Diagnosis

Based on the presence of sickle-shaped sensilla on the male flagellomeres and the dorsoventrally compressed mesosoma (wider in dorsal view and high in lateral view), the new species belongs to the genus Ceraphron . Ceraphron krogmanni differs from all other Ceraphron species by the presence of a proximomedial harpal brush (mhb:Fig. 4c, d), the presence of ventromedial and dorsomedial ridges of the basal ring (vmr, dmr:Fig. 4a, b) and the unusually large male genitalia Fig. 2b (more than half the length of the syntergum in C. krogmanni whereas less than 1/3 of the syntergum in other Ceraphron species).

Etymology

The species epithet is a patronym, honouring Lars Krogmann, Staatliches Museum für Naturkunde Stuttgart, who collected the specimens observed in this study.
