03BE075BFFCDFFA717B8FBC2FF75B7D0.taxon	etymology	Etymology. Named after the absence of chaetae on tenaculum, from the Latin absens: absent, missing.	en	Yu, Daoyuan, Deharveng, Louis, Zhang, Feng (2014): New species of Monodontocerus (Collembola: Tomoceridae) from southern China with diagnostic notes on the genus and introduction of new taxonomic characters.

03BE075BFFCDFFA717B8FBC2FF75B7D0.taxon	discussion	Remarks. This species is different from other Monodontocerus species mainly in the pattern of interocular chaetotaxy (2, 1, 2 while the others have 2, 3 or 2, 5) and the absence of chaetae on tenaculum (at least one present in other species). Besides, its antenna is distinctly longer than body, while other species have antennae shorter than body (Table 2). The most distal spine on the basal part of dens is nearly as large as large spines on the medial part, but the difference in size between small and large spines on the basal part is not as distinct as it is on the medial part.	en	Yu, Daoyuan, Deharveng, Louis, Zhang, Feng (2014): New species of Monodontocerus (Collembola: Tomoceridae) from southern China with diagnostic notes on the genus and introduction of new taxonomic characters.

03BE075BFFC7FFAA17B8FBBBFB8BB5CC.taxon	discussion	Remarks. Monodontocerus mulunensis sp. nov. is recognizable by a combination of characters of chaetotaxy, foot complex and furca (Table 2). It has 2, 3 interocular macrochaetae, which is different from the 2, 5 pattern in the three previously described species M. modificatus, M. odongnyeoensis and M. leqingensis.
