosa&lt;/jats&gt; Gould, 1837, &lt;jats italic=&quot;&quot;&gt;Myrsidea major&lt;/jats&gt; (Piaget, 1880) from &lt;jats italic=&quot;&quot;&gt;Plectrophenax nivalis&lt;/jats&gt; (Linnaeus, 1758), &lt;jats italic=&quot;&quot;&gt;Myrsidea serini&lt;/jats&gt; (S&amp;eacute;guy, 1944) from &lt;jats italic=&quot;&quot;&gt;Serinus serinus&lt;/jats&gt; (Linnaeus, 1766), &lt;jats italic=&quot;&quot;&gt;Myrsidea queleae&lt;/jats&gt; Tendeiro, 1964 from &lt;jats italic=&quot;&quot;&gt;Quelea quelea lathami&lt;/jats&gt; (Smith, A., 1836), &lt;jats italic=&quot;&quot;&gt;Myrsidea textoris&lt;/jats&gt; Klockenhoff, 1984 from &lt;jats italic=&quot;&quot;&gt;Ploceus cucullatus cucullatus&lt;/jats&gt; (M&amp;uuml;ller, 1776), and &lt;jats italic=&quot;&quot;&gt;Myrsidea viduae&lt;/jats&gt; Tendeiro, 1993 from &lt;jats italic=&quot;&quot;&gt;Vidua macroura&lt;/jats&gt; (Pallas, 1764). Intraspecific morphometric variability, relative genetic divergence (based on a 379 bp portion of the mitochondrial &lt;jats italic=&quot;&quot;&gt;COI&lt;/jats&gt; gene and a 347 bp portion of the nuclear &lt;jats italic=&quot;&quot;&gt;EF-1&amp;alpha;&lt;/jats&gt; gene), 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: &lt;jats italic=&quot;&quot;&gt;M. q. quadrifasciata&lt;/jats&gt; and &lt;jats italic=&quot;&quot;&gt;M. q. serini&lt;/jats&gt;, Neotropical Region: &lt;jats italic=&quot;&quot;&gt;M. q. anoxanthi&lt;/jats&gt;, &lt;jats italic=&quot;&quot;&gt;M. q. argentina&lt;/jats&gt;, &lt;jats italic=&quot;&quot;&gt;M. q. darwini&lt;/jats&gt;, Paleotropic Region: &lt;jats italic=&quot;&quot;&gt;M. q. queleae&lt;/jats&gt;, &lt;jats italic=&quot;&quot;&gt;M. q. textoris&lt;/jats&gt; and &lt;jats italic=&quot;&quot;&gt;M. q. viduae&lt;/jats&gt;.&lt;/jats&gt;&lt;/p&gt;
