Mycterothrips fasciatus Masumoto & Okajima, 2006

This species exhibits some variations in ocellar setae I and the CPS of abdominal tergite IX. It was described by Masumoto and Okajima from about 150 females and 5 males collected in various parts of Japan, and also recorded from Malaysia. These authors stated that ocellar setae I present, but on abdominal tergite IX only the posterior pair of CPS present. In contrast, Yan et al. (2018) recorded this species in China from 23 females and 3 males, but although ocellar setae I present on most of these, two individuals lacked ocellar setae I, and one specimen had only a single ocellar seta present. Moreover, 16 females had two pairs of CPS on abdominal tergite IX, whereas six individuals had only the posterior pair. The same condition is present in the Japanese species M. japonicus , number of CPS on tergite IX seems to be variable(Masumoto pers. comm.2022). Thus variation in these character states requires further study, to determine their stability and reliability for distinguishing species .
