  • Caminus jejuensis n. sp was collected from depth of 20 m at Geomeunyeo, Seogwipo, Jejudo Island by a SCUBA diving from April 2004 to December 2008. This new species is similar to C. chinensis from China in the composition of spicules except for the spherasters and they differ in spicule size and growth form. This species has longer orthotriaenes and spherules, smaller sterrasters and oxyasters than those of C. chinensis. This species also has many spherasters in choanosome, but C. chinensis lacks. Morever, the new species is a massive shape with wrinkles, whereas C. chinensis is a club shape with smooth surface. Description and figures of the new species are provided.

  • The present study summarizes the occurrence, distribution and autecology of 12 taxa of the class Cyanophyceae collected from several swamps, reservoir and highland wetlands in South Korea from 2009 to 2012. A new species, Anabaena koreana sp. nov. and 11 taxa of blue-green algae newly recorded are described and illustrated. Anabaena koreana is similar to A. oumiana, A. spiroides and A. crassa in that the trichomes form regular coils. However, A. koreana is distinguished from these three species by the morphological characteristics of the vegetative cell, heterocyst, and akinet shape and size. This study considers 12 blue-green algal species, including a new species, Anabaena koreana sp. nov. and 11 species that are recorded for the first time in the Korean freshwater algal flora. Among them, the genus Nostochopsis Wood ex Bornet et Flahault 1886 had not previously been recorded in Korea.

  • Nine new species of genus Ircinia (Demospongiae: Dictyoceratida: Irciniidae) from Jejudo Island, Korea are described. All of the new species are distinguished from the others reported species of Ircinia by the skeletal structure, especially massive fasciculate primary fibres. The characters of genus Ircinia have primary fibres cored with foreign debris and no cored secondary fibres. Primary fibres are not easy to distinguish from secondary fibres if they are not cored. Secondary web has perforated plate or meshed net. All new species have loosely arranged skeletal fibres network.

  • Adult caddisflies were collected from 11 sites in Cheongdo-gun (Gyeongsangbuk-do) and Miryang-si (Gyeongsangnam-do) in the southeastern part of the Korean Peninsula. Collections on August 28 to 30, 2015, by aerial sweeping and light trapping, included one new species and four newly recorded species from the Korean Peninsula. Description of the new species Paduniella unmun Inaba and Park (Psychomyiidae), and re-description of the four species (Polyplectropus malickyi Nozaki et al., 2010, Tinodes furcatus Li and Morse, 1997, Cheumatopsyche tanidai $Ol{\acute{a}}h$ and Johanson, 2008, and Diplectrona kibuneana Tsuda, 1940) are provided. Additionally, we recognize that a larva described as Diplectrona KUa is the larval stage of D. kibuneana.

  • A new species, Burmoniscus phuketensis, is described from Ko Phuket, Thailand. The new species belongs to the group characterized by male pereopods 1 and 2 with enlarged and flattened carpi, including B. coecus (Budde-Lund, 1895), B. ferrarai (Schumalfuss, 1983), B. mossambicus (Ferrara and Taiti, 1985), B. rowei Taiti and Manicastri, 1988, and B. rakataensis Green, Ferrara and Taiti, 1990. Among them, this new species resembles B. coecus and B. rakataensis in the pigmentless body and the shape of pereonite 7 epimeron with acute postero-lateral corner, but is easily distinguished from both specie by the shape of telson. While the eyes are absent in B. coecus, they are present in this new species.

  • Thirteen species of sea lice (Copepoda, Caligidae) are described as parasites of marine fishes from Korea including three new species such as Pseudocaligus longipes n. sp. from Siganus fuscesens (Houttuyn), Lepeophtheirus tamladus n. sp. from Sebastes inermis Cuvier, and Lepeophtheirus gusevi n. sp. from Sebasetes schlegeli Hilgendorf. Remaining ten species are new to Korea: Caligus elongatus Nordmann, 1832; C. equulae Ho and Lin, 2003; C. fistulariae Yamaguti, 1936; C. laticaudus Shiino, 1960; C. rotundigenitalis Y$\ddot{u}$, 1933; Metacaligus uruguayensis (Thomsen, 1949); Lepeophtheirus atypicus Lin, Ho and Chen, 1996; L. parvulus Shiino, 1952; Anuretes quadrilaterus Shiino, 1954; and Pseudanuretes chaetodontis Yamaguti, 1936.

  • Nongeniculate coralline red algae are a common element of the Brazilian coastal zone, especially associated to coral reefs. During the course of ecological studies at Parque Municipal Marinho do Recife de Fora, two species of non-geniculate Corallinales were the major organisms covering the reef. Analyses of the vegetative and reproductive features of the species were analyzed; indicating that one new species of the genus Lithothamnion is proposed here based on the combination of several features associated with anatomy of the tetrasporangial conceptacles in relation to other species of the genus for which modern accounts are available. This new proposal along with other new species, new combinations and range extension of some species of the genus based in similar features clearly suggest that stability in species delimitation is possible. The second species found Pneophyllum conicum represents a range extension of more than 6,000 km from the Pacific in to the Atlantic Ocean suggesting that some nongeniculate species are widely distributed. The occurrence and abundance of these species supports and emphasizes the need for an extensive taxonomic reassessment of coralline red algae in the context of Brazilian coral reef biodiversity.

  • Spongicola tropicanus, a new genus and species of the family Eunicicolidae, and Asterocheres brevisurculus, a new species of the family Asterocheridae, are described as copepods associated with the sponge Phyllospongia foliascens (Pallas) from the Moluccas. Spongicola is the second genus of the family and may be characterized by a two-segmented prosome, the absence of leg 3, and the presence of leg 5. Asterocheres brevisurculus may be charecterized by one-segmented mandibular palp, short oral siphon, and 19-segmented female antennule.

  • The problems caused by new biological organisms in Ogasawara Island of Japan include : (1) loss of native species' habitats and extinction of native species due to the multiplication of invasive species; (2) reduction of native species and confusion in the food chain in result of invasive species' predation; (3) confusion in genes due to hybridization of new and native plants; and (4) destruction of ecosystem and erosion of earth due to rapid increase of invasive species. The natural ecosystem of preserved areas in Korea is constantly confused and destroyed by new animals and plants, but Korea does not has any solutions because new animals and plants rarely affect human lives. Invasive species are manually introduced by humans and are considered disasters caused by humans. Korea is in desperate need of campaigns as the general public does not understand the seriousness of the destruction and confusion of natural ecosystem caused by new biological organisms and their indirect/direct influences on humans. It is necessary to evaluate the biological characteristics, ecological influence, and harms of invasive species in preserved areas to establish a system to manage invasive species and plan the priority removal of species that are highly harmful and locally distributed. Manual removal and suppression of new biological organisms that cause problems is effective, but it takes cost, effort, and time. Therefore, we would need to research and develop the most efficient and effective techniques and measures to manage invasive species in our ecosystem.
