Loxaulus Mayr, 1881

Currently 14 species of Loxaulus are known from America north of Mexico, which are associated with different Quercus sections (Dailey 1977, Burks 1979, Dailey & Sprenger 1983, Melika & Abrahamson 2000): five species gall section Quercus, one species galls section Virentes, one galls section Lobatae, three gall section Protobalanus and for the other four species the hosts are unknown. Four new species of Loxaulus have recently been described from Panama and Mexico (Medianero et al. 2011, Pujade-Villar et al. 2014b), three from section Quercus oaks and one from a section Lobatae oak (although the latter record must be reviewed). As is the case with Dryocosmus, this variation in host section implies this genus may be polyphyletic. Herein we describe one new species, L. virginianae Melika & Buss, which is associated with Q. virginiana (in the oak section Virentes).
