Two new fossil genera and species of Cerocephalinae (Hymenoptera, Chalcidoidea, Pteromalidae), including the first record from the Eocene Author Blaeser, Marcel Author Krogmann, Lars Author Peters, Ralph S. text ZooKeys 2015 545 89 100 http://dx.doi.org/10.3897/zookeys.545.6470 journal article http://dx.doi.org/10.3897/zookeys.545.6470 1313-2970-545-89 61C2313F341741698E3559D134F884E0 61C2313F341741698E3559D134F884E0 Taxon classification Animalia Hymenoptera Pteromalidae Subfamily Cerocephalinae Gahan, 1946 Diagnosis. Intertorular area with prominence that can be a carina or tooth-shaped (also referred to as inner antennal process (iap)). Fore wing disc bare or with setae reduced to setal bases (pilose only in Pteropilosa gen. n.), with marginal fringe, fore wing always with thickened juncture between marginal vein and submarginal vein (parastigma), marginal vein elongate, postmarginal and stigmal vein shortened, postmarginal vein usually shorter than stigmal vein. Mesonotum with complete notauli. Hind tibia with two spurs. Key to extant and fossil genera of Cerocephalinae This key is modified after Krogmann (2013) and includes the two new fossil genera described herein.

Figure 2. Tenuicornus dominicus gen. et sp. n., showing general habitus and diagnostic characters. A General habitus in frontolateral view, showing rather long exerted part of the ovipositor B Head and mesosoma in dorsal view, mesosoma with polished mesonotum, foveolate notauli, and absent frenal line C Head in frontolateral view, with deep facial impression and enlarged setae at each side of lateral margin of the impression D Head and antennae in frontolateral view, at slightly different angle than C, with nail-shaped inner antennal process (iap) visible and highlighted with a red line; antennae inserted at ventral margin of eyes, with long scape, and 6-segmented, clavate funicle E Fore wing without a tuft of erect setae at parastigma (pst) and without pilosity or setal bases on wing disc. Scale: 500 µm (A); 200 µm ( B-D ).
