A Korean Cheiracanthium erraticum (Walckenaer, 1802) is first described with detailed illustrations, leg spination, trichobothrium patterns and SEM photographs of male palp and female epigynum. Two species, C. lascivum Karsch, 1879 and C. eutittha Boesenberg & Strand, 1906 are excluded from Korean fauna. A map showing distribution of species and a key to the species of genus Cheiracanthium from Korea are provided.

A taxonomic study on the genus Nitakra (Ameiridae) is accomplished. A total of five species are collected from coastal marshes, lagoons, and estuaries in South Korea. Among them, the latter three species are newly recorded from Korea: N. spinipes Boeck, N. affinis califarnica Lang and N. pietschmanni (Chappuis). Taxonomic accounts and a key to the species from Korea are given.

The $11{\alpha}$-hydroxylation of $16{\alpha}$, 17-epoxyprogesterone (EP) catalyzed by Rhizopus nigricans is crucial for the steroid industry. However, lower conversion rate of the biohydroxylation restricts its potential industrial application. The $11{\alpha}$-steroid hydroxylase CYP509C12 from R. oryzae were reported to play a crucial role in the $11{\alpha}$-hydroxylation in recombinant fission yeast. In the present study, the CYP509C12 of R. oryzae (RoCYP) was introduced into R. nigricans using the liposome-mediated mycelial transformation. Heterologous expression of RoCYP resulted in increased fungal growth and improved intracellular reactive oxygen species content in R. nigricans. The $H_2O_2$ levels in RoCYP transformants were approximately 2-folder that of the R. nigricans wild type (RnWT) strain, with the superoxide dismutase activities increased approximately 45% and catalase activities decreased approximately 68%. Furthermore, the $11{\alpha}$-hydroxylation rates of EP in RoCYP transformants (C4, C6 and C9) were 39.7%, 38.3% and 38.7%, which were 12.1%, 8.2% and 9.4% higher than the rate of the RnWT strain, respectively. This paper investigated the effect of heterologous expression of RoCYP in R. nigricans, providing an effective genetic method to construct the engineered strains for steroid industry.

The chigger mite Leptotrombidium sialkotense is one of the 6 main vectors of scrub typhus in China. Before present study, L. sialkotense was found in some parts of Hunan province, China with a narrow geographical distribution. During field investigation 2016-2017, we found L. sialkotense in Jingha, southern Yunnan, China. Of 15 small mammal host species, L. sialkotense were collected from 6 species of the hosts. Rattus brunneusculus was a dominant host of L. sialkotense, from which 98.3% of the mites were collected. The chigger mite showed a relatively high infestation prevalence (P_M =11.7%) and mean abundance (MA=0.5) in comparison with the rest 5 host species. These results reveal a certain host specificity of L. sialkotense to a rat R. brunneusculus. The mite L. sialkotense showed an aggregated distribution on the host (P<0.05). A positive correlation observed between L. sialkotense and the body length of hosts. There was a positive interspecific association between L. sialkotense and 2 other dominant vectors, L. deliense and L. scutellare.

The genus Pholcus Walckenaer, 1805 is the largest genus among the cellar spider family Pholcidae C.L. Koch, 1850, including 339 species. To date, 33 species in the genus are known to be distributed in Korea, being placed into three species-groups(crypticolens-group, phalangioides-group, and phungiformes-group). About 91% of these species are endemic to Korea. In this study, four new species of the genus Pholcus were discovered in Korea, viz, Pholcus chuncheonensis Lee, Choi and Kim sp. nov., Pholcus pajuensis Lee, Choi and Kim sp. nov., Pholcus pocheonensis Lee, Choi and Kim sp. nov., and Pholcus unaksanensis Lee, Choi and Kim sp. nov. These new species are classified as members of the phungiformes-group, having morphological characteristics such as male chelicerae with a frontal apophysis, palpal tibia with a prolateroventral tubercle, and genital bulb without appendix or having pseudo-appendix, but can be distinguished from congeners by characteristics of the male palp and female genitalia. Detailed descriptions and a key to new species are provided with accompanying photographs.

Previously, 13 species in six genera of the subfamily Banchinae and 29 speices in 16 genera of the subfamily Pimplinae were known from Korea. In this paper, two species, Rynchobanchus minomensis (Uchida, 1933) and Theronia laevigata nigra Uchida, 1928 are new to Korea. Also, the genus Rynchobanchus is recorded for the first time in Korea. Only one species of Theronia, Theronia atalantae (Poda, 1761), was recorded from Korea by Uchida (1928). New Korean names proposed for these two species are "Eol-gul-ga-si-maep-si-beol" and "Geom-jeong-nap-jak-maep-si-beol" for the R. minomensis and T. laevigata nigra, respectively. A key to the species of Theronia, diagnosis and photographs of diagnostic characters of them are provided.
