CHINA: Guangxi: Guilin City, Ziyuan County, Maoershan Antangping , 1442.85 m, 25.9047° N, 110.4669° E, 9.VII.2019, Gaosong Huang leg., No. GXNU 192821 [4 workers, GXNU] ; Guangxi: Guilin City, Maoershan , 29.VIII.2019, Zhilin Chen leg., No. G 194044 [4 workers, GXNU] ; Gaungxi: Guilin City , Longsheng County, Huaping Village , 1100 m, 25.0065° N, 109.9075° E, 11.VIII.2019, Zhilin Chen leg., No. GXNU 1940078 [1 worker, GXNU] ; Guangxi: Chongzuo City, Zuozhou Town, Pairu , 222 m, 22.56° N, 107.41° E, 11. VI .2016, Zhilin Chen leg., No. G160047 [1 worker, GXNU] ; Hainan: Qiongzhong Town, Limushan , 681 m, 19.14° N, 109.71° E, 4. IV.2016, Zhilin Chen leg., No. G 160131 [1 worker, GXNU] .

Diagnosis. Concolorous species, whole body yellow brown. Head distinctly longer than broad, lateral margins convergent anteriorly and posteriorly, with straight posterior margin and angular posterolateral corners. Eyes reduced, maximum diameter smaller than basal funiculus, ommatidial edge ambiguous. Petiole in lateral view trapezoidal, with steep anterior and posterior margin. Head, dorsum of mesosoma and petiole with deep and coarse puncta; dorsum of first gastral segment deeply foveolate-reticulate.

Workers. HL 0.60–0.65, HW 0.45–0.51, CI 75–80, SL 0.25–0.30, SI 50–67, ED 0.10–0.12, MSL 0.70–0.85, PW 0.32–0.36, PL 0.30, PH 0.38–0.40, DPW 0.32–0.34, LPI 110–123, DPI 106–113, TL 2.66–3.16 (n=8).

Notes. The specimens of P. ganeshaiahi from China exactly match the original description of Aswaj et al (2021), except for the following features: in full-face view head subrectangular, lateral margins convergent anteriorly and posteriorly, posterior margin straight; in lateral view, subpetiolar process of petiole rectangular, with anteroventral corner rounded and posteroventral corner obtuse-angulate, and ventral margin straight.

This species is most likely to be confused with P. wighti , but is easily differentiated from the latter by antennae with 11 segments, subpetiolar process rectangular, anteroventral corner rounded and posteroventral corner obtuseangulate, body yellow brown.

Distribution. China (Hainan, Guangxi), India.
