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 : 56-57

Leptopilina leipsi Lue & Buffington sp. n.

Diagnosis.

Leptopilina leipsi (Figs 42-43 ) is distinguishable by flagellomeres F5-F10, in that the length is more than twice long as width of each flagellomere (Fig. 29 ). In Leptopilina clavipes and Leptopilina maia the length is 1-1.5 times the width of the flagellomere (Fig. 32 ). Moreover, the hairy ring is wide broken dorsally, and long and dense ventrally in Leptopilina leipsi (Fig. 30 ). This differs from other Leptopilina species in which the hairy ring is equally dense and of equal length (Fig. 33 ).

Description.

Coloration with head, mesosoma, metasoma black to dark brown, legs light brown. Malar sulcus present. Apical segment of maxillary palp 1-1.5 times as long as preceding segment. Terminal flagellomere with one basiconic sensillum. Basiconic sensillae present on 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-areoletate. Circumscutellar carina present, incomplete, laterally delimiting dorsal and ventral halves of scutellum, not present posteriorly. Latero-ventral margin of scutellum posterior to axillula smooth ventrally, weakly rugulose dorsally. Dorsal part of scutellum entirely foveate. Scutellar plate, in dorsal view, small to 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 absent. 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, longer hairs at ventral part.
