Remarks: Myrsidea quadrifasciata quadrifasciata was introduced to Chile by human agency with house sparrows ( Martínez-Piña & González-Cifuentes 2004: 219; Oyarzún-Ruiz et al. 2021: 2). The male and female depicted in photos by Oyarzún-Ruiz et al. (2021: fig. 4) do not belong to Myrsidea q. quadrifasciata because they clearly show well-developed pharyngeal sclerites, unlike those in Sychra et al. (2021: figs 19–20) (O. Sychra pers. comm. Aug. 2021).
