Review of the sejunctus Species Group of the Split-footed Lacewing Genus Osmylops Banks (Neuroptera: Nymphidae), with Remarks on the Functional Morphology of Terminalic Coupling

The sejunctus species group is created for two Australian species of the split-footed lacewing genus Osmylops. the species group is characterised, Osmylops sejunctus (Walker) is redescribed and O. ectoarticulatus n.sp. is described. the male and female terminalia of both species are illustrated. Prior literature references to the species of the sejunctus group are clarified. Males and females of the sejunctus group possess coordinated, species-specific, suites of terminalic structures. the probable functions of these morphological structures during copulation are discussed.     

One new and one newly recorded species of the genus Amraica Moore, 1888 (Lepidoptera: Geometridae: Ennominae) from China,with diagnoses of the Chinese species

The genus Amraica Moore, 1888 in China is reviewed. In addition to the four species and three subspecies already known, one new species, A. prolata sp. nov. is described and one newly recorded species, A. ferrolavata ( Walker, 1863 (imprint 1862) ) is redescribed. The generic characters, based on all species, are summarized. Illustrations of external features and genitalia are presented.     

A revision of Neomegalotomus (Hemiptera: Alydidae)

We recognize two species in Neomegalotomus, N. parvus (Westwood), the type species; and N. rufipes (Westwood). The two species are redescribed from type specimens, and are keyed. We synonymize the following species with Neomegalotomus parvus: N. simplex (Westwood), N. latifascia (Berg), and N. pallescens (St?l) (all new synonymies). We synonymize N. jamaicensis (Westwood) with N. rufipes (new synonymy). The type specimens of all species hitherto placed in the genus are also redescribed, except those of N. debilis (Walker) and N. vicinus (Westwood). N. parvus occurs from México through Central America into northern Argentina and east into Venezuela and adjacent Caribbean islands. N. rufipes is widespread in the Caribbean south towards Venezuela. The two species overlap in distribution: N. parvus is found on St. Vincent and Tobago, whereas N. rufipes occurs on Grenada, which lies between those two islands.     

Revision of the Australian species of Hyalobathra Meyrick (Lepidoptera: Pyraloidea: Crambidae: Pyraustinae) based on adult morphology and with description of a new species

Abstract The genus Hyalobathra Meyrick is redefined based on five Australian species including the type  species. The four named Australian species, H. archeleuca Meyrick, H. unicolor (Warren) , H. miniosalis (Guenée) and H. minialis (Warren), are redescribed and a new species, H. crenulata sp. n., is described . Hyalobathra unicolor is removed from synonymy with H. illectalis (Walker), and lectotypes are designated for H. archeleuca , H. minialis and for H. rhodoplecta Turner, a synonym of H. miniosalis . The presence of H. paupellalis (Lederer) in Australia could not be confirmed, but its genitalia are figured. Two previously included species, ' Hyalobathra ' aequalis (Lederer) and ' H .'  brevialis (Walker), are excluded from Hyalobathra, as they lack its generic apomorphies, but cannot at present be assigned to any other genus.     

Faustulid trematodes (Digenea) from marine fishes of Australia

Twelve species of faustulid trematode are described or redescribed from Australian marine fishes. Bacciger lesteri Bray, 1982 and B. sprenti Bray, 1982 are redescribed from Selenotoca multifasciata from Moreton Bay. It is suggested that the original host record for these species, Mugil sp., was incorrect. The genera Discogastroides, Odontocotyle and Pseudodiscogasteroides are synonymised with Paradiscogaster. The new combinations Paradiscogaster arabi (Hafeezullah & Siddiqi, 1970), P. hainanensis (Shen, 1970), P. indicus (Srivastava, 1939), P. macrostomus (Shimazu & Kamegai, 1990), P. ostracii (Yamaguti, 1934) and P. pritchardae (Gupta & Ahmad, 1978) are proposed. Discogasteroides hawaiensis Hanson, 1955 is synonymised with P. ostracii. P. macrostomus and P. ostracii are redescribed from Ostracion meleagris and O. cubicus from the Great Barrier Reef. P. farooqii Hafeezullah & Siddiqi, 1970 is redescribed from Monodactylus argenteus from Moreton Bay. The following new species are described: P. machidai n. sp. from Pomacanthus semicirculatus and P. sexstriatus from the Great Barrier Reef, P. dweorg n. sp. from Meuschenia galii, P. lobomyzon n. sp. from Tilodon sexfasciatus and P. habilis n. sp. from Pelates octolineatus, all from Western Australia. Antorchis pomacanthi (Hafeezullah & Siddiqi, 1970) Machida, 1975 is redescribed from Pomacanthus semicirculatus and P. sexstriatus from the Great Barrier Reef. The new combination Antorchis intermedius (Madhavi, 1975) is proposed for Parantorchis intermedius. Parayamagutia ostracionis is redescribed from O. cubicus from the Great Barrier Reef. Trigonocryptus conus is redescribed from Arothron hispidus from South-east Queensland and from A. nigropunctatus from the Great Barrier Reef. The new combination Trigonocryptus australiensis (Kurochkin, 1970) is proposed for Pseudodiscogasteroides australiensis. The Echinobrevicecinae is reduced to synonymy with the Faustulidae.

Taxonomic Review of Creontiades Distant in Australia (Hemiptera: Miridae: Mirinae)

The two species of Creontiades Distant occurring in Australia, C. dilutus (Stål) (Australian endemic) and C. pacificus (Stål) (China, several countries in the Oriental and Australian regions including Tahiti and Micronesian islands) are redescribed, illustrated and their distributions are mapped. Megacoelum modestum (Distant) and C. virescens Reuter are synonymised with C. dilutus , and C. pallidifer (Walker) with C. pacificus. Available host plant information is provided for both species. C. dilutus , commonly known as green mirid, is a pest of cotton, potato, stone fruit, lucerne and other crops in certain parts of Australia. the generic limits of Creontiades and the closely related, world-wide distributed Megaceolum Fieber are reviewed based on examination of Australian species and the type species.

中国奥胸须夜蛾属Oxaenanus Swinhoe研究并记一新种（鳞翅目：裳蛾科：长须夜蛾亚科）

通过解剖Oxaenanus scopigeralis正模标本和同种雌雄外生殖器,发现O.scopigeralis(Moore,1867),sp.rev.&comb.nov.,(模式产地:印度)命名有效,其曾被认为是O.brontesalis(Walker,1858)(模式产地:婆罗洲)的同物异名.张,韩二人2019年发表的云南奥胸须夜蛾O.yunnana(模式产地:云南)应为O.scopigeralis的同物异名.作者在海南省采集到了奥胸须夜蛾属Oxaenanus 1新种海南奥胸须夜蛾Oxaenanus hainana sp.nov.,其与O.scopigeralis近似,但海南奥胸须夜蛾的前后翅亚外缘线更加模糊,抱器端骨化突起更短更细,阳茎端膜也更加复杂多变.     

The plam-feeding planthopper genus Ommatissus (Homoptera: Fulgoroidea: Tropiduchidae)

Abstract The tribe Trypetimorphini, the genus Ommatissus , and its two subgenera and eleven species are redescribed or described as new. Evidence for the monophyly of both the genus and of the tribe to which it belongs is examined; it is concluded that while the genus is monophyletic, the monophyly of the tribe is in doubt. Keys for the separation of the three genera of the tribe and for all of the known species of Ommatissus are presented. A new subgenus of Ommatissus is described: O.(Opatissus) , with the type-species O.vietnamicus . Four new species are described: Ommatissus magribus from Morocco, O.kamerunus from Cameroon, O.natalensis from South Africa and O.vietnamicus from Vietnam. The 'Dubas bug', Ommatissus lybicus Bergevin, formerly regarded as a variety of O.binotatus Fieber, is raised to full species status. Trichoduchus is synonymized with Trypetimorpha resulting in the new combinations Trypetimorpha biermani Dammerman, T.china Wu and T.japonicus Ishihara. Trichoduchus japonicus Fennah is synonymized with Trypetimorpha japonicus Ishihara.
