原小蜂亚科是一个已灭绝的、仅寄生于茧蜂科的亚科，迄今为止最广泛接受的有7属7种。本文记述了一新属Burmabracon gen. nov.及二新种，即B. gracilens sp. nov.和B.新种Grossus sp. nov.，根据以下特征，将其归属于原盐生石首鱼亚科（Protorophylsalinae）：头具直颌，具圆口，触角节多于20个，背足完整，前翅无2 m-Cu，后翅有1 r-m和Cu。中生代的茧蜂化石记录表明，该科起源于早白垩世或更早。nbsp;（c）2021 Elsevier Ltd.保留所有权利。
Protorhyssalinae is an extinct, Cretaceous-only subfamily of braconid wasps hitherto comprising 7 genera and 7 species in its widest acceptance. A new genus Burmabracon gen. nov. with two new species, B. gracilens sp. nov. and B. grossus sp. nov. from the mid-Cretaceous Myanmar (Burmese) amber, are described and assigned to Protorhyssalinae, based on the following characters: head orthognathous and almost certainly cyclostome, antenna with more than 20 antennomeres, notauli complete, forewing with 2m-cu absent and hind wing with 1r-m and Cu present. The Mesozoic fossil record of the Braconidae suggests that the family originated in or before the Early Cretaceous.& nbsp; (c) 2021 Elsevier Ltd. All rights reserved.
