Zorotypus dilaticeps sp. nov., a remarkable zorapteran (Zoraptera) in mid-Cretaceous Burmese amber

A seventh species of fossil zorapteran (Zoraptera) in mid-Cretaceous Burmese amber is described and figured from an apterous female (dealate). Zorotypus (s. str.) dilaticeps sp. nov. is exceptionally large in body size (ca. 3.9 mm), and can be readily distinguished from all other extinct and Recent members of the order by its distinctive head morphology and by unique spination of the metafemur and metatibia. Our new find sheds further light on the diversity and morphological disparity of fossil zorapterans during the Late Mesozoic.
