梨食芽蛾是桃白小卷蛾一个亲缘新种(英文)

梨食芽蛾在中国记载已有数十年历史、但迄今只有属名尚无种名。其原因在於它和桃白小卷蛾(白小食心虫)Spilonota albicana(Motschulsky)的外形、翅花纹等很相似。经分别饲育和详细比较、发现它们在生物学上有着明显的区别、在雌性外生殖器和幼虫色泽、毛片上都存在固定的不同。因此,将它定为新种,中名叫梨白小卷蛾,学名为Spilonota pyrusicola Liu et Liu,sp.nov.。     

A review of the genus Spilonota Stephens (Lepidoptera: Tortricidae) in North Korea

Four species of the genus Spilonota Stephens, belonging to the subfamily Olethreutinae (Lepidoptera, Tortricidae), are reviewed from North Korea, based on the materials of Hungarian Natural History Museum. Among them, two species, Spilonota lechriaspis Meyrick, 1932 and Spilonota ocellana (Denis et Schiffermüller, 1775), are reported for the first time from North Korea. Photos of adults and the genitalia are provided with brief comments on the distribution. Also a key for the species is given.     

A new capillariid (nematoda) parasitizing Heterandria bimaculata (Heckel, 1848) (Poeciliidae) in Mexico

A new nematode species, Freitascapillaria moraveci n. sp., is described; it was obtained from specimens recovered from the gall bladder of the 2-spot livebearer Heterandrá bimaculata (Heckel, 1848) from La Antigua River, State of Veracruz, Mexico. The new species is assigned to Freitascapillaria Moravec 1982; it is largely characterized by the posterior end of the males, which is laterally expanded without distinct projections. Freitascapillaria moraveci n. sp. differs from the only other species of the genus, F. maxillosa, by the absence of wing-like cells at the esophago-intestinal junction, which are present in the latter species; stichosoma consists of 30-36 stichocytes (F. moraveci) versus 40-60 stichocytes (F. maxillosa) in both males and females and the presence of a well-developed spicule.     

Two new species of Pharyngodonidae (Nematoda: Oxyuroidea) and other nematodes in Agama caudospina (Squamata: Agamidae) from Kenya, Africa

Parapharyngodon kenyaensis n. sp. and Thelandros samburuensis n. sp. (Nematoda: Pharyngodonidae) from the large intestine of the agamid lizard (Agama caudospina) are described and illustrated. Parapharyngodon kenyaensis n. sp. is the 41st species assigned to the genus, and it differs from other species in that genus by possessing 3 pairs of caudal papillae, cloacal lip adornment, and spicules of 112-120 microm in length. Thelandros samburuensis n. sp. is the 31st species assigned to the genus, and it differs from other species in that genus by possessing swollen posterior annulations, 6 caudal papillae, a smooth anterior cloacal lip, and spicules of 43-52 microm in length. In addition to the 2 new nematode species, Abbreviata ortleppi (Nematoda: Physalopteridae) and Strongyluris ornata (Nematoda: Heterakidae) were found.     

桃白小卷蛾和梨食芽蛾辨正

澄清了两种害虫：梨食芽蛾一年发生1代,以小幼虫在山植树翘皮下越冬,早春出蛰为害芽、花蕾、嫩梢及叶片,老熟后在花序或卷叶中化肾;桃白小卷蛾一年发生两代,以老熟幼虫在地面缀连叶片做茧越冬,春季在茧中化蛹,其幼虫只为害果实。两者幼虫和成虫可根据形态特征鉴别。     

Pseudorhabdosynochus argus n. sp. (Monogenea: Diplectanidae) from Cephalopholis argus, P. minutus n. sp. and Diplectanum nanus n. sp. from C. sonnerati and other monogeneans from Cephalopholis spp. (Perciformes: Serranidae) off Australia and New Caledonia

Monogeneans from three species of Cephalopholis, namely C. argus, C. sonnerati and C. boenak, are described from fish caught off New Caledonia, South Pacific, with comparisons with material from off Queensland, Australia. Pseudorhabdosynochus argus n. sp. from C. argus is present off New Caledonia and Australia; it is characterised by its male quadriloculate organ with very elongate cone, and its sclerotised vagina with anterior trumpet, coiled primary canal and distal part with two chambers and an accessory part. C. boenak has no monogeneans off New Caledonia, but off Australia it harbours Pseudorhabdosynochus sp., a new species which is morphologically related to P. argus. P. minutus n. sp. from C. sonnerati is characterised by its minute body and a sclerotised vagina with two spherical chambers. Diplectanum nanus n. sp. from C. sonnerati is characterised by its very small funnel-shaped male copulatory organ and minute body. A new species, Haliotrema sp. from C. sonnerati is characterised by a very elongate tubular penis; it is distinct from H. cromileptis Young, 1968 (redescribed herein from specimens collected from Cromileptes altivelis off New Caledonia). The species described here include the first members of Pseudorhabdosynochus and the first diplectanids described from species of Cephalopholis. There is no evidence for a clade of Pseudorhabdosynochus species specific to members of Cephalopholis, since the species described here share similarities with other species from Epinephelus. However, it is suggested that the gill structure of Cephalopholis spp. imposes selection toward small body sizes for monogeneans.     

New Dalyelliidae (Platyhelminthes, Rhabditophora) from Buenos Aires Province, Argentina, and their stylet ultrastructure

Two new species of Dalyellidae, Dalyellia callvucurai n. sp. and Gieysztoria namuncurai n. sp., are described from temporary freshwater environments in central Buenos Aires Province, Argentina. The ultrastructure of the stylets of both species is also described. The new species of the genus Dalyellia is the second species of the genus found in the neotropics and the first whose stylet has been studied with scanning electron microscopy. Gieysztoria namuncurai n. sp. joins the seven species of the genus known in Argentina. The ultrastructural characteristics of the stylet place it in the Inaequales group, with complex stylets.     

A new species of Spinicauda (Nematoda: Heterakidae) and other endoparasites in Platymantis pelewensis (Anura: Ranidae) from the Palau Islands, Republic of Belau, Oceanica

Spinicauda fisheri n. sp. from the intestine of Platymantis pelewensis collected in the Palau Islands, Republic of Belau, is described and illustrated. Spinicauda fisheri represents the 12th species assigned to the genus and the first from Oceanica. It is most similar to Spinicauda spinicauda in that the tail ends in a filament, but it has 19 pairs of caudal papillae as compared with 5 pairs in S. spinicauda. In addition to S. fisheri, 2 species of Cestoda, cysticercoids of Joyeuxiella sp. and tetrathyridia of Mesocestoides sp., 2 species of Nematoda, Oswaldocruzia bakeri and Physocephalus sp. (larvae in cysts), 1 species of Acanthocephala, Acanthocephalus bufonis, and 1 species of Pentastomida, nymphs of Kiricephalus pattoni were identified.

Novelties in Fissistigma (Annonaceae) from Borneo

Five new species of Fissistigma are described from Borneo. Fissistigma brevistipitatum sp. nov. is a species of lowland and hill forest mostly recorded from Sabah. Fissistigma bygravei sp. nov. is similar to F. hypoglaucum (Miq.) Merr. of the Malay Peninsula and Sumatra. Fissistigma carrii sp. nov. is from Mount Kinabalu. Fissistigma crassicaule is a robust plant known from a couple of collections from Sarawak. Fissistigma montanum sp. nov. is a species from hill and montane forest recorded from Brunei, Sabah and Sarawak. A new combination in Fissistigma is made for Melodorum multivenium Diels. Two recently described species of Fissistigma from Borneo ( F. cordifolium Irawan and F. magnisepalum Irawan) are reduced to synonymy of Friesodielsia excisa (Miq.) Steenis and Friesodielsia affinis (Hook. f. & Thomson) D. Das, respectively. Both species of Friesodielsia are lectotypified.     

A new species of myxozoan (Myxosporea) from the brain and spinal cord of rainbow trout (Oncorhynchus mykiss) from Idaho

A new species of Myxosporea, Myxobolus neurotropus n. sp., is described from the brain and spinal cord of rainbow trout (Oncorhynchus mykiss) from Duncan Creek, Owyhee County, Idaho. Spores are oval, have 2 pyriform polar capsules, and possess a thick spore wall (sutural rim) with a short intracapsular offshoot. The mean spore dimensions are length 11.8 microm, width 10.8 microm, and thickness 8.8 microm. This myxozoan is compared to other described Myxobolus species found in cranial tissues of salmonids in terms of spore morphology and phylogenetic analysis. Because it is found in brain and spinal cord, it is encountered while performing screening tests for Myxobolus cerebralis, the causative agent of salmonid whirling disease. Where chronic inflammation and granulomatous lesions are associated with M. cerebralis, histological examination shows no host response to M. neurotropus n. sp. A diagnostic polymerase chain reaction (PCR) test is included as an aid in properly identifying the species.     

Three new genera of Braconini from the Afrotropical and Australian regions (Insecta, Hymenoptera, Braconidae)

Jugubracon gen. n (type species: Jugubracon ferrugineus sp.n.) from New Guinea is described and illustrated. Jugubracon is related to Bracon , from which it is distinguished by a mid-longitudinally carinate 1st metasomal tergite and a curved fore-wing vein 1-SR+M. Kimavu gen.n. (type species: Kimavu fulvus sp.n.) from Sierra Leone, South Africa and Madagascar is described and illustrated. Kimavu is related to Cratocnema Szépligeti, from which it is distinguished by having long antennae which, in females, have a pale coloured annulus. Brucon annulicornis Brues, 1924, is transferred to Kimavu. Mollibracon gen.n. (type species: Bracon bimaris Turner, 1918) from Australia is described and illustrated. Mollibracon is related to Myosoma Brullé, from which it is distinguished by a strongly curved fore-wing vein 1-SR+M.     

New World Thripidae (Thysanoptera) with nine-segmented antennae

A key is provided to the New World genera of Thripidae with nine-segmented antennae. Psydrothrips kewi gen. et sp. nov. is described, a discussion is given of the morphology of the Neotropical genera which it resembles, and keys to species are provided.     

Monograph of the solenofilomorphidae (Turbellaria: Acoela)

Morphological studies of eleven new species in the family permitted reconstruction of progressive evolutionary lines, and this strongly implies progressive evolutionary lines for other acoela. Solenofilomorpha funilis n. sp., Myopea crassula n. g. n. sp., M. latafaucium n. sp., Fusantrum rhammiphorum n. g. n. sp. and Endocincta punctata n. g. n. sp. are described from the coast of South Carolina, U.S.A., and S. guaymensis n. sp. is described from the Gulf of California. Five additional unnamed species from the U. S. Pacific Coast, Sweden and Tunisia are briefly described. Two species groupings were based on correlation between two different arrangements of pharynx muscles and trio arrangements of antrum muscles and further correlations with lesser characters. The membership of the two groupings in a single family make it clear that evolution proceeded by addition of structures to a less complex common ancestor. Functional and behavioral considerations support the evolutionary path drawn from morphology. Distinctive statocyst structure, ciliary interconnections and sperm morphology shared by acoels show them to have a common ancestry, but clearly different pharynges and male structures cannot be consistent with evolution by reductions. A common ancestor of low complexity has probably given rise to several partly parallel evolutionary lines which together form the structurally diverse Acoela. The history of acoel systematics is also briefly summarized.     

A new species of Rhabdias (Nematoda: Rhabdiasidae) in Calotes versicolor (Squamata: Agamidae) from Singapore

Rhabdias singaporensis n. sp. (Rhabditida: Rhabdiasidae) from the lungs of Calotes versicolor (Squamata: Agamidae) from Singapore is described and illustrated. Rhabdias singaporensis n. sp. represents the 77th species assigned to the genus, the eighth of the Asian region, and the second from Singapore. The distinguishing characteristic of the new species is the location of the excretory pore. In all species of Rhabdias for which excretory pore location data are available, the excretory pore is situated just posterior to the level of the nerve ring; in R. singaporensis , it lies near the esophageointestinal junction.     

Systematics of the bryozoan genus Macropora (Cheilostomata)

Macropora is a distinctive genus of anascan cheilostomes. All species have large zooids with an extensive cryptocystal frontal shield perforated by numerous pores through which parietal muscle strands pass. Also characteristic of Macropora are the calcified opercula closing the d -shaped orifice, avicularia resembling autozooids but having slightly enlarged, typically crenulated opercula/mandibles, and large ovicells that are often costate. This mostly Australasian genus has a documented fossil record stretching back to the Eocene. Here we revise the generic diagnosis of Macropora and describe eight new species from New Zealand (three Recent: M. nodulosa sp. nov. , M. filifera sp. nov. and M. carlosi sp. nov. ; five fossil: M. septispinosa sp. nov. , M. similis sp. nov. , M. pittensis sp. nov. , M. leeae sp. nov. and M. bullata sp. nov. ) and one new species from Japan ( M. mawatariorum sp. nov. ), the only species known with certainty to occur in the northern hemisphere. New observations are given for some previously described species, several of which are illustrated using SEM for the first time. The northern hemisphere Upper Cretaceous species Monoporella exsculpta (Marsson), showing features allowing it to be placed tentatively in the stem-group of Macropora , is redescribed. Attempts to resolve the phylogenetic relationships of species within Macropora were hampered by the relatively few morphological characters compared with the number of species, and it proved impossible to obtain a phylogeny robust to slight changes in taxon and/or character inclusion. The favoured cladogram has poor bootstrap and Bremer support, and its stratigraphical and biogeographical congruences are low.  © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society , 2008, 153 , 115–146.     

New genus, new species of Cestoda (Anoplocephalidae), new species of Nematoda (Cosmocercidae) and other helminths in Cyrtodactylus louisiadensis (Sauria: Gekkonidae) from Papua New Guinea

Gekkotaenia novaeguineaensis n. gen., n. sp. (Cestoda: Anoplocephalidae) from the small intestine and Cosmocerca zugi n. sp. (Nematoda: Cosmocercidae) from the large intestine of the ring-tailed gecko, Cyrtodactylus louisiadensis (Sauria: Gekkonidae) are described and illustrated. Gekkotaenia novaeguineaensis n. gen., n. sp. is unique among the acraspedote Linstowiinae in possessing a poral female reproductory system. Cosmocerca zugi n. sp. is the 22nd species to be assigned to the genus and differs from other species in the genus by possessing 4 pairs of rosette papillae on plectanes and having a gubernaculum longer than the spicules. It is the fifth species to be described from the Australian biogeographical region. Eight additional helminth species were found: the digenean, Allopharynx macallisteri; 2 cestodes, cysticercoids of Cyclophyllidea gen. sp. and tetrathyridia of Mesocestoides sp.; 5 nematodes, larvae in cysts of Abbreviata sp., Aplectana macintoshii, Oswaldocruzia bakeri, Parapharyngodon maplestonei, and an undescribed species of Physalopteroides. Cyrtodactylus louisiadensis represents a new host record for each of these helminths.     

Three new species of genus Myrmica (Hymenoptera: Formicidae) from Himalaya

Three new species of the genus Myrmica are described from the Himalayas. Myrmica curvispinosa sp. nov., Myrmica kothiensis sp. nov. and Myrmica religiosa sp. nov. belong to the Myrmica inezae species group, which is earlier represented by 4 species. Myrmica curvispinosa sp. nov. is described based on worker and gyne, with a report of ergatoid as well. Myrmica kothiensis sp. nov. and Myrmica religiosa sp. nov. are described based on worker caste only. A key to the species of the Myrmica inezae species group has been provided in the following.     

New species of oribatid mites (Acari: Oribatida) of the genera Belbodamaeus (Damaeidae), Malaconothrus (Malaconothridae) and Nothrus (Nothridae) from India

Three new oribatid mite species, Belbodamaeus indicus sp. n. (Damaeidae), Malaconothrus macrofoveolatus sp. n. (Malaconothridae) and Nothrus phylliformis sp. n. (Nothridae), are described from Indian soils. Belbodamaeus indicus sp. n. is clearly distinguishable from all species of Belbodamaeus by the absence of discidia, very long sensilli and morphology of parastigmatic tubercles Sa. Malaconothrus macrofoveolatus sp. n. is very similar morphologically to Malaconothrus yinae Yamamoto, Aoki, Wang & Hu, 1993 from China, however it differs from the latter by the morphology of notogastral and genital setae, size of body foveolae, epimeral formula, and number of genital setae. Nothrus phylliformis sp. n. is very similar morphologically to Nothrus mystax Mahunka, 1986 from Tanzania, however it differs from the latter by the smaller body size, length of interlamellar setae and the position of notogastral setae d ₁. An identification key to known species of Belbodamaeus is presented.
