Updated checklist of the mosquitoes (Diptera: Culicidae) of Croatia

Improvement of morphological and molecular identification methods allows the detection of new species of mosquitoes. The mosquito fauna of Croatia currently includes 52 species, belonging to eight genera, including Anopheles (12 species), Aedes (24 species), Coquillettidia (one species), Culex (seven species), Culiseta (six species), Orthopodomyia (one species), and Uranotaenia (one species). This is an updated checklist, which includes five new species found in Croatian mosquito fauna. Two of these are invasive mosquito species, Aedes albopictus (Skuse, 1895) and Aedes japonicus (Theobald 1901), which are spreading across Europe and Croatia. The other three species, Culex laticinctus (Edwards 1913), Culex torrentium (Martini 1925), and Anopheles daciae (Linton, Nicolescu & Harbach 2004) are autochthonous species which haven't been recorded so far. Since there are several more invasive species spreading across Europe, we assume that this is not the final list.

Systematic revision of the yucca moths in the Tegeticula yuccasella complex (Lepidoptera: Prodoxidae) north of Mexico

The yucca moths (Tegeticula and Parategeticula) are of great importance in studies of coevolution because of their obligate mutualism with their yucca hosts. Historically, three species of Tegeticula have been recognized. One of them, T. yuccasella, has been regarded as the pollinator of all but two yucca species, but morphological, molecular and biological data show that this is a large complex of monophagous and oligophagous species that differ greatly in their biology. It also includes derived ‘cheater’ species that do not pollinate their hosts and oviposit into fruits rather than flowers. Here the yuccasella complex north of Mexico is revised. The nominotypic pollinator species yuccasella is redescribed, and ten new pollinator species described: altiplanella, baccatella, carnerosanella, cassandra, elatella, maderae, mojavella, rostratella, superficiella and treculeanella. Two non-pollinating cheater species are recognized. One such species originally misidentified as a Prodoxus species, then synonymised with yuccasella, is re-erected as the non-pollinating intermedia. In addition, the new non-pollinator species corruptrix is described.     

New species of alderfly genus Sialis (Megaloptera: Sialidae) from China and Vietnam,with a key to species of Sialis from Asia

The alderfly genus Sialis is the most species‐rich group of the family Sialidae. However, discovery of new Sialis species is becoming difficult because of previous good faunal exploration. In this paper, we describe two new Sialis species from the southern part of East Asia, S. australis and S. jiyuni, based on materials from historical and recent collections. These two species are closely related to the insular species S. kumejimae and are among the early diverged species within Sialis. Presently, 32 species of Sialis are recorded from Asia. A key to all the Sialis species from Asia is provided.     

Neotypification of the genusTrichosporon

The currently accepted type species of the genusTrichosporon Behrend isT. beigelii. This species has formerly been regarded as identical toT. cutaneum. However, these fungi are now known to represent separate species with different ecology. The first species described inTrichosporon wasT. ovoides, an agent of human white piedra. A neotype strain is designated for this species, while a lectotype strain is indicated forT. cutaneum. The nameT. beigelii is considered as doubtful and consequently cannot be maintained.     

Comparing longevity of Pseudacteon species of different sizes: effect of sugar feeding

Sugar feeding is known to enhance lifespan in many parasitoid species. Several species of phorid flies in the genus Pseudacteon (Diptera: Phoridae) have been introduced in the Southern U.S.A. for the biological control of imported fire ants of Solenopsis species (Hymenoptera: Formicidae). Pseudacteon species are short‐lived flies and little is known about their nutritional ecology. Results from previous studies in our laboratory show that one of the introduced species, Pseudacteon tricuspis Borgmeier, is capable of feeding on sugar sources with a significant increase in lifespan. However, in Pseudacteon phorid flies, the degree to which sugar feeding can enhance the lifespan of other species is not clear, nor is it known whether there is a relationship between body size and longevity. In the present study, the effect of sugar feeding on the survival of three phorid fly species of different body sizes, Pseudacteon cultellatus Borgmeier, Pseudacteon curvatus Borgmeier and Pseudacteon obtusus Borgmeier, is investigated. For all three species, flies continuously provided with 40% or 20% sucrose solution live longer than individuals provided water only or 40% sucrose solution only on the first day of adult life. However, the degree to which sugar feeding enhanced longevity varies by species and is highest for P. obtusus. The data also indicate that longevity in Pseudacteon phorid flies is related to body size: the largest species (P. obtusus) lives significantly longer than the smaller species (P. cultellatus and P. curvatus). These results suggest that adults of all three Pseudacteon species are capable of feeding on sucrose solution and that sugar feeding can enhance their longevity. The significance of these results is discussed in relation to the field performance of Pseudacteon phorid flies as biological control agents of imported fire ants.     

An update on the status of native and exotic freshwater fishes of Italy

An updated, corrected checklist of both native and established alien freshwater fish species in Italy is given based on molecular, morphological and biogeographical data. Some 12 native species, reported as conspecific with transalpine species in official Italian ichthylogical literature, are in fact endemics. Previous taxonomic confusion has resulted in the introduction of several alien species, either with official stockings or mixed in as impurities. Rehabilitated species include the cyprinids Scardinius hesperidicus, Scardinius scardafa and Telestes savigny from northern Italy, as well as Squalius ruffoi and the Telestes comes from southern Italy. Squalius albus is a junior synonym of S. squalus. The endemic gudgeon, previously assigned to the genus Romanogobio, is returned to the genus Gobio (G. benacensis). Phoxinus lumaireul is a junior synonym of P. phoxinus. Among the Salmonidae, Salmo cenerinus is a junior synonym of S. marmoratus, while Salmo farioides represents the trout species of the Adriatic lineage for which a neotype is designated. Thymallus aeliani represents the endemic lineage of grayling of the Adriatic populations. The esocid Esox cisalpinus is an endemic pike species and Esox flaviae is a junior synonym; the extensive exportation as well as the presence of this species throughout Europe is possibly due to humans. Among sculpins, Cottus scaturigo and C. ferrugineus are junior synonyms of C. gobio. The International Union for Conservation of Nature (IUCN) categories for native species of Italy are updated. At present, 52 native freshwater fish species are listed: 2 are extinct (Acipenser sturio and Huso huso), 12 are critically endangered, 7 endangered, 10 vulnerable, 3 near‐threatened, 15 low concern and 3 data‐deficient; 35 species are the result of human transfers. Among the 51 introduced species, 6 are recently established (Leuciscus leuciscus, Oreochromis niloticus, Poecilia reticulata, Xiphophorus helleri, Amatitlania nigrofasciatus, Hemichromis sp.), 37 are already established, 5 are probably established and 3 are non‐established Chinese carp, maintained in the wild by intensive stockings. The family most involved is the Cyprinidae, with 22 alien and 20 native species.     

Osmoderma eremita as an indicator of species richness of beetles in tree hollows

The beetle Osmoderma eremita has received much attention in the last few years, as it is among those species with the highest priority in the European Union's Habitat Directive. In this paper the species is evaluated as a potential indicator and umbrella species for the endangered beetle fauna in tree hollows. To be useful as an indicator of a species-rich fauna it should be easy to inventory and be strongly correlated with the presence of other species. An umbrella species is a species which is so demanding that the protection of this species will automatically save many others. The species richness of saproxylic beetles and occupancy of O. eremita were surveyed in tree hollows in an area in southeastern Sweden by assessing the presence/absence of living and dead adults (including fragments) and larvae. The species richness was higher when O. eremita was present, both at tree and stand level. Several threatened species were associated with the presence of O. eremita, whereas others did not correlate with the occurrence of O. eremita. As O. eremita is easy to find and identify, it is useful as an indicator of stands with a rich beetle fauna in tree hollows. Osmoderma eremita can be used as an umbrella species, because if measures are taken to conserve O. eremita, many other species in the same habitat are also conserved. However, there are some beetles in tree hollows which seem to be more sensitive to habitat fragmentation than O. eremita, and may go extinct if only O. eremita is taken into consideration.     

Description of a new Nipergasilus species (Family: Ergasilidae) from the gills of grey mullet

A new Nipergasilus species is described from the gills of the grey mullet Valamugil cunnesius from several localities in India and Pakistan. The new species is closely related to Nipergasilus bora (Yamaguti, 1939) which is also recorded here on three species of grey mullet. The genus Nipergasilus is redefined in order to accommodate the second species.

Three new species of <Emphasis Type="Italic">Anthocephalum</Emphasis> Linton, 1890 (Cestoda: Tetraphyllidea) from dasyatid stingrays of the Gulf of California

Three new species of Anthocephalum Linton, 1890 are described from dasyatid stingrays collected in the Gulf of California. Anthocephalum michaeli n. sp. is described from Dasyatis longus (Garman). This species most closely resembles A. alicae Ruhnke, 1994, but differs from this species in proglottid number. A. lukei n. sp. is also described from D. longus. This new species is most similar to A. cairae Ruhnke, 1994, but differs from that species in marginal loculi number and number of proglottids. The third new species, A. currani n. sp., is described from D. brevis (Garman). This species is most similar to A. centrurum (Southwell, 1925) Ruhnke, 1994, but differs from that species in marginal loculi number, number of testes and ovarian length. Phyllobothrium kingae Schmidt, 1978 is also consistent in morphology with species of Anthocephalum and is transferred to this genus, forming the new combination Anthocephalum kingae n. comb. This species most closely resembles A. michaeli n. sp., but differs in testicular shape. This brings the total number of species of Anthocephalum to nine. The transfer of the species Phyllobothrium arctowskii Wojciechowska, 1991, P. georgiense Wojciechowska, 1991, P. rakusai Wojciechowska, 1991 and P. siedleckii Wojciechowska, 1991 to Anthocephalum is not warranted, as these four species lack a posteriorly recurved cirrus-sac and a sinuous vagina, and have vitelline follicles uninterrupted by the ovary. Of the nine known species, all are parasitic in batoid fishes, and six are found in species of Dasyatis Garman. The phylogenetic status of Anthocephalum species in relationship to Rhinebothroides Mayes, Brooks & Thorson, 1981, Pararhineothroides Zamparo, Brooks & Barriga, 1999 and other rhinebothriin taxa is discussed.     

Molecular phylogenetic analysis of New Zealand mosquito species

ABSTRACT

Taxonomic information for New Zealand mosquito species is predominantly morphological with very few molecular data available to date. In this study, the mitochondrial COI gene and nuclear ITS1 were amplified and sequenced from DNA templates representing 17 species; 15 previously known New Zealand species, a newly discovered undescribed Aedes species from the Chatham Islands and a recently eradicated invader, Ae. camptorhynchus. This paper provides DNA barcoding sequences for the entire known New Zealand mosquito fauna, the first for the majority of these species. Phylogenetic analysis of COI and ITS1 indicated that the endemic species are all genetically distinct from the exotic species examined including vector species of pathogens of human diseases. The genus Opifex is distant from the genus Aedes based on analysis of ITS1 sequences, and Ae. chathamicus is more closely related to species within Aedes than to the genus Opifex. Results show Culex asteliae to be a valid species but Cx. rotoruae is not necessarily so. The Aedes species appears to be closely related to Ae. subalbirostris. The introduced Cx. quinquefasciatus was clearly shown to be related to Cx. pipiens; however, the endemic Cx. pervigilans was not. No evidence of population variation based on geographic location was detected.     

Ectomycorrhizal fungal communities of native and non-native Pinus and Quercus species in a common garden of 35-year-old trees

Non-native tree species have been widely planted or have become naturalized in most forested landscapes. It is not clear if native trees species collectively differ in ectomycorrhizal fungal (EMF) diversity and communities from that of non-native tree species. Alternatively, EMF species community similarity may be more determined by host plant phylogeny than by whether the plant is native or non-native. We examined these unknowns by comparing two genera, native and non-native Quercus robur and Quercus rubra and native and non-native Pinus sylvestris and Pinus nigra in a 35-year-old common garden in Poland. Using molecular and morphological approaches, we identified EMF species from ectomycorrhizal root tips and sporocarps collected in the monoculture tree plots. A total of 69 EMF species were found, with 38 species collected only as sporocarps, 18 only as ectomycorrhizas, and 13 both as ectomycorrhizas and sporocarps. The EMF species observed were all native and commonly associated with a Holarctic range in distribution. We found that native Q. robur had ca. 120% higher total EMF species richness than the non-native Q. rubra, while native P. sylvestris had ca. 25% lower total EMF species richness than non-native P. nigra. Thus, across genera, there was no evidence that native species have higher EMF species diversity than exotic species. In addition, we found a higher similarity in EMF communities between the two Pinus species than between the two Quercus species. These results support the naturalization of non-native trees by means of mutualistic associations with cosmopolitan and novel fungi.     

Monophyletic origin of Caryophyllia (Scleractinia,Caryophylliidae), with descriptions of six new species

The genus Caryophyllia Lamarck, 1816 is the most diverse genus within the azooxanthellate Scleractinia comprising 66 Recent species and a purported 195 nominal fossil species. Examination of part of the deep-sea scleractinian collection made by the Paris Museum off New Caledonia and part of the material collected by CSIRO off Australian waters revealed the occurrence of 23 species of Caryophyllia, of which six are new to science. All new records, including the new species, are described, and synonyms, distribution, type locality, type material and illustration are provided for each species. An identification key to all Recent species of Caryophyllia is presented. In addition, the validity of the genus Caryophyllia was investigated by phylogenetic analyses of a dataset consisting of partial mitochondrial 16S rRNA sequences from 12 species assigned to this genus together with seven species representing some of the most morphologically similar caryophylliid genera, and 14 non-caryophyllid species representing 14 scleractinian families. Irrespective of the method of analysis employed, all of the Caryophyllia species formed a well-supported clade together with Dasmosmilia lymani and Crispatotrochus rugosus. Although based on a subset of the Recent Caryophyllia species, these results are consistent with Caryophyllia being a valid genus, but call for a reexamination of Dasmosmilia and Crispatotrochus.     

Descriptions of two new and one little known species of the genus Cacopsylla (Hemiptera: Psyllidae) on Sorbus japonica (Rosaceae) and an observation of their biology

Three species of the genus Cacopsylla were collected from Sorbus japonica in Japan. Two of them, Cacopsylla elegans and Cacopsylla sorbicoccinea, are described as new species based on adults and fifth (final) nymphal instars. The third species, Cacopsylla midoriae, is newly transferred from the genus Psylla. The adult of C. midoriae is redescribed and the nymph is described for the first time. A key to the species feeding on S. japonica (adults and nymphs) is provided. The three species were observed to coexist on the same tree of S. japonica in northern Kyushu. Such coexistence of psylloid congeners is uncommon in Japan.     

Taxonomy and phylogeny of Puccinia lagenophorae: a study using rDNA sequence data, morphological and host range features

Puccinia lagenophorae is a rust fungus originating from Australasia which has spread throughout the world. A phylogenetic analysis of taxa related to this species was performed using rDNA (LSU, ITS) sequence data. The analyses revealed a well-supported cluster including all specimens of P. lagenophorae. By evaluating morphological and sequence data, the species is taxonomically re-defined and a list of synonyms is provided. Puccinia distincta on Bellis perennis, a species recently separated from P. lagenophorae, P. saccardoi, a species on the Goodeniaceae, and P. byliana, a species so far only known from South Africa, are reduced to synonymy in P. lagenophorae, as are several other species. Our analysis indicates that P. lagenophorae is likely not derived from the northern hemisphere species P. obscura, but from a species from Australia host-alternating between Asteraceae (aecial host) and Cyperaceae/Juncaceae (telial host). Another related species, P. stylidii (on Stylidium sp., Stylidiaceae) may have been derived from the same parental species as P. lagenophorae. From ontogenetical and morphological studies, the presence of pycnia could not be confirmed in the life cycle of this species, and the width of the pedicel of teliospores at the point of attachment was found to be highly variable and not a taxonomic character. The number of known host species is approximately 150, including 41 new host plants recorded herein.

A review of the West Palaearctic aphidiines (Hymenoptera: Braconidae: Aphidiinae) parasitic on Uroleucon spp., with the description of a new species

A review of aphidiine wasps (Hymenoptera: Braconidae) parasitizing the Uroleucon species in the West Palaearctic is presented. Eleven species are keyed and illustrated. In addition, a new hymenopteran parasitoid species: Praon nonveilleri n. sp. from Uroleucon inulicola (Hille Ris Lambers) infesting Inula ensifolia L., is described. The new species is diagnosed and illustrated. It belongs to the “dorsale-yomenaé” species group and was collected from the Djetinja canyon in Serbia and Montenegro. The aphidiines presented in this work were identified from 97 aphid taxons occurring on 236 plant taxons. Furthermore, 361 original parasitoid – host aphid – host plant associations of the species mentioned in the key are presented. Finally, phylogenetic relationships inside the “dorsale-yomenae” species group and related species were reconstructed using cladistic distance methods.     

A new species of Acanthobothrium van Beneden, 1850 (Tetraphyllidea: Onchobothriidae) from Pastinachus atrus (Macleay) (Batoidea: Dasyatidae) in Australian waters, with a reassessment of the host associations of Acanthobothrium spp. parasitising Pastinachus spp

A new Category 1 species of Acanthobothrium van Beneden, 1850 is described from the cowtail stingray Pastinachus atrus (Macleay) collected from the Gulf of Carpentaria near Weipa, Queensland, Australia. This species is unique among Acanthobothrium Category 1 species in that it retains gravid proglottids on its strobila. It differs further from the 34 other Category 1 species in total length, proglottid number and testis number. The host identities of other Acanthobothrium species reported from Pastinachus are revised based on recent taxonomic work on rays of this genus. Given the revised host taxonomy, according to which P. atrus is the only member of its genus occurring off Australia, this should be considered to be the fifth species of Acanthobothrium reported from this Australian endemic species.
