Distribution map of Undeuchaeta sp. by geographical zones
For Mulyadi (2004, p.54) this species resembles U. magna Tanaka (= U. incisa Esterly, 1911), but is distinguished from the latter by the shape of crest, the completely fusion of cephalon and 1st thoracic segment, the presence of a lateral process on right urosomal segment 1, the shape of posterolateral ends of last thoracic segment, and its smaller size.
