The female of M. povedai is distinguished from those of other species of Myrsidea by: (1) well-developed hypopharynx, (2) well-defined median gap in the rows of tergal setae and another gap between groups of setae on lateral side of tergites II–VII and the most central seta, and (3) enlarged metanotum with at least 23 setae. These characters place M. povedai close to M. campestris from Euneornis campestris and M. marini from Pezopetes capitalis. The female of M. povedai can be easily separeted by the abdomen without conspicuously enlarged tergites. Moreover, the male of M. povedai is characterized by a unique male genital sclerite, which is quite long, tapered apically, with a long median line, and without subapical processes. This is the first record of a chewing louse from this host and the first record of Myrsidea from the passerine family Bombycillidae. All 7 birds examined in Costa Rica in 2010 were parasitized with M. povedai.
