description: Genus Aetheomorpha Lacordaire, 1848
Aetheomorpha Lacordaire, 1848: 311; Chapuis, 1874: 123; Jacoby, 1908:123; Clavareau, 1913: 45; Gressitt and Kimoto, 1961: 86; Regalin and Medvedev, 2010: 564.
Type species
Aetheomorpha nematoides Lacordaire, 1848 (designated by Jacoby 1908).
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.
