After the revision of the Korean species of Asthena $H{\ddot{u}}bner$, we additionally added one new species, Asthena koreana sp. nov. and two new records, Asthena hamadryas Inoue and Asthena sachalinensis (Matsumura) from Korea. Asthena koreana sp. nov. can be characterized by the white forewing with a costally bifurcated, loop-shaped antemedial line, black minute discoidal dot and single postmedial line and white hindwing with straight antemedial line and black discoidal dot. Asthena hamadryas Inoue can be distinguished by a white forewing with a costally loop-shaped antemedial line and undulating, double lines of the postmedial line, as well as a white hindwing with four light ochreous waved lines without discoidal dots. Asthena sachalinensis can be distinguished by their whitish forewing with thick light brownish postmedial lines and minute black discoidal dot on the costal loop of the antemedial line and whitish hindwing with light brownish medial lines with minute black discoidal dot. Currently, eight species of the genus are known in Korea. We provided a revised key to the Korean species of the genus.

Background: Many investigations on phytoplankton from the Nakdong River carried out. However, since the weirs were constructed, only changes in phytoplankton biomass and dominant species have been restrictively studied in phytoplankton investigations in the Nakdong River. Added to this, any investigation on the phytoplankton flora has not been done in the Nakdong River. The aim of this study is to elucidate the characteristics of phytoplankton communities in the Nakdong River with the weirs built in it. Results: We observed a total of 103 taxa of Euglenophytes belonging to 8 genera from middle-lower part of the Nakdong River. The genus Trachelomonas was the most abundant group making up 40 taxa, followed Lepocinclis (20), Phacus (17), Strombomonas (14), Euglena (5), Colacium (3), Monomorphina (3) and Menoideum (1). Among them, a total of 22 taxa including Colacium (1), Lepocinclis (8), Phacus (4), Strombomonas (4) and Trachelomonas (5) were reported for the first time in Korea, and 86 taxa including those new to Korea were first recorded in the Nakdong River. All the species are illustrated with photomicrographs, and new to Korean species briefly discussed with regard to their taxonomy together with photomicrographs. Conclusions: The present study, a total of 22 taxa including one species of Colacium, 8 taxa of Lepocinclis, 4 taxa of Phacus, 4 taxa of Strombomonas and 5 taxa of Trachelomonas were reported for the first time in Korea, and 86 taxa including those new to Korea were first recorded in the Nakdong River.

One species of Euteliidae, Targalla delatrix ($Guen{\acute{e}}e$) and two species of Nolidae, Nola miyanoi Sasaki and Nola semiconfusa (Inoue) are reported for the first time in Korea. Targalla delatrix can be distinguished by the dark brownish forewings that show the transverse antemedial line, the costally rounded postmedial line and the bowl shaped marking on the costal part of subtermen and the dark brownish hindwings. Nola miyanoi can be distinguished by the whitish forewings that have the band-shaped central fascia with the blackish undulating antemedial line and the dark brownish undulating postmedial line and the whitish hindwings with a light blackish discal dot. Nola semiconfusa can be distinguished by the light grayish forewings that show deeply indented antemedial line, medially strongly projected and dentate postmedial line, a dark brownish subterminal line and a dark brownish termen, and the whitish hindwings with a light grayish discal dot. Adults and genitalia are illustrated and briefly described with their biological and distributional notes.

The genus Charops is one of the small genera of the subfamily Campopleginae with 30 species reporded worldwide. All of the known host insects of Charops striatus belong to the lepidopteran family Zygaenidae, perceived as harmful. C. striatus, one of the endoparasitoids from Elcysma westwoodi, is the most damaging lepidopteran pest of Prunus yedoensis. In South Korea, host plants of C. striatus were reported by Choi & Lee in 2008. In this paper, two new host plants, Crepidiastrum denticulatum and Zea mays, of Charops striatus are reporded for the first time from South Korea. Digital images and redescription of this species are provided.

The 2015 version of the bibliographic checklist of Korean spiders from the first checklist by Paik and Kim (1956) is presented, together with a complete bibliography of relevant Korean araneological literature. A total of 620 publications during 1907-2015 including original description on the Korean spiders and records of taxonomic description were critically reviewed. Records only from locations within the present borders of South Korea are listed. A total of 748 spider species of 271 genera belonging to 46 families are confirmed to exist in Korea. Twenty one species, whose distribution or existence within the Korean border are uncertain and lacked valid records, are excluded from the present list pending critical validation. Four spider species endemic to North Korean are listed separately from the present list. One genus, Joopilia Chae and Sohn, 2013 and 2 species, Joopilia jooplis Chae and Sohn, 2013 and Dolomedes jirisanensis Kim and Chae, 2012, which had no designated type species and no diagnosis, are cited as nomina nuda. New synonyms of 15 previously described spider species are proposed. Based on their zoogeographical distribution, the Korean spider fauna was found to be influenced by the northern species, including 36 Holarctic and 72 Palearctic species (14.5% of the total species). Korean endemic species include 160 species (21.5% of the total species). Korean indigenous spiders are also distributed in neighboring countries: 318 species in Russia (42.7%), 460 in China (61.7%), and 488 in Japan (65.5%).

During a comprehensive investigation of indigenous prokaryotic species in Korea, a total of 46 bacterial strains assigned to the classes Alphaproteobacteria, Betaproteobacteria, Deltaproteobacteria, and Epsilonproteobacteria were isolated from a diversity of habitats including freshwater, seawater, brackish water, ginseng soil, plant roots, natural caves, and tidal flats. Based on their high 16S rRNA gene sequence similarities (>98.7%) and formation of strongly-supported phylogenetic clades with the closest type species, each strain was assigned to an independent, predefined bacterial species. Since there were no published or official reports regarding the isolation of these 46 species in Korea, here we report them as new species to Korea: 34 species in 14 families in the five orders of Alphaproteobacteria, 10 species in five families in the three orders of Betaproteobacteria, one species of Deltaproteobacteria and one species of Epsilonproteobacteria. Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs are described in the species description section.

Forest tree diversity inventory and its periodical monitoring are important to understand changes in tree population structure and to provide information useful for biodiversity conservation and reserve management. In a long-term forest dynamics program in Indian tropical dry evergreen forest, this communication deals with tree diversity changes at decadal interval. The initial inventory of tree diversity was carried out in 2003, in four tropical dry evergreen forest sites - (much disturbed sites Shanmuganathapuram - SP and Araiyapatti - AP and moderately disturbed sites - Karisakkadu - KR and Maramadakki - MM) on the Coromandel Coast of peninsular India, by establishing four 1ha permanent plots, one in each site. In 2013, the four plots were re-inventoried for tree diversity (${\geq}10cm\;gbh$) changes which yielded 56 species from 46 genera and 26 families. The studied forest sites are threatened by disturbance due to multiple reasons; cutting of trees inside of the forest, grazing by goats, construction of temple approach road, and some aspects cultural attachment of local people like constructing new, additional strctures of temple by denuding a portion of forest etc.. Tree species richness over a decade increased by four species in site SP, two species in site AP, and one species in site KR, but decreased by one species in site MM. Tree density decreased drastically by 480 (28.92%) and 102 (12.63%) stems $ha^{-1}$ respectively in sites SP and AP, but moderately increased by 82 (12.09%) stems $ha^{-1}$ in site KR and 26 (3.46%) stems $ha^{-1}$ in site MM. Tree basal area declined in site KR from $21.6m^2$ to $20.26m^2ha^{-1}$ and in site SP from 21.1 to $20.38m^2ha^{-1}$, but increased from $19.1m^2$ to $19.43m^2$ and from 15.5 to $18.63m^2ha^{-1}$ in sites AP and MM respectively. Three tree species (Allophylus serratus, Maytenus emarginata and Ehretia pubescens) were lost out of the 57 species recorded in 2003, and two species (Jatropha gossypiifolia and Streblus asper) were new additions in ten years. The long-term forest monitoring data will be valuable to understand forest dynamics and for conservation and management of this and similar tropical forests.
