A new species of thorny lacewing (Neuroptera: Rhachiberothidae: Paraberothinae) from mid-Cretaceous Burmese amber with novel raptorial foreleg structure

Abstract : A new species, namely Astioberotha coutreti sp. nov., of the thorny lacewing subfamily Paraberothinae, is described and illustrated from a complete individual preserved in mid-Cretaceous amber from Tanai, northern Myanmar. Astioberotha coutreti sp. nov. preserves nearly all the diagnostic characters of this subfamily, and differs from the type species of the genus Astioberotha owing to the fore femur with one long basal spine and 34 additional smaller spines; protibia bearing five distal spines; probasitarsus with two spines on inner edge located near mid-length; forewing with numerous maculation spots; intra-RP crossvein between RP3 and RP4 present (4rp3-rp4). Astioberotha coutreti sp. nov. together with the recent description of several other Paraberothinae species from the mid-Cretaceous Burmese amber, are used to discuss the palaeobiogeography of the subfamily.
