Subsp. diminuta (Houlbert, 1921)

Thyatira diminuta Houlbert, 1921: 107, fig. 4014. Type-locality: China, Yunnan, Tsekou. Holotype ♀ (BMNH).

Distribution. China (Sichuan, Yunnan).

Remarks. Laszlo et al. (2007) downgraded it to a subspecies of arizana first, but wrongly marked this nomenclature change as “stat. rev.” instead of "stat. nov.", on the page 84.
