Remarks. Females from Sturnus vulgaris poltaratskyi have fewer submarginal setae (9–10) than lice collected from western Eurasia. As only a few specimens from S. vulgaris from continental Europe, Russia, and the Middle East have been examined, we are unable to establish whether these differences are due to clinal variation or indicative of these forms being distinct populations. Based on available material, we consider all of these lice to be St. sturni .
