Eumayria floridana Ashmead

Eumayria floridana Ashmead
Eumayria multiarticulata Ashmead 

Distribution.--IN, IL, AR, TX, VA, FL

Biology.--Only a bisexual generation is known. Induces stem-swelling galls at the base of young sprouts of Quercus coccinea, falcata, ilicifolia, incana, laurifolia, myrtifolia, rubra, texana [buckleyi], velutina. Adult emerge in May through August. 

Eumayria enigma (Weld) New Combination

Callirhytis enigma
Trisoleniella enigma

Distribution.--IL, TX, VA, LA, FL

Biology.--Unisexual females only are known. Induce root galls on Quercus laevis, myrtifolia, nigra, rubra, texana. Adult emergence date is unknown. Adults can be dissected from galls by the beginning of November in FL.

Eumayria saltata (Ashmead) New combination

Andricus (Trisolenia) saltatus
Trisolenia saltata
Andricus saltatus

Distribution.--NC, FL

Biology.--Unisexual females only are known. Induces bud galls on Quercus falcata, laevis, incana, rubra. Galls in March-April, adults in April.

Andricus longipennis (Ashmead) New Combination

Neuroterus longipennis Ashmead
Eumayria longipennis Weld

Distribution.--FL

Biology.--Only the male is known. Induces stem-swelling galls on Quercus laurifolia and phellos. Adults emerge in May.

Eumayriella invisa (Weld) New Combination

Eumayria invisa Weld

Diagnosis.--Difficult to distinguish this species [from Eumayriella archboldi] on the basis of galls alone. Galls similar to those caused by Callirhytis crypta, Bassettia floridana. Adult wasps are necessary for precise identification.

Distribution.--FL

Biology.--Only a unisexual generation is known. Induces stem galls in the form of small larval cells hidden under the bark, usually without external evidence of galling on Quercus myrtifolia. Adults were dissected from galls in November. Adults emerge in January in south-central FL. 

Eumayriella archboldi, New Species

Distribution.--FL

Biology.--Only females are known. Adults emerge in December-January

Diagnosis [of Eumayriella invisa].--Difficult to distinguish this species [from Eumayriella archboldi] on the basis of galls alone. Adult wasps are necessary for precise identification.
