Two new marine sponges, Clathria(Clthria) gimnyeoungenesis n. sp. and Clathria(Clthria) reticularis n. sp., were collected in Jejudo Island, Korea by fishing nets in September 1994. C.(C.) gimnyeoungenesis n. sp. is closely related to C.(C.) toxipraedita Topsent, 1913 based on spicule types, but are different in the size of spicules and growth forms. Especially, the thick styles and large toxas length of this species are half of C.(C.) toxipraedita. Growth form of the new species is branched but massive encrusting in C.(C.) toxipraedita. C.(C.) reticularis n. sp. is similar to C.(C.) compressa Schmidt, 1862 based on spicule types, but are different in the size of spicules. Especially, large toxas of this new species is twice as long as C.(C.) compressa and they have large isochelae, which are absent in the latter.

Two new species of the family Spongiidae, Spongia (Heterofibria) cora/lina n. sp. and Spongia (Heterofibria) purpurea n. sp. are described. They were collected from Gageodo Island, Jeollanam-do, Korea. Spongia (H.) coral/ina n. sp. is closest to S. (H.) cristata Cook & Bergquist (2001) from New Zealand in skeletal features, but the new species differs from S. (H.) cristata by the arrangement of fibres and growth form. Spongia (H.) purpurea n. sp. closley resembles S. (H.) cristata, but the new species differs from New Zealand specimens by the arragement and thickness of pseudo-tertiary fibres.

The hornless Australian burrowing mayfly genus Ulmerophlebia Demoulin (Leptophlebiidae) is revised based on comprehensive examinations of adult and larval material collected throughout Australia. Two new species [Ulmerophlebia deani n. sp. and U. minuta n. sp.] and three named species [U. annulata (Harker), U. mjobergi (Ulmer) and U. pipinna Suter] are included. The larva of U. deani can be distinguished by the moderately developed apicomedial expansion of gills and W-shaped markings on the abdominal terga. The male adult of U. minuta can be easily distinguished by the greatly reduced penes. Descriptions, diagnoses, line-drawings of key characters, material and distributional data, taxonomic remarks and adult and larval keys are provided.

This study on Pemphigidae was based on the specimens collected from May 1989 to April 1993, at 16 localities of southern part of Korean Penninsula. As a result, 11 species of 7 genera were identified. Of these, four species (Colophina zelkovae, Prociphilus chaenomelis, Tetraneura pumilae, T. iriensis) are new to science. These four species were described and drawn.

Two new marine sponges in family Halichondriidae, Halichondria ulleungensis n. sp. and H. hongdoenesis n. sp. are collected from Ulleungdo Island and Hongdo Island, Korea by SCUBA diving during 2003-2004. H. ulleungensis n. sp. is similar to H. corrugata Diaz, Pomponi and van Soest, 1993 in the type of spicule, but it is different in growth form and choanosomal skeleton. The growth form is encrusting, with numerous erected cylindrical tube, comparing with massive-lobate of H. corrugata. The choanosomal skeleton is confused with loosely arranged oxea tract, comparing with densely tracts with many spicules of H. corrugata. H. hongdoenesis n. sp. is similar to H. surrubicunda Hoshino, 1981 in type of spicule and growth form, but this species has two kinds (thick and thin) of oxea.

A study on marine sponges was conducted with the materials collected by SCUBA diving in Hongdo and Gageodo Islands, Korea from September 2004 to July 2005. Clathria (Clathria) hongdoensis n. sp. and Clathria (Clathria) sohuksanensis n. sp. turned out to be new to the science. Clathria (Clathria) hongdoensis n. sp. closely seems to C. (C.) acanthstyli Hoshino (1981), based on their spicules type. However, they differ in the size of spicules and growth form. Clathria (Clathria) sohuksanensis n. sp. is similar to C. (C.) bicalthrata Hooper (1996), except for lacking small toxas.

This study deals with three microcoryphian species in two genera, including two new species Pedetotus longus n.sp. and Haslundichilis viridis n.sp., and one species of new record for South Korea Pedetontus unimaculatus Machida, 1980 . four species in two genera are accordingly listed for the microcoryphian fauna of Korea.

As a result of this report, the pseudoscorpion family Chthoniidae in Korea comprises nine species in four genera. All species are collected mainly from the litter layer in wooded forests. The two new species, Tyrannochthonius suppressalis n. sp. and Tyrannochthonius spinatus n. sp., described herein occur on islands in the Yellow Sea.

A new marine sponges, Mycale (Carmia) ieoensis n. sp., of the family Mycalidae was collected SCUBA diving in June 2017 from Ieodo Ocean Research Station, Korea. M. (C.) ieoensis n. sp. is encrusting to irregular massive type, yellow in life. This new species is similar to M. nullarosette Hoshino, 1981 in color and growth form but it differs in spicule size and sigma shape. Spicule size of M. (C.) ieoensis n. sp. smaller than that M. nullarosette. Also, M. (C.) ieoensis n. sp. has two size toxa, but M. nullarosette is not. The new species are compared to other Mycale species from the Korean region, and similar species from elsewhere.
