  • On 28 April 2008, a male Himalayan Swiftlet (Aerodramus brevirostris) was captured and examined at a night roost of swallows on Hongdo Island, Jeollanam-do, Korea. This is the first record of this species from Korea confirmed by specimen examination. We describe morphological features and some phylogenetic notes of the Himalayan Swiftlet found.

  • Aphelenchoides nonveilleri $Andr{\acute{a}}ssy$, 1959, belonging to the family Aphelenchoididae Skarbilovich, 1947, is first reported from South Korea. The genus Aphelenchoides Fischer, 1894 includes about 200 species worldwide, but to date only nine Aphelnechoides species have been reported from South Korea. Specimens of A. nonveilleri were collected from the roots and shoot tips of chrysanthemum (Chrysanthemum morifolium Ramat, 1792) from a greenhouse. This species is distinguished from other Aphelenchoides species by its star-shaped mucro on the female tail tip, three lateral incisures, and the length of the post-vulvar uterine sac. Here we provide details of the morphological characters and morpometrics of A. nonveilleri based on optical microscopy.

  • Cephalobus aff. quinilineatus (Shavrov, 1968) Anderson and Hooper, 1970 and Eucephalobus hooperi MarinariPalmisano, 1967 from the family Cephalobidae Filipjev, 1934 (Cephalobomorpha) are newly reported from South Korea. Cephalobus aff. quinilineatus is distinguished from other Cephalobus species by its high and rounded labial probolae and five lateral incisures, with three incisures extending to the tail terminus. Eucephalobus hooperi is distinguished from other Eucephalobus species by its three bifurcated labial probolae with pointed termini and by morphometric characters such as body and tail length and the corpus:isthmus ratio. In this study, the morphological characters and morphometrics of C. aff. quinilineatus and E. hooperi Korean population are described and illustrated based on optical and/or scanning electron microscopy.

  • 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.

  • Recently, the new genus Parkiana (Lecithoceridae) and its two new species, Parkiana matutinalis and Parkiana andasibensis, were described by the authors from Andasibe, Madagascar. Although the morphological descriptions and figures fully characterized the new genus with two new species in that paper, the journal issue in which the description appeared was published online-only, and the ZooBank LSID, required for validation of new names in electronic-only publications, was not included. Therefore, the present note serves to validate the names of the new genus and species, Parkiana, Parkiana matutinalis and Parkiana andasibensis, by fulfilling Code conditions for nomenclatural availability.

  • The aim of this study is to report monotypic species, Nonparahalosydna pleiolepis(Marenzeller, 1879) for the first time from Korean waters with its DNA barcoding data. We collected individuals of the species from the subtidal zone of southern coast of Korea through scuba diving. To estimate DNA barcoding gap, the pairwise genetic distances were calculated between N. pleiolepis and its congeners (Halosydna brevisetosa Kinberg, 1856 and Lepidonotus squamatus (Linnaeus, 1758)) based on the cytochrome c oxidase subunit I gene (COI). Inter-specific genetic distances ranged from 18.7% to 24.6%, while intra-specific genetic distance within N. pleiolepis ranged from 0.3% to 0.5%. The maximum intra-specific genetic distance among the three species was 1.4%. The morphological diagnosis of N. pleiolepis with a taxonomic note on the species were also provided.

  • In this study, we identified three monogonont rotifers from South Korea: Kellicottia bostoniensis (Rousselet, 1908), Trichocerca tenuior (Gosse, 1886), and Lepadella triptera (Ehrenberg, 1830). The distribution records of K. bostoniensis were mainly located in the Nearctic, Neotropic and Western Palearctic regions. After Japan, this is the second record of it in Asia. Trichocerca tenuior and Lepadella triptera have already been recorded in Korea, but the data of two species were insufficient in previous study. Here, we describe the morphological characteristics of the three species and the trophi structures of K. bostoniensis and T. tenuior. This study is the first to characterize the trophi structure of K. bostoniensis, observed using a scanning electron microscope. In addition, we have determined the partial cytochrome c oxidase subunit 1 (COI) and 18S rRNA gene sequences of T. tenuior and L. triptera for their DNA barcodes.

  • 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.

  • 한국산 담수 물벼룩류는 지금까지 41종이 기록되어있고 분류학적인 연구는 매우 미흡하다. 따라서 재료 동정을 용이하게 할 수 있는 자료가 없는 실정인데 저자는 이 문제를 해결하기 위해 검색표를 만들었다. 본 검색표에는 한국 담수산 물벼룩류 53종이 수록되어 있는데 저자가 직접 관찰한 종은 11종의 한국내 미기록종을 포함하여 42종으로서, 재료는 1978년 부터 1986년 사이에 한국 전역에서 채집된 것들이다. 저자가 관찰하지 못한 11종을 제외한 42종은 모두 특정적인 부위를 그림으로 묘사했다.
