Diagnosis.
Members of the genus Evaniscus are distinguished from other Evaniidae by a combination of the following character states: Fore wing RS+M vein presence: absent; mesosternum length vs metasternum length: ventral margin of mesosternum length equal to ventral margin of metapectus length; head shape: hemispherical in lateral view; flagellomere number: 13; metasoma shape in lateral view: ovoid; mandibular teeth number: 2; metanotum sculpture: scrobiculate; mesoscutellum sculpture: foveate; metapectal-propodeal complex sculpture: areolate; vertex sculpture: foveate; carinae on gena presence: present; notauli presence: present; parapsidal signum presence: present; subantennal carinae presence: present; preorbital carinae presence: present.
