Herein is described a new species of Impatiens violascens B.U. Oh & Y.Y. Kim (Balsaminaceae) discovered on Bohyeon Mountain in Yeongcheon-si, Gyeongsangbuk-do, Korea. The new species is distinct from a closely-related species, I. textorii, by having a flower half the size that of I. textorii, sharply narrowed lower sepal, one half- to one time-coiled spur, and distal lobes of elliptical type laterally united petals. The key to these two species is provided.

A new species of Halacaridae, Copidognathus koreanus is recorded from the Korean coast mostly among intertidal coralline algae. The present new species comes close with C.auroroe Newell, C.curtus (Hall), C.richardi (Trouessart) and C.unolaskensis Newell. Morphological similarities and dissimilarities among them are discussed. This is the first report on the marine halacarid mite from Korea.

A new taxon, Viola ramiflora K. O. Yoo (Violaceae), from Jeju-do is described and illustrated. V. ramiflora shares several characteristics (pale purple flowers; triangular-ovate, ovate, or oblong leaf blades; winged petioles) with the related species V. hirtipes, V. japonica, V. phalacrocarpa, and V. seoulensis. However, this new species has branched cleistogamous and chasmogamous peduncles and oblong-ovate cleistogamous bracteoles.

An oribatid mite, Incabates barbatus sp. nov. in the family Haplozetidae is described herein from Korea. This new species is very similar to 1. major reported in Japan. However, prodorsal setae (ro & la) and head of sensillus are smooth in 1. major while barbs are found on the outer margin in the middle of rostral seta (ro) and lamellar seta (la) in addition to the presence of spinulae making the surface of head of sensillus rough in the new species. There are altogether 9 species described in the genus Incubates at present including the new species reported herein and keys to these 9 species are presented.
