  • Lyngbya C. Agardh ex Gomont is a nonheterocytous cyanobacterial genus whose evolutionary history is still poorly known. The traditionally defined Lyngbya has been demonstrated to be polyphyletic, including at least five distinct clades, some of which have been proposed as new genera. Intraspecific diversity is also clearly underestimated in Lyngbya due to the lack of unique morphological characters to differentiate species. In this study, we describe the new genus Capillus T. A. Caires, C. L. Sant'Anna et J. M. C. Nunes from benthic marine environments, including two new Brazilian species (here described as C. salinus T. A. Caires, C. L. Sant'Anna et J. M. C. Nunes, and C. tropicalis T. A. Caires, C. L. Sant'Anna et J. M. C. Nunes), and two species yet to be described, one of them from India (Capillus sp. 2.1), and the other from United States of America, based on strain PCC 7419. Capillus species presented cross-wise diagonal fragmentation, assisted or not by necridic cells, which has not been previously mentioned for Lyngbya. Ultrastructural analyses showed that C. salinus and C. tropicalis have numerous gas vesicles, which are rarely described for benthic marine species. The new genus formed a well-supported clade, and the D1-D1' and Box B secondary structures of internal transcribed spacer also supported the proposal of its new species. These findings help to clarify the diversity of species in the Lyngbya complex and the taxonomy of the group, and highlight the need of further floristic surveys in tropical coastal environments, which remain poorly studied.

  • A genuine interstitial cyclopoid species belonging to the genus Psammophilocyclops Fryer, 1956 is recorded from the filtration basin of a water treatment plant, South Korea. The genus Psammophilocyclops is very rarely found, and only three species have been recognized as yet: P. boccaroi Fryer, 1956 from Africa, P. trispinosus Shen et Tai, 1964 and P. bispinosus Shen et Tai, 1964 from China. The present new species differs from the congeneric species by the character combination of 11-segmented antennule in female, four-segmented maxilliped with 2,1,1,2 setation, the spine formula of 3,3,3,3, and setal arrangement of 3,3,5,3 on the distal endopodal segments of legs 1-4. Descriptio and taxonomic accounts of the new species are presented with a revised generic diagnosis and a key to the species hitherto known in the genus.

  • The genus Krenosmittia is a small group of Orthocladiinae, containing a total of twenty species in the world. Among them, six species were found in Japan, four species in China, and five species from the Russian Far East. This genus can be distinguished from other Orthocladiinae genera by the eyes bare, absence of acrostichals on thorax, costa strongly extended, anal vein ending proximal to FCu, squama bare, and having a strongly developed virga. We report three new species: K. danyangensis n. sp., K. triangulia n. sp., and K. pseudoannulata. The genus Krenosmittia is the first record in Korea. Line drawings of the diagnostic characters are provided for all the species recognized in this study.

  • A new sponge species of the genus Hymeniacidon (family Halichondriidae) from Munsum, Jeju Island, Korea is described. This species is similar to H. sinapium in spicule size, but the color, oscules, external surface and arrangement of the spicules are considerably different. This species is bright yellow in live, and retains multiple oscules and a plumose bundle of styles in the subectosomal region.

  • A new species, Venturia tenuiabdominalis Choi sp. nov., belonging to the subfamily Campopleginae, family Ichneumonidae, is described in South Korea. The subfamily Campopleginae was recorded by Forster in 1869 based on genus Campoplex and more than 2,100 described species into 66 genera have been reported worldwide. Among the 66 genera of Campopleginae, the genus Venturia is one of the large groups, which is more than 140 species worldwide (Yu et al., 2016; Vas, 2019a; 2019b; Vas, 2020; Vas and Di Giovanni, 2020; Han et al., 2021). A taxonomic study of South Korean Venturia was initiated by Choi et al. (2012), who reported Venturia longipropodeum (Uchida, 1942). A key to species of South Korean Venturia, description of new species and diagnostic illustrations are provided.

  • Catiniidae과의 모식속이자 모식종이며 불완전하게 기록된 Catinia plana Bocquet and Stock을 모식 표본의 재조사를 통하여 재기재 하였다. 부속지의 구조, 특히 대악과 제2소악의 구조를 재해석하였다. 이와 함께, 동일 과에 속하며 지금까지 단형속이었던 Myzomolgus속의 2신종을 기재하였다. 이들은 각각 한국산 성구동물 Sipunculus nudus Linnaeus와 Siphonosoma cumanense (Keferstein)의 피부에 공생한다. Myzomolgus속의 종들을 비교한 결과, 이들은 여러 가지 동질적인 형태를 공유하고 있으며, 따라서 이 속은 확실한 속임이 판명되었다. Catiniidae과의 5속을 식별하는데 이용되는 검색표도 제시하였다.
