Successful Establishment

AbstractTwo new species of Psoroma with unusual cephalodia are described: P. echinaceum with isidiate cephalodia, from southern South America and P. geminatum with fragile phyllidiate cephalodia, from New Zealand and Australia. These are additional to two previously described species producing dispersal units on their cephalodia, P. durietzii P.James & Henssen (with soredia) and P. aphthosum, Vain. (syn. nov. P. dimorphum Malme) (with isidia). This is a strategy development that ensures successful establishment of new thalli.

A New Species

Metanteon poirieri sp. nov. (Hymenoptera: Dryinidae: Anteoninae) is described from New Caledonia. The genus Metanteon Olmi, 1984, was known only from the southern region of Argentina and Chile. The unique species attributed previously to this genus is M. aerias (Walker, 1839), collected in Chile by Charles Darwin during his famous trip on the HMS Beagle. M. aerias is associated only with leafhoppers feeding on Southern Beeches (Nothofagus spp.), a genus of Nothofagaceae including species of trees and shrubs native to the southern Hemisphere in southern South America (Argentina, Chile) and Australasia (east and southeast Australia, New Zealand, New Guinea and New Caledonia). Like Nothofagus, Metanteon is a transantarctic organism.

First Time

The diverse bee genus Psaenythia Gerstaecker (Panurginae, Protandrenini), hitherto known from central and southern South America, is recorded from northern South America for the first time. Two new species are described: Psaenythia diceratops, sp. n., from northeastern Colombia, and P. guaricoensis, sp. n., from central Venezuela. The males of P. diceratops are noteworthy for possessing prominent apicolateral clypeal horns, elongate scythe-like mandibles, and displaying macrocephaly with strong dimorphism.

Morphological Differences

The tabanid tribe Diachlorini (Diptera) is the most genus-rich tribe in the Tabanidae; the tribe is cosmopolitan, but the greatest species richness and morphological diversity are found in the Australasian and Neotropical Regions. A new arrangement for the species of Acellomyia González is given; Acellomyia lauta (Hine) is transferred to a new genus, Montismyia gen.n., based on its morphological differences from Acellomyia and geographical distribution. The morphological differences between Acellomyia and Montismyia gen. n. are discussed. Two new species, Acellomyia casablanca sp.n. and Acellomyia puyehue sp.n., are described from specimens collected in southern Chile. Comparison of the morphology of Acellomyia paulseni mapuche (Coscarón & Philip) stat.nov. indicate that they should be elevated to species rank. A key to species of Acellomyia is provided and diagnostic characters are illustrated.

Abstract A. areolatum is a basidiomycete that causes a white rot of a broad range of conifers. Its invasiveness arises from a symbiotic association with woodwasps of the genus Sirex. The species Sirexnoctilio is listed as "highly invasive" on the ISSG/IUCN website (ISSG, 2008) and is a Regulated Pest for the USA (APHIS, 2009a). The wasp and the fungus are native to Europe, North Africa and western Asia where their damage is considered secondary (Spradbery and Kirk, 1978). Introduced to areas of the Southern Hemisphere where exotic pine species are grown in plantations, these organisms have caused major losses. The insect invaded New Zealand by at least 1900, but did not cause serious concern until the 1940s (Talbot, 1977). It later spread to Tasmania and the southern parts of Australia and the wasp/fungus association was introduced into southern South America, beginning in Uruguay in 1980 (Ciesla, 2003). Invasion of South Africa occurred in 1994 (Tribe, 1995). Woodwasps are repeatedly detected in material imported to the USA, but were successfully excluded until 2004 (Wilson et al., 2009). The wasp and fungus were later found in nearby Canada (Ontario), although apparently due to a separate introduction (Bergeron et al., 2008; Wilson et al., 2009). Recent surveys found the wasp in four states of the USA (Evans-Goldner and Bunce, 2009) and 25 counties of Ontario in Canada (Shields, 2009). Schiff (2008) summarizes differences in complexity of the ecological situations in the Southern Hemisphere countries and North America that could affect spread and impact of the fungus and wasp.

Ever since J. D. Hooker's famous 'Introductory Essay' to Flora NOVE-Zelandise, a classical problem in biogeography has been to give a casual explanation of southern hemisphere distribution patterns. An attempt is made to see whether the cladograms for the circum-Pacific areas (South America, New Zealand, Tasmania and Australia) are congruent. The area cladograms are derived from Nothofagus (Fagacae), Embothriinae (Protaceae), Oreobolus (Cyperaceae), Cyttaria (Helotiales) and Eriococcidae (Homoptera). The resulting general area cladogram showing southern South America as the sister-area to New Zealand, south-eastern Australia and Tasmania, and Tasmania plus south-eastern Australia as sister-areas to New Zealand are compared with different geological hypotheses for the area. The biological area cladogram is shown to be congruent with widely different geological hypotheses.

The new subfamily Struthiopterinae is proposed for the aporrhaid gastropods occurring in the Late Cretaceous-early Tertiary Weddellian Province along the southern margin of the Pacific. The following genera are placed within the Struthiopterinae: Struthioptera Finlay and Marwick, 1937; Austroaporrhais n. gen.; and Struthiochenopus n. gen. The temporal and biogeographic distribution of members of Struthiopterinae show a similar pattern to other Southern Hemisphere groups of Late Cretaceous and early Cenozoic molluscs with initial disappearance from the western Australasia of the Weddellian Province by the Paleocene while surviving in Antarctica until the late Eocene and eventually disappearing in southern South America during the early Miocene.Also included in this paper is a reappraisal of the species assignable to these genera from Late Cretaceous and early Tertiary of New Zealand, Antarctica, and southern South America together with the description of five new species. The following new species of the Struthiopterinae are described: Austroaporrhais larseni n. sp., A. stilwelli n. sp., A. dorotensis n. sp., Struthiochenopus antarcticus n. sp., and S. philippii n. sp.

The discovery of two diminutive and very distinct ibliform barnacles from shallow waters off northern New Zealand and northeastern Tasmania provides an opportunity to re-evaluate the Iblidae, the most primitive of the living thoracicans. These are retained within the Superorder Thoracica, but are distinguished at ordinal level from the remainder of the Pedunculata s.l. The resultant new order, the Ibliformes nov., comprises barnacles with predominantly chitinous rather than calcareous capitular plates; two families are recognized, the Iblidae s.s., comprising two subfamilies, the Iblinae (Ibla s.s.) and the Neoiblinae nov. (Neoibla gen. nov.), and the Idioiblidae nov. comprising the Idioiblinae nov. (Idioibla gen. nov.) and the Chaetolepadinae nov. (Chaetolepas Studer, 1889 and Chitinolepas gen. nov.). The monotypic Chitinolepas further highlights the high endemism and relict nature of the New Zealand marine fauna in particular and the southern hemisphere in general. On the basis of morphology and, where possible, genetic and larval work, it is recommended that the remainder of the stalked thoracicans be divided between three new orders, the †Cyprilepadiformes, Ibliformes, Lepadiformes and Scalpelliformes.
