Remarks

Noyes (2016) reported C. ensifer from California, apparently based on a single record by Essig (1915). However, Essig did not specifically state that C. ensifer occurs in California – he simply noted that Diaspidiotus juglansregiae is common throughout the southern portion of the state, and that C. ensifer (among several other species) has been reared from the scale. I have not found any other original record of this species from California, and therefore conclude that it is not present in the state, and that Essig’s statement was referring to host records from the eastern part of the country. Compere & Annecke (1961) presented a key to the world species. A species near to C. infuscatus was collected from Solano County (EMEC).
