Hexatoma crane flies (Diptera, Limoniidae) of Korea.

Abstract

Hexatoma Latreille, 1809 is a large genus of short-palped crane flies with a worldwide distribution. Accounting for more than 60 percent of global species, 362 extant species occur in Asia. Prior to our study, Hexatoma crane flies on the Korean Peninsula (both the Democratic People's Republic of Korea and the Republic of Korea) had been studied for 90 years starting in 1930, but only three species had been recorded, with one of them being a misidentification. This study adds six species to the fauna of the Korean Peninsula, all of which belong to the subgenus H. (Eriocera) Macquart, 1838. General information on genus and subgenus morphological characters is presented in this paper, with a redescription of each species based on Korean specimens, as well as illustrations of both sexes, the elevation range, the period of activity, habitat information, general distribution, and a distribution map for the Korean Peninsula. Three species H. (E.) ilwola Podenas, sp. nov., H. (E.) pianigra Podenas, sp. nov. and H. (E.) serenensis Podenas, sp. nov. are described as new to science. Hexatoma (E.) lygropis (Alexander, 1920) is deleted from the Korean species list as a misidentification. This publication is a continuation of our previous work on short-palped crane flies (Limoniidae) from Korea.
