摘　　要：笔者赴甘肃省天水地区调查陆生贝类危害果树时,发现蜗牛危害各种果树苗木,经比对鉴定,发现主要危害种类系山华蜗牛Cathaica(Cathaica)orestias(Preston,1912)。山华蜗牛原始描述简单,仅附有一幅手绘的贝壳侧面图,且将此种归入Eulota属。笔者对山华蜗牛形态学进行了深入研究,对其生殖系统进行了解剖,并附生殖系统解剖图和描述,可为深入研究这一重要蜗牛物种提供参考。Cathaica （Cathaica） orestias （ Preston, 1912） was collected on 1 lth July 2010 in Qinzhou Town （ 34°06′N, 105°07′E）, Tianshui City （Gansu Province, China） , and the morphological characteristics was re-described. Subsequent- ly, the reproductive system of Cathaica （Cathaica） orestias （Preston, 1912） was anatomized and the specimens were de- posited in the Institute of Zoology, Chinese Academy of Sciences, Beijing, China. Cathaica （ Cathaica ） orestias （ Preston, 1912 ） （ Figs. 1 -3 ） Eulota （Cathaica） orestias Preston, 1912 J. Mollus. Stud. 10（ 1）： 11 - 15. Cathaica （Cathaica） orestias Yang, 2012 Shell ： Shell of Cathaica （Cathaica） orestias is small （ height 6.9 -8.2 mm ; diameter 11.5 - 14.0 mm）, thick, lus- trous, depressed turbinate, with 5 - 5.5 whorls. Shell is pale flesh-coloured, painted with a reddish brown supersutural band, which appears as a superperipheral band on the last whorl. Protoeonch is smooth. Sutures are deep. Shell has coarse- ly plieate and very fine wavy, spiral striae, which become more noticeable on the base of the shell. Umbilicus is rather nar- row, deep, hole-shaped. Columella is thin, outwardly expanded. Aperture is broad and irregular sub-lunate. Reproductive system： Atrium is short. Penis is long, without penis sheath and epiphallus. Penial retractor muscle is rather long and moderate thick. Dart sack is bag-shaped, containing one spear-shaped dart, without accessory sack. Mucous gland is composed of one bundle of tubular branches, contained about 20 mucous ducts. Free oviduct and vagina are rela- tively long. Spermatheca does not reach to the base of albumen gland, and lays on spermoviduct about 3/4 of length from the albumen gland. Ovotestis is composed of three or four clumps of finger-like lobes. Ovotestis duct is long. All soft part is milky white, without pigmentation spot.
