The tribe Atimiini LeConte containing two genera (Atimia and Paratimia) and about 12 species is distributed in East Asia and North America. The systematic position of the Atimiini has long puzzled the Coleopterist due to the Lamiid-like aspect of the Atimia. But the Atimiini has regarded as a tribe of the subfamily Aseminae since Webb (1912) associated the Atimia with the Asemum on the basis of larval characters. The tribe is very specialized in food habits, the species of Atimia are all restricted to trees of the Cupressaceae and Taxodiaceae, including Cupressus, Libocedrus, Thuja, Chamaecyparis, Juniperus, Taxodium, Sequoia, and their relatives. Members of the Atimiini are characterized by the combination of following features: head transverse, front short, vertical, mouthparts nearly horizontal; antennae 11-segmented, shorter than the body in both sexes, eyes large, moderately granulated, deeply emarginate, embracing antennal insertion; labrum transverse, ciliated; palpi unequal in length, the maxillary longer; pronotum quadrate, transverse; anterior coxae rounded, cavities usually not angulated, completely closed behind; mesonotum with a large, divided, stridulatory area; scutellum subquadrate; intermediate coxal cavities closed; metasternum deeply emarginate posteriorly, metepisterna narrow, attenuated behind; legs short; femora feebly clavate; tibiae armed with short spurs; wings with a closed cell in the anal sector. Here, we report the tribe Atimiini for the first time in Korea based on provisional identified species, Atimia spec. okayamensis Hayashi. We also provide a diagnosis, habitus photo, and drawings of diagnostic characters.
