Earliest behavioral mimicry and possible food begging in a Mesozoic alienopterid pollinator

Morphological insect-insect mimicry is known from few Cretaceous cockroaches and a beetle. Formicamendax vrsanskyi gen. et sp. n. (Blattaria, Alienopteridae) shows myrmecomorph features such as an elongated, smooth and black body, simple fenestrated hindwing, legs lacking protective spines. Elbowed or "geniculate "antenna is a typical character of advanced ants and weevils used for different forms of communication. Together with reduced mouthparts and specialized palps still preserved grasping food, they evidence specialized behavioral mimicry. The attached symmetric angiosperm pollen on hindleg can provide rare evidence of insect-flower relations.
