Trogomorpha trogiformis
(Cresson, 1864)
Trogomorpha trogiformis is a of ichneumon in the Ichneumonidae, first described by Cresson in 1864. The Trogomorpha is characterized by distinctive morphological features including a compact body form and reduced wing venation. As a member of the Trogomorphinae (or related group within Ichneumonidae), this species represents a lineage of wasps. The specific epithet 'trogiformis' refers to its resemblance to beetles of the family Trogidae (hide beetles), an example of mimicry or convergent body form.

Identification
Trogomorpha are distinguished from other ichneumonid by their -like, compact body form with shortened wing venation and robust hind legs. T. trogiformis specifically can be recognized by its trogid-like appearance—rounded, convex body with shortened -like wing covers and dark, often sculptured . The are relatively short for an ichneumonid, and the ovipositor is typically concealed or reduced.
