Unearthing hidden predators with micro-CT: A new Zasphinctus (Formicidae, Dorylinae) ant from Papua New Guinea

Zasphinctus Wheeler, 1918 is a rarely collected genus of predatory ants within the subfamily Dorylinae. This genus is distributed across the Old World, with its highest diversity in the Australasian region. A new species is described from Papua New Guinea, bringing the total number of known species in the genus to 30. Diagnostic characters distinguishing Zasphinctus papuasp. nov. from other Australasian species, along with a key for the species present in the island of New Guinea are provided. The new species description is enhanced through an in-depth morphological illustration of the holotype, derived from virtual examination of its 3D model created using x-ray microtomography (micro-CT). In addition, a cybertype dataset is provided based on micro-CT.
