The genus Promalctis Meyrick, 1908 is the largest genus of the family Oecophoridae, with more than 150 described species in the world (Wang et al., 2009; Du et al., 2009). The genus is mainly distributed in the Palaearctic and Oriental regions, probably with the highest diversity in the South and East Asia. However it has been very poorly studied to date, with only with only 4 publications which were based on very limited collecting. In total, 76 were reported from China, which is more than half of the known species in the Palaearctic region(Wang, 2006; Du et al., 2009), 14 species known from Korea (Park & Park, 1998), 12 species from Japan (Fujusawa, 2002), 8 species from Russian Far East (Lvovsky, 1976, 1985, 1986), and 3 species from Nepal (Lvovsky, 2000a). In the Oriental region, since Meyrick (1908a, 1908b) described 14 species from India and Myanmar, Lvovsky (2000a, 2000b) described 25 additional species from the southern Asia, including the southern part of China, Malaysia, Indonesia, and the Philippines. In Vietnam, only 4 species, Promalactis albiapicalis Lvovsky 1997, P. buonluoi Lvovsky 1997, P. fansipanella Lvovsky 2007, and P. suzukiella (Matsumura 1931), have been described to date(Lvovsky, 1997, 2007a). The aim of this study is to describe six new species of Promalactis based on material mainly collected in the northern part of Vietnam. Adults, head parts, wing venations, and the male or female genitalia of the new species are illustrated.

The family Tortricidae, with just over 9000 described species (Brown 2005), is the second largest lineage in the microlepidoptera, and by far the most important economically. In Vietnam, de Joanis is the first entomologist has created the original data of moths. From 1928-1929, he reported 45 families belong to Lepidoptera and focoused on Noctuidae and Pyralidae. After the Vietnam war in the North (1954), many times were collected in the North by National Institute of Plant Protection (NIPP). But all of them focused on fauna of the agricultural pests. According to the publication of NIPP (1967-1968), 533 species of 37 families. Recently, Korean entomologists have researched on the Lepidoptera in Vietnam by Park et al. (2007) reported 816 species of Lepidoptera classified by 4 families; Noctuidae (564 species), Pyraloidae (201 species), Sphingidae (28 species), and Lecithoceridae (23 species). Vietnamese entomologists' reports have represented a diversity of Lepidoptera in National parks of Vietnam, but all of them focused on macrolepidoptera. In 2001, one new genus and 6 new species belong into Tortricidae in the Southern part has reported by Kuznetzov. In 2008 Razowski announced 10 Tortricidae species in Vietnam. The main aims of this study are to survey of any references of family Tortricidae in North Vietnam, and it also is the first data about Tortricidae in Vietnam. The materials identification based on the collection of University of Incheon, which has collected from 2004-2007. In the taxonomic review of the Tortricidae in Northern part of Vietnam, 40 species (16 species of the subfamily Tortricinae and 24 species of the subfamily Olethreutinae) are recognized. All of them are reported for the first time from Vietnam. Taxonomic review for all species is provided with photos of the adults for the species.

In Vietnam, the moths were reported by some foreign entomologist such as de Joannis (1900), Ronkay (1989), Speidel & Kononenko (1998), Park et al. (2006), and Lien et al. (2008). In 1928 -1929 de Joannis created the original data of moths. His final reports on Lepidoptera were 45 families, 611 species of Noctuidae, and 461 species of Pyralidae. After the Vietnam War in North (1954), many times were collected in North Vietnam by National Institute of Plant Protection (NIPP). But all of them focused on fauna of the agricultural pests. According to the publication of NIPP (1967-1968), 533 species of 37 families of which there were 91 species of Noctuidae in the North Vietnam and some other moths known as the insect pests have been reported. In 1977 there were 77 species of Pyralidae known as the insect pests in the North Vietnam. The purpose of this study is to assess diversity of Lepidoptera order and to clarify the fauna in the Northern part of Vietnam, base on the Korea Vietnam collaborative insect-research project (2004-2006). The collecting have been conducted in four National Parks (Tam Dao, Cuc Phuong, Ba Be, and Bach Ma) Given results of the survey in the North of Vietnam from 2002 to 2006, 816 species of Lepidoptera classified by 4 families; Noctuidae (564 species), Pyraloidae (201 species), Sphingidae (28 species), and Lecithoceridae (23 species). Many of the identified species of macro-moths including Noctuidae, Pyraloidae and Lecithoceridae are known as the very newest one in Vietnam.

Two species of peltoperlid stonefly nymphs, Cryptoperla bisaeta (Kawai) and Cryptoperla sp. 1 (Plecoptera, Peltoperlidae), are described from Vietnam. Their descriptions, diagnoses, photographs, and taxonomic remarks are provided.

Twelve new species, Cryphia herczigi sp. nov., C. hohuana sp. nov., Odontestra lasxlogabe sp. nov., O. attila sp. nov., Xylena plumbeopaca sp. nov., Taivaleria rebrifasciata sp. nov., Hemiglaea radiata sp. nov., Nyctycia signa sp. nov., Fabiania pulla sp. nov., F. satellitia sp. nov., F. marki sp. nov., Asidemia albovitta sp. nov., and three new subspecies, Xestia fuscostigma csoevarii ssp. nov., Karana hoenei marcida ssp. nov. and genera, Taivaleria gen. nov. and Fabiania gen. nov., are established, and taxonomic notes for some little known noctuids are given. Illustrations of the male or the female genitalia for 45 species, and 34 images of adults are provided.
