Identification
in the Pelochrista are small tortricid moths, typically with wingspans under 20 mm, and require examination of genitalia or detailed wing pattern analysis for definitive identification. P. dilatana can be distinguished from by subtle differences in forewing pattern and male genitalia structure; precise identification relies on reference to original description and comparison with . The specific epithet "dilatana" may refer to dilated or expanded features of the genitalia or wing markings, though this requires verification from the original description.
Distribution
The original description by Walsingham (1895) and taxonomic records indicate this is known from western North America. Specific locality data from the and subsequent collection records would be required to establish precise range boundaries.
Similar Taxa
- Pelochrista eburataBoth are congeneric tortricid moths in the tribe Eucosmini; P. eburata has been documented from blacklight collections in California and may occur sympatrically with P. dilatana, requiring genitalic examination for separation.

Taxonomic note
Pelochrista is a large within Olethreutinae, with many described in the late 19th and early 20th centuries based on limited material. The biological and ecological data for most Pelochrista species, including P. dilatana, remain poorly known and would benefit from modern revisionary work.
