As a continuation of part I, this paper deals with the classification of phytoplankton species collected from Chawol-do, Soya-do Pung-do of Kyonggi-Bay. One hundred and fortythree kinds of photoplankton from this area were identified and classified by Engler's system into 17 families, 47 genera, 129 species, 10 varieties and 4 forms, blonging to 2 phyla, 3 classes, 3 subclasses, 8 orders and 1 suborder. 3 families, 7 genera, 10 species, 3 varieties and 3 forms are added. To the list published in part I. Seven species and one form described in this paper are new to Korea.

Twenty nin species of marine bryozoans are reported from Geojedo Island, Korea. Of these, two species, Chaperia acanthina and Antropora tincta are new to Korea fauna, Only two species, Amathia distans and Tricellaria occidentails, included in this paper, were previously recorded from Geojedo Island. Therefore twenty five species of marine bryozoans is newly recorded from Geojedo Island.

We monitored on the hitchhiker insect pests from a total of 112 foreign vessels entering into Korea during 109 days from 1. Jun. to 17. Sep. in 2018. As the results, a total of 336 samples of the hitchhiker insects were collected using simply collecting method by hands, one of interception method and identified as 159 species of 47 families under nine orders on the basis of integrative species identification. Among them, 14 species of nine families under three orders were detected as undistributed species in South Korea. We reported on the 14 undistributed species in South Korea with the data sheets for the risk assessments on invasive or invasive likelihood species. Also, we suggested and used the term 'not-distributed species' for avoiding confusion with 'unrecorded species', 'unreported species', or 'new reported species'.

Three new species of Amynthas (Clitellata: Megascolecidae) were discovered in the Nam Ha National Protected Area (NPA) of Laos. These are Amynthas namhaensis sp. nov., Amynthas vanhi sp. nov., and Amynthas angtanensis sp. nov. Amynthas namhaensis sp. nov. and Amynthas vanhi sp. nov. are athecal, with male pores 0.14-0.17 and 0.17-0.19 circumference apart ventrally, respectively. Amynthas angtanensis sp. nov. has four pairs of spermathecal pores on 4/5-7/8, with male pores very closely set at 0.07-0.1 circumference apart. Descriptions of the new species are provided, including illustrations of the ventral view, intestinal caeca, and spermathecae.

A molecular line survey towards the UC H II region G34.3+0.15 from 155.3 to 165.3GHz has been conducted with the TRAO 14-m radio telescope. Combined with our previous observations from 84.7 to 115.6GHz and 123.5 to 155.3GHz (Paper I), the spectral coverage of this survey in G34.3+0.15 now runs from 85 to 165 GHz. From these latest observations, a total of 18 lines from 6 species were detected. These include four new lines corresponding to ${\Delta}$J = 0, ${\Delta}$K = 1 transitions of the $CH_3OH$ E-type species, and two new lines corresponding to transitions from $SO_2$ and $HC_3N$. These 6 new lines are $CH_3OH$[1(1) - 1(0)E], $CH_3OH$[2(1) - 2(0)E], $CH_3OH$[3(1) - 3(0)E], $CH_3OH$[4(1) - 4(0)E], $SO_2$[14(1, 13) -14(0, 14)] and $HC_3N$[18 -17]. We applied a rotation diagram analysis to derive rotation temperatures and column densities from the methanol transitions detected, and combined with NRAO 12-m data from Slysh et al. 1999. Applying a two-component fit, we find a cold component with temperature 13-16K and column density $3.3-3.4 {\times} 10^{14} cm^{-2}$, and a hot component with temperature 64 - 83K and column density $9.3{\times}10^{14} - 9.7 {\times} 10^{14} cm^{-2}$. On the other hand, applying just a one-component fit yields temperatures in the 47 -62 K range and column densities from $7.5-1.1 {\times} 10^{15} cm^{-2}$.

Some hydroid specimens were collected from 10-14 m deep of Munseom (Jejudo Is.) on 22 June 2007, and from 20-25 m deep of Nagokkkottdongsan (Uljin) on 10 Jan. 2008 by SCUBA diving. Among the identified species, the following three species, Solanderia spinosa (Carter, 1892), Lafoea dumosa (Fleming, 1828) and Rhizocaulus verticillatus (Linnaeus, 1758) were turned out to be new to the Korean fauna.

Molluscan specimens collected in the whole country of Korea during the from 1994 through 2002, were identified and classified. A total of 1,560 molluscan species were listed in this study; one species in class Aplacophora, 18 species in class Polyplacophora, 1,038 species in class Gastropoda, 467 species in class Bivalvia, 14 species in class Scaphopoda and 22 species in class Cephalopoda. Among the identified species, 360 species (three species in class Polyplacophora, 266 species in class Gastropoda, 85 species in class Bivalvia, 6 species in class Scaphopoda) are newly recorded to Korean fauna.

Five new species of the genus Hyattella (Dictyoceratida: Spongiidae); Hyattella chaguiensis n. sp., H. munseomensis n. sp., H. sumsangiensis n. sp., H. bakusi n. sp., and H. purpurea n. sp., were collected from Jeju-do, Korea. Hyattella chaguiensis n. sp. is similar to H. mara Sim and Lee, 2014 in shape, but differs in dermal membrane and primary fibres. Hyattella munseomensis n. sp. differs in cored primary fibres, having middle-size sand. Hyattella sumsangiensis n. sp. is characterized by color changes and very soft texture. Hyattella bakusi n. sp. and H. purpurea n. sp. are similar in shape, having tube-like elevated holes, but differ in skeletal structures.

A revised checklist of Korean Trichoptera is provided for the species recorded from the Korean Peninsula, including both North and South Korea. The checklist includes bibliographic research as well as results after reexamination of some specimens. For each species, we provide the taxonomic literature that examined Korean Trichoptera materials or mentioned significant taxonomic treatments regarding to Korean species. We also provide the records of unnamed species based on larval identification for further study. Based on taxonomic considerations, 20 species among the previously known nominal species in Korea are deleted or synonymized, and three species omitted from the previous lists, Hydropsyche athene Malicky and Chantaramongkol, 2000, H. simulata Mosely, 1942 and Helicopsyche coreana Mey, 1991 are newly added to the checklist. Hydropsyche formosana Ulmer, 1911 is recorded from the Korean Peninsula for the first time by the identification of Hydropsyche KD. In addition, we recognized 14 species of larvae separated with only tentative alphabetic designations. As a result, this new Korean Trichoptera checklist includes 218 currently recognized species in 66 genera and 25 families from the Korean Peninsula.

A study on indigenous diatoms was carried out at 10 sites from May 2014 to December 2016 in marine and freshwater in Korea. Seventeen species of diatoms are new to Korea and they are divided into 3 classes, 4 subclasses, 10 orders, 14 families, and 16 genera. The nomenclatures, references, dimensions, specimens examined, local habitat, distribution in Korea, and photograph are reported here. Seventeen species found in marine, freshwater, and brackish water showed species-specific habitats.
