Description. Adult ( Figs. 1 f, 2f) with wing expanse 17.0–19.0 mm.

Female genitalia (Fig. 4e): Apophyses posteriores about twice as long as apophyses anteriores, extending to anterior 1/3 of abdominal sternite VIII, distal 4/5 thickened. Lamella antevaginalis heavily sclerotized, nearly rectangular, extending backward posterolaterally, forming nearly right-angled triangular plate. Antrum columnar. Ductus bursae as long as corpus bursae, basal 1/4 narrow, distal 3/4 expanded; ductus seminalis arising from distal 1/3 of ductus bursae, its basal half expanded, distal half narrowed. Corpus bursae rounded; signum placed at distal 1/3, small, irregularly rounded, with teeth.

Diagnosis. Spatulignatha olaxana can be separated from its congeners, except S. hemichrysa , by the blackish antenna, dark-brown costa of the forewing before middle and dark-brown fascia which runs obliquely from about 2/3 length of costa to before tornus, by the sacculus with an apical lobe that bears stiff hair-like scales in the male genitalia ( Fig. 3 f). This species is very similar to S. hemichrysa , and the differences between them are discussed under S. hemichrysa .

Distribution. China: (Fujian, Guangdong, Guizhou, Guangxi, Henan, Hubei, Hunan, Jiangxi, Sichuan, Taiwan, Yunnan, Zhejiang).

Remarks. Wu (1994) described this species on three male specimens. Park (2000) reported this species from Taiwan based on three males collected in Illan County. By comparison with the female genitalia of S. hemichrysa loaned from the Natural History Museum, we determined that the female of S. hemichrysa described by Gozmány (1978), from a specimen collected in Sichuan, China, is in fact the female of S. olaxana Wu.
