Lue, Chia-Hua, Driskell, Amy C., Leips, Jeff & Buffington, Matthew L., 2016, Review of the genus Leptopilina (Hymenoptera, Cynipoidea, Figitidae, Eucoilinae) from the Eastern United States, including three newly described species, Journal of Hymenoptera Research 53, pp. 35-76 : 58-59

Leptopilina maia Lue & Buffington sp. n.

Diagnosis.

Leptopilina maia (Figs 44-45 ) is the second most common species in our collections and shares similar morphological characters with both Leptopilina clavipes and Leptopilina leipsi . In Leptopilina maia , the M vein is represented by a relatively clear trace vein that can be seen on the wing (arrow, Fig. 27 ). In Leptopilina clavipes and Leptopilina leipsi this trace vein is absent (Figs 24 , 26 ). Leptopilina maia (Fig. 31 ) also has a deep impression on posterior margin of the metapleuron like Leptopilina clavipes (Fig. 23 ) but the edge of posterior metapleuron is clear and the impression not connected to the propodeum.

Description.

Coloration with head, mesosoma, metasoma black to dark brown, legs light brown. Malar sulcus present, with adjacent groove. Apical segment of maxillary palp 1-1.5 times as long as preceding segment. Terminal flagellomere with one basiconic sensillum. Basiconic sensillae present on F1, F2, and F5-F11. Placoidal sensilla present on F5-11. Number of ridges on pronotal plate in lateral view 2. Sculpture on mesoscutum absent, with sparse long hairs. Dorsal surface of scutellum foveate-areolet. Circumscutellar carina present, complete, delimiting dorsal and ventral halves of scutellum. Latero-ventral margin of scutellum posterior to axillula entirely smooth. Dorsal part of scutellum entirely areolate. Scutellar plate, in dorsal view, small or medium sized, exposing small part of scutellum. Posterior impression of metepimeron present but not well defined. Anterior impression of metepisternum, immediately beneath anterior end of metapleural carina, present, small and narrow. Wing vein M present but not well defined. Inter propodeal carinae space setose, too dense to see underlying surface. Horizontal carina running anteriorly from lateral propodeal carina not visible, setae too dense. Surface of petiole longitudinally costate, ventral keel absent. Setal band (hairy ring) at base of tergum 3 present, interrupted dorsally, ventrally, dense hair.

Etymology.

Leptopilina maia is named in honor of the mother of the first author. The name maia means ‘mother’ in Greek form. Here we also use maia is to show our appreciation for Mother Nature and also the women who nurtured us growing up. Moreover, parasitoids, in general, are good mothers that have amazing strategies to find suitable hosts for their offspring. This name is a noun in apposition.
