Diestrammena (Gymnaeta) tonkinensis Kim, T. -W. & Hong Thai Pham, 2014. Zootaxa, 3811 (1): 65.

Distribution. Vietnam (Hoa Binh province)*. ‘*’ denotes the type locality.

Diagnosis. This species is extremely close to T. (G.) racovitzai Chopard, 1915 , it differs from it by the hind tarsus, which is a little more slender, by the large internal spur almost at the apex of the metatarsus, by more distinct tibial spines and by the hind metatarsus, armed almost to apex ( Fig. 1 ). Corresponding characters of T. (G.) racovitzai Chopard, 1915 : supra internal spur of hind tibiae not exceeding ventral apex of hind metatarsus; ventral spines of hind metatarsus rather less ( Fig. 53 ).

Specimen not studied.
