I, but their color pattern, labial triangle setae, chaetotaxy on Abd. II and III and ungual inner teeth are different as shown in Table 1.	en	Chai, Rui, Ma, Yitong (2017): Two new species of Willowsia (Collembola: Entomobryidae) from Yunnan Province, China.

03858B3CFFDFF336FDDCFC96FAFA29E8.taxon	discussion	Remarks The new species can easily be distinguished from the other species of the genus by their color pattern, except for the Vietnamese species Willowsia bartkei Stach, 1965. Both new species have blue pigment on the dorsal part of Abd. II and III and on the median and posterior parts of Abd. IV centrally, but there is no blue pigment on Abd. I posteriorly and Abd. II and III laterally in the former, whereas pigment is present in the latter. The other differences, such as chaetotaxy and scales, are listed in Table 2.	en	Chai, Rui, Ma, Yitong (2017): Two new species of Willowsia (Collembola: Entomobryidae) from Yunnan Province, China.
