Phytoplasma Vector

We report results from a survey of palm-associated Fulgoroidea (planthoppers), following the recent discoveries of Haplaxius crudus, a known palm phytoplasma vector, and of other potential planthopper vectors in Puerto Rico. The survey, which sampled from 40 sites, resulted In the identification of 30 morpho-species belonging to eight Fulgoroidea families. The 10 most common species accounted for 93.9% of individuals, whereas near one third (n = 9) of the species were represented by single individuals. Derbids and cixiids accounted for 90% of collected individuals. The most common species were the derbids Cedusa inflata (Ball) and Omolicna puertana Caldwell, while the most common cixiids were Bothriocera undata (F.) and Oliarus complectus Ball; and the most common flatids were Petrusa epilepsis (Kirkaldy) and Melornemis antillarum (Kirkaldy). Three species are new records for Puerto Rico: the cixiids Haplaxius crudus Van Duzee and Nymphomyndus caribbaea (Fennah), and the derbid Neocenchrea ca. pallida Metcalf. Impact of polyphagy and of abundance-diversity patterns of this planthopper guild on phytoplasma epidemiology are briefly discussed.

High Diversity

AbstractA survey of driftwood and mangrove wood in South Australia revealed a high diversity of marine fungi. Across eight sites there were 43 species of marine fungi, of which 42 are new records for South Australia, 11 new records for Australia and 12 taxa currently of uncertain status likely to be new species. Sites had distinctive species compositions with the largest difference attributable to substrate type (beach driftwood vs. mangrove wood). However, even between mangrove sites, species assemblages were distinctly different with only the more common species occurring at all mangrove sites. More intensive surveys across a broader range of habitats and geographic locations should reveal significantly more species.

Superfamilies Aradoidea, Pyrrhocoroidea and Coreoidea from Puerto Rico are discussed as part of an updated account of Hemiptera: Heteroptera. In this final part, we present 48 species belonging to the three superfamilies, with six families known from Puerto Rico: Aradoidea: Aradidae (12); Pyrrhocoroidea: Largidae (1) and Pyrrhocoridae (3); and Coreoidea: Alydidae (5), Rhopalidae (7) and Coreidae (20). Taxonomic accounts presented here include synonymies, known distribution, lists of host plants and a listing of examined specimens. Taxonomical keys are also provided for the identification of all taxa included. Color plates for 43 species are included. Five species are new records for Puerto Rico: Brachyrhynchus membranaceus (F.), Leptoglossus confusus Alayo and Grillo, Eubule scutellata (Westwood), Mamurius cubanus Barber and Bruner, and Merocoris typhaeus (F.). Most species are widespread in the West Indies, with the largest number of island endemics in the Aradidae. A discussion of the origins, biodiversity, biogeography, and endemism of all Puerto Rican Pentatomomorpha is presented.

The green peach aphid, Myzus persicae Sulzer, is a pest of tobacco in Puerto Rico. This insect is also a vector of virus diseases transmitted from pepper to tobacco and vice-versa. During a survey made in Puerto Rico by the authors, the known host-plant list of this insect was greatly increased by adding around 15 new records.

Aquatic fungi were isolated from sea foam, leaf litter, beach sand, and driftwood in an estuary known as "La Boca" (river mouth) of the Manatí River in Barceloneta, northern Puerto Rico. Observations of the baits (sterilized balsa wood) and incubated organic debris, revealed the presence of 28 species of aquatic fungi, 13 of which belong to the ascomycetes and 15 to the mitosporic fungi. The species Arenariomyces triseptatus, Corollospora cf. colossa, C. filiformis, Halosphaeria sp., Kirschsteiniothelia sp., Astrosphaeriella aff. mangrovei, Torpedospora radiata (Ascomycota), Brachiosphaera tropicalis, Campylospora sp., and Clavatospora bulbosa (Mitosporic fungi) were the most common in the samples. Eleven species are new records for Puerto Rico; six fungal isolates could not be identified.

First Time

Based largely on collections from the Calanus–Salvelinus expeditions, 54 species of thecate hydroids were identified from the shelf waters of northern Canada between northeastern Newfoundland and the Alaska–Yukon border. Common species included Halecium muricatum, Calycella syringa, Campanularia integra, C. speciosa, C. volubilis, Gonothyraea loveni, Filellum serpens, Lafoea gracillima, Sertularella polyzonias, S. tricuspidata, Sertularia schmidti, and S. similis. Halecium groenlandicum, H. scutum, Cuspidella procumbens, Calycella gracilis, and Sertularia schmidti are new records for North America; Ptychogena lactea is previously known from this continent only as the medusa. Twenty-two species are reported in northern Canada for the first time, bringing to 71 the number of thecate species recorded from the region. Nearly half of the 71 species recorded are circumpolar in distribution, and over two-thirds transgress both arctic and subarctic zones.Most samples had a paucity of hydroids, particularly those from the high arctic. Collection records indicate that the most favourable regions for hydroids in northern Canada are the Strait of Belle Isle, eastern Ungava Bay, eastern Hudson Strait, northern and southeastern Hudson Bay, Foxe Channel, and northern Foxe Basin.

Myxomycetes on the bark of dead Banksia attenuata and B. menziesii from the Perth metropolitan area of Western Australia were surveyed by the moist chamber technique, to determine whether the flora was similar on both hosts and what were the most important variables that determined the distribution of the most common species. Twenty-seven species of myxomycetes were recovered, including six new records for Australia (Comatricha rigidireta, Echinostelium elachiston, Paradiacheopsis cf. cribrata, P. rigida, Stemonitopsis amoena and S. cf. hyperopta). Members of the order Stemonitales comprised the largest number of species, whereas members of the Liceales occurred on the most bark pieces. The most common species were Licea kleistobolus, Echinostelium minutum, Comatricha elegans, Cribraria minutissima and Paradiacheopsis fimbriata. Overall, B. menziesii and B. attenuata had very similar myxomycete productivity, diversity and species assemblage, as did the tops and bottoms of the logs. It was concluded that they provided very similar microhabitats for myxomycetes. Both pH and the relative moisture content of the bark had an effect on myxomycete productivity. Bark decomposition level, pH and bark surface (top or bottom) were the most important variables determining the distribution of the most common myxomycete species.

First Time

The current knowledge of pseudoscorpions in Estonia is summarized, based on specimens preserved in various Estonian collections and new material collected from 1993 to 2015. Altogether 474 studied specimens belonged to 14 species, including nine species recorded from Estonia for the first time. Supplemented by Apocheiridium rossicum, listed by literature data only, the number of known Estonian pseudoscorpions is now set at 15. The findings of Mesochelifer ressli are the northernmost known for the species. Some ecological and phenological observations were made on the most common species, along with notes on the habitat preferences of other species and the use of different trapping methods. The composition of the known Estonian fauna is compared with the published records from the neighbouring countries, revealing a highest similarity to the Finnish fauna.The possible occurrence of other species in Estonia and the latitudinal species diversity gradient in the Eastern Baltic region are shortly discussed.

A search was conducted in Puerto Rico for nodulated indigenous tropical legumes which show possible potential for agricultural purposes. Forty nine such legume species were encountered, of which 13 were new records for nodulation. Descriptions are given for the rhizobial nodules on the 49 species and agronomic observations on the growth habits of the plants and their habitats are furnished.
