Abstract

Abstract : AUTHOR, N. & AUTHOR, P. December 2017. Article title. Alcheringa 42, 301-305. ISSN 0311-5518. Dysagrionidae are common in Paleogene sedimentary rocks, but rarely recorded in the Mesozoic. This family, however, is diverse in Burmese amber. A new dysagrionid damselfly, Palaeodysagrion youlini Zheng, Chang & Chang sp. nov., is described here based on a well-preserved specimen (holotype) in Burmese amber. The new damselfly provides wing apex and body characters for Palaeodysagrion . It differs from Palaeodysagrion cretacia in having Arc slightly distal of Ax2, the midfork slightly basal of the nodus, Cr and Sn almost perpendicular to RA and RP and in having a simple wing system. This is the fourth dysagrionid damselfly described from the Burmese amber.
