青海省鸟蚤一新种(蚤目:角叶蚤科)

A NEW SPECIES OF BIRD FLEA (SIPHONAPT ERA: CERATOPHYLI-DAE) FROM QINGHAI PROVINCE, CHINA

角叶蚤属(Ceratophyllus Curtis,1832)原只有两个亚属,Smit在1983年将角叶蚤科有关属和亚属与角叶蚤属合并,同时建立两个新亚属,现包括下列几个亚属:(1)Amonopsyllus Wagner,1938,(2)Celeophilus Smit,1983,(3)Ceratophyllus Curtis,1832,(4)Emmareus Smit,1983,(5)Monopsyllus Kolenati,1857,(6)RosickyianaSmit,1972,本属共计有72种和亚种。亚属Emmareus计载有9种,近来又发表Ce-ratophyllus(Ceratophyllus)chasteli Beaucournu, Monnat & Launay,1982应归到此亚属中。本亚属青海只有粗毛角叶蚤(C.(Emmareus)garei Rothschild,1902)

Ceratophyllus (Emmareus) line sp. nov.Diagnosis: The new species is allied to C. (Emmareus) columbae (Gervais, 1844) and C. (Emmareus) borealis Rothschild, 1907. Their claspers and spermathecae are somewhat similar, but readily distinguishable by the following characters: In the male: (1) anterior margin of movable process with an acute process about 1/2 distance from apex in C. (E.) columbae and C. (E.) borealis but absent in the new species. (2) two spiniforms are present at the apical portion of VIII st. in C. liae and 3-5 spiniforms in the another two species. (3) in C. liae the apex of the crochet is thumb-like. In the female: (I) the apical margin of the 7th stemitc with wider, deeper sinus in the C. liae. (2) papilla is present at tail of spermatheca in C. (E.) columbae and C. (E.) borealis but absent in the C. (E.) liae.Types: Holotype (?), 2.8 mm, allotype(?) 2.7 mm; 2 (?) paratypes 2.3, 3.1 mm; 2 (?) para-types 2.6, 2.7 mm. All types are collected from Wulan County, west Qinghai in July, 1986, off Collumba rupestris by the first author. The types are deposited in the Department of Zoology in Qinghai Province Institute of Endemic Disease Control
