Phasia chilensis

(Macquart, 1851)

Phasia chilensis is a tachinid fly in the Phasia, a large and taxonomically complex group of flies. The was originally described as Hyalomya chilensis by Macquart in 1851 and has undergone significant taxonomic revision, with four junior synonyms recently synonymized under it. As a member of the Phasiinae , it likely functions as a parasitoid of true bugs (Hemiptera), though specific records for this species require confirmation from the primary literature. The genus Phasia exhibits substantial morphological diversity and has a broad distribution across multiple continents.

Identification

Phasia chilensis can be distinguished from related based on the diagnostic characters established in the revision by Sun and Marshall (2003), which synonymized P. peruviana, P. pollinosa, P. auricaudata, and P. dimidiata under this name. Specific external morphological features distinguishing it from other Phasia species are detailed in the original description and subsequent revision, though these require examination of the primary taxonomic literature. The species belongs to one of six species-groups defined within the redefined Phasia.

Distribution

Records indicate presence in North America (GBIF) and South America (type locality implied by epithet and synonym P. peruviana). The species epithet 'chilensis' suggests Chile as part of its range, though precise distribution boundaries require verification from the primary revision.

Ecological Role

As a tachinid fly in the Phasiinae, P. chilensis likely functions as a of true bugs (Hemiptera), consistent with the known of related Phasia . However, specific associations for this species have not been extracted from the available literature and require verification.
