大豆蚜触角嗅觉感器结构及其功能

采用扫描电镜观察大豆蚜Aphis giycines各型触角上嗅觉感器的细微结构,结合触角电位记录,发现大豆蚜有翅孤雌生殖蚜对萜烯衍生物的感受部位在第6节原生感器上,而萜烯烃类则在第5节原生感器上,两原生感器都对绿叶气味和芳香类起嗅觉反应。末端2节上还有其它化学感器对植物气味起反应。因此,各型对植物气味的感觉部位在末端2节上。各型对报警信息素的作用部位主要在第6节原生感器上,无翅型第5节原生感器和有翅型第3节次生感器也有一定的感觉能力。     

First report of the genus Kisaura Ross (Trichoptera, Philopotamidae) from India with the description of six new species

The genus Kisaura Ross, 1956 (Trichoptera, Philopotamidae, Philopotaminae) is reported from India the first time. Six new species are described and illustrated: Kisaura elongatasp. n., Kisaura eloctsp. n., Kisaura clavatasp. n., Kisaura gangtokensissp. n., Kisaura truncatasp. n., all from Gangtok (Sikkim) and Kisaura himachalicasp. n. from Barot (Himachal Pradesh). Male genitalia of this genus are distinguishable from those of other genera of the family by the pair of long lateral processes of tergum X, the well-developed mesoventral plates between two segments of the inferior appendages, and by the brush-like row of dark setae on the inner surfaces of the terminal segments (harpago) of the inferior appendages.     

各型桃蚜触角感器的比较研究

该文对桃蚜Myzus persicae(Sulzer)各型触角感器进行了比较研究。扫描电镜观察结果表明桃蚜具有钟形感器、毛形感器、原生感觉圈和次生感觉圈4种类型的触角感器。桃蚜各型触角感器的最大差异主要表现在次生感觉圈上,雄蚜、雌性母和有翅孤雌蚜具有次生感觉圈,雌性蚜、干母和无翅孤雌蚜无;但雄蚜具有的次生感觉圈数目多于雌性母和有翅孤雌蚜,且不仅仅分布在触角第3节,第4、5节也有分布。本文探讨了桃蚜触角感器在化学生态学上的功能作用,各型触角感器的差异与桃蚜寄主选择、迁移及交配行为的关系,并进一步分析了桃蚜触角感器的性二型现象。

Intraspecific differences in olfactory sensilla in relation to diet breadth in Uroleucon ambrosiae (Homoptera: Aphididae)

The olfactory plate organs found on the proximal segments of aphid antennae, the secondary rhinaria, were studied in apterae of the aphid Uroleucon ambrosiae. The numbers and shapes of these structures are important taxonomic characters in Aphididae, but they also show intraspecific variation within a morph. In this study, numbers were found to vary with aphid size but, independent of size, were greater in aphids collected in the eastern than in the southwestern United States. In addition, the sizes of rhinaria were greater in eastern than in southwestern aphids. These differences correlate with previously recorded differences in diet breadth and the efficiency of finding and settling on food: eastern aphids specialize on the host Ambrosia trifida, on which they settle relatively efficiently, while southwestern aphids are more generalized and less efficient. Greenhouse experiments demonstrated that differences in rhinaria are partly determined genetically. Southwestern aphids showed bilateral asymmetry in length of antennal segments though not in numbers of rhinaria, but only on certain adopted hosts that were apparently inferior for growth. The significance of these intraspecific differences is discussed in relation to the physiology, ecology, and evolution of host range.     

The family Ctenobelbidae (Acari,Oribatida), with description of a new species and discussion on systematic placement and taxonomic status of the genus Berndamerus Mahunka, 1977

The oribatid mite genus Berndamerus Mahunka, 1977 is transferred into the family Ctenobelbidae as the subgenus Ctenobelba (Berndamerus) Mahunka, 1977, stat. n. from the family Amerobelbidae. The known species of Berndamerus combined: C. (B.) bicostata (Berlese, 1910), comb. n., C. (B.) eremuloides (Berlese, 1910), comb. n., C. (B.) hellenica (Mahunka, 1977), comb. n. A new species, Ctenobelba (Berndamerus) bugiamapensis sp. n., is described from soil, Bu Gia Map National Park, southern Vietnam. It differs from the other species of the subgenus by the heterotrichy of notogastral setae, presence of adanal neotrichy and localization of adanal lyrifissures. Ctenobelbidae is recorded in Vietnam for the first time. A new diagnosis of the family Ctenobelbidae and the identification keys to the known subgenera of the genus Ctenobelba and species of the subgenus Ctenobelba (Berndamerus) are provided.     

Review of the millipede family Trichopolydesmidae in the Oriental realm (Diplopoda,Polydesmida), with descriptions of new genera and species

In the Oriental Region, the large, basically Northern Hemisphere family Trichopolydesmidae is shown to currently comprise 18 genera and 43 species. Based mainly on gonopod structure, all of them, as well as the whole family, are (re)diagnosed, including five new genera and seven new species. These new taxa are keyed, also being the first to be described from Indochina in general and from Vietnam in particular: Aporodesmella gen. n., with three species: A. securiformis sp. n. (the type species), A. similis sp. n. and A. tergalis sp. n., as well as the following four monotypic genera: Deharvengius gen. n., with D. bedosae sp. n., Gonatodesmus gen. n., with G. communicans sp. n., Helicodesmus gen. n., with H. anichkini sp. n., and Monstrodesmus gen. n., with M. flagellifer sp. n. In addition, Cocacolaria hauseri Hoffman, 1987, hitherto known only from New Ireland Island, Papua New Guinea, is redescribed based on material from Vanuatu whence it is recorded for the first time. One of the new genera, Gonatodesmus gen. n., provides a kind of transition or evolutionary bridge between Trichopolydesmidae and Opisotretidae, thus reinforcing the assignment of these two families to the single superfamily Trichopolydesmoidea.     

New records of the genus Iporhogas Granger (Hymenoptera,Braconidae, Rogadinae) from Vietnam,with description of four new species

Iporhogas albilateralis sp. n., I. contrastus sp. n., I. simulatus sp. n. and I. tricoloratus sp. n., from Vietnam are described and illustrated, and additionally, one species, Iporhogas guangxiensis Chen & He, 1997, is newly recorded for Vietnam’s fauna of the family Braconidae. A key to the five Vietnamese species of the genus Iporhogas and a checklist with distributions of the ten species are provided.     

<Emphasis Type="Italic">Foxtosognus rarus</Emphasis> gen. n., sp. n.—A new genus and species of copepods (Copepoda: Calanoida) from the abyssopelagic zone of the Kuril-Kamchatka Trench

A female of Foxtosognus rarus gen. n., sp. n., a new genus and species of copepods, is described from the abyss of the Kuril-Kamchatka Trench. The new genus is placed in the family Arctokonstantinidae, whose diagnosis is emended and supplemented with the following characters: mandibular basis with one to two setae; mandibular endopod one without setae; maxillular distal basal endite plus endopod with two to four setae or without setae. The features that distinguish Foxtosognusgen. n. from other representatives of this family are as follows: mandibular palp with a long endopod segment one, endopod segment two with seven setae, and exopod segment five with two setae; maxillula with distal basal endite lacking setae and separated from endopod bearing three setae; maxillular precoxal arthrite with seven to eight setae and exopod with four setae; maxilliped syncoxa without setae on precoxal endites and endopod of three segments. The genera Sognocalanus and Foxtonia earlier included in the Spinocalanidae are herein transferred to the Arctokonstantinidae.     

New cave-dwelling armored spiders (Araneae,Tetrablemmidae) from Southwest China

A new genus and five new species belonging to the family Tetrablemmidae are described from caves in Southwest China, i.e., Sinammaoxycera gen. & sp. n., Singaporemma banxiaoensis sp. n., Singaporemma wulongensis sp. n., Tetrablemma ziyaoensis sp. n. andTetrablemma menglaensis sp. n. The following new combination is proposed: Sinamma sanya (Lin & Li, 2010), comb. n. ex. Shearella Lehtinen, 1981. The relationships of the Sinamma gen. n. with other genera are discussed. Diagnoses and illustrations for all new taxa are given.     

A New Genus of Marine Scuticociliate (Protozoa, Ciliophora) from Northern China, with a Brief Note on Its Phylogenetic Position Inferred from Small Subunit Ribosomal DNA Sequence Data

ABSTRACT. The morphology, infraciliature, and silverline system of a new marine scuticociliate, Wilbertia typica n. g., n. sp., collected from coastal waters off northern China, were investigated. The new genus Wilbertia is characterized as follows: sculptured and dorso-ventrally flattened body; dominant buccal field that is almost completely surrounded by the paroral membrane; three apically positioned long membranelles, arranged in parallel; membranelle (M)1 and M2 prominent, M3 small; reticulate silverline system. The type species W. typica n. sp. is defined by having a conspicuous anterior beak-like protrusion; five to eight caudal cilia; M1 four-rowed, M2 two-rowed; M3, single-rowed, bipartite; 15 or 16 somatic kineties; contractile vacuole positioned just posterior to the buccal field; globular macronucleus. The small subunit ribosomal DNA sequence of W. typica is 98.5% similar to the similar morphotype, Eurystomatella sinica . Phylogenetic analyses indicate that Wilbertia groups with Eurystomatella sinica forming a branch that diverges at a deep level from all other pleuronematid scuticociliates. The molecular and morphological data indicate that Wilbertia should be placed within the family Eurystomatidae, which is closely related to the well-known Cyclidiidae.

Australian Assassins, Part I: A review of the Assassin Spiders (Araneae, Archaeidae) of mid-eastern Australia

The Assassin Spiders of the family Archaeidae are an ancient and iconic lineage of basal araneomorph spiders, characterised by a specialised araneophagic ecology and unique, 'pelican-like' cephalic morphology. Found throughout the rainforests, wet sclerophyll forests and mesic heathlands of south-western, south-eastern and north-eastern Australia, the genus Austrarchaea Forster & Platnick, 1984 includes a diverse assemblage of relictual, largely short-range endemic species. With recent dedicated field surveys and significant advances in our understanding of archaeid biology and ecology, numerous new species of assassin spiders have been discovered in the montane sub-tropical and warm-temperate closed forests of mid-eastern Australia, including several rare or enigmatic taxa and species of conservation concern. This fauna is revised and 17 new species are described from south-eastern Queensland and eastern New South Wales: Austrarchaea alanisp. n., Austrarchaea aleenaesp. n., Austrarchaea binfordaesp. n., Austrarchaea christopherisp. n., Austrarchaea clyneaesp. n., Austrarchaea cunninghamisp. n., Austrarchaea dianneaesp. n., Austrarchaea harmsisp. n., Austrarchaea helenaesp. n., Austrarchaea judyaesp. n., Austrarchaea mascordisp. n., Austrarchaea mcguiganaesp. n., Austrarchaea milledgeisp. n., Austrarchaea monteithisp. n., Austrarchaea platnickorumsp. n., Austrarchaea ravenisp. n. and Austrarchaea smithaesp. n. Adult specimens of the type species, Austrarchaea nodosa (Forster, 1956) are redescribed from the Lamington Plateau, south-eastern Queensland, and distinguished from the sympatric species Austrarchaea dianneaesp. n. A key to species and a molecular phylogenetic analysis of COI and COII mtDNA sequences complement the species-level taxonomy, with maps, habitat photos, natural history information and conservation assessments provided for all species.     

A revision of the spider genus Selenops Latreille, 1819 (Arachnida, Araneae, Selenopidae) in North America, Central America and the Caribbean

The spider genus Selenops Latreille, 1819 occurs in both the Old World and New World tropics and subtropics and contains nearly half of the species in the family Selenopidae Simon, 1897. In this paper the members of the genus Selenops found in North America, Central America, and on islands of the Caribbean are revised, excluding Cuban endemics. No taxonomic changes are currently made to the species from the southwestern United States. In total, 21 new species are described, including Selenops arikoksp. n., Selenops chamelasp. n., Selenops amonasp. n., Selenops bawekasp. n., Selenops bocacanadensissp. n., Selenops enriquillosp. n, Selenops ixchelsp. n., Selenops huetocatlsp. n., Selenops kalinagosp. n., Selenops oviedosp. n., Selenops morrosp. n., Selenops deniasp. n., Selenops duansp. n., Selenops malinalxochitlsp. n., Selenops oricuajosp. n., Selenops petenajtoysp. n., Selenops guerrerosp. n., Selenops makimakisp. n., Selenops souligasp. n., Selenops wilmotorumsp. n., and Selenops wilsonisp. n. Six species names were synonymized: Selenops lunatus Muma, 1953 syn. n. =Selenops candidus Muma, 1953; Selenops tehuacanus Muma 1953 syn. n., Selenops galapagoensis Banks, 1902 syn. n. and Selenops vagabundus Kraus, 1955 syn. n. = Selenops mexicanus Keyserling, 1880; Selenops santibanezi Valdez-Mondragón, 2010 syn. n. = Selenops nigromaculatus Keyserling, 1880; and Selenops salvadoranus Chamberlin, 1925 syn. n. = Selenops bifurcatus Banks, 1909. Lectotypes are designated for the following three species: Selenops marginalis F. O. Pickard-Cambridge, 1900 (♂), Selenops morosus Banks, 1898 (♂), and Selenops mexicanus Keyserling, 1880 (♀). The female neotype is designated for Selenops aissus Walckenaer, 1837. The males of Selenops bani Alayón-García, 1992 and Selenops marcanoi Alayón-García, 1992 are described for the first time, and the females of Selenops phaselus Muma, 1953 and Selenops geraldinae Corronca, 1996 are described for the first time. Almost all species are redescribed, barring Cuban endemics and a few species recently described. New illustrations are provided, including those of the internal female copulatory organs, many of which are illustrated for the first time. A key to species is also provided as are new distributional records.     

Taxonomy of the genus Peyerimhoffia Kieffer from Mainland China,with a description of seven new species (Diptera,Sciaridae)

The taxonomy of the genus Peyerimhoffia Kieffer in China was studied. Eight species were recognized, including seven new species that are herein described and illustrated: P. hamata sp. n., P. obesa sp. n., P. sparsula sp. n., P. longiprojecta sp. n., P. brachypodua sp. n., P. yunnana sp. n., and P. shennongjiana sp. n. In addition, P. vagabunda (Winnertz, 1867) is reported for the first time from China. A key to these Chinese species is provided.     

A reclassification of the millipede superfamily Trichopolydesmoidea,with descriptions of two new species from the Aegean region (Diplopoda,Polydesmida)

Two new species are described from caves in several Greek islands in the Aegean Sea: Galliocookia gracilis sp. n., a presumed troglobite from Rhodes, Dodecanese Islands, and Sphaeroparia simplex sp. n., likely a troglophile from Kithnos, Cyclades, and Chios, Eastern Sporades. These genera are assigned to the family Trichopolydesmidae Verhoeff, 1910. Because Sphaeroparia Attems, 1909, an Afrotropical genus, nicely bridges the gap, both morphologically and geographically, between the Euro-Mediterranean Trichopolydesmidae and the much more diverse, pantropical Fuhrmannodesmidae Brölemann, 1916, the latter family is considered as a new junior subjective synonym of the former, syn. n. Thus expanded, the family Trichopolydesmidae is rediagnosed and its position within the superfamily Trichopolydesmoidea refined. Because the families Mastigonodesmidae Attems, 1914, Macrosternodesmidae Brölemann, 1916 and Nearctodesmidae Chamberlin & Hoffman, 1950 are also formally synonymized with Trichopolydesmidae, syn. n., the Trichopolydesmoidea currently contains only two families, Trichopolydesmidae and Opisotretidae Hoffman, 1980.     

A new genus and species of deep-sea glass sponge (Porifera, Hexactinellida, Aulocalycidae) from the Indian Ocean

New hexactinellid sponges were collected from 2589 m depth on the Carlsberg Ridge in the Indian Ocean during deep-sea dredging. All fragments belong to a new genus and species, Indiellagen. n.ridgenensissp. n., a representative of the family Aulocalycidae described here. The peculiar features of this sponge, not described earlier for other Aulocalycidae, are: longitudinal strands present in several layers and epirhyses channelization.
