Phenacoleachiidae

Definition

A family of scale insects (Hemiptera: Coccomorpha) endemic to New Zealand, comprising two described species in the single genus *Phenacoleachia*. These insects are found only on the South Island and certain offshore islands, representing a highly restricted relict distribution among the typically cosmopolitan scale insect fauna.

Etymology

Example

*Phenacoleachia zealandica* and *Phenacoleachia australis* are the two species comprising this family, both restricted to southern beech (*Nothofagus*) forests in New Zealand.

Usage Notes

A rare example of a scale insect family with both generic and specific diversity limited to a single genus and two species. The family's restricted range contrasts sharply with the typically widespread distributions of most scale insect taxa. Specialists note its placement within the broader Coccomorpha remains under study due to its unusual morphology and biogeography.
