Summary

It is accepted that the genus Ortleppina Schulz, 1927, is a synonym of the genus Heliconema Travassos, 1919.

Five valid species of Heliconema are recognized: H. heliconema, H. ahiri, H. baylisi, H. brevispiculum and H. longissima.

A new species, H. baylisi is described, and H. heliconema, H. brevispiculum and H. longissima are redescribed.  相似文献

Summary

The genus Helixotionella is introduced for three species of spirally budded, free-living, lunulitiform bryozoans from Australia, H. spiralis (Chapman), H. rubra (Bretnall) and H. scutata sp. nov. H. spiralis, the type species, has a fossil history extending from the Upper Oligocene of Victoria, but like H. scutata, has been found to occur in Recent samples from Western Australia. H. rubra is known only from the Recent of New South Wales. All species have minute colonies and the majority of specimens has been revealed only after detailed examination of very fine fractions of bottom sediments, which themselves include a high proportion of bryozoan skeletal material.  相似文献

Summary

Haemoproteus majoris, originally described by Laveran from Parus major in France but hitherto denied specific status, is redescribed from P. major in Great Britain and designated a valid species. H machlolophi de Mello (1935) of P. xanthogenys in India is considered to be a synonym of H. majoris. The occurrence and distribution of haemoproteids in other Paridae is briefly discussed.  相似文献

Summary

A new species of Halectinosoma Lang, 1948, H. pterinum sp. nov. is described from the Isle of Man. Examination of this and some other species of the genus under high magnifications suggests that the diagnosis of the genus may have to be modified.  相似文献

Summary

Three species of Trichomycetes were found in New Zealand Austrosimulium (Austrosimulium) Tonnoir larvae; Harpella melusinae Léger &; Duboscq, Smittium sp. and an unidentified genistellacean. All three are new Southern Hemisphere records. The commonest species, H. melusinae, was found in seven species of Austrosimulium being particularly abundant in A. (A.) tillyardianum Dumbleton. In a sample of A. (A.) tillyardianum examined from the Wainui Valley Stream, Canterbury, it was found that H. melusinae was able to infect and produce trichospores in second instar larvae, and that the number of thalli and trichospores per larva increased in each subsequent instar.  相似文献

Summary

A re-examination of Haplomunna Richardson (1908) reveals a close relationship between this genus and Munella Bonnier (1896), Abyssaranea Wilson &; Hessler (1974) and Thylakogaster ibid. As a consequence, a new family, Haplommunidae, is erected to contain these four genera. The systematic problems with this new grouping, its relation to the Dendrotionidae, and some peculiarities of its members are discussed. A key and the geographical ranges of the four genera are included. A generic diagnosis for Haplomunna is given, and H. caeca (Richardson, 1905) and H. hubbsi, sp. nov. are described.  相似文献

Summary

The frog Heleioporus (Anura: Leptodactylidae) calls from a burrow. This paper examines the acoustic properties of the burrow by experimentally actuating plaster casts taken from five species: H. eyrei, H. psammophilus, H. albopunctatus, H. inornatus and H. barycragus. These findings are correlated with the properties of both natural calls of the frogs from the burrow and calls induced from the frog outside of the burrow. The morphology of the burrow enhances the principal frequency component of the call by resonance. Frogs call from a slight bulge beneath the burrow entrance. This calling site corresponds to the optimum position for generating a sound pressure maximum within the burrow. This was determined experimentally in an artificially constructed burrow with a complex internal sound source. In addition to optimizing the acoustic properties of the burrow the frog, in this position, has an open visual field from the burrow entrance. We conclude that the burrow system may compensate for the lack of a vocal sac in these frogs.  相似文献

ABSTRACT

The host–parasitoid relationship and species identity of aquatic parasitoids of two damselflies Coeliccia cyanomelas (Platycnemididae) and Psolodesmus mandarinus dorothea (Calopterygidae) from Fushan and Lienhuachih in Taiwan were studied using morphological characters and DNA barcoding sequences. The parasitoids reared from the damselflies’ eggs, and the field-collected parasitoids, were morphologically identified as Hydrophylita emporos (Trichogrammatidae), a recently described parasitoid of the damselfly P. m. mandarinus from Northern Taiwan. The CO1 (cytochrome c oxidase I) gene tree supported the identification as H. emporos, as well as all parasitoid samples from C. cyanomelas, P. m. dorothea and P. m. mandarinus. The sampled H. emporos populations did not differ genetically despite their different host associations. However, some genetic differences were found between H. emporos populations from Northern and Central Taiwan, indicating that the dispersal of H. emporos may be limited by geographical distances. Our results suggest that H. emporos can parasitise not only closely related sister subspecies, P. m. mandarinus and P. m. dorothea, but also phylogenetically distant species of another damselfly family, C. cyanomelas. This is the first record of multiple damselfly hosts for the aquatic parasitoid genus Hydrophylita. This finding implies that the host range of H. emporos and congeneric species may be broader than previously thought.  相似文献

ABSTRACT

A phylogenetic taxonomy of the gekkonid genus Hemiphyllodactylus based on molecular, morphological, and ecological data recovered 28 species, including three new species from the upland regions of the Shan Plateau in eastern Myanmar. Hemiphyllodactylus linnwayensis sp. nov. is a forest-adapted species that may also be a human commensal and H. montawaensis sp. nov. and H. tonywhitteni sp. nov. are karst forest-adapted species. The discovery of three new species from montane regions in eastern Myanmar extends the distribution of a larger monophyletic group of Hemiphyllodactylus westward to the eastern edge of the Ayeyrawady Basin through a series of semi-contiguous, parallel mountain ranges originating in western China and northern Thailand. The discovery of the karst forest-adapted H. montawaensis sp. nov. and H. tonywhitteni sp. nov. further emphasizes the unrealized herpetological diversity endemic to karst ecosystems and the need for increased field work throughout such habitats in South-East Asia.

Summary

The behaviour and feeding habits of T. biguttatus, T. fraternus, T. taeniola. T. gratus and H. decora were studied in the vicinity of a resting cattle herd. The observations could be substantiated by experiments with flies on restrained animals and an examination of 11 189 Tabanidae in regard to presence and size of fresh blood meals.

By relating these findings to the principles of mechanical transmission, the small Tabanidae T. gratus and H. decora did not show the expected behaviour of potential vectors. Of the large species, T. biguttatus and T. fraternus did not qualify on the basis of their feeding habits. It was concluded that T. taeniola fulfilled, in regard to behaviour and feeding habits, all requirements for mechanical disease transmission under natural conditions.  相似文献

Summary

The biological relationships of intertidal bryozoans from northern New Zealand are recorded. Bryozoans were found to be food organisms for echinoids, starfish, brittle-stars, chitons and opisthobranchs. Space competition between bryozoans and sessile organisms is discussed. Among opposing bryozoan colonies there are five growth responses that may be exhibited. Of the sessile organisms studied on the shore, bryozoans and Spirorbis occupied the most space. The association between Hippopodinella adpressa and gastropod shells is discussed with reference to current opinions regarding bryozoan-mollusc associations. It is concluded that the attractive factor to H. adpressa larvae is a calcareous substrate but that pagurid tenancy of gastropod shells may have reinforced the evolutionary forces responsible for the association with shells.  相似文献

Summary

The Philippine cruise of the U.S. Fisheries Steamer Albatross 1907–10 collected 61 species of spider crabs from the Philippine Islands bringing the total number of species known from the area to 71; 28 new species were described by Rathbun and the present report records 19 species not previously known from the area; included are nine widespread Indo-west Pacific forms, four previously known from Japan and four Indian Ocean species.

Hyastenus sebae White is renamed H. whitei and the former name is applied to H. oryx A. Milne Edwards. Hyastenus tuberculosus Rathbun is confirmed as a synonym of H. convexus Miers, Platymaia remifera Rathbun is reduced to synonomy with P. wyvillethomsoni Miers and Chorilia sphenocarcinoides Rathbun is transferred to the genus Sphenocarcinus.

The majority of species (51) occur around the central and southern islands of the archipelago and most of these (35 speciesl occur at varying depths on the continental shelf. Twelve species occur intertidally and 21 species are known from depths over 100 fms, some occurring as deep as 800 fms.

The spider crab fauna is clearly part of the Indo-west Pacific, 25 species being widespread ones; 26 species are shared with Japan, 24 with Australia and 31 with the Indian Ocean. However, 20 species appear to be confined to the Philippine Islands. The relationships of the Philippine fauna with that of the rest of Indonesia is not yet clear  相似文献

ABSTRACT

The natural history and morphology of the later instars and pupa of the metalmark butterfly Pachythone xanthe H. Bates are described and illustrated for the first time. The caterpillars are myrmecophilous and carnivorous, feeding on scale insects (Hemiptera: Coccoidea) tended by Azteca cf. chartifex Forel (Formicidae: Dolichoderinae) ants and appear to be physically shielded from potential ant attacks by a carapace-like body that protects the head and appendages. In addition, the larvae present several types of specialised setae and ant-organs such as perforated cupola organs, glandular openings and functional tentacle nectary organs that may be related to appeasement of aggressive ant behaviour. Our results reveal the first detailed life cycle data for the Pachythonina subtribe and record a new independent origin of carnivory in Riodinidae.  相似文献

Summary

Seven species of armoured scale insects infest avocado in Israel. Hemiberlesia lataniae (Signoret) and Abgrallaspis cyanophylli (Signoret) are the most abundant. Avocado seedlings become infested in the nurseries, thus serving as important sources for commercial grove contamination. Because larger diaspidid populations develop at the inside of the trees (as compared to their outside), and at height levels of 1·5–2·0 m (compared to 5·0–6·0 m), these regions were regularly sampled. Equal-area examinations of bark and leaf revealed that H. lataniae prefers the bark, A. cyanophylli the leaves. The populations of both scales undergo similar annual cycles on leaves, peaking during winter, ebbing in early summer. The specific settling pattern of most diaspidids on avocado leaves were figured. The somewhat-different settling sites of H. lataniae and A. cyanophylli apparently preclude competition when low numbers are present, but the former may be partially inhibited when large populations develop. Several predators and hymenopterous parasitoids attack the diaspidids, the parasitoids being most active in early summer. No economic injury to local avocado fruit by armoured scale insects has been reported in recent years. The reasons for this are discussed, and it is recommended that the present situation, in which no insecticides are used in avocado groves, be maintained.  相似文献

ABSTRACT

Two new pill millipede species, namely Hyleoglomeris hoanglien sp. nov. and H. fanxipan sp. nov., are described from high elevations (approximately 2,800–2,900 m) of the Hoang Lien National Park, northern Vietnam. A new species, H. hoanglien sp. nov. is clearly distinguished by the telopods being short, stout and incrassate, femora strongly condensed, tibia without modifications, syncoxital lobe bifid trapeziform, and syncoxital horns with an apical seta and a spine. Hyleoglomeris fanxipan sp. nov., is diagnosed by the telopods being long and robust, tibia without modifications, syncoxital lobe roundly trapeziform, and syncoxital horns truncated at tip. COI-based DNA barcodes of the two species are also provided for the first time in the genus Hyleoglomeris. The K2P genetic distance between the two new species is 0.148. In addition, an identification key to the Vietnamese Hyleoglomeris species is also provided.

ABSTRACT

Six new species of Orasema are described. Four species are placed into a newly recognised lasallei species group: Orasema lasallei sp. nov. (Costa Rica, Honduras, Mexico, Nicaragua), O. janzeni sp. nov. (Costa Rica), O. peckorum sp. nov. (Brazil) and O. vasquezi sp. nov. (Colombia). One species is placed in the wayqecha group, Orasema masneri sp. nov. (Ecuador). One other species is currently unplaced to species group, O. longinoi sp. nov. (Costa Rica). Orasema lasallei was taken from a nest of Pheidole vorax (Fabr.) and an undescribed species near O. longinoi from a nest of Pheidole dossena Wilson (Myrmicinae). The morphology of the digitate labrum is discussed with respect to other Eucharitidae.  相似文献

ABSTRACT

We examined genetic relationships among individuals and populations of the species Holbrookia lacerata, the spot-tailed earless lizard, using whole mitochondrial genomes. Lizards were collected from south, central and west Texas. We found significant amounts of genetic structure among populations and evidence of two major reciprocally monophyletic groups of spot-tailed earless lizards in Texas. Holbrookia lacerata lacerata occurs on the Edwards Plateau and adjacent regions of West Texas north of the Balcones Escarpment, while Holbrookia lacerata subcaudalis occurs in South Texas and adjacent Mexico south of the Balcones Escarpment. These two recognised subspecies correspond to the two clades we discovered. Holbrookia l. lacerata occupies much of its historical range at sometimes high population densities, while populations of H. l. subcaudalis appear to be highly fragmented based on recent observations compared to their historical range.  相似文献
