Periacma iodesma Meyrick, 1910: 161 ; Caradja and Meyrick, 1935: 81; Gaede, 1939: 381; Clarke, 1963: 357.

Wing expanse: 16.0–18.0 mm.

Material examined: 2 „„, Hefei (31 ° 52 9 N, 117 ° 17 9 E), Anhui Province, 15 August 1978 and 11 June 1979, collector unknown GoogleMaps .

Distribution: China (Anhui, Hunan, Jiangsu, Shanghai, Sichuan), India, Vietnam.

Remarks: Periacma iodesma is closely allied to P. orthiodes Meyrick both superficially and in genitalia. It can be differentiated from the latter by the uncus with the caudal margin nearly straight, the gnathos with the anterior margin bluntly rounded, and the aedeagus with more than two tooth-like spines in the male genitalia.
