Species Undeuchaeta sp. - Plate 1 of morphological figuresissued from : Mulyadi in Published by Res. Center Biol., Indonesia Inst. Sci. Bogor, 2004. [p.54, Fig.29].
Female (from 07°29'S, 121°05'E): a, habitus (dorsal); b, forehead (lateral); c, posterior angle of last thoracic segment and urosome (lateral right side); d, posterior angle of last thoracic segment and genital segment (lateral left side); e, P2.

Nota: cephalon with high crest, in lateral view), apex of crest semicircular. Head and thoracic segment 1 fused (without suture or fusion), 4th and 5th fused.
Posterolateral ends of thoracic segment produced into asymmetrical short lobes, in lateral view, right side irregularly rounded and without prominence on distal corner.
Urosomal segment 1 with stout and large protuberance on right side medially; ventral spine near genital opening smaller than that of U. major Giesbrecht, 1888, but larger than U. magna Tanaka, 1957.

Rem.: 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.
