Two specimens of Chromis albicauda were collected from Jeju Island, Korea. The species is most similar to C. analis, but is distinguishable by the presence of a white caudal fin when alive, 4-5 scale rows on the anterior portion of the preorbital, and a blackish blotch around anal opening. The results of a molecular analysis based on mitochondrial DNA 16S rRNA sequences confirm that the two individuals are not C. analis but C. albicauda as the genetic distance between the two species is 0.044. A comparison of the two individuals of C. albicauda with yellow chromis shows that none of the previously reported yellow chromis is C. analis, but rather they are C. albicauda. Herein, we suggest the new Korean name "Huin-ggo-ri-no-rang-ja-ri-dom" for C. albicauda.

Euryalid specimens were collected from Gonghyeonjin and Daejin, Gangwon-do in the East Sea, Korea at a depth of 250-300 m by fishing nets on November 2013 and August 2014. They were identified as Gorgonocephalus arcticus Leach, 1819 belonging to family Gorgonocephalidae of order Euryalida, which was new to the Korean fauna. Nucleotide sequences of partial mitochondrial cytochrome c oxidase I (mt-COI) gene, which was 569 bp in length, were compared among four Gorgonocephalus species, and were subsequently employed to reconstruct phylogenetic trees using the MP, ML, and BI methods. As a result, no sequence difference was found between the G. arcticus mt-COI gene sequences from Korea and Canada, and the two made a strong monophyletic group. With the newly recorded G. arcticus in Korea, in total, four Gorgonocephalus species have been reported in Korea.

Collections of Gymnopus sect. Levipedes from the Republic of Korea have been studied. Two new species, Gymnopus dryophiloides and G. brunneodiscus, are described based on their macro- and micromorphological and phylogenetic characteristics. Three other species, referred to as Gymnopus spp. 1, 2, and 3, are distinguished as separate taxa without formal descriptions. Taxonomic and phylogenetic positions of all taxa have been inferred and confirmed by analyses of ITS and LSU sequence data. Their detailed descriptions, illustrations and an identification key are provided.

Random amplified polymorphic DAN markers were characterized for three taxonomically problematic Penicillium species : P. aurantiogriseum var. Aurantiogriseum, P. verrucosum and P. puberulum, as well as for 25 species of mono, bi-, and terverticillate Penicillia. The relationships among mono, bi-, and terverticillate Penicillium species were determined from these RAPD markers. Eight species from mono-, eight from bi-, and nine from terverticilate Penicillia were examined. With 14 randomly chosen 10-mer primes, a 310 character by 25 species matrix was generated. Phenetic analysis separated the 25 species into three genetically distinct groups that correspond to the different arrangements of penicilli (mono-, bi-, and terverticillate). The results of this study suggest that P. aurantiogriseum var. aurantiogriseum, P. VERRUCOSUM, AND P. puberulum represent genetically distinct species, and that P. vulpinum should be included in terverticilate Penicillia. Phenogram branching patterns indicated that biverticillate species are genetically more similar to monoverticilate species than they are to terverticillate species.

The genus Prionchulus Cobb, 1916 represents a group of predaceous nematodes belonging to the family Mononchidae Chitwood, 1937, and is found worldwide. However, only five species have been reported thus far from Korea. Prionchulus oleksandri Winiszewska and Susulovsky, 2003 is reported for the first time from Korea, from sediments collected from the Nakdong River. This species is distinguished from other Prionchulus species by its truncated lip region with small cephalic papillae and refringens vaginae. In this study, morphological characters(detailed morphometrics) of P. oleksandri are described and illustrated using optical microscopy. DNA barcode sequence information (the D2-D3 region of 28S rDNA, 18S rDNA, and internal transcribed spacer rDNA) is also provided for the molecular identification of the species.

A spionid polychaete, Boccardiella hamata (Webster, 1879) has been found from mud in crevices between the shells of oysters and adherent substrates in South Korea. The sequences of mitochondrial DNA (mtDNA) cytochrome c oxidase subunit 1 (CO1), 16S ribosomal DNA (16S), and the nuclear 18S ribosomal DNA (18S) from Korean individuals of Boccardiella hamata were determined in the present study. The molecular analysis based on the 18S rRNA gene sequences showed clear separation among the spionid polychaete species, and the sequences of Korean and Japanese individuals are completely identical. The morphological diagnosis and photographs of B. hamata are also provided.

In this study, cytochrome c oxidase subunit I(COI) sequences of 17 individuals from six Korean diogenid species(i.e., 2 Areopaguristes japonicus, 4 A. nigroapiculus, 3 Paguristes digitalis, 4 P. ortmanni, 3 Diogenes edwardsii, and 1 Ciliopagurus kempfi) were determined and analyzed. The DNA barcoding results of this study were consistent with the morphological identification of these six species. Interspecific variations of COI sequences within six Korean diogenid species exceeded the minimum interspecific variation of diogenid hermit crabs in previous studies. Little intraspecific variation exists except for P. digitalis. This study should facilitate further molecular taxonomy of East Asian diogenids.
