Dichomeris syndyas is a moth in the Gelechiidae family. It was described by Meyrick in 1926. It is found in Asia Minor. The wingspan is 20-21 mm. The forewings are light grey partially or wholly suffused white and slightly sprinkled dark fuscous. The costa is more or less strongly and suffusedly mottled dark fuscous, and there is sometimes grey strigulation towards the dorsum and termen. There is an irregular dark fuscous spot on the fold about one-fourth and a dark grey transverse blotch in disc at one-third. The first discal stigma is represented by two approximated obliquely placed dark fuscous dots, the second by a transverse mark. There is also a marginal series of small dark fuscous dots around the apex and termen. The hindwings are light grey.
