印氏卵翅蝗的一例间性体(直翅目:卵翅蝗亚科)

An Intersex of the Grasshopper Caryanda yini Mao et Ren,2006(Orthoptera:Caryandinae)

首次报道印氏卵翅蝗Caryanda yini Mao et Ren,2006的一例偏雄性间性体。该个体总体特征为雄性,特别是雄性外生殖器发育完全,雄性下生殖板锥形,但出现了一些典型的雌性特征:前翅棕色、腹部两侧棕色、第十腹节背板后缘无尾片、肛上板三角形、尾须顶端直;腹内有一条线形动物寄生,未见性腺。推测该间性体的形成可能与线形动物的寄生有关。

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.
