03A88104FFA37B51A59CFAFEF4C5AEBD.taxon	discussion	Remarks. The genus Multivesicula contains six species in the world: M. columbia Rusek, 1982, M. punctata Rusek, 1982 and M. dolomitica Rusek, 1982 described from Canada, M. giljarovi Rusek, 1982 from Russia, M. ampla Christiansen & Bellinger, 1980 from USA and M. aliciae (Palacios-Vargas & Díaz, 1996) from Mexico (Bellinger et al. 1996 – 2021). Multivesicula zhengi sp. nov. can be easily distinguished from all above known species by the presence of one pair of pso on Th. I and two pairs of pso on Th. II, pso formula as 11 / 122 / 11111, the presence of seta m 3 on Th. II and III and seta a 2 on Abd. V, and the weakly differentiated sensillum p 3 on Abd. V. The differences between all seven species in the genus are given in Table 2.	en	Gao, Yan, Bu, Yun (2022): New species and records of Tullbergiidae (Collembola, Poduromorpha) from Xinjiang province, Northwest China.

03A88104FFA47B52A59CF8C4F44EA8BF.taxon	discussion	Remarks. Wankeliella intermedia was originally described from Tuva of Russia, and recorded in North Norway and North Siberia later. The morphology of Chinese specimens is nearly the same as types. As noted by the author in the original description, the PAO of this species is not in the typical shape compared with other congeners. As a consequence, it was placed in the genus Wankeliella temporarily.	en	Gao, Yan, Bu, Yun (2022): New species and records of Tullbergiidae (Collembola, Poduromorpha) from Xinjiang province, Northwest China.

03A88104FFAA7B5EA59CF9DEF6AFAC47.taxon	discussion	Remarks. Mesaphorura critica was first found in sands in Greece. It is widely distributed in the world, from North Europe (Greenland and Norwary) to North Africa (Morocco, Senegal), from Spain to Russia, and also recorded from South Australia (Greenslade 1992). It was usually found in dry open habitats such as meadows or the shore, rarely in forest (Dunger & Schlitt 2011). We found it occurred in different kinds of forests of Xinjiang frequently and with high density.	en	Gao, Yan, Bu, Yun (2022): New species and records of Tullbergiidae (Collembola, Poduromorpha) from Xinjiang province, Northwest China.

03A88104FFA97B5FA59CF8C4F4D3ACC9.taxon	discussion	Remarks. Paratullbergia qilianensis is the largest Tullbergiidae species found in China till now which may reach 1.16 mm in length. It has fairly robust habitus and coarse body granulations. The body lengths of 24 adult specimens from Xinjiang are 0.75 – 1.05 mm. The morphology of most specimens from Xinjiang is as same as types. There is only one minor variation observed in 11 specimens from Harturege Park: seta p 4 on Abd. V as microseta (15 – 17 μm) and in medial position vs. as macroseta (42 – 45 μm) and distinctly in anterior position in the types (see Bu & Gao, 2019 b, Fig. 5). All collected sites of Tullbergiidae from Xinjiang Province in above are shown in Fig. 42. Six species of Tullbergiidae from Xinjiang Province can be separated by the following key.	en	Gao, Yan, Bu, Yun (2022): New species and records of Tullbergiidae (Collembola, Poduromorpha) from Xinjiang province, Northwest China.
