In a collection of terrestrial isopods from Venezuela, a distinct species was identified which does not fit any of the known genera. Therefore, a new taxon Metaprosekia gen.n. is instituted to accomodate the new species. An analysis of its morphological characters revealed a close relationship to the genus Prosekia Vandel, 1968 and allied genera. The phylogeny of this group is discussed and one of its poorly known representatives, Xiphoniscus mirabilis Vandel, 1968 is redescribed on the basis of the type material.

AbstractElectroborus brighti, new genus, new species (Coleoptera: Curculionidae: Scolytinae) is described based on two specimens from Dominican amber, which represents the first Hylesinini found in Dominican amber. A phylogenetic analysis of 24 Hylesinini species and a Strombophorus Hagedorn species based on morphological characters suggests E. brighti is not related to the Neotropical genus Phloeoborus Erichson, but shares a close affinity to African Hylesinini genera. The discovery of this new genus adds to the evidence that tropical South America and Africa shared similar faunas throughout evolutionary history. Although many Old World taxa have become extinct in the New World, the existence of E. brighti among Recent faunas is a possibility, given that the South American and African scolytine faunas are relatively poorly studied.

A new genus of Sycophaginae (Hymenoptera: Agaonidae), Sycidiphaga Liu, Rasplus & Huang n. gen., is described with a single new species, S. cyrtophyllae Liu, Rasplus & Huang n. sp. This species was discovered in Yun Nan and Gui Zhou, China and is associated with Ficus cyrtophylla (Moraceae, Ficus, subgenus Sycidium). The new taxon is readily distinguished from other genera of Sycophaginae by: 1) the presence of a conspicuous interantennal blade-like projection that extends well above the level of the toruli; 2) an inflated parastigma surrounded by a slight infuscation of the wing membrane; 3) the presence of a long and conspicuous median sulcus on the male pronotum; and 4) the presence of dense and long pilosity on the wings. Illustrations and a diagnosis and description of Sycidiphaga are provided, as is a key to the world genera of Sycophaginae. The phylogenetic position of Sycidiphaga was demonstrated through sequencing four gene regions of COI, Cyt b, 28s D3-D5 and EF-1α genes and conducting a phylogenetic analysis of available sequences for the subfamily. Sycidiphaga cannot be placed with confidence within Sycophaginae but several discussed characters suggest a close relationship with Idarnes Walker and Sycophaga Westwood.

The generic taxonomy of the Nothofagaceae is revised. We present a new phylogenetic analysis of morphological characters and map these characters onto a recently published phylogenetic tree obtained from DNA sequence data. Results of these and previous analyses strongly support the monophyly of four clades of Nothofagaceae that are currently treated as subgenera of Nothofagus. The four clades of Nothofagaceae are robust and well-supported, with deep stem divergences, have evolutionary equivalence with other genera of Fagales, and can be circumscribed with morphological characters. We argue that these morphological and molecular differences are sufficient for the four clades of Nothofagaceae to be recognised at the primary rank of genus, and that this classification will be more informative and efficient than the currently circumscribed Nothofagus with four subgenera.        Nothofagus is recircumscribed to include five species from southern South America, Lophozonia and Trisyngyne are reinstated, and the new genus Fuscospora is described. Fuscospora and Lophozonia, with six and seven species respectively, occur in New Zealand, southern South America and Australia. Trisyngyne comprises 25 species from New Caledonia, Papua New Guinea and Indonesia. New combinations are provided where necessary in each of these genera.

A new species, Scrophularia jinii (Scrophulariaceae), from Central China is described and illustrated. This new species was formerly misidentified as S. fargesii, from which it differs in many morphological characters. Moreover, it is distinct with all known Scrophularia species in its unique deeply double serrate leaf margin with 3–7 big teeth on each side. Molecular phylogenetic analysis further supports its species delimitation and suggests a close relationship with several Japanese and North American species.

The 35 previously described species (including 4 junior synonyms) of the New World erythroneurine leafhopper genus Zyginama are reviewed and descriptions are provided for 43 new species, 2 from U.S.A., 26 from Mexico, 1 from Panama, and 14 from the Amazon region of South America. The following new synonyms are recognized: Z. aucta (McAtee) equals Erythroneura bilocularis Van Duzee, syn. n., and E. inclita Beamer, syn. n.; Z. nicholi (Beamer) equals E. canyonensis Beamer, syn. n., and E. ales Beamer, syn. n. Separate keys are provided for identification of males from North and South America, all known species are illustrated, and data on their distributions are summarized. Phylogenetic analysis of 40 morphological characters of the 71 species for which males are known yielded a reasonably well resolved estimate of relationships among the included species, but branch support was low overall.

Rhynchocephalian lepidosaurs, though once widespread worldwide, are represented today only by the tuatara ( Sphenodon ) of New Zealand. After their apparent early Cretaceous extinction in Laurasia, they survived in southern continents. In South America, they are represented by different lineages of Late Cretaceous eupropalinal forms until their disappearance by the Cretaceous/Palaeogene (K/Pg) boundary. We describe here the only unambiguous Palaeogene rhynchocephalian from South America; this new taxon is a younger species of the otherwise Late Cretaceous genus Kawasphenodon . Phylogenetic analysis confirms the allocation of the genus to the clade Opisthodontia. The new form from the Palaeogene of Central Patagonia is much smaller than Kawasphenodon expectatus from the Late Cretaceous of Northern Patagonia. The new species shows that at least one group of rhynchocephalians not related to the extant Sphenodon survived in South America beyond the K/Pg extinction event. Furthermore, it adds to other trans-K/Pg ectotherm tetrapod taxa, suggesting that the end-Cretaceous extinction affected Patagonia more benignly than the Laurasian landmasses.

Morphological characters of adults of the treehopper subfamily Nicomiinae Haupt, 1929 (Hemiptera, Membracidae) including seven genera (Eudonica gen. nov.; Euwalkeria Goding, 1926; Holdgatiella Evans, 1962; Nicomia Stål, 1858; Nodonica Dietrich, McKamey& Deitz, 2001; Stalomia gen. nov.; and Tolania Stål, 1858) and 22 species (16 new) are described and illustrated. Keys are provided for genera and for species of Euwalkeria, Holdgatiella, and Nicomia. Nomenclatural changes, based on study of the primary type material of 15 species, include three new combinations, one new synonymy, and reinstatement of one junior synonym. Eudonica has one species, Eudonica nanella sp. nov.; Euwalkeria has five species, including four new species: E. colorata sp. nov., E. distincta sp. nov., E. perdita sp. nov., E. rubrica sp. nov.; Holdgatiella has two species, one of which is described as new: Holdgatiella chiloensis sp. nov.; Nicomia has twelve species, nine of which are described as new: N. buccina sp. nov., N. harenosa sp. nov., N. inscripta sp. nov., N. jucunda sp. nov., N. monticola sp. nov., N. nigrifasciata sp. nov., N. notidana sp. nov., N. pulchella sp. nov., N. serrata sp. nov.; Nodonica has one species, Nodonica bispinigera Dietrich, McKamey & Deitz; and Stalomia has one species, Stalomia veruta sp. nov. Tolania contains eleven previously described species and nearly 60 new species, which will be treated in a later publication. Three new combinations are proposed: one species described in Nicomia is placed in the tribe Abelini (Centrotinae) as Abelus retrospinosus (Lethierry) comb. nov.; one species previously placed in Nicomia is transferred to the genus Tolania as T. obliqua (Walker, 1858), comb. nov.; one species described in Holdgatiella is placed in the genus Tolania as T. stria (Cryan & Deitz, 2002), comb. nov. One new synonymy is proposed: Hoplophera [sic] cicadoides Walker, 1862, syn. nov., a junior synonym of Nicomia interrupta Stål, 1858. Nicomia subfasciata Stål, 1858, is reinstated. The results of a phylogenetic analysis based on morphology are presented, illustrating the hypothesized relationships among species and genera of Nicomiinae. The analysis supports the broader concept of Nicomiinae proposed here. The monophyly of this group is supported by eleven characters, and all of the included genera are also monophyletic.

Neochloroglyphica gen. nov. and its type species N. perbella sp. nov. are described from Yunnan, China. Morphological characters and molecular phylogenetic analysis, based on one mitochondrial and three nuclear genes, support the hypothesis that Neochloroglyphica is a member of the tribe Neohipparchini, and that it is a sister genus to Chloroglyphica. Morphological characters, including those of the genitalia, are figured and compared with related genera, especially Chloroglyphica, Neohipparchus and Chlororithra. Diagnoses for the genus and the species are provided and illustrations of external features and genitalia are presented.

The present paper contains descriptions of two new species and one new genus: Latinopsis patagonica gen. nov., sp. nov., and Candona quasiincarum sp. nov. Both species were collected during a two-month Franco-Chilean expedition to Madre de Dios archipelago in January and February 2006. The following new systematic arrangements are proposed: L. anisitsi (Daday, 1905) comb. nov., L. columbiensis (Mehes, 1914) comb. nov., and L. falclandica (Vavra, 1898) comb. nov. Latinopsis anisitsi is redescribed from the type material and a lectotype is designated. Two species are excluded from the subfamily Candoninae, one of which is Danielocandona albida (Sars, 1901). After examination of the type material the species is reclassified as Neocypridopsis albida (Sars, 1901) comb. nov. A checklist of the known species of Candoninae of South America and the West Indies is provided.

A complete revision of the world species of the genus Phaenoglyphis Förster, 1869 has been conducted. A total of 25 species of Phaenoglyphis are valid after studying their type material. Two new species are described: Phaenoglyphis belizini sp. n. and Phaenoglyphis palmirae sp. n. Two species are synonymized: P. dolichocera (Cameron, 1889) with P. nigripes (Thomson, 1877) and P. pecki Andrews, 1978 with P. villosa (Hartig, 1841). Phaenoglyphis bangalorensis Kurian, 1953 was considered as incertae sedis. Phaenoglyphis duplocarpentieri (Kieffer, 1904) and P. hedickei Hedicke, 1928 are considered lost. Other three species are discarded as valid species because they are missing important parts without which the species cannot be defined: P. cincta (Hartig, 1841), P. frigidus (Belizin, 1968) and P. repentinus Belizin, 1962. A complete redescription and an illustrative plate are presented. A key to species of the genus Phaenoglyphis is given. Phylogenetic analysis based on morphological characters has been performed.
