Nauplii and cyprid la%ae were cultured in the laboratory at a temperature of 25'c of 33 parts per thousand. La%al development includes the six nauplius and a cyprn'dstages. Morphological characteristics such as antennules, antennae and mandibles as well as the general pattern of the thoracican Cirripedia are described and illustrated. All the nauplius larvae have trilobed labra which are typical in balanoides, with numerous slender hairs. It is possible to compare the setation of larva of Balanus kondakoui with those of B. albicostatus, B. amphitrr'te, 9. trigonus, B. uariegatus, and Chthamafus rhallengerl' by plotting of numerical setation of the antennae against the mandibles.

Mites in the family Veigaiidae, order Mesostigmata, subclass Acari are widely distributed in subsoil habitats. They are mostly free-living and predaceous on small arthropod eggs and larvae, and prefer habitats with rich organic matters including litter and humus layers of forest soil. The genus Veigaia Oudemans, 1905 of the family Veigaiidae (Acari: Mesostigmata) is one of the ubiquitous genera from the Holarctic Region. Until now, only two genera and five species of the family were recorded from Korea. Here we provide a report of the species Veigaia tibbetsi Farrier, 1957 with detailed redescription. Even though V. tibbetsi had appeared in some ecological literature, this is the first record of this species in Republic of Korea. This species was mostly found from pine forest(Pinus densiflora) of northeastern mountainous parts of the Korean Peninsula, in Gangwon and Gyeongbuk Provinces. We provided some ecological characteristics of the family Veigaiidae, which will help to further exploration of acarine biodiversity.

The larvae of Scyra acutifrons are described and illustrated for the first time. The larval stage consists of two zoeal and a megalopal stages. The zoea of S. acutifrons is compared with those of other known species of the Epialtidae from the northern Pacific. The zoea of Scyra acutifrons can be easily distinguished from that of S. compressipes by having a longer rostral carapace spine and an endopod of maxillule with three setae. It is found that the genus Scyra (Pisinae) shows a great similarity to Pisoides bidentatus (Pisinae) and the genus Pugettia (Epialtinae) in the family Epialtidae; especially, S. acutidens coincides well with two Pugettia species (Pugettia incisa and P. gracilis) in the characteristics of the zoeal mouthpart appendages. To facilitate the study of plankton-collected material, a provisional key to the known zoeae of the Epialtidae from the northern Pacific is provided.

While surveying the diversity of fungi of the order Mucorales, two isolates, EML-PUKI12-1 and EML-PUKI06-1, were obtained from the gut of soldier fly larvae inhabiting the bulrush at a pond located in the Chonnam National University Arboretum, Gwangju, Korea. The isolates were confirmed as Mucor irregularis and Mucor fragilis species, respectively, based on the morphological characteristics and phylogenetic analysis of rDNA internal transcribed spacer region. Such mucoralean species belonging to undiscovered taxa has not previously been described in Korea.

The genus Teloganopsis Ulmer belonging to the family Ephemerellidae is only known from the species of T. punctisetae (Matsumura, 1931) in the Korean Peninsula. The members of the genus Teloganopsis are characterized by the following characteristics: head and abdominal tergites without any tubercles and complex setae; forefemur with a row of long and stout setae perpendicularly; maxilla covered with dense setae. A total of 17 species had been previously recorded in this family. Here, Teloganopsis chinoi (Gose, 1980), is newly recorded in Korea which was found under a large stone in Kyeongho river. Larval habitus, habitat, line-drawings of key characters of the species, a checklist with habitus photos of Korean Ephemerellidae, and a key to the larvae of Korean Teloganopsis are provided.

During a survey of fungal diversity in insect guts in Korea, two fungal strains, EML-PGH2 and EML-PUKI88, were isolated from the gut of grasshopper and soldier fly larvae inhabiting the bulrush plants at a pond located in the Chonnam National University Arboretum, Gwangju, Korea. Based on their morphological characteristics and a phylogenetic analysis of the internal transcribed spacer (ITS1 and ITS2) and 5.8S rDNA sequences, the strains were identified as Blakeslea trispora. To our knowledge, the zygomycete species B. trispora has not been previously described in Korea.

An ovigerous hair crab, Telmessus acutidens, was collected in South Korean waters and its larvae were reared in the laboratory. The larval development consists of four zoeal (including an extra zoeal stage) and one megalopal stages. Four zoeal stages are described and illustrated in detail. The zoeas of the present material show some differences from Kurata (1963)'s plankton-collected zoea of T. acutidens in the characteristics of the carapace spines, an endopod and an exopod of the antenna, and the posterolateral process of the abdominal somite. Kurata's zoea agreed well with that of T. cheiragonus. So, it is suggested that Kurata's zoea may be the second zoea of T. cheiragonus.

실험실에서 부화한 Nitocra spinipes Boeck, 1865의 유생을 수온 2$0^{\circ}C$, 염분농도 33.3$\textperthousand$에서 사육하고 그 유생발생단계를 자세히 기술 및 도시 하였다. 본 종은 6개의 nauplius 유생기를 가지며, 부화후 8-10일후에 copepo양 1기가 되었다. 이 종의 유생기는 제1작은 턱다리, 가슴다리의 발생시기, 그리고 caudal setae의 수 등의 특징에 따라 구별되었다. 또한 이미 연구된 Harpacticoida 내의 유생의 제 2, 3촉각의 외지의 체절을 비교하여과 수준에서의 특징을 밝혔다.

Ovigerous crabs of Erimacrus isenbeckii were collected from the northeastern coast of South Korea and their larvae were reared in the laboratory. Two zoeal stages were described and illustrated in detail. The first zoeal characteristics between the present material and Sasaki and Mihara's (1993: J Crust Biol. 13:511 522) were different especially in the setations of the endopods of the maxillipeds. The zoea of Erimacrus isenbeckii strongly resembled those of two Telmessus species in the Cheiragonidae, but the former could be distinguished from the latter by having spinulate carapace spines, a lateral process on the abdominal somite 3, and longer lateral spines on the telson fork.

The purpose of study is to identify trophic pathways from organic matter to macroinvertebrates in terms of the consumer and to characterize the food webs in an intermittent stream system of the Echi River in Japan. The ${\delta}^{13}C$ values of macroinvertebrates and their potential food sources indicated the scraper (Psephenoides spp., Ecdyonurus levis) and collector-gatherer (Ephemera strigata, Paraleptonphlebia chocolata) feed on periphyton and POM (particulate organic matter) in situ. Davidius lunatus, and Hexatoma spp., which were identified as predators, may feed upon Ephemera strigata and Stenelmis larvae, respectively. At station characterized by seepage water, the ${\delta}^{15}N$ values of Ecdyonurus levis, Lymnaea auricularia, and Rhyacophila nigrocephala larva probably showed relatively lower values according to its diets. Even in homogenous species, the trophic pathways of macroinvertebrates in situ exhibited considerable variation; this reflected the trophic pathways from organic matter to the consumer depending on habitat characteristics in stream.
