摘要
1984年从青海省的长尾仓鼠Cricetulus longicaudatus体上采得一种蚤,经鉴定,为怪蚤属Paradoxopsyllus Miyajima & Koidzumi,1909一新种,定名为窄窦怪蚤Paradoxopsyllus angustisinus,现记述如下: 窄窦怪蚤Paradoxopsyllus angustisinus,新种(图1—4) 鉴别特征 本新种仅知雌性,其形态特征与昏暗怪蚤Paradoxopsyllus pharoois(Jordan & Rothschild,1911)和副昏暗怪蚤Paradoxopsyllus paraphaeopis Lewis,1974颇为相似,但具下列特征可资鉴别:(1)前胸栉刺两侧共计20根;(2)
Paradoxopsyllus angustisinns, sp. nov.Diagnosis: Only (?) known. The new species is similar to P. phaeopis (Jordan & Rothschild, 1911) and P. paraphaeopis Lewis, 1974, but separable by the following characters: pronotum comb composed of 20 spines (fig. 1); the two longest bristles of hind- tarsal segment Ⅱ extend beyond apex of segment Ⅳ (fig. 2) ; the postero- apical margin of ST.Ⅶ has a narrow and deep sinus, and its ventral lobe much longer than dorsal one (fig.3-5) .Holotype(?), 2.7 mm long, paratypes 3(?), 1.9-2.7 mm long, taken on March 26, 1984 ex Cricetulus longicaudatus from Tongren County (about 2480m; 35°5' N, 102°E), Qinghai Province. All types are deposited in Qinghai Provincial Institute of Endemic Diseases Control.
