Revision of the genus Dryinus Latreille (Hymenoptera: Dryinidae) from mid-Cretaceous Kachin (Myanmar) amber
CRETACEOUS RESEARCH(2020)
摘要
Twelve new species of the genus Dryinus Latreille, 1804 are described from Kachin (Myanmar) amber, namely: dagger D. acutifrons sp. nov., dagger D. arakanesis sp. nov., dagger D. bamar sp. nov., dagger D. brachytarsis sp. nov., dagger D. burmensis sp. nov., dagger D. chin sp. nov., dagger D. katyae sp. nov., dagger D. laminatus sp. nov., dagger D. latitarsis sp. nov., dagger D. nadezhdae sp. nov., dagger D. parisei sp. nov., dagger D. taron sp. nov. The keys to fossil species of Dryinus from Kachin amber are proposed. All well identifiable Dryinus females belong to group 3. Kachin species of the genus appear to be morphologically similar to the species of the genus dagger Hybristodryinus Engel, 2005 known only from Kachin amber. Genera Dryinus and dagger Hybristodryinus were, obviously, the most abundant and diverse dryinid taxa at Kachin amber fauna (90% of all species), and species of these genera could have been parasitizing weakly jumping nymphs and small adults of planthoppers (Hemiptera: Auchenorrhyncha: Fulgoromorpha). The possible relations of studied dryinine wasps and their potential hosts are discussed in evolutionary aspect. (C) 2019 Elsevier Ltd. All rights reserved.
