Reevaluation of the subfamily Cretanallachiinae Makarkin, 2017 (Insecta: Neuroptera) from Upper Cretaceous Myanmar amber

A new genus with a new species, Oligopsychopsis penniformis gen. et sp. nov., is described from the Upper Cretaceous Myanmar (Burmese) amber, which is assigned to the subfamily Cretanallachiinae Makarkin, 2017 for sharing the siphonate mouthparts, bipectinate antenna and an unpaired ectoproct. Revealed by the new species, some controversial key morphological characters of Cretanallachiinae are clarified, i.e. the detailed structure of mouthparts and male terminalia, which allow us to reevaluate the systematic position of Cretanallachiinae. We concluded that the Cretanallachiinae have more similarities with the psychopsoid-like insects, and are reattributed to Psychopsoidea.
