本文记述了怪蚤属一新种——长方怪蚤Paradoxopsyllus longiquadraius sp.nov.,其正模及配模标本采自西藏通麦,宿主为白腹巨鼠;在分类讨论中把我国已知的26种怪蚤划分为5个种团。
Paradoxopsyllus longiquadratus sp. nov.The new species belongs to the curvispinus-group, it is related to P. custodis Jordan, 1932 in some ways. For example, the longest apical bristle of the hind-tarsal Ⅱ is shorter and does not reach the tip of the hind-tarsal Ⅲ. ♂: Fixed process is tapering and longer, being only a littele lower than the tip of movable process. ♀: There is a developted dorsal lobe and a distinct sinus on the posterior margin of St. Ⅶ.The new species is readily distingushiable from P. custodis by the fellowing diagnostic characters: ♂ (1) the shape of movable process of clasper is nearly erectfinger-like and much longer; (2) the shape of terminal portion of the distal arm of St. Ⅸ is very peculiar and specific; (3) the crochet of aedeagus is of nearly even width and rectangular in shape (the new species is named for that character) and little bigger than movable process; ♀ (4) dorsal lobe of posterior margin of St Ⅶ is large with a tapering apex and the sinus is quite large and somewhat triangular.Holotype ♂, 2.3 mm, long; allotype ♀ 2.4 mm. They were taken ex Rattus coxingi Swinhoe from Bomi County (Tong mai) (30.1°N, 90.0°W), Xizhang Aut. Region in March, 1985; paratypes 2 ♂♂, collected from Yigong of the same county (32.2°N, 94.9°W), off Apo-demus sp.. All types are deposited in the Academy of Military Medical Sciences, P. L. A., Beijing, China.I'aradoxopsyllus of China was first divided into 7 species-groups by Liu (1986). After further study of the genus we are of the opinion to revise the genus into 5 species-group and have given the characters for each group.These five species-groups are: (1) curvispinus-group, including curvispinus, cunodes, te-retifrons, longiquadratus (sp. nov.), repandus, conveniens, spinosus, naryni, integer, steno-tus, paucichaetus, calceiforma, rhombomysus and inferioprocerus; (2) intermedius-group, including termedius, phaeopis, and paraphaeopis; (3) alatau-group including alatau, scorodumovi and kalabokovi; (4) jinshajiangensis-group, including longprojcctus, diversus, j. jinshajiang-ensis and j. concavus; (5) magnificus-group, including magnificus and latus.
