摘　　要：本文报告荷币蚤属在我国初次的发现,包括3种,其中有一新种和一新亚种: 1.野生荷币蚤Stivalius ferinus(Roths.1908),采自云南芒市的鼩鼱Suncus sp.及黄胸鼠Rattus flavipectus。与Jordan及Rothschild二氏1922年原图及描述比较,云南的标本与南印度的标本在可动指上略有差异。另外根据二氏同年鉴别荷币蚤属及相近的4个属的检索表,本属应有前胸背板鬃两列以上,但云南的野生荷币蚤只有一列前胸背板鬃。 2.客氏荷币蚤二刺形亚种Stivalius klossi bispiniformis subsp.nov.采自福建顺昌及邵武的Rattus fulvescens huang、R.flavipectus及R.edwardsi edwardsi。与Jordan及Ro-thschild二氏在1922年,根据越南南部的标本描述的客氏荷币蚤Stivalius klossi(J.et R.,1922)比较,在可动指上有显著差异。认为这些是不同地区的变异,因此列为两个亚种:越南南部的标本为客氏荷币蚤客氏亚种,福建的标本均客氏荷氏荷币蚤二刺形亚种。雄性可动指的区别为:二刺形亚种者较狭而长,在曲折之前较狭窄,在曲折之后显然为削尖形。可动指背缘的骨化区较腹面者厚,在客氏亚种中则窄于腹面者。背缘在曲折处有较大的刺形鬃2个,客氏亚种则有3个较小的。 3.直指荷币蛋Stivalius rectodigitus sp.nov.,采自云南弥渡的黄胸鼠R.flavipectus。This paper records for the first time fleas of the genus Stivalius J. et R. 1922 fromChina. Three species and subspecies are encountered: 1.Stivalius ferinus (Rothschild, 1908), from Mang-shih, Yunnan, off Suncus sp. andRattus flavipectus. There is no marked difference between the Yunnan specimens andthose from South India, as described and figured by Jordan and Rothschild in 1922.But our specimens have only 1 row of bristles on the pronotum, while the south-ern Indian specimens, as well as other species of the genus, are provided with at least2 rows. 2.Stivalius klossi bispiniformis subsp. nov. from Shun-ch'ang and Shao-wu, Fukien,off Rattus fulvescens huang, R. flavipectus and R. edwardsi edwardsi. The main dif-ference of Stivalius k. bispiniformis as compared with the typical species which should be named Stivalius k. klossi, occurs on the movable finger of clasper. The finger ofthe new subspecies is narrower and longer, with its apex more acuminate. There aretwo larger spiniforms situated on the dorsal side of the curvature, while Stivalius k.klossi has three smaller ones. Incrassations of the dorsal side of the finger well de-veloped, much heavier than those on the under side, especially in the area of the cur-vature. In Stivalius k. klossi, the incrassations on the dorsal side of the finger arenarrower than those of the under side. Besides, the number of minute bristles both onthe under side behind the row of long bristles and on the dorsal side near the apexare fewer, being only 1-3, never 4. 3.Stivalius rectodigitus sp. nov. from Mi-tu, Yunnan,off R. flavipectus. A speciesnear to klossi, characterized by: that the dorsal and under sides of the movable fingerof clasper being straight and parallel, and the apex of the finger being strongly curveddownward, almost rectangular. The under side of the finger with a row of seven longbristles, with the last one situated very close to the apex. Duct of spermatheca longand rolled up in a spiral. Generic diagnosis and detaild descriptions of the three species are giv
