Loxaulus vaccinii (Ashmead, 1887)

Solenozopheria vaccinii Ashmead, 1887: 134, 149 (only asexual females);
Compsodryoxenus humilis Weld, 1921: 190, 193 (asexual female and gall);
Loxaulus vaccinii (Ashmead); Weld (1951: 643);
Loxaulus humilis (Weld); Weld (1951: 643) [synonymized by Melika and Abrahamson (2000: 209)].

Solenozopheria Ashmead, 1887 was synonymized with Loxaulus Mayr, 1881 by Weld (1951: 643); hence Solenozopheria vaccinii was then recognized as Loxaulus vaccinii (Ashmead). This species had been described based on adult wasps reared from the wild low-bush blueberry Vaccinium angustifolium Ait. (as V. pensylvanicum Lam.) and the northern highbush blueberry V. corymbosum L. Melika and Abrahamson (2000) determined that Ashmead (1887) had incorrectly associated the galls with the adult gall wasps, and that the real gall inducer on blueberries was Hemadas nubilipennis (Ashmead, 1887) [Chalcidoidea, Ormyridae (after Burks et al. 2022)]. The actual hosts of L. vaccinii are oaks, Quercus chapmanii Sarg. and Q. stellata Wangenh. (Weld 1921). Also, Melika and Abrahamson (2000: 209) synonymized Loxaulus humilis (Weld, 1921) with L. vaccinii. For future reference in the text, L. vaccinii, an oak galler that does not gall blueberry, has not undergone any other taxonomic change and has never been included in Callirhytis Foerster, 1869. This information is critical for assigning hosts for parasitoid species (see below).
