  • A single specimen (149.9 mm TL) of sagami grenadier, Ventrifossa garmani was collected from Korea waters. This species is similar to Coelorinchus spp. in body shape, but is distinguished by a short and rounded snout. It is characterized by having the serrated second dorsal spine in the first dorsal fin, a triangular spine on the scale, seven branchiostegal rays and six scales below middle of first dorsal fin. We describe this species as the first record to Korean fish fauna and propose the Korean name "Kkeo-kkeul-meo-ri-min-tae-sok" for this genus, and "Kkeo-kkeul-meo-ri-min-tae" for this species.

  • Two species of small gobiid fishes genus Luciogobius, i.e., L. elongatus, L. platycephalus were described as the first records from Korea based on specimens collected from gravel beaches of Gijang-gun, Busan-si, Korea. Luciogobius elongatus is distinguished from congeners by very elongated and naked body, 42-44 vertebrae, 6-7 dorsal soft rays, and no free rays on pectoral fin, and L. platycephalus is characterized by having very depressed head, naked body, 40-41 vertebrae, 10-11 dorsal soft rays, and pectoral fin with only upper 2-4 free rays. We propose the new Korean name "Ga-neun-mi-kkeun-mang-dug", "Nab-jak-mi-kkeun-mang-dug" for L. elongatus and L. platycephalus, respectively.

  • Two species of Cryptophlebia: C. nota Kawabe and C. ombrodelta (Lower), are reported from Korea for the first time. This is in fact the first record of Cryptophlebia from Korea, as the previous Korean records of the genus were based on one species, Cryptophlebia hematoma Diakonoff, currently assigned to Thaumatotibia Zacher. Photos of the superficial and genital features are provided for the two Korean species of Cryptophlebia and their distribution and host plants are summarized. Cryptophlebia ombrodelta is recognized as an adventive species in Korea and a potential pest on leguminoseous crops.

  • A halacarid species of Scaptognathus teuriensis $Ab{\acute{e}}$ is recorded from Korea on the basis of the specimens collected from littoral sandy sediments at Dokdo Island, the easternmost island off Uleung Island of South Korea. Korean specimens coincide well with the key characters in the original description for types from Hokkaido, Japan, such as male genitoanal plate comprising only pars sclerosum, bipartite female genitoanal plate with six perigenital setae, rounded posterior margin of anterior dorsal plate, second and fifth dorsal setae both positioned at membranous cuticle, leg chaetotaxy of bipectinate setae on tibiae I-IV of 4-2-2-2, and tarsi of all legs armed with paired large lateral claws with accessary teeth and small median claw. Redescription based on Korean specimens and scanning electron microscope photomicrographs are provided herein. This is the first record of the genus from Korea.

Shrink-Wrapped Boundary Face Algorithm for Mesh Reconstruction from Unorganized Points

  • A new mesh reconstruction scheme for approximating a surface from a set of unorganized 3D points is proposed. The proposed method, called a shrink-wrapped boundary face (SWBF) algorithm, produces the final surface by iteratively shrinking the initial mesh generated from the definition of the boundary faces. SWBF surmounts the genus-0 spherical topology restriction of previous shrink-wrapping-based mesh generation techniques and can be applied to any type of surface topology. Furthermore, SWBF is significantly faster than a related algorithm of Jeong and others, as SWBF requires only a local nearest-point-search in the shrinking process. Our experiments show that SWBF is very robust and efficient for surface reconstruction from an unorganized point cloud.

  • The family Olividae includes predatory species with medium-sized, glossy, elongated oval-shaped shell. As sand-dwellers, they are broadly distributed in tropical and subtropical oceans. They feed mostly on other mollusks and carrions including sea snails and bivalves. To date, two species in the genus Amalda (subfamily Ancillinae) have been reported in Korean waters. In this study, Amalda rubiginosa (Swainson, 1823) was collected from Korean waters and morphologically described in details as a first record.
