Four species of squat lobsters were collected off the northwestern coast of the Baja California Peninsula, Mexico, during an exploratory survey of fishing resources. Janethogalathea californiensis, described from California was previously known from off the west coast of the Baja California Peninsula (two localities) and from the Gulf of California (three localities). Of the three species of Munida collected during the survey, M. tenella is recorded off the west coast of the Baja California Peninsula for the first time. These are the fourth record of M. hispida and the second record of M. quadrispina in western Mexico.

Abstract The Stomatopoda of Korea have, in general, been poorly studied, with eight species recorded to date. A recent study of stomatopods collected by SCUBA diving and commercial fishing trawlers from Korean waters, however, resulted in the discovery of first records of six species from the study area. Among them, four belong to the superfamily Squilloidea Latreille, 1802 [Levisquilla inermis (Manning, 1965), Levisquilla jurichi (Makarov, 1979), Anchisquilla fasciata (De Haan, 1844), and Cloridopsis scorpio (Latreille, 1828)], and two belong to the Lysiosquilloidea Giesbrecht, 1910, one each in Tetrasquillidae Manning & Camp, 1993 [Acaenosquilla latifrons (De Haan, 1844)] and Nannosquillidae Manning, 1980 [Acanthosquilla multifasciata (Wood-Mason, 1895)]. Thus, fourteen species of Stomatopoda are now known from Korea. The superfamily Lysiosquilloidea is reported for the first time from Korean waters. A key to the species of Korean mantis shrimps is provided.

Three amphipods of the family Photidae collected from Korean waters are reported here with detailed descriptions and illustrations. The Korean materials of Gammaropsis examined in this study are readily assigned to G. longipropodi by the characteristic shape of gnathopod 2 in males: not slenderly produced posterior margin of the carpus, uniform width of very elongate propodus, and the transverse palm. Among the species of genus Photis, P. fischmanni is only one species bearing stridulation ridges of the basis on gnathopod 2 and coxa 3 simultaneously in females, until now. However, Photis stridulus sp. nov. also show this characteristic but is clearly distinguishable from P. fischmanni by the weak setation of the appendages, smaller eye on the anterior cephalic lobe, and the slender carpus and propodus on gnathopod 1. The genus Podoceropsis is recorded from Korean waters for the first time with the discovery of P. clavapes sp. nov. This new species is characterized by its elongate propodus and dactylus on gnathopod 2 and the shape of the posterior lobe of the basis on pereopod 5 in mature males.

In this paper, seven new species of the family Photidae from Korean waters are described and illustrated in detail. Among them, Exiliphotis petilasp. nov. is a monotype of the newly reported Exiliphotisgen. nov., which is characterized by slenderer and more elongate pereopods 5–7 than those of other genera of the family Photidae. The genus Latigammaropsis is reported for the first time from Korean waters based on the description of Latigammaropsis careocavatasp. nov., which is differentiated from other Gammaropsis group by having weakly sexual dimorphic gnathopods 2, those have simple palmar margins in both sexes. Three new species of Photis are also described: Photis broncasp. nov., Photis posterolobussp. nov., and Photis longicarpussp. nov. The formerly misidentified Photis longicaudata from Japan and China as well as the Korean material could be classified as a new species, P. broncasp. nov. For that, the syntypes of P. longicaudata were re-examined, and lectotype and paralectotypes were newly designated in this study. Photis broncasp. nov. is characterized by quadrate tooth on the palmar margin medially on gnathopod 2 in both sexes. Photis posterolobussp. nov. shows a pointed posterior lobe on the ischium and a well-developed process of the propodus on male gnathopod 2. Photis longicarpussp. nov. can be distinguished from other species of the genus by very elongate carpus of male gnathopod 1. Two new species belonging to the genus Podoceropsis are also reported: Podoceropsis insinuomanussp. nov. has a strongly bisinuous palmar margin on male gnathopod 2, and Podoceropsis pseudoclavapessp. nov. differs from the closely related species of Podoceropsis clavapes by different shape of the palmar margin and shorter dactylus of male gnathopod 2. Additionally, a key to the Korean species of Photidae is provided.

The present study describes five newly recorded modern benthic foraminiferal species from the subtidal zone near Jeju Island and East China Sea (Korea). The newly recorded species (Karrerulina conversa, Rotaliammina trumbulli, Vertebralina striata, Pegidia dubia and Amphistegina radiata) belong to five families (Prolixoplectidae, Trochamminidae, Fischerinidae, Pegidiidae and Amphisteginidae), three orders (Lituolida, Miliolida and Rotaliida) and two classes (Globothalamea and Tubothalamea). All these five genera (Karrerulina, Rotaliammina, Vertebralina, Pegidia and Amphistegina) were also reported for the first time from Korean waters. Most of the examined specimens were highly consistent morphologically with previous records from southern China and Japan. Additionally, Amphistegina is one of the symbiont-bearing larger benthic foraminifera, known to be mainly distributed in tropical to warm subtropical waters. This study contributes to the expansion of data on the recent foraminiferal species diversity in Korean waters.

The enchytraeid fauna of Mt. Hallasan (Jeju Island, Korea) was studied in 2016, and 21 enchytraeid species were recorded and identified in total. A combination of morphological and molecular analyses (based on CO1, ITS and H3 sequences) was applied. Here we give descriptions of eight new species of Enchytraeidae (Clitellata): Achaeta koreana sp. n., Achaeta macroampullacea sp. n., Bryodrilus hallasanensis sp. n., Chamaedrilus baekrokdamensis sp. n., Enchytronia seongpanakiensis sp. n., Mesenchytraeus jungsaihoi sp. n., Xetadrilus jejuensis sp. n. and Xetadrilus aphanoides sp. n. Additionally, two species were found to be new for the Korean fauna in Mt. Hallasan: Fridericia cf. paroniana Issel, 1904 and F. perrieri (Vejdovský, 1878); three potentially new Fridericia species require further studies. Furthermore, two terrestrial polychaetes, Hrabeiella periglandulata Pižl & Chalupský, 1984 and Parergodrilus heideri Resisinger, 1925, were recorded. For 12 enchytraeid species, DNA sequences are presented for the first time: these include, apart from the new species, further taxa such as species of Xetadrilus, a genus of which no sequences were previously available.

Two species of the chirostyloid families Sternostylidae and Eumunididae, Sternostylus investigatoris (Alcock & Anderson, 1899) and Eumunida balteipes n. sp., are reported on the basis of material collected from deep waters off Kume Island, Ryukyu Islands, southwestern Japan. Sternostylus investigatoris is recorded for the first time and is the second species of the genus from Japanese waters. Eumunida balteipes n. sp. is morphologically closest to E. sternomaculata de Saint Laurent & Macpherson, 1990, but the armature of the thoracic sternite 3 and P1 palm distinguishes the two species.
