A new species of Paraberothinae (Neuroptera: Berothidae) from mid-Cretaceous Kachin amber, with discussion of family affinity of the subfamily

Stygioberotha groehni sp. nov. (Neuroptera: Berothidae: Paraberothinae) is described from mid-Cretaceous Kachin amber. Its foreleg setation is very similar to that of S. siculifera Nakamine et al., 2020, but it is easily distinguished from that species by the presence of five spines on the ventral edge of the protibia (four in S. siculifera), forewing maculation (absent in S. siculifera), and a much shorter scapus. Analysis of wing venation, scapus and prothoracic structure, and female genitalia support the Paraberothinae as being a subfamily of Berothidae rather than of Rhachiberothidae.
