Abstract We describe † Cretovelona orussopteryx n. gen. & sp., a female orussoid from mid‐Cretaceous Kachin amber. examine the fossil with synchrotron scanning and integrate it into an existing morphological data set for Orussoidea. is placed as sister to crown group Orussoidea by Bayesian phylogenetic analyses. It unique in displaying combination of plesiomorphic (e.g. 12 antennomeres, exposed ovipositor sheaths, partly internalized that does not extend further than anterior part abdomen) apomorphic characters antenna club, fore tarsus 3‐segmented) display intermediate stages evolution host detection mechanism fully extant Orussidae. The wing venation even more reduced observed Orussidae, likely correlated small body size (<2 mm).
