A microscopic examination of genus Nephotettix individuals which are collected in 1963 by Rinichi KAWASAKI and in 1967 by Isoko HATTORI in Thailand, revealed four distinguishable species for classifying as follows: N. impicticeps, N. apicalis, N. parvus, and N. malayanus. N. apicalis and N. parvus had many individual differences together with slightness of blackening in the female. The black submarginal band on the head of N. apicalis and N. parvus appeared between the compound eyes or between ocelli. In some of the two species, the black submarginal band disappeared in its middle part.
