Myrsidea, Literak, 2017

Literak, Ivan, 2017, Where are the species limits? Morphology versus genetics in Neotropical chewing lice of the genus Myrsidea (Phthiraptera: Menoponidae), with description of three new species, Zootaxa 4324 (1), pp. 161-179 : 174

Myrsidea sp. 2

Material examined. Ex Trichothraupis melanops (Vieillot, 1818) —Black-goggled tanager ( Thraupidae ): 1♂, San Rafael National Park, Paraguay (26°30'S, 55°47'W), 20 Aug. 2012, I. Literak.

Remarks. This is the first record of a chewing louse from Trichothraupis melanops . A portion of COI gene was sequenced from our single male specimen from T. melanops (GenBank accession number KY249558 ). Comparing our sequence with other known sequences of Neotropical Myrsidea , the closest was Myrsidea fusca ( Carriker, 1903) (A/N FJ 171267 ) with a sequence divergence of 16.0%. Furthermore, Myrsidea sp. 2 is morphologically very close to M. patersoni Price & Johnson, 2009 (A/N GQ454448 ), but the net average pdistance between these two species is 18.5%. These divergences would justify the recognition of our specimen as a separate species. However, having only one male is insufficient for an adequate description of a new species.
