Pediciinae crane flies belonging to the genus Dicranota Zetterstedt, 1838 of the Korean Peninsula were studied beginning in 1933, but only seven species have been recorded from North Korea so far; the genus was unknown from South Korea. Seventeen species were found during our studies on the Peninsula, three of them described as new: D. (Eudicranota) distincta Podenas, sp. nov., D. (Rhaphidolabis) seoi Podenas, sp. nov., D. (Rhaphidolabis) yeongokia Podenas, sp. nov. Ten new species are added to the Korean species list, five of them new for North Korea with total number reaching twelve, and eleven species new for South Korea. Habitat, elevation range, and seasonality data is presented for each species. Images of taxonomically important morphological characters, distribution maps, and an identification key for all Korean species of the genus Dicranota are presented.

A new species of Heterangaeus Alexander, 1925 crane flies (Diptera: Pediciidae) from north-central Mongolia with first description of the larva for the genus

Habitat characteristics, a description and illustrations are given for the early little-known larvae of Idioptera pulchella (Meigen, 1830). For the first time in the present study it has been found out that the structure of maxillae is the single character to distinguish the larvae of the genera Idioptera and Phylidorea. It has been established that this genus belongs to the clade Phylidorea – Hexatoma in the cladogram of hypothesized relationship of Tipuloidea (Oosterbroek & Theowald 1991). Also, it has been found out that the larvae of this species develop only in the lowermost portion of Sphagnum mosses at the margins of low-lying wooded swamps.

Review of the last instar larvae and pupae of Hexatoma ( Eriocera ) and Hexatoma ( Hexatoma ) (Diptera, Limoniidae, Limnophilinae)

A new species of crane fly (Diptera, Limoniidae), Elephantomyia (Elephantomyia) hallasana Podenas & Podeniene, sp. nov., from Jeju Island, South Korea is described. Adult and larval characters are illustrated. Elephantomyia (E.) hallasana sp. nov. is the only species of the genus Elephantomyia Osten Sacken, 1860 recorded from Jeju Island, South Korea. Habitat, elevation range, and seasonality data are presented. Distributional notes on E. subterminalis Alexander, 1954 in the Far East of Russia (Khabarovskiy and Primorskiy regions) are discussed. An identification key for all Eastern Palaearctic species of subgenus E. (Elephantomyia) is presented.
