The First Record on Host Insect of Allobethylus Kieffer The specimen examined is deposited at the Entomological Collection of Yeungnam University (YNU, Gyeongsan, South Korea). Allobethylus currently contains 10 species worldwide (Barbosa and Azevedo 2011) and only one species, Allobethylus tomoae, has Systematic accounts been recorded in South Korea (Lim et al. 2010). To date, we do not have any ecological information of the genus Family Bethylidae Haliday, 1839 since no host of Allobethylus has been recorded.
