Diagnosis.

Udea cyanalis is similar to Udea prunalis, Udea inquinatalis, Udea orbicentralis -complex and Udea albostriata sp. n. with similar ground colour and maculation as mentioned in diagnosis of Udea prunalis, but can be distinguished from them by the semicircular produced process of pseudognathos with nipple-shaped end in male genitalia. In female genitalia, this species differs from Udea prunalis, Udea inquinatalis and Udea grisealis Inoue, Yamanaka & Sasaki by ductus bursae approximately 1.8 times the length of the corpus bursae, the corpus bursae with narrowly crescent-shaped accessory signum, but lacking the lanceolate signum; differs from Udea nebulatalis Inoue, Yamanaka & Sasaki by ductus bursae approximately 1.8 times the length of the corpus bursae and nearly round corpus bursae; differs from Udea proximalis Inoue, Yamanaka & Sasaki and Udea intermedia Inoue, Yamanaka & Sasaki by crescent-shaped accessory signum but lacking the lanceolate or pyriform signum; differs from Udea orbicentralis and Udea albostriata sp. n. by lacking the lanceolate signum.
