<p><strong><em>Archaeoserphites engeli </em></strong><strong>sp. nov., the first archaeoserphitid wasp in Burmese amber and first known archaeoserphitid female (Hymenoptera, Archaeoserphitidae)</strong></p>

Burmese amber is currently the most popular and prolific source of fossil Hymenoptera, yielding a plethora of diverse and often unique fossils (Ross, 2020), and so vastly broadens and deepens our understanding of the mid-Cretaceous insect diversity in tropics in the midst of Tethys Ocean (Rasnitsyn & Öhm-Kühnle, 2018a; Zhang et al., 2018a). Parasitic wasps of the extinct superfamily Serphitoidea are a common, yet very unusual component of the Cretaceous microhymenopterans (Gibson et al., 2007; Engel, 2016; Rasnitsyn & Öhm-Kühnle, 2018a, b, 2020). Of them, Archaeoserphitidae represent a most basal and least explored branch known from a single find of two males in a piece of a comparatively ancient (Barremian) Lebanese amber (Engel, 2016). We identified the first female of Archaeoserphites Engel, 2016 in the comparatively younger, mid-Cretaceous Burmese amber and present its description in the publication on hand.
