Nothing is known about the biology of .

Identification

Distribution based on Regional Taxon Lists
Oriental Region: Taiwan.

Nomenclature

Taxonomic Notes
Leong et al. (2019): P. yuhuang was described from a single specimen, for which the external morphology cannot be clearly observed. We redescribed P. yuhuang based on the holotype and additional specimens. Although P. yuhuangis closely related to Ponera taiyangshen, differences in the antennal segment ratios and the form of the subpetiolar teeth can demonstrate that they are separated species.

Worker
Holotype. Head coarsely microreticulate, 1.23 times as long as wide, with concave posterior margin in full face view. Antennal scape relatively short, not reaching posterior margin of head; SI = 82; club consist of 4 segments. Eye small, consisting of a single facet. Petiolar node with parallel anterior and posterior margins and weakly convex dorsum in profile: posterodorsal corner forming a dull angle; posterior margin in dorsal view almost straight. Subpetiolar process without posteroventral teeth.

Measurements (mm). HL 0.49, HW 0.40, SL 0.33, WL 0.70, PNL 0.15, PH 0.30, DPW 0.20, TL 2.2.

Color. Brown; legs and mandible yellowish brown.

Type Material
Holotype. Worker, Nanshan-Anleng, Yilan Pref., 28. vii. -2. viii. 1988. Type depository. NIAES.

Leong et al. (2019): Type material examined: TAIWAN. Holotype. Worker, Nanshan-Anleng, Yilan Pref., 28 VII to 2 VIII 1988. Note that “Nanshan-Aleng” mean Nanshan to Anleng, Taiwan, holotype specimen was collected by the members of the Japanese Society of Soil Zoology using Berlese funnel (per. comm. Dr. Maromu Terayama).
