- An annotated check list of the Cicadomorpha and Fulgoromorpha (Hemiptera) of the Madeira and Salvages archipelagosPublication . Aguin-Pombo, Dora; Freitas, CarlosThe volcanic archipelagos of Madeira and Salvages located respectively at 635 km and 373 km offshore of the north eastern African coast are very rich in endemic species. These two archipelagos together with the Canary Ils and the archi pelagos of Cape Verde and Azores represent part of the Mediterranean hot spot which is considered the richest area in flora and fauna of Europe. To synthesize the knowledge on these groups, an annotated checklist of Cicadomorpha and Fulgoromorpha of the archipelagos of Salvages and Madeira is presented based on published literature including data on distribution and food plants. In addition 9 new species records are reported: Austragallia caboverdensis, Austragallia sinuata, Balclutha rufofascia, B. hebe, Cicadella viridis, Macrosteles sexnotatus, Recilia angusticeps, Tamaricella cf fas ciolata and Zyginidia lineata. The checklist comprises 79 species of 7 different families. Of these species 87% occur in Madeira and 10% in the Salvages archipelago. As a whole 27% are endemic to Madeira and 8% are endemic to Macaro nesia. Despite this diversity, knowledge of their habitats and food plants is still very scarce.
- Ants (Hymenoptera: Formicidae) of the Madeiran ArchipelagoPublication . Wetterer, James K.; Espadaler, Xavier; Wetterer, Andrea L.; Aguin-Pombo, Dora; Franquinho-Aguiar, António M.The subtropical Atlantic archipelago of Madeira is part of the Macaronesian biogeographic subregion. Absence of important mainland competitors and predators on Macaronesian islands has allowed the survival of many relicts of the subtropical biota that once inhabited the Mediterranean area. In the 19th century, however, two highly destructive exotic ant species, the big-headed ant (Pheidole megacephala) and the Argentine ant (Linepithema humile), invaded Madeira. Many authors have assumed that these invaders exterminated most or all native ants of Madeira, despite no research actually documenting such impact. In the present study, we compiled records and evaluated the native versus exotic status of all ant species collected in Madeira. We examined specimens of 27 ant species from Madeira: Cardiocondyla emeryi, Cardiocondyla mauritanica, Hypoponera eduardi, Hypoponera punc tatissima, Hypoponera sp. 1, Lasius grandis, Linepithema humile, Messor structor, Monomorium carbonarium, Monomorium pharaonis, Monomorium subopacum, Myrmecina graminicola, Paratrechina jaegerskioeldi, Paratrechina longicornis, Pheidole megacephala, Pheidole pallidula, Plagiolepis schmitzii, Pyramica membranifera, Solenopsis sp. 1, Solenopsis sp. 2, Strumigenys silvest rii, Tapinoma madeirense (new status), Technomyrmex pallipes, Temnothorax unifasciatus, Temnothorax wollastoni, Tetramorium bicarinatum, and Tetra morium caldarium. One previously reported species, Camponotus sylvaticus, we could not verify with specimens, but accept it was correctly identified, at least to genus. We determined that one ant taxon reported from Madeira is a junior synonym of another taxon present: Plagiolepis schmitzii madeirensis (= P. schmitzii, new synonymy). In addition, published records of eight ant taxa reported from Madeira appear to be misidentifications of other species present. Based on their known distribution and ecology, ten ant species (including the seven most common species) appear to be native to Madeira. Only one native ant species, T. wollastoni, has not been collected recently (1995 or later) in Madeira. Although exotic ants may have exterminated T. wollastoni, it seems likely that this species still survives.
- A bibliographic catalogue of the Cicadomorpha and Fulgoromorpha of North East Spain (Aragon)Publication . Aguin-Pombo, Dora; Freitas, Carlos; Alvaréz, Pedro A.; Bourgoin, ThierryThe knowledge of a large number of Iberian Peninsula Hemiptera such as Cicadomorpha and Fulgoromopha is still fragmentary. Nevertheless, these two groups are especially remarkable because many species are endemic to this region while others are pests and/or vectors of diseases to cultivated plants. Therefore, information on these Hemiptera is important not only for conservation purposes, but also necessary for agricultural pest management. Within Spain, Aragon -located in the northeast of the country- is especially interesting due to the great diversity of habitats, rich flora and the strategic geographic position. For this political re gion, a bibliographic catalogue of Cicadomorpha and Fulgoromopha is here compiled. The results show that 136 species of 12 of the 15 families present in Iberian Peninsula have been reported in Aragon in previous works. Of these species, 17 percent are en demic to Spain and 15 percent were never mentioned in previous catalogues or checklists for the whole Iberian Peninsula. These results although exciting are clearly insufficient if we consider that several hundreds of species should be expected in this area; clearly more work should be done.
- Case report: human dermatitis linked to Ornithonyssus bursa (Dermanyssoidea: Macronyssidae) infestation in PortugalPublication . Waap, Helga; Aguin-Pombo, Dora; Maia, Maria; Aguin-Pombo, DoraOrnithonyssus bursa (Berlese, 1888), also known as the tropical fowl mite, is a blood-feeding ectoparasite of domestic and wild birds. It is considered a serious pest to poultry in warm and tropical climates and has been reported to attack humans, causing gamasoidosis. Avian-mite dermatitis may be difficult to recognize and misdiagnosed as bites from other arthropods. The present report describes two cases of human dermatitis linked to O. bursa infestation. Both cases occurred in an apartment in a residential area in Oeiras, Portugal, where two members of the same family presented with pruritic erythematous skin eruptions disseminated over their body over a period of 4 months. The lesions were located mostly in the pelvic, gluteal, coccygeal, and perineal regions, and also on the neck, wrists and torso. On inspecting the mattresses and the covers of the bedrooms, three mites ~1 mm long by 0.5 mm wide were found. The three specimens were identified as O. bursa. Investigations tracing back the source of infestation, revealed that the mites were carried over from chickens raised 45 km away (Sesimbra, Setúbal) that, after being slaughtered for consumption, had been transported by car to the apartment in Oeiras. The chickens were farmed in an open backyard henhouse that allowed free access to several species of wild birds, including pigeons (Columba livia), turtle doves (Streptopelia decaocto), and sparrows (Passer domesticus). Recent reports suggest that O. bursa may be established in Mediterranean countries, increasing the risk of gamasoidosis. This is the first record linking O. bursa infestation of chickens with human dermatitis in continental Portugal. More research is needed to assess the extent of poultry infestation and evaluate the possible implications for the poultry industry, as well as for human health in Portugal.
- Catálogo de los hemípteros Cicadomorpha y Fulgoromorpha de AragónPublication . Aguin-Pombo, Dora; Freitas, Carlos; Álvarez, Pedro A.; Bourgoin, Thierry: Este es el primer catálogo bibliográfico realizado sobre los grupos de hemípteros Cicadomorpha y Fulgoromorpha de Aragón. Se han recogido los datos publicados desde Linneo hasta la actualidad. En total han sido citadas 136 especies en 46 trabajos realizados por 36 autores. Estas especies representan 12 de las 15 familias conocidas de la Península Ibérica, siendo un 17 por ciento de las especies endémicas de España y un 15 por ciento especies que nunca habían sido citadas de la Península Ibérica, ni en catálogos ni en listas de especies publicadas previamente. La fauna de Huesca, con 82 especies, es la mejor conocida de las tres provincias.
- Collembola of the Cavalum and Landeiro Caves (Madeira, Portugal)Publication . Baquero, Enrique; Arbea, Javier I.; Nunes, Élvio; Aguin-Pombo, Dora; Mateos, Eduardo; Jordana, Rafael; Aguin-Pombo, DoraThe cave fauna of the Macaronesian archipelagos is rich in endemic species. Unlike the Azores and the Canary Islands, the cave fauna of the Madeira archipelago is little known. The only two cave complexes studied, Machico and São Vicente, lack protection measures. São Vicente is seriously threatened because it is being exploited for touristic purposes, while the Machico complex, the only one in its natural state, is open to the public but without any control. The importance of the conservation of this cave fauna is indisputable. So far, of the 13 cavernicolous species recorded, two of them—genus Centromerus—are critically endangered. Apart from occasional sampling, no monitoring study has ever been carried out. The aim of this work has been to make a species checklist of the cave fauna of the Machico complex, the least studied so far. For this purpose, during 2001–2002, a monitoring study was carried out using traps and manual collections in the lava tubes of Landeiros and Cavalum (I, II, III). Fourteen species of springtails were recorded. Of these, four are new species, Neelus serratus Jordana & Baquero sp. nov., Coecobrya decemsetosa Jordana & Baquero sp. nov., Coecobrya octoseta Jordana & Baquero sp. nov., and Sinella duodecimoculata Jordana & Baquero sp. nov., and one is a new record for the archipelago, Lepidocyrtus curvicollis Bourlet, 1839.
- Comparative cytogenetics of Auchenorrhyncha (Hemiptera, Homoptera): a reviewPublication . Kuznetsova, Valentina; Aguin-Pombo, DoraA comprehensive review of cytogenetic features is provided for the large hemipteran suborder Auche norrhyncha, which currently contains approximately 42,000 valid species. This review is based on the analysis of 819 species, 483 genera, and 31 families representing all presently recognized Auchenorrhyn cha superfamilies, e.i. Cicadoidea (cicadas), Cercopoidea (spittle bugs), Membracoidea (leafhoppers and treehoppers), Myerslopioidea (ground-dwelling leafhoppers), and Fulgoroidea (planthoppers). History and present status of chromosome studies are described, as well as the structure of chromosomes, chro mosome counts, trends and mechanisms of evolution of karyotypes and sex determining systems, their variation at different taxonomic levels and most characteristic (modal) states, occurrence of partheno genesis, polyploidy, B-chromosomes and chromosome rearrangements, and methods used for cytoge netic analysis of Auchenorrhyncha.
- Differences in wing venation between parthenogenetic and bisexual species of Empoasca leafhoppers from Madeira IslandPublication . Aguin-Pombo, Dora; Valido, Lia; Sousa, Fábio; Arraiol, AnabelaEmpoasca is a large worldwide distributed genus of about 400 species many of which are pests to agricultural plants. Species of Empoasca are bisexual but recently three parthenogenetic morphotypes (A, B and C) of various degrees of polyploidy have been reported from Madeira Island. Females of Empoasca are difficult to identify because they show insufficient morphological diag nostic characters. In this work, we evaluate the utility of wing venation pattern for the identification of the three bisexual and three unisexual taxa of Empoasca present in Madeira. Our main motivation is to test whether the wing venation pattern is a stable char acter and to assess whether it could be suitable to develop an identification key for females of taxa present in Madeira Island. We analysed 107 categorical characters of wing patterns and vein shape in the forewings and hind wings of 677 females. The results showed that wing venation may provide useful characters to identify species of Empoasca despite a considerable amount of in traspecific variation. The variation within each species in wing pattern was analysed and several modifications in vein number such as additional or missing veins and in vein shape as bifurcations or incomplete veins are reported.
- The drosophilids (Diptera: Drosophilidae) from a Laurisilva patch in Madeira with two new records for this islandPublication . Aguin-Pombo, Dora; Boieiro, M.; Gonçalves, Y.; Menezes, D.; Aguin-Pombo, D.; Capela, R.The drosophilid fauna of Madeira consists of 20 species from 6 different genera, including one endemic species, Drosophila madeirensis Monclús, 1984. In spite of several studies on Madeira drosophilids, little is known on the spatial distribution and phenology of most species, particularly of those associated to the native laurel forest. In this study, the drosophilid fauna of a Laurisilva patch was studied over an 18-month period in Chão da Ribeira (Seixal, northern Madeira) using several sampling techniques. As a result of this study, seventeen species were recorded including two new records for Madeira: Drosophila phalerata (Meigen, 1830) and Lordiphosa n. sp., a new unnamed species. The current knowledge of Madeiran drosophlid fauna is also briefly discussed.
