03F087A17A041059FF5CAE4AFE73F814.taxon	discussion	Remarks. Tomocerus nabanensis sp. nov. is characterised by absence of cephalic macrochaeta Pp 3 and mesothoracic macrochaetae a 4 and m 4, presence of two inner teeth on the unguis, 1 + 1, 1 pointed prominent chaetae on the furca, dorsal scales on the manubrium, a small spine between two large distal spines and uneven distribution of denticles on the dental spines. The new species resembles cave species T. postantennalis, Tomocerus dong Yu & Li, 2016 and Tomocerus deharvengi Yu & Li, 2016 in dental spine formula and number of the ungual teeth, but differs from the latter species in absence of the large PAO, different pattern of the dorsal chaetotaxy and presence of stronger tenent hairs. The general appearance and dental spine formula of the new species are also similar to those of T. folsomi, but the latter has more teeth on the unguis and smaller denticles on dental spines (Denis 1929). Critical characters discriminating T. nabanensis sp. nov. from similar species are listed in Table 1. Malformed dental spine formulas are found in one female, with 9 / 4, 1, 3, 1 on the right side and 6 / 7, 1, 1 on the left side, and in this case proximal spines on both sides are irregularly arranged, distal small spines on the right side are arranged in two rows.	en	Yu, Daoyuan, Yang, Xiaodong, Liu, Manqiang (2018): Three new species of Tomocerus from tropical zone of China (Collembola, Tomoceridae).
