1A42FF71585E5E44AFAB0BFC89F1BB4C.taxon	diagnosis	Diagnosis. This species is remarkable for the absence of styli and the short tegmina and strongly reduced anal fields of hind wings in male, which can easily distinguish the males of E. udenostyla from all other species. The serrations of ootheca are distinctly reduced.	en	Han, Wei, Qiu, Lu, Zhu, Jing, Wang, Zong-Qing, Che, Yan-Li (2022): Exploring the diversity of Eupolyphaga Chopard, 1929 (Blattodea, Corydioidea): species delimitation based on morphology and molecular analysis.

Subgenital plate simple, posterior margin nearly straight, densely setose. Styli absent (Fig. 3 I, J). Genitalia: L 1 narrowed at base, genital hook (L 3) stout basally, gradually tapered at distal half, the hook roundly curved, apex sharp (Fig. 3 K). Male paratypes: Similar to the holotype, no significant variation. Female paratypes: Body length: 23.5 - 24.7 mm, body width: 17.5 - 18.1 mm. Body uniformly dark brown (Fig. 3 C, D), ante-clypeus and base of labrum white. Eyes and ocelli small, with a pair of large dimples between antennal sockets (Fig. 3 D). Distance between ocelli smaller than distance antennal sockets, and both smaller than interocular space (Fig. 4 B). Arolia and pulvilli absent. Supra-anal plate straight at posterior margin, lateral portions somewhat angular, posterior margin with a wide hollow medially (Fig. 4 D). Nymph. Similar to the female, body uniformly black or dark brown. Ootheca. Reddish brown. Serrations of keel small, blunt.
