Synonyms and other taxonomic changes
This species used to be kept in synonymy with Vespula vulgaris (Linnaeus, 1758). However, V. vulgaris is restricted to the Palaearctic region (accidentally introduced to Australia and New Zealand). The confusion was recently rectified by Carpenter & Glare (2010). They showed that Vespula alascensis differs from V. vulgaris by the male genitalia, and some not so reliable colour characters (V. vulgaris often has yellow spots on the propodeum, V. alascensis [almost] never does). Genetically, V. alascensis is more similar to V. flavopilosa than to V. vulgaris.
Explanation of Names
V. alascensis was described by Packard (1870).
