Trogomorpha trogiformis
Trogomorpha trogiformis is a species of ichneumon wasp in the family Ichneumonidae, first described by Cresson in 1864. The genus Trogomorpha is characterized by distinctive morphological features including a compact body form and reduced wing venation. As a member of the subfamily Trogomorphinae (or related group within Ichneumonidae), this species represents a lineage of parasitoid 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.
