Juvenile stages of Punctoribates punctum (C. L. Koch, 1839) and P. hexagonus Berlese, 1908 are redescribed, those of P. sellnicki Willmann, 1928 are described for the first time, and both juveniles and adults of all species are illustrated. The juvenile stages of these species are similar in body shape and the number of setae on the prodorsum, gastronotum and anal, anogenital and epimeral regions, but differ in the shape and length of some prodorsal and gastronotal setae. Keys to the larvae and nymphs of these species are prepared.

Eleven new species of the family Mysmenidae occurring in China, in addition to one known species, Mysmenella gongi Yin, Peng et Bao, 2004, that was reported from Hunan Province, are diagnosed, described and illustrated. Three genera, i.e., Calodipoena, Mysmena, and Trogloneta, are firstly reported in China. Mysmenella pseudojobi sp. nov., where is found hitherto at the northest range of distribution of the family in China, and Trogloneta denticocleari sp. nov. is collected in caves. Mysmena spirala sp. nov. is collected from rainforest in Hainan Province. Calodipoena biangulata sp. nov., C. cornigera sp. nov., Mysmena zhengi sp. nov., M. rostella sp. nov., M. furca sp. nov., M. arcilongus sp. nov., Mysmenella menglunensis sp. nov. and Trogloneta speciosum sp. nov., from Xishuangbanna in Yunnan Province, are collected by fogging. Natural history and distributional map are provided.

Two new mayfly species, Cheirolgisca ningchengensis gen. and sp. nov. and Olgisca angusticubitis sp. nov. from the Middle Jurassic Jiulongshan Formation of Ningcheng County, Inner Mongolia, NE China are described herein, both attributed to the extant family, Siphlonuridae. The Mesozoic mayfly imagoes have been rarely reported, thus the new material with well-preserved gonostyles provides valuable evolutionary evidence on this family.

The new extinct species Thionia douglundbergi sp. nov. of the recent genus Thionia Stål, 1859 from the Miocene Dominican amber is described. The morphological features of the genus are discussed in brief. The fossil record of ‘higher’ Fulgoroidea in New World fossil resins is discussed.

The dictyopharids planthopper genus Dictyophara Germar, 1833 from China is revised and restricted in Palaearctic Region of northern China. Only four recognized Dictyophara species are: D. europaea (Linnaeus, 1767), D. koreana Matsumura, 1915, D. nekkana Matsumura, 1940 and D. pannonica (Germar, 1830), which the former two are recorded from China for the first time. One new generic and three new specific synonyms are recognized: Dictyophara Germar, 1833 = Togaphora Matsumura, 1940 syn. nov.; D. koreana Matsumura, 1915 = Centomera manchurica Kato, 1933 syn. nov. = Togaphora hokuryonis Matsumura, 1940 syn. nov.; D. nekkana Matsumura, 1940 = Dictyophara kaszabi Dlabola, 1967 syn. nov. Photographs of the adults of all known species are presented. Descriptions of the genus and its included species are provided together with structural illustrations of the male genitalia. A key and a distribution map to the four species of Dictyophara from China are provided.

Apterous and alate viviparous female, oviparous female and alate male of Macrosiphum symphyti sp. nov. living on Symphytum asperum (Boraginaceae) are described and illustrated. A key to the apterous viviparous females of the genus Macrosiphum Passerini species distributed in Georgia is given.

A new Hypenella nanlingensis is described from Guangdong Province, southern China. It is likely to represent a Palaearctic relict in the Oriental Realm. A key to the four species known in the world is given.

Five Tachydromia species are reported from Yunnan province: two species were previously known from Thailand: T. thaica Shamshev et Grootaert, 2005 and T. terricoloides Shamshev et Grootaert, 2005. Three species are described as new for science: T. mengyangensis sp. nov., T. menglunensis sp. nov. and T. yunnanensis sp. nov. A key to the ten known species of China is given.

Only two species of the family Callirhipidae have been described from the Afrotropical zoogeographical region. Callirhipis philiberti Fairmaire, 1891 from the Seychelles is redescribed based on the type specimen and recently collected material. A study of the type specimen of the enigmatic Madagascan species C. hovana Fairmaire, 1901 revealed, that it is in fact a member of the family Elateridae, and is conspecific with Hemiopinus hildebrandti Fairmaire, 1883. Therefore C. hovana syn. nov. is here regarded as a junior subjective synonym of H. hildebrandti. The presently known distribution of the family Callirhipidae in the Afrotropical zoogeographical region is briefly discussed.

The genus Setylaides Stebnicka, 1994, is revised, including one new species, S. chiangmai sp. nov. described from Thailand. Lectotypes of Dialytes foveatus Schmidt, D. punctatus Schmidt and D. javanus Schmidt are designated and a key to species is provided. At present, five species are recognized within the genus, occurring exclusively in the Oriental region.

The genus Synona Pope (1989) (Coleoptera: Coccinellidae: Coccinellini) is revised, with particular reference to the Oriental and Australasian species complex widely identified as S. melanaria (Mulsant, 1850), the type species. It is concluded that the name S. melanaria ought to be applied to the species currently known as S. seminigra (Weise, 1902) and a lectotype is designated for S. melanaria. Synona seminigra (Weise, 1902) is synonymised with S. melanaria (new synonym). Coccinella cassidoides Montrouzier, 1857 (not C. cassidoides Donovan, 1798), and Harmonia anthracina Iablokoff-Khnzorian, 1982 are reduced to junior synonyms of S. melanaria (Mulsant, 1850) (new synonyms). Synona melanopepla (Mulsant, 1850), distributed in the Indian subcontinent and hitherto considered as a synonym of S. melanaria, is recognized as a valid species (status revived). Synona rougeti (Mulsant, 1866), Lemnia melanoptera lablokoff-Khnzorian, 1978, and Lemnia (Synia) martini lablokoff-Khnzorian, 1984 are synonymised with S. melanopepla (new synonyms). Three new species are described: S. obscura sp. nov. (India), S. consanguinea sp. nov. (China, Taiwan, Thailand, Vietnam), S. philippinensis sp. nov. (Philippines). A key to the species is provided, along with biological information wherever available. Coelophora vidua Mulsant, 1850 is synonymised with Coelophora inaequalis (Fabricius, 1775) (new synonym).

Three new species of Apophylia are described, illustrated and compared with related taxa: A. liska sp. nov. (India: Meghalaya), A. blecha sp. nov. and A. algie sp. nov. (both India: Tamil Nadu). Apophylia pavlae Bezděk, 2003 is proposed as a new synonym of A. melli Gressitt et Kimoto, 1963. New faunistical data of 34 Apophylia species are presented. Apophylia phuphanensis Bezděk, 2006 is newly reported from Vietnam, A. vietnamica Samoderzhenkov, 1988 from China, A. denisae Bezděk, 2005 from Thailand, A. hajeki Bezděk, 2003 from India, A. schawalleri Medvedev, 1992 from China and A. samoderzhenkovi Medvedev, 1993 from India.

Aulexis erythrodera, a new species of leaf-beetle from Myanmar is described and illustrated.

Three species of Cassida Linné, 1758 from NE India are described as new to the science: Cassida mishmiensis sp. nov. (Arunachal Pradesh), C. atrosignata sp. nov. (Arunachal Pradesh) and C. pacholatkoi sp. nov. (Meghalaya). Type material of Thlaspida obenbergeri Spaeth, 1928 has been studied and a lectotype designation is given here. Thlaspida obenbergeri is transferred to the genus Cassida (comb, nov.) and a following new synonym is proposed: Cassida crucipennis Borowiec, 2003 = Cassida obenbergeri (Spaeth, 1928).

Egg, first and last instar larvae and pupa of Cyrtonota lateralis (Linnaeus, 1758), a member of the tribe Mesomphalini Chapuis, 1875 (= Stolaini Hincks, 1952), have been described and figured in detail for the first time. Immatures were figured using light microscope, for the first instar larva also SEM photos were prepared.

The first instar larva of Physonota alutacea Boheman, 1854, a member of the tribe Physonotini Spaeth, 1942, and the mature larva and pupa of Asteriza flavicornis (Olivier, 1790), a member of the tribe Asterizini Hincks, 1952, are described for the first time. The mature larva and the pupa of Physonota alutacea are redescribed. Immatures are figured and described using light microscopy, the first instar larva of Physonota alutacea using scanning electron microscopy. Similarities in the larval morphologies of Cistudinella Champion, 1894, a member of the tribe Ischyrosonychini, Chapuis, 1875, and Physonota suggest both genera are close phylogenetically and should be placed in a single tribe. The additional similarities between the mature larva of Asteriza and those of Physonota and Cistudinella suggest all three genera should be placed within a single tribe.
