Belenocnema (!) Treatae Mayr, 1881
Dryorhizoxenus floridanus Ashmead, 1882
Belonocnema kinseyi Weld, 1921 - Lund et al. (1998) confirmed through rearing that this was the unisexual generation of B. treatae.
Texas live oak (Quercus fusiformis, formerly Q. virginiana var. fusiformis)
Females of the bisexual generation induce leaf galls, from which unisexual females emerge. Unisexual females induce root galls (Lund et al. 1998).
In the absence of reared adults, the galls in this section are assumed to belong to B. treatae solely based on their having been found in Texas. Similar galls in Florida could be from this species or B. quercusvirens.
, adults of the two species are distinguished as follows:
B. quercusvirens - Spur on front tibia as long as metatarsus, twice as long as furcula. Middle tibia with distinct spur. Abdomen reaching far beyond apex of radial cell. No areolet.
B. treatae - Spur on front tibia one-fourth length of metatarsus, not longer than furcula. No spur on middle tibia. Abdomen reaching only to base of radial cell. Areolet present.
quercusvirens or treatae
