Two new Hydropsychidae (Insecta: Trichoptera) species from the Philippines are described. Hydropsyche philippinensis, n. sp., differs from other congeners in the structure of the phallic apparatus. Diplectrona lagunensis, n. sp., can be distinguished from other congeners by its distinct white band pattern in the forewings and by the structure of the phallus. Both new species were collected from a high mountain stream in the northern part of the Philippines. Paratype materials were barcoded to make the sequences readily available in the GenBank.

A new goerid caddisfly, Goera jaewoni n. sp. (Trichoptera: Goeridae), is described from Korea. Larval stages of G. interrogationis Botosaneanu and G. parvula Martynov are also reported for the first time based on reared specimens. Line-drawings of the key characters and taxonomic and ecological notes are provided.

A revised checklist of Korean Trichoptera is provided for the species recorded from the Korean Peninsula, including both North and South Korea. The checklist includes bibliographic research as well as results after reexamination of some specimens. For each species, we provide the taxonomic literature that examined Korean Trichoptera materials or mentioned significant taxonomic treatments regarding to Korean species. We also provide the records of unnamed species based on larval identification for further study. Based on taxonomic considerations, 20 species among the previously known nominal species in Korea are deleted or synonymized, and three species omitted from the previous lists, Hydropsyche athene Malicky and Chantaramongkol, 2000, H. simulata Mosely, 1942 and Helicopsyche coreana Mey, 1991 are newly added to the checklist. Hydropsyche formosana Ulmer, 1911 is recorded from the Korean Peninsula for the first time by the identification of Hydropsyche KD. In addition, we recognized 14 species of larvae separated with only tentative alphabetic designations. As a result, this new Korean Trichoptera checklist includes 218 currently recognized species in 66 genera and 25 families from the Korean Peninsula.

The feeding ecology of endangered Cottus hangiongensis was studied in the Hosan stream from September 2006 to August 2007 by collecting them seasonally. The stomach contents of C. hangiongensis consisted mainly of aquatic insects and Nematoda, small fish, fish eggs, snails (Semisulcospira libertina), and small stones were also observed. The main aquatic insects in the order of relative importance were Diptera, Trichoptera, Ephemeroptera and Plecoptera. The most important prey items were Chironomidae sp.1 and Hydropsyche kozhantschikovi. Change in the main prey organisms by season were Trichoptera in the spring and the summer, Diptera in the autumn, and Plecoptera in the winter by ratio of dry weight.

The authors investigated feeding habit of river sculpin(C. poecilopus) were conducted at the Chiak streams from April 1993 to March 1994. The feeding habit of C. poecilopus was mainly acquatic insects, such as Ephemeroptera, Odonata, Plecoptera, Trichoptera, Coleoptera, Diptera, and Nematoda, teleost fishes, fish egg and terrestrial insects. Terrestrial insects in the stomach contents were found mainly in autumn, and teleost fish(Moroco oxycephalus) was in summer. Aquatic insects(Ephemeroptera, Trichoptera and Diptera) constituted the bulk of food items ingested during each season. The prey selection indices for Ephemeroptera were positively selected in summer, and negatively selected in autumn and winter, Tricoptera and Diptera were positively selected in autumn and winter, and negatively selected in summer. Additionally, analysis for stomach contents of guarding males suggests that the parental males eat their own eggs during egg guarding(filial-cannibalism).

In the family Hydroptilidae, Trichoptera, 11 species in 3 genera, Hydroptila Dalman, 1819, Oxyethira Eaton, 1873 and Stactobia McLachlan, 1880, have been recorded from the Korean Peninsula but, until now, no species in the genus Orthotrichia Eaton, 1873. In this paper, we describe a new Korean species, Orthotrichia coreana sp. nov., based on adult specimens from the middle reaches of rivers in the southern region of the peninsula. This species is similar to O. iriomotensis Ito, 2013 from the southernmost region of Japan, but is clearly discriminated from the latter by features of the male and female genitalia.

We investigated the diel periodicity in the drift in relation to body size by field survey using the fourth instar grazing larvae of Micrasema quadriloba Martynov (Trichoptera, Brachycentridae) as a material. Although the larvae showed nocturnal drift periodicity, drift density in the nighttime was only twice that in the daytime. In both time periods, smaller individuals drifted significantly more, and the drift individuals in the daytime was the smallest in size (P< 0.05 in Sheffe's F). We discussed whether the drift of the fourth instar larvae drift behaviorally or accidentally considering larval size and food depletion.

A historical review of Trichoptera systematics in Korea and diagnoses for 10 newly recorded species of Limnephiloidea are provided: two species, Gumaga orientalis (Martynov) and Ganonema extensum Martynov, are newly recorded from the Korean peninsula, seven species, Goera interrogationis Botosaneanu, G. parvula Martynov, Apatania sinensis Martynov, Ecclisomyia kamtshatica (Martynov), Hydatophylax magnus (Martynov), Goerodes albardanus (Ulmer), and Dinarthrum coreanum (Kumanski and Weaver), and newly recorded from South Korea, and the adult stage of Neophylax ussuriensis (Martynov) is newly recorded from South Korea.

A new limnephilid caddisfly, Nothopsyche bilobata n. sp., is described. The female adult of Apatania martima Ivanov and Levanidova and the larva of Ecclisomyia kamtshatica (Martynov) is newly recorded from Korea. Three undetermined species, Nemotaulius sp. A, Nemotaulius sp. B, and Nothopsyche sp. A, are additionally described.

The larval stage of Ceraclea labulata (Martynov) is described for the first time. The larva can be distinguished from other known larvae of Korean Ceraclea by the absence of head marking and by the shape of frontoclypeus, which is equal in anterior and posterior width. The larval case is also described. Line-drawings of key characters and discussion on Korean Ceraclea are provided.
