New alien insect pests to Portugal on urban ornamental plants and additional data on recently introduced species

The spread of invasive pests is an important topic in pest control and early detection is crucial for containment of invasive aliens. In this study the results of recent surveys on alien insects of ornamental urban plants in Portugal are reported. Overall, 13 alien species associated with allochthonous ornamental plants were recorded. Seven of these pests are new to the Portuguese fauna: Tinocallis kahawaluokalani (Kirkaldy); Illinoia liriodendri (Monell); Appendiseta robiniae (Gillette) (Hemiptera: Aphididae); Acizzia jamatonica (Kuwayama) (Hemiptera: Psyllidae); Dasineura gleditchiae (Osten Sacken); Obolodiplosis robiniae (Haldeman) (Diptera: Cecidomyiidae); and Phytoliriomyza jacarandae Steyskal & Spencer (Diptera: Agromyzidae). Additional distribution data are also provided for other recently introduced alien pests in Portugal: Myzocallis (Lineomyzocallis) walshii (Monell) (Hemiptera: Aphididae); Platycorypha nigrivirga Burckhardt; Glycaspis brimblecombei Moore (Hemiptera: Psyllidae); Calophya schini Tuthill (Hemiptera: Calophyidae); Corythucha ciliata (Say) (Hemiptera: Tingidae); and Lantanophaga pusillidactylus (Walker) (Lepidoptera: Pterophoridae). Three species in particular (Illinoia liriodendri, Obolodiplosis robiniae and Phytoliriomyza jacarandae) were not previously found in the Iberian Peninsula. Details on current distribution, host plants and biological remarks are given for each species. Possible origin areas, pathways and impacts are also discussed.     

Revision of the Indo‐African Pachycerus Schoenherr, 1823, with a description of four new species (Coleoptera: Curculionidae: Lixinae)

The Indo‐African species of the genus Pachycerus (Curculionidae: Lixinae: Cleonini) are revised. The identification of Cleonus senegalensis Gyllenhal, 1834 is discussed, its holotype rediscovered and the synonymy between C. senegalensis and Ammocleonus hieroglyphicus (Olivier, 1807) is confirmed. A neotype is established for Pachycerus opimus (Gyllenhal, 1834). Lectotypes for Pachycerus vestitus (Fåhraeus, 1834), Pachycerus badeni (Faust, 1888), and Pachycerus sellatus Faust, 1904 are designated. Pachycerus sahelicus sp. nov. (type locality: Senegal, Bambey), Pachycerus hippali sp. nov. (type locality: Saudi Arabia: Jeddah, Taif), Pachycerus barclayi sp. nov. (type locality: southern India: Manapparai), and Pachycerus simonae sp. nov. (type locality: Morocco, Western Sahara, Cap Boujdour) are described. Some remarks on taxonomy and biogeography of the species are added.     

Holotrich Ciliates from the Stomach of Hippopotamus amphibius, with Descriptions of Two New Genera and Four New Species

SYNOPSIS. Holotrich ciliates from the stomach contents of Hippopotamus amphibius are described, including details of their infraciliature. They are placed in 4 families: subclass Holotrichia, order Gymnostomatida, suborder Rhabdophorina, family Buetschliidae: Blepharozoum binucleatum n.sp., Cucurbella vivax n.g., n.sp.; order Trichostomatida, family Plagiopylidae: Paraplagiopyla kiboko n.g., n.sp.; family Paraisotrichidae: Paraisotricha minuta Hsiung, 1930; family Blepharocorythidae: Charonina hippopotami n.sp. Paraisotricha minuta appears identical to the form found in the cecum and colon of the horse; Blepharozoum binucleatum, Cucurbella vivax and Charonina hippopotami also approach species found in the digestive tract of Equidae. By contrast, Paraplagiopyla kiboko resembles species that are free-living or are commensal in the digestive tract of Echinodermata.     

Revision of the genus Pugillaria Iredale, 1924 (Mollusca: Panpulmonata: Siphonariidae)

The species of Pugillaria Iredale, 1924 are revised and redescribed. Having not been described adequately, the type species Siphonaria stowae Verco, 1906 of the genus Pugillaria has remained confused and hence the status and validity of the genus uncertain. Previous assessments of S. stowae were based solely on the interpretation of shell and radula characteristics. Three species of Pugillaria are described, two are new and all are endemic to Australia. Pugillaria species are amongst the smallest known members of the Siphonariidae. They are very uncommon and have probably been overlooked as juveniles of larger co-existing siphonariid or patelliform species in collections. They have a distinctive shell morphology, reproductive system and radula. The genus is differentiated from other siphonariid genera (Siphonaria Sowerby, 1823, Benhamina Finlay, 1927 and Williamia Monterosato, 1884) as well as the coexisting Trimusculus Schmidt, 1818 (Ellobiidae).

Materials for the fungus flora of Japan (49)

Two interesting microfungi are described as new to Japan:Talaromyces galapagensis (anam.Penicillium galapagense), isolated from soil in Shizuoka; andPenicillium megasporum, isolated from marine sludge in Nagasaki. Some observations are recorded, particularly on ascomatal initials ofT. galapagensis, which are similar to those described forTalaromyces flavus.(48): Kaneko, S., Mycoscience 36: 359–360, 1995.     

Two new myrmecophilous species of the genus Scutacarus (Acari: Prostigmata: Scutacaridae) with world keys to related species groups

In a survey on heterostigmatic mites (Acari: Prostigmata: Heterostigmata) associated with insects including ants in northwestern Iran, two new species of myrmecophilous mites of the genus Scutacarus (Acari: Scutacaridae) were found. They are S. shajariani sp. nov. phoretic on Tetramorium sp. (Hymenoptera: Formicidae) and S. ebermanni sp. nov. phoretic on Messor sp. The mentioned new species belong to groups of species with reduced setae e and h₂, and no setae 4b, respectively. These two new species are described and illustrated, and world keys are provided for respective species groups.     

The cladistics and biology of the Callajoppa genus-group (Hymenoptera: Ichneumonidae, Ichneumoninae)

A cladistic analysis is presented for the genera of the former ichneumonine tribe Trogini. The tribe Heresiarchini is paraphyletic with respect to the Trogini, and so maintaining Trogini as a separate tribe is unsatisfactory. Within Heresiarchini, the following changes are made: (a) the subtribes Apatetorina and Heresiarchina are referred to as the Apatetor and Heresiarches genus‐groups, (b) the genera of the paraphyletic subtribe Protichneumonina are treated as incerta sedis within Heresiarchini, and (c) the Trogini are referred to as the Callajoppa genus‐group, with the former subtribe Trogina referred to as the Trogus subgroup. Thirty‐five genera are recognized as valid within the Callajoppa genus‐group. Catadelphops, Catadelphus, Cobunus, and Facydes are transferred to this group; Holojoppa is removed and is incertae sedis within Heresiarchini. Three new synonyms are proposed: Araeoscelis and Cryptopyge are junior synonyms of Macrojoppa, and Neamblyjoppa is a junior synonym of Catadelphops. Trogus latipennis Cresson is transferred to Pedinopelte from Macrojoppa, and Trogus mactator Tosquinet and its related species (T. bicolor Radoszkowski, T. heinrichi Uchida, and T. tricephalus Uchida) are transferred to Holcojoppa. Tricyphus is redefined and a neotype is designated for Tricyphus cuspidiger Kriechbaumer, the type‐species of the genus. Thirteen new genera are described (authorship of all is Wahl & Sime): Charmedia (type‐species: Charmedia chavarriai Wahl & Sime, sp. n.) , Daggoo (type‐species: Daggoo philoctetes Wahl & Sime, sp. n.), Dothenia (type‐species: Dothenia hansoni Wahl & Sime, sp. n.), Humbert (type‐species: Humbert humberti Wahl & Sime, sp. n.), Laderrica (type‐species: Laderrica feenyi Wahl & Sime, sp. n.), Mokajoppa (type‐species: Tricyphus respinozai Ward & Gauld), Metallichneumon (type‐species: Metallichneumon neurospastarchus Wahl & Sime, sp. n.), Myocious (type‐species: Myocious orientalis Wahl & Sime, sp. n.) , Quandrus (type‐species: Trogus pepsoides Smith, transferred from Callajoppa), Queequeg (type‐species: Gathetus flavibasalis Uchida, transferred from Neofacydes), Saranaca (type‐species: Trogus elegans Cresson; includes Trogus apicalis Cresson, Tricyphyus ater Hopper, and Tricyphus floridanus Heinrich), Tashtego (type‐species: Tashtego janzeni Wahl & Sime, sp. n.), and Xanthosomnium (type‐species: Xanthosomnium froesei Wahl & Sime, sp. n.). A key to the genera of the Callajoppa genus‐group is provided. The evolution of biological traits within the Callajoppa genus‐group is discussed with reference to the elucidated phylogeny. The groundplan biology is parasitism of Sphingidae, with oviposition into a host pupa/prepupa. There have been two transitions to butterfly parasitism within the Trogus subgroup: one a transition to Papilionidae (followed by a switch to Nymphalidae at Psilomastax) and the other to Nymphalidae (followed by a switch to Papilionidae within Macrojoppa). ©2002 The Linnean Society of London.

Utilization of food resources by small and medium‐sized mammals in the Monte Desert biome,Argentina

Theoretical models of species coexistence between desert mammals have generally been based on a combination of food and microhabitat selection by granivorous rodents. Although these models are applicable in various deserts of the world, they cannot explain resource use by mammals in Neotropical deserts. The present study examines diet composition in a mammal assemblage in the Monte desert, Argentina. The results show that two main strategies are used by these mammals: medium‐sized species (hystricognath rodents: Dolichotis patagonum, Lagostomus maximus, Microcavia australis and Galea musteloides; and an exotic lagomorph: Lepus europaeus) are herbivores, whereas small‐sized species (a marsupial: Thylamys pusillus; and sigmodontine rodents: Graomys griseoflavus, Akodon molinae, Calomys musculinus, Eligmodontia typus) are omnivorous. Small mammals also show a tendency towards granivory (C. musculinus), insectivory (A. molinae and T. pusillus) and folivory (G. griseoflavus).     

Fatty acid biomarker ratios—suitable trophic indicators in Antarctic euphausiids?

Fatty-acid biomarkers are frequently used for the identification of trophic relationships among marine zooplankton. We have evaluated the suitability of five fatty-acid ratios [16:0/16:1(n-7), 16:1(n-7)/18:4(n-3), 18:1(n-9)/18:1(n-7), 20:5(n-3)/22:6(n-3), PUFA/SFA] that have been proposed as trophic indicators in the literature. Total lipid content and fatty-acid composition were determined in four Antarctic euphausiid species (Euphausia superba, E. frigida, E. triacantha, Thysanoessa macrura). There is a significant relationship between the lipid content and most of these ratios in the investigated euphausiids. Only the 16:1(n-7)/18:4(n-3) ratio exhibits no clear relationship to total lipids. Further exceptions occur in E. triacantha: the 18:1(n-9)/18:1(n-7) and the 20:5(n-3)/22:6(n-3) ratios are not correlated to the lipid content in this species. There is a weaker correlation between the fatty-acid ratios and the total lipid content in E. superba larvae than in the postlarvae, indicating a stronger dietary influence on the lipids of the younger stages. We conclude that those fatty-acid ratios that strongly depend on an animals total lipid content (particularly PUFA/SFA), are only of limited use as trophic indices, since total lipid content may vary greatly with factors (such as reproductive processes) that are unrelated to specific feeding preferences.     

Cover plus: ways of measuring plant canopies and the terms used for them

Aim: To clarify the concepts and terms that have been used in recording plant canopies and the methods used for measuring them. Concepts: The concepts considered are cover, top cover, repeated cover, number of layers, proportion of repeated cover and leaf area index (LAI). Variants include canopy cover, basal area and leaf area density. Other terms have been used in the past, some are now ambiguous and some are counter‐intuitive. Measurement: Cover and its related concepts can be measured by point intercept, line intercept, angle sampling, charting and image analysis, canopy transmittance, complete enumeration, clipping and allometry. The common procedure of adding the cover of individual species to calculate a “total cover” is invalid: a nonsense number is produced. Other measures of abundance: Cover‐abundance, density, frequency, biomass and calorific values can also be used to measure abundance. They are related to cover. Especially, shoot frequency at a point is cover (the point intercept method). Subjective estimates: There are severe problems with cover‐abundance scales, such as that of Braun‐Blanquet. Estimation of abundance “by eye”, by “informed guess”, etc. has too often compromised results in vegetation science.

The mito::mKate2 mouse: A far‐red fluorescent reporter mouse line for tracking mitochondrial dynamics in vivo

Mitochondria are incredibly dynamic organelles that undergo continuous fission and fusion events to control morphology, which profoundly impacts cell physiology including cell cycle progression. This is highlighted by the fact that most major human neurodegenerative diseases are due to specific disruptions in mitochondrial fission or fusion machinery and null alleles of these genes result in embryonic lethality. To gain a better understanding of the pathophysiology of such disorders, tools for the in vivo assessment of mitochondrial dynamics are required. It would be particularly advantageous to simultaneously image mitochondrial fission‐fusion coincident with cell cycle progression. To that end, we have generated a new transgenic reporter mouse, called mito::mKate2 that ubiquitously expresses a mitochondria localized far‐red mKate2 fluorescent protein. Here we show that mito::mKate2 mice are viable and fertile and that mKate2 fluorescence can be spectrally separated from the previously developed Fucci cell cycle reporters. By crossing mito::mKate2 mice to the ROSA26R‐mTmG dual fluorescent Cre reporter line, we also demonstrate the potential utility of mito::mKate2 for genetic mosaic analysis of mitochondrial phenotypes.
