Steganoderma szidati n. sp. is described from the intestine of two freshwater fishes, Galaxias maculatus and G. platei (Galaxiidae), from Andean lakes in Patagonia, Argentina. This freshwater zoogonid species fits in the genus Steganoderma (sensu Bray, 1987) because of the length of the caeca and the position of the vitelline follicles. The new species is characterised by possessing 6-13 vitelline follicles situated between the anterior margin of the ventral sucker and the posterior margin of the testis. The gonads are in the anterior hindbody and the ovary is anterior to the right testis. The cirrus has two conspicuous spines at its distal end, and the seminal vesicle always exhibits a constriction. The excretory vesicle never reaches the level of the posterior margin of the testes.
斯氏隐殖吸虫新种（Steganoderma szidati n. sp.）是从阿根廷巴塔哥尼亚安第斯湖泊中的两种淡水鱼——黄斑南乳鱼（Galaxias maculatus）和普拉特南乳鱼（G. platei，南乳鱼科）的肠道中发现并描述的。由于盲肠的长度和卵黄滤泡的位置，这种淡水寄生吸虫物种属于隐殖吸虫属（按照布雷于1987年的分类定义）。该新物种的特征是在腹吸盘前缘和睾丸后缘之间有6 - 13个卵黄滤泡。性腺位于虫体后体前端，卵巢在右侧睾丸前方。阴茎在其远端有两个明显的刺，精囊总是有一个缢缩。排泄囊从不延伸到睾丸后缘的水平。
