(O.Sychra CR62). Deposited in INBio . Remarks. As we predicted in our previous paper ( Sychra et al. 2007 ) Myrsidea lice from this host represented a unique species that was subsequently described as new by Price et al. (2008) . Since our specimens collected from the type host differ a little from the original description of M. lightae , we mention these differences here [setal counts and dimensions mentioned by Price et al. (2008) are in parentheses]: Male (n = 2) . Mean length of head seta 10, 0.055 (n=3); seta 11, 0.107 (n=3); ratio10/11, 0.52. Metanotal margin with 11–13 (13–19) setae.
