This was seen in west-central Korea in the elevation of 250 meters. It was crawling on rocky soil. If you can't identify, you can just at least tell me which family or genus it's in. Thank you!
CLOSED: What beetle?
It’s seemed to me that is a ground beetle, family Carabidae. There are numerous species of this family, so is very difficult to identify genus. Because of its small size maybe it's in tribe Lebiini, but I don't know distribution of genera in Korea.
For your curiosity, I found a document about insects of Korea in philatelic:

Could be a Tenebrionidae?
It’s difficult to know form the picture. Members of both families live in soil, are similar in size, and have dark colors. There are some differences from the BugGuide:
- Carabids have conspicuous prothorax and a narrow head, antennae are thread-like arising from between the mandibles and the large compound eyes
- Tenebrionids have eyes usually notched, antennae variable (may be thread-like) with 11 segments, insertion concealed from above
- Carabids have first abdominal sternite divided by hind coxae
- Tenebrionids have first abdominal sternite entire, not divided by hind coxae
- Tarsal formula of Carabidae: 5-5-5
- Tarsal formula of Tenebrionidae: (hind tarsi with 4 segments)
This definitely appears to be in the family Carabidae. Because of the lack of scale, I cannot be certain, but if the beetle is 18mm or more in length, it would likely be in the tribe Carabini, Carabus spp.
