Diagnosis
The genus
Aetheomorpha
can be recognized by the following characters: body cylindrical or suboval; head small, very short, smooth, perpendicular; mandibles very short; eyes small; antennae more or less robust, second and third antennomeres short and subconical, following antennomeres triangular; pronotum variable; scutellum large; elytra more or less lobed at sides; legs feeble, tarsi short, first tarsomere longer than second, third small, fourth slender; pygidium more or less exposed.
This genus is very closely allied to the genus
Smaragdina
, but is usually distinguished by the following characters: antennae more robust; elytra with more or less distinct epipleural lobes; tarsi short; pygidium exposed. According to
Jacoby (1908)
,
Aetheomorpha
was not well defined as a genus-level taxon and is most possibly a transitional form.
