【摘要】 <正> 前额蚤后凹亚种Frontopsylla(Orfrontia)frontalis postcurva,新亚种 鉴别特征:新亚种♂不动突较短、♀第7腹板后缘内凹浅而较小,与前额蚤天山亚种F.(Orfrontia)frontalis dubiosa Ioff(1946)及前额蚤贝湖亚种F.(Orfrontia)frontalis baikal Ioff(1946)较相似。但新亚种♂第8腹板后缘有一宽凹,而在天山亚种及贝是湖亚种均为圆凸,因此易于鉴别;但♀区别甚微,通常后凹亚种后足第2跗节长端鬃较长,接近或达到第4跗节端,而在天山亚种及贝湖亚种则较短、通常仅达后足第3跗节之1/2处。更多还原
