Abstract:An intersex of partial masculinization, of the grasshopper Caryanda yini Mao et Ren, 2006, was reported for the first time. The individual possesses principally male characters, especially on well developed male genitalia and conical subgenital plate, and some typical female characters: tegmina brown, postocular bands on lateral abdominal tergite brown, tenth abdominal tergite without furculae on posterior margin, supra-anal plate triangular, cerci with apex straight, the individual is believed to be an intersex of partial masculinization. An unknown species of nematomorphs, found in the abdomen of the grasshopper, may have effects on ill-developed gonad and lead to the formation of the intersex.
