摘要我们首次在始新世早期的印度坎贝琥珀中发现了一种属于Tanytarsini族的摇蚊化石。已知最古老的已灭绝的tanytarsine属，Gujaratomyia Giuska & Zakrzewska，gen. nov.，的成年男性的基础上描述的G. miripes Giulika & Zakrzewska，sp. nov.该种具有独特的腿比例和胫甲。头部和生殖器特征的结合支持了Gujaratomyia和Cladotanytarsus是Tanytarsina亚部落中一个共同群体的假设。
ABSTRACT We present the first specific record of a chironomid of the tribe Tanytarsini from early Eocene Cambay amber, India (52–53 Ma). The oldest known extinct tanytarsine genus, Gujaratomyia Giłka & Zakrzewska, gen. nov., is described on the basis of adult males of G. miripes Giłka & Zakrzewska, sp. nov. The species displays an unusual leg structure with unique leg ratios and tibial armature. The combination of the head and genital apparatus characters supports the hypothesis that Gujaratomyia and Cladotanytarsus are members of a common group within the subtribe Tanytarsina.
