Abstract: The present paper deals with chromosome numbers, sex determination and chromosome behavior in 19 species of Chinese fulgoroids. Karyotype with 2n=28(26+XO) is suggested to be the ancestral type in Fulgoroidea. The relationship between Fulgoroidea and Hemiptera is very close because of sheathed testes and meiotic prophase Ⅰ with a typical diffuse stage in Fulgoroidea.

Key words: Fulgoroidea, karyotype, chromosome, meiosis
