本文报道采自云南景东的景东大锥蚤Ｍａｃｒｏｓｔｙｌｏｐｈｏｒａｊｉｎｇｄｏｎｇｅｎｓｉｓｓｐ．ｎｏｖ．和采自四川黑水的黑水大锥蚤Ｍ．ｈｅｉｓｈｕｉｅｎｓｉｓｓｐ．ｎｏｖ．两个新种。并与在西南几省广为分布的无值大锥蚤Ｍ．ｅｕｔｅｌｅｓ（Ｊｏｒｄａｎ＆Ｒｏｔｈｓｃｈｉｌｄ，１９１１）的形态特征相比较。
Macrostylophora jingdongensis sp. nov. (Figs. 1-4)Near to M. euteles Jordan & Rothschild, 1911, but could be distinguished by: immovable process of clasper with a row of 5 small bristles on the inner side, instead of 3-4 inM. euteles. Upper portion of movable process narrower, being 5/10 at the narrowest levelto the lowest margin, instead of being 6/10 in M. euteles. First spiniform of the group of 4at the posterior margin of the movable process situated submarginaly instead of marginal inM. euteles. Dorsal lobe of the aedeagal crochet short, only reaches 1/3 of the posterior lobe,posterior lobe extraordainaly narrow. ♀ apex of 7th sternite sloping downwards, withoutsinus and the ventro-posterior corner do not forming a lobe. Bulga of spermatheca verybroad, almost circular in outline, being almost 3 times as broad as the hilla.Body length, j 2. 1 mm, l, 2. 8--3. 0 mm.Holotype /, paratypes 3 4 4, Caoling (24'N, 101'E)', Jingdong, Yunnan, Oct.1965, off Dremomys rnfigenis I LI Zhi---clang.MaCrostylophora heishaensis sp. nov. (Figs. 5--8)Near to M. jingdongensis sp. nov. and M. euteles, but could be distingshed by the following characters:/ immovable process of clasper with a row of only 2--3 small bristles, fewer than those two species. Upper portion of movable process narrower, being 4/10 at thenarrowest level to the lowest margin, instead of being 5/10 and 6/10 in those two species.All of the 4 subspiniforms at the posterior margin of the movable process situated marginal,the second of which being pale and slender, the other three being dark and stout. Dorsallobe of the aedeagal crochet broad, only slightly shorter than the posterior lobe. Posteriorlobe extra--ordinarily round and broad. I posteric--ventral corner of the apical margin of 7thsternite being somewhat truncate. Bulga of spermatheca almost as long as the hilla instead ofbeing longer than the hilla.Length,/ 2. 2--2. 3 mm, 4 2. 3--3. 0 mm.Holotype /, Heishui (32'N, 103'E) I Sichuan, Sept. 1960, off Aforemus sp.,paratype 1 4, Aug. 1960, paratypes 1 J, I l, Oct. 1960, paratype 1 4, by CHENNing--yu. All specimens are deposited in Guiyang Medical College.A table comparing the morphological characters of MacrostylOPhora eUteles. M. jing-dongensis sp. nov. and M. heishuicnsis sp. nov. is prepared.
