In this paper we describe fossil conifer branches discovered in the Mesaverde Group, Williams Fork Formation in northeastern Utah, along Snake John Reef. Fossil conifers from the Campanian of northeastern Utah have not been previously studied, despite their common occurrence in the formation. The recovered fossils closely resemble Geinitzia known from the late Cretaceous of Europe, with several previous reported occurrences in North America, including New Jersey and Southern Utah. The fossils share morphological characteristics with Geinitzia, exhibiting short spirally arranged thin needles, with appressed scale-like leaves along the shoots. They differ from Araucarites in that the appressed needles are more scale like and smaller, and differ from the members of the modern Araucariaceae in lacking broad bases to the needles, although the fossils resemble the modern species Araucaria heterophylla (Norfolk Island Pine) native to the South Pacific. The observed branching pattern in the fossil reflects similarities found in the Cupressaceae Family, and Geinitzia may be regarded as an early member of this group, or having an affinity to fossil Araucariaceae conifers, which despite having a modern southern hemisphere geographic distribution today were widespread during the late Mesozoic, extending across North America and Europe.

Trechodes laophilus Deuve, 2002 is firstly recorded from Thailand (Chiang Mai province, Mae lai river). This species is probably closely related to T. leclerci Deuve, 1987 and T. satoi Uéno, 1991, both from Thailand too. An identification key including the morphology of the aedeagus, to all Trechodes species recorded from the Oriental region, as well as a distribution map of the species known so far from Thailand, are provided.Moreover, the following new synonymy is proposed: Blennidus magellanicus Allegro & Giachino, 2017 = Trirammatus unistriatus nocticolor Straneo, 1955 syn. n.

Chloride Concentrations

As part of an investigation into the deterioration of Norfolk Island pine, Araucaria heterophylla (Salisb.) Franco, on the coast of eastern Australia, seedlings were grown in nutrient solutions in which sodium was substituted for potassium over the range 0.1 - 2.1 mM to give six treatments, each with four ratios of sulfate to chloride. Potassium was freely taken up and translocated to the shoots, the levels in the shoots being higher than those in the roots. However, the levels of potassium in both shoots and roots were significantly reduced in solutions in which sulfate predominated over chloride. Uptake and translocation of sodium was restricted, the ratio of sodium (shoots) to sodium (roots) being less than unity. The concentration of chloride in the shoots and roots generally increased with increasing solution chloride concentration but was significantly reduced at the lowest potassium-to-sodium ratio. In a second experiment the ratio of sodium to potassium was kept at 50:1, sodium and chloride in the solutions increasing from 2.5 to 460 mM and potassium from 0.05 to 9.2 mM. At the lower concentrations, uptake and translocation followed similar patterns to those found in the first experiment. However at solution concentrations of 20 mM sodium and above, levels of sodium in the shoots exceeded those of potassium and chloride. At sodium chloride concentrations of 260mM - 460mM, plants showed toxic symptoms with salt encrustations appearing on the stems. Analysis of the saturation extracts of soils taken from beneath affected seaside trees showed that the concentrations of sodium and chloride were not sufficiently high to account for the high levels of these elements found in the shoots of affected trees.

Necropsy on 15 specimens of white-tufted grebe, Rollandiarolland, caught in the Mar Chiquita and Chascomús lagoons (Buenos Aires province), revealed the presence of Contracaecumovale (Linstow, 1907). This nematode shows a marked specificity for podicipediform birds. The specimens were identified from morphological study on features such as cephalic and esophageal structures and caudal papillae, using both optical and scanning electron microscopy. This is the first record of C. ovale parasitizing R. rolland in Argentina.

The taxonomy of the leafhopper genus Makilingia Baker is reviewed based on comparative morphological study of types and other specimens. Twenty-six species are recognized as valid including ten new species described and illustrated herein: M. davaoensis n. sp. M. lobata n. sp., M. maculamima n. sp., M. nigramima n. sp., M. paranigra n. sp., M. siamensis n. sp., M. tenebrifrons n. sp., M. uncinata n. sp., M. viraktamathi n. sp., and M. xanthopicta n. sp. Makilingia siamensis n. sp. represents the first known occurrence of the genus outside the Philippine Archipelago and the first record for Thailand. Makilingia simillima Baker, n. stat., formerly treated as a variety of M. variabilis Baker, is elevated to full species status based on distinctive differences in the male genitalia. Lectotypes are designated for several species described by Baker. The male genitalia of these species are described and illustrated for the first time and a key to all known species is provided.

Abstract Sphincterodiplostomum is a monotypic genus of diplostomid digeneans that parasitize fish-eating birds in the neotropics. The type species Sphincterodiplostomum musculosum has a unique, dorsal, tubular invagination in the opisthosoma with a muscular sphincter. Whereas larvae of S. musculosum are relatively commonly reported in Neotropical fish helminth surveys, adult specimens from birds are rarely collected. Prior to our study, no DNA sequence data for S. musculosum were available. Our molecular and morphological study of mature and immature adult Sphincterodiplostomum specimens from three species of birds and one species of crocodilian revealed the presence of at least two species of Sphincterodiplostomum in the neotropics. We provide the first molecular phylogeny of the Diplostomoidea that includes Sphincterodiplostomum. In addition, this is the first record of S. musculosum from caimans, along with the first record of fully mature adult S. musculosum from green kingfisher Chloroceryle americana. The new species of Sphincterodiplostomum (Sphincterodiplostomum joaopinhoi n. sp.) can be morphologically distinguished from S. musculosum based on the anterior extent of vitelline follicles, narrower prosoma, substantially smaller holdfast organ and structure of tegumental spines. Our data revealed 0.7% interspecific divergence in 28S and 10.6–11.7% divergence in cox1 sequences between the two Sphincterodiplostomum species.

Shoot Necrosis

A disorder of Norfolk Island pines, Araucaria heterophylla (Salisb.) Franco, has occurred on certain urbanized parts of the coast of New South Wales. Observation and survey work suggested that the disorder was due to excessive foliar uptake of salt, induced by surfactants derived from sewage discharged into the sea. The work described in this paper was part of a programme of studies designed to test this hypothesis. Glasshouse experiments were carried out to test the effects of distilled water and deep-sea water both with and without added surfactants sprayed onto the foliage of young potted Norfolk Island pines. Whereas the distilled water effects were minimal, some needle and shoot necrosis occurred in all plants sprayed with sea water and this effect was markedly accentuated when surfactant was present. Shoot necrosis was highly significantly correlated with the concentration of sodium and chloride taken up by the foliage, and the foliar salt levels were very similar to those found in deteriorating trees located by the seaside. The results showed that a commonly used surfactant, when sprayed in a sea-water solution onto Norfolk Island pine foliage, caused damage similar to that observed in affected seaside trees.
