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. 1

Material examined. Ex Tiaris fuliginosus (Wied, 1830) —Sooty grassquit ( Thraupidae ): 1♂, San Rafael National Park, Paraguay (26°30'S, 55°47'W), 22 Aug. 2012, I. Literak.

Remarks. This is the first record of a chewing louse from Tiaris fuliginosus . Our male differs morphologically from those of other Neotropical Myrsidea by a combination of several important features: (1) presence of median gap in most rows of tergal setae, (2) only 4 metanotal setae, (3) relatively high number of tergal setae, especially VIII with 9 setae, (4) genital sac sclerite without subapical projection on each side, and (5) small dimensions, especially TW, 0.37. This male Myrsidea from Tiaris fuliginosus probably represents an undescribed species, but having only one male is insufficient for an adequate description of a new species.
