  • A single specimen in the subfamily Coralliophilinae in Family Muricidae was collected from Jeju-do by SCUBA diving survey. It was identified as Hirtomurex nakamurai Kosuge, 1985 based on external morphological characteristics. The Coralliophilinae species, commonly known as coral snails, are broadly distributed in tropical and temperate oceans from shallow subtidal zones up to 1,000 m in depth. To date, only four Coralliophila species in the subfamily Coralliophilinae have been reported from Korean waters. Prior to this report, Hirtomurex species has not been reported from Korean waters yet. As a result of this study, a total of five species in two genera of subfamily Coralliophilinae are recorded as Korean mollusk fauna.

  • A new species, Miscanthus wangpicheonensis of section Kariyasua, is described and illustrated from the morphological characteristics based on a type specimen collected from Gyeongsangbuk-do. This new species is similar to Miscanthus sacchariflorus (Maxim.) Hack., and M. longiberbis (Hack.) Nakai. The characters which distinguish the above two species are short leaves and racemes, callus hairs 1-1.5-times longer than spikelet, and well-developed awns of spikelet. The specific epithet, "wangpicheonensis", is based on the name of the locality where the new species is found. We assume this new species originated from the hybridization of Miscanthus sacchariflorus (Maxim.) Hack., and M. longiberbis (Hack.) Nakai. Miscanthus wangpicheonensis is found in only one locality in Uljin-gun, Gyeongsangbuk-do, Republic of Korea.

  • Petrorhagia nanteuilii (Burnat) P. W. Ball & Heywood (Caryophyllaceae), native to western Europe and western North Africa and an introduced or alien plant in South America, Australia, and Japan, was newly found in Gyeongsangnam-do, Korea. Petrorhagia is clearly distinguished from other genera by a bract at the base of calyx, which differs from Gypsophila L., and commissures at the sepals, which is different from Dianthus L. Petrorhagia nanteuilii grows on slopes and roadsides, suggesting that it is likely to have been introduced through the installation of green sites and road construction. A precise description, illustration, photographs, and a key to related genera and species is provided.
