  • A new species of the cave-dwelling springtail Lethemurus coreanus Chang and Bae, sp. n. is described from Korea. Lethemurus coreanus can be distinguished from congeners by the spine-like setae on the tibiotarsus, numbers of dental spines, number of setae on the trochanteral organ, and body macrochaetae chaetotaxy. A key to the species of Lethemurus is provided.

  • 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.

  • Two species of the family Porcellidiidae associated with hermit crabs are described from Korean seas. These are Porcellidium similis, new species collected from Pagurus similis, Pagurus pectinatus and Porcellidium brevicaudatum Kicks & Webber collected from Dardanus impressus. The new species resemble closely Porcellidium brevicaudatum in general body form, but is clearly distinguished from Porcellidium vrevicaudatum in that the caudal ramus is weakly oblique in tis distal border and the lobe of leg 5 is more slender.

  • A new cyclopoid species belonging to the genus Acanthocyclops is described from several mountain springs in South Korea. This species is allied to A. kieferi species group in sharing 11-segmented antennules, but is, clearly distinguished from them by its single apical spine on the third endopodal segment of leg 4 and an extra spine on the distal segment of leg 5 in both sexes.

  • Six new species of copepods associated with polychaetes are described from Korea. Included are Indoclausia bipartita n. sp., Clausia parva n. sp., and Maxilliclausia propria n. gen. n. sp. in the Clausiidae; Pseudanthessius excertus n. sp. in the Pseudanthessiidae; and Polyankylis ovilaxa n. sp. and Sewelloya plana n. gen. n. sp. in the Polyankyliidae. The new genus Maxilliclausia has a peculiar maxilla in which the distal segment forms a sucking disk, a non-prehensile antenna, vestigial legs 3 and 5, and lacks a maxilliped and leg 4. The two new species of the Polyankyllidae are discovered as external associates of terebellid polychaetes. The new genus Sewelloya has a simple female maxilliped bearing only two small setae on its terminal segment, an uniramous leg 4 bearing 1-segmented exopod, and a reduced leg 5 represented by three setae. The genera Terebelliphilus Kim, 2001 which was originally placed in the Sabelliphilidae, and Octophiophora Stock, 1988 and Stockia Sebastian and Pillai, 1974, both of the latters with uncertain familial positions, are transferred to the Polyankyliidae. A key to five genera of the Polyankyliidae are provided.

  • Two new species of poecilostomatoid copepods associated with echiurans are described from an intertidal mud flat in the Yellow Sea. A new genus Echiuricopus is created to accommodate two new species, E. aprilis and E. tenuipes. Major differences between the two new species are displayed in body length, length of caudal ramus seta I, length/width ratio of leg 5 exopod, and armature of the first antennular segment. Echiuricopus n. gen. is closely related to the genus Goidelia Embleton, 1901, but is distinguished from the latter chiefly by having seven caudal setae, a claw-like process on the first antennular segment, one claw-like process on the maxillary syncoxa, the absence of an inner coxal seta on legs 1-4, different armatures on legs 1-4, and an elongate leg 5 exopod.

  • To explore species diversity of Hypocreaceae, collections from Guangdong, Hubei, and Tibet of China were examined and two new species and a new Chinese record were discovered. Morphological characteristics and DNA sequence analyses of the ITS, LSU, $EF-1{\alpha}$, and RPB2 regions support their placements in Hypocreaceae and the establishments of the new species. Hypomyces hubeiensis sp. nov. is characterized by occurrence on fruitbody of Agaricus sp., concentric rings formed on MEA medium, verticillium-like conidiophores, subulate phialides, rod-shaped to narrowly ellipsoidal conidia, and absence of chlamydospores. Trichoderma subiculoides sp. nov. is distinguished by effuse to confluent rudimentary stromata lacking of a well-developed flank and not changing color in KOH, subcylindrical asci containing eight ascospores that disarticulate into 16 dimorphic part-ascospores, verticillium-like conidiophores, subcylindrical phialides, and subellipsoidal to rod-shaped conidia. Morphological distinctions between the new species and their close relatives are discussed. Hypomyces orthosporus is found for the first time from China.

  • A total of 121 species of lichens belonging to the genus Arthothelium have been described to date, most of which have been found in tropical regions. Here, we describe the discovery of a novel Arthothelium species for the first time in South Korea. Until now, Arthothelium ruanum was the only Arthothelium species reported in South Korea. Among the 113 specimens collected in this study, we identified A. ruanum and a putative new species, Arthothelium punctatum (J. S. Park & J.-S. Hur, sp. nov.). The diagnostic characters of A. punctatum are as follows: apothecia punctate, shortly elongate to branched, small, 0.1-0.2 mm wide, hypothecium hyaline to pale brown and obovate to broadly ellipsoid, muriform ascospores, $29.5-44.6{\times}12.2-18.2{\mu}m$. The new species was found in Mt. Seokbyeong at an altitude of 790 m on smooth bark. Upon phylogenic analysis, the putative new species, A. punctatum, was separated from other Arthothelium species although the specimens analyzed were clustered with Arthoniaceae in phylogenetic trees based on both the mitochondrial small subunit (mtSSU) sequence and combined mtSSU and nuclear ribosomal large subunit sequences. Our data clearly indicate that this species is a new species belonging to the family Arthoniaceae. To elucidate the taxonomic characteristics of the new species, we provide morphological descriptions and a distribution map.
