Keys and diagnoses of North European aphids (Hemiptera, Aphidoidea) associated with mosses, horsetails and ferns are given, based on fresh and freeze-dried material. Numerous externally visible and thus informative characters, that are absent in cleared, slide-mounted specimens, such as body shape colours, wax coating and pattern etc., are utilized. Most of the species are illustrated by photographs of live specimens and drawings. Root-feeding species living in the moss layer or otherwise often present in moss samples are also included, even if their hosts were spermatophytes. The combination of colour images and diagnoses, utilizing easily observed characters, allows the identification of a large number of species already in the field, and many more at home with the aid of a stereo microscope. Host plant relationships and association with ants are summarised, including new records. Brief accounts on aphid life cycles, freeze-drying preparation techniques, etc. are also given to support the use of the keys.
This paper updates the knowledge about the occurrence of armored scale insects on tropical fruit trees in Argentina, and Pseudaulacaspis cockerelli (Cooley) is recorded for the fi rst time from Argentina and South America. Herein we present three new associations for the world: Aonidiella aurantii (Maskell) / Musa paradisiaca L.; Hemiberlesia cyanophylli (Signoret) / M. paradisiaca, and Acutaspis paulista (Hempel) / Persea americana Miller, and 10 new associations of armored scale / tropical fruit for Argentina are presented. Acutaspis paulista, Hemiberlesia palmae (Cockerell), Mycetaspis personata (Comstock) and P. cockerelli are cited for the first time on tropical fruits in this country.
Morphological (shell) and molecular examination of a large suite of specimens of pleurotomariids from around New Caledonia and the Coral Sea reveals the existence of four species in the complex of Perotrochus caledonicus: Perotrochus deforgesi Métivier, 1990 and P. pseudogranulosus sp. nov. live allopatrically on the plateaus and guyots of the Coral Sea; Perotrochus caledonicus Bouchet & Métivier, 1982 and Perotrochus wareni sp. nov. live sympatrically - but essentially not syntopically - on the slopes of New Caledonia, Norfolk Ridge and the Loyalty Ridge. All species live in the 300–500 m interval, and together form a significant component of the mollusc fauna living on hard bottoms in the SW Pacific, with individual dredge hauls containing up to 25 specimens of Perotrochus.
Identification of caddisfly specimens (Insecta: Trichoptera) from Vietnam collected by or for the Royal Ontario Museum, the American Museum of Natural History, and the Museum für Naturkunde der Humboldt-Universität zu Berlin revealed nine new species in a variety of families and genera. New species include:
Philopotamidae—Dolophilodes carpenteri and Wormaldia montuosa; Stenopsychidae—Stenopsyche siniaevi; Polycentropodidae—Nyctiophylax hatinh; Psychomyiidae Eoneureclipsis afonini; Hydropsychidae—Maesaipsyche lappa; Glossosomatidae—Agapetus darlingi and Agapetus grimaldi; and, Molannidae—Molannodes sapa. In addition, new records for 11 species and two genera (Georgium and Tagalopsyche) of caddisflies from Vietnam are herein noted.
Sharon gen. nov. is here described to include Asaphes? amoenus Philippi, 1861 comb. nov. from Chile. A redescription of the species is based on the female holotype and material from different geographic locations. Candèze (1891) placed Asaphes amoenus and Parasaphes elegans in the suprageneric group Asaphites. We discuss differences between Sharon gen. nov. and Hemicrepidius Germar, 1839, where Asaphes amoenus was later placed by Blackwelder (1944). Based on morphological characters, Sharon gen. nov. appears to be related to Parasaphes Candèze, 1881, Wynarka Calder, 1986, and Tasmanelater Calder, 1996, all from Australia, suggesting Gondwanan relationships.
The fauna of Panama is species-rich due to its location and topography, and the resulting diversity of microclimates and habitats. The last summary of information about the caddisfly fauna (Insecta: Trichoptera) of Panama in 1992 noted 168 taxa in 13 families and 39 genera. Since then, and through 2014,
a large number of publications, based on work by a dedicated cadre of individuals, have recorded a net gain of 78 species and six genera. In 2015, 17 new species to science and 38 new country records were added, including one new family and two new genera for the country; and, two species were removed. Thus, 299 species of caddisflies are now known from the Republic of Panama and are distributed among 14 families
and 47 genera. Given the higher diversity in neighboring Costa Rica (>500 species), we feel certain that there are many more species yet to be discovered.
The Republic of Panama currently has 245 recorded species of Trichoptera distributed among 13 families. Herein we add 32 new country records for Panama, including one new family (Limnephilidae) and one new genus (Limnephilus). We also provide the first collection information for Oxyethira maya Denning for Panama. These results are part of an ongoing effort to characterize the caddisfly fauna of Panama, and to evaluate that country’s major cuencas (water basins).
Two new junior synonyms, Pseudomesitius Duchaussoy, 1916 syn. nov. and Triglenus Marshall, 1905 syn. nov., for the genus Bradepyris Kieffer, 1905 are proposed and a new diagnosis for the genus is given. Two new species (based on males) from the Saharo-Arabian region are here described: Bradepyris jordanicus, sp. nov. and B. baleariensis, sp. nov. A brief revision, with a key to the males and females of all species of this genus, and the first male genitalia descriptions are also provided.
A new sepioline species, Sepiola boletzkyi sp. nov. (Cephalopoda: Sepiolidae), is described based on two specimens from the Aegean Sea (eastern Mediterranean). The type specimens are lodged in the Ege University Faculty of Fisheries Museum of Izmir (Turkey). The new species belongs to the Sepiola atlantica group sensu Naef, hence it is compared with the species in this group, namely Sepiola affinis, Sepiola atlantica, Sepiola bursadhaesa, Sepiola intermedia, Sepiola robusta, Sepiola rondeletii, Sepiola steenstrupiana and Sepiola tridens. The male of S. boletzkyi sp. nov. differs from all the others in having the combination of homomorphous ventral arm tips, eight enlarged suckers, subdivided into two groups, in the dorsal row of the distal part of the hectocotylus and a dorsal lobe complementing the copulatory apparatus. In females of S. boletzkyi sp. nov. the bursa copulatrix is large and, unlike all other species in the genus, has a large fungiform process towards the mantle wall. The discovery of S. boletzkyi sp. nov. increases to 12 the number of NE Atlantic- Mediterranean species of Sepiola.
A new species of Paracrobeles, P. kelsodunensis sp. nov. is described from the Kelso Dunes area, Mojave National Preserve, southern California. Paracrobeles kelsodunensis sp. nov. is particularly characterised by a body length of 469–626 μm in females and 463–569 μm in males; lateral field with four incisures, extending almost to tail terminus; three pairs of asymmetrical lips, separated by U-shaped primary axils with two long guarding processes, each lip usually with four tines along its margin; three long labial probolae, deeply bifurcated, with slender prongs without tines; metastegostom with a strong anteriorly directed dorsal tooth; pharyngeal corpus anteriorly spindle-shaped, posteriorly elongate bulbous with dilated lumen; spermatheca 24–87 μm long; postvulval uterine sac 60–133 μm long; vulva in a sunken area; spicules 33–38 μm long; and male tail with a 5–8 μm long mucro. The generic diagnosis is emended on the basis of recently described species and a key to the species of Paracrobeles is provided.
