Two new species of Brazilian Psychoda Latreille are described, and Psychoda alternata Say and P. zetoscota Quate are recorded for the first time from Brazil. Psychoda divaricata Duckhouse, already described from southern Brazil, was recorded in the northeastern part of that country, as well as in the eastern Amazon region. The supraspecific classification proposed for the species of Psychoda according to Quate (= Psychodini of Jeñek) are discussed. A new classification is suggested that considers only one genus, Psychoda, divided into 12 subgenera: subgenus Psychoda Latreille, subgenus Copropsychoda Vaillant, subgenus Falsologima Jeñek & Harten, subgenus Psychodula Jeñek, subgenus Psychomora Jeñek, subgenus Psychana Jeñek & Harten, subgenus Logima Eaton, subgenus Tinearia Schellenberg, subgenus Chodopsycha Jeñek, subgenus Ypsydocha Jeñek, subgenus Psychodocha Jeñek, and subgenus Psycha Jeñek. A list of the Psychoda species from Latin America and the Caribbean region is presented.

One New Species

The genus-level classification of New World Erythroneurini is revised based on results of a phylogenetic analysis of 100 morphological characters. The 704 known species are placed into 18 genera. Erasmoneura Young and Eratoneura Young, previously treated as subgenera of Erythroneura Fitch, and Erythridula Young, most recently treated as a subgenus of Arboridia Zachvatkin, are elevated to generic status. Three species previously included in Erasmoneura are placed in a new genus, Rossmoneura (type species, Erythroneura tecta McAtee). The concept of Erythroneura is thereby narrowed to include only those species previously included in the nominotypical subgenus. New World species previously included in Zygina Fieber are not closely related to the European type species of that genus and are therefore placed in new genera. Neozygina, n. gen., based on type species Erythroneura ceonothana Beamer, includes all species previously included in the “ceonothana group”, and Zyginama, n. gen., based on type species Erythroneura ritana Beamer, includes most species previously included in the “ritana group” of New World Zygina. Five additional new genera are described to include other previously described North American Erythroneurini: Hepzygina, n. gen., based on type species Erythroneura milleri Beamer and also including E. aprica McAtee; Mexigina, n. gen., based on type species Erythroneura oculata McAtee; Nelionidia, n. gen., based on type species N. pueblensis, n. sp., three additional new species, and Erythroneura amicis Ross; Neoimbecilla, n. gen., based on type species Erythroneura kiperi Beamer and one new species; and Illinigina, n. gen., based on type species Erythroneura illinoiensis Gillette. Five new genera, based on previously undescribed species, are also recognized: Aztegina, n. gen, based on A. punctinota, n. sp., from Mexico; Amazygina, n. gen., based on type species A. decaspina, n. sp., and three additional new species from Ecuador; Hamagina, n. gen., based on type species H. spinigera, n. sp., and two additional new species from Peru and Ecuador; Napogina, n. gen., based on type species N. recta, n. sp., and one additional new species from Ecuador; Perugina, n. gen., based on type species P. denticula, n. sp., from Peru; and Spinigina, n. gen., based on type species S. hirsuta, n. sp., and an additional new species from Peru. Phylogenetic analysis suggests that the New World Erythroneurini consist of three lineages resulting from separate invasions from the Old World.

Recent sampling of seamount and ridge habitats in the New Zealand Exclusive Economic Zone has yielded new cyclostome bryozoan taxa. We describe here one new genus, a new name, Dartevellopora (to replace the generic homonym Dartevellia Borg, 1944) and ten new species, comprising Filicisparsa albobrunnea n. sp. (Oncousoeciidae), Discantenna tumba n. gen., n. sp. (Diastoporidae), Supercytis gracilis n. sp. (family incertae sedis), Filifascigera brevicaudex (Frondiporidae); Plagioecia parva n. sp. (Plagioeciidae), Favosipora bathyalis n. sp. (Densiporidae), and Dartevellopora neozelanica n. sp., D. rugosa n. sp., Disporella minicamera and D. minutissima n. sp. (Lichenoporidae). Seven of the new species occurred in the “Graveyard Seamount Complex” on the north-central Chatham Rise to the east of the South Island. Of these, three species and one new genus are known only from the type locality on “Graveyard” Seamount ― the most intensively fished of the seamounts in the complex by heavy bottom-trawl gear, which has implications for species conservation. Evidence based on discrimination between benthic invertebrate assemblages of hard bottoms on fished and unfished seamounts in the area suggests that small, short-lived taxa like cyclostome bryozoans might not be disadvantaged by bottom-trawling.

AbstractTwo new species, Tachinus beckeri from northwestern British Columbia and southern Yukon Territory and T. californicus from southern California, are described and their major diagnostic characters illustrated with line drawings and scanning electron photomicrographs. Tachinus jacuticus campbelli is placed in synonymy with T. jacuticus jacuticus and a new subspecies, T. jacuticus ullrichi, from Quebec and Labrador is named. Tachinus thruppi Hatch is removed from synonymy with T. frigidus and considered a valid species. Both T. thruppi and T. frigidus are redescribed and illustrated. A new, revised key to the species of Tachinus is included.New distributional data are presented for 40 species and new or revised distributional maps are presented for 24 species. Changes in classification of Tachinus proposed by Ullrich in his revision of the world species are reviewed and those that are accepted are incorporated into a revised classification of the North American species. These changes are included in a check list of the North and Central American species of the genus.

The spider genus Nops MacLeay is revised, with redescriptions of 22 previously known species and descriptions of 12 new species. A new diagnosis for the genus is provided and keys to separate the species are proposed. After this revision Nops includes 34 extant species, thereof 15 (44%) occur in the Caribbean Islands, four (12%) in Central America and 15 (44%) in South America. Females of Nops meridionalis Keyserling and Nops gertschi Chickering are found and described for the first time. Three new synonymies are proposed: Nops virginicus Sánchez–Ruiz with Nops blandus Bryant, Nops craneae Chickering with Nops maculatus Simon and Nops proseni Birabén with Nops farhati Prosen. Four species are considered inquerenda: Nops anisitsi Strand, Nops bellulus Chamberlin, Nops branicki (Taczanowski) and Nops glaucus Hasselt. The following new species are described: N. jaragua n. sp., N. navassa n. sp., and N. pallidus n. sp. from the Caribbean region; N. campeche n. sp. and N. tico n. sp. from Central America, and N. alexenriquei n. sp., N. amazonas n. sp., N. bahia n. sp., N. ipojuca n. sp., N. itapetinga n. sp., N. minas n. sp. and N. pocone n. sp. from South America. New geographical records and distribution maps are provided for all species, with illustrations and reviewed diagnoses. The Nops species are restricted to the Neotropical region, from the Caribbean Islands and Mexico to the north of Argentina. The highest species richness is concentrated in the Wider Caribbean Region, including Central America and the north of Colombia and Venezuela where 64.7% of the species occur. Endemism in the Caribbean islands is very high; most of these species are single island endemics. A cladistic analysis, based on morphological data, was executed to test the monophyly of the genus. This is the first cladistic analysis of Caponiidae, and it includes besides the Nops species, 1) the six other species that were transferred from Nops, now in the genera Orthonops, Cubanops, Tarsonops and Medionops, and 2) Nopsides ceralbonus Chamberlin and Nyetnops guarani Platnick & Lise. Therefore, representatives of all known Nopinae genera are included in the ingroup. The data matrix comprises 41 taxa scored for 47 morphological characters. The analyses under equal weights resulted in six equally parsimonious trees of 99 steps. All these trees are congruent with a unique hypothesis for Nopinae genera. Thus, all topological differences among the most parsimonious trees were the consequence of different hypotheses of relationships within Nops. The same result was also found under implied weighting with constants of concavity k = 2 to 13, where the topology of all trees was congruent for a single Nopinae genera hypothesis, but relationships within Nops were not resolved. All analysis under equal and implied weights recovered the monophyly of Nops with high support values, but internal clades within the genus showed low branch supports. Our results thus suggest that to resolve the internal relationships of Nops, studies based on molecular evidence are necessary to counteract the deficit of morphological data. The hypothesis obtained for Nopinae showed high branch support values for most of clades, corroborating all the transfers made from Nops. Medionops was recovered as the sister group of Nops with high support values. Nops, Medionops and Nopsides form a closely related, distinct spider group among nopine, supported by five unambiguous synapomorphies. Two of these synapomorphies could be functionally related: the presence of an arolium on the anterior pretarsi and the elongated and dorsally reflexed unpaired claw on the anterior legs. Nopsides appears to be a genus with apomorphic characters, presenting highly modified legs, but lacking the crista and gladius, and gaining a pair of anterior lateral eyes. Nyetnops is sister to all other nopine genera. Our results identified the necessity of further studies on nopine leg structures (arolium, crista, gladius and adesmatic joints) to improve understanding of the phylogenetic relationships of Nopinae genera.

The earliest known members of the Thais clade of rapanine muricid neogastropods comprise four species from the Cantaure Formation (early Miocene: Burdigalian) of Venezuela; three of these species are new. Neorapana rotundata Gibson-Smith et al., 1997, is most closely related to the Recent Pacific Mexican N. tuberculata (Sowerby, 1835), and represents the only known Atlantic occurrence of the genus. Thais brevicula new species is closest to T. callaoensis (Gray, 1828) from the Recent of northern Peru and the Galápagos. A review of the genus Thais indicates that the typical members of this group occur in the South Atlantic, West Africa, and eastern Pacific, but not in the Recent fauna of the southern Caribbean. Stramonita bifida new species is a large species related to the Recent S. haemastoma floridana (Conrad, 1837), which occurs throughout the Caribbean. A review of American species of Stramonita indicates that the taxon S. biserialis (de Blainville, 1832) from the Recent fauna of the eastern Pacific, and the taxon S. h. haemastoma (Linnaeus, 1767), may each be composed of more than one species despite the teleplanic dispersal of their larvae. Stramonita semiplicata new species is closely related to the Recent S. bicarinata (de Blainville, 1832) from the South Atlantic, and represents a lineage that occurred in the Caribbean region until at least the late Miocene. It may have given rise to the eastern Pacific genus Acanthais. The higher diversity and greater antipredatory specialization of eastern Pacific as compared to western Atlantic members of the Thais clade may have resulted from higher post-Miocene rates of speciation and lower extinction rates in the eastern Pacific.

A New Species

The classification of the superfamily Psylloidea is revised to incorporate findings from recent molecular studies, and to integrate a reassessment of monophyla primarily based on molecular data with morphological evidence and previous classifications. We incorporate a reinterpretation of relevant morphology in the light of the molecular findings and discuss conflicts with respect to different data sources and sampling strategies. Seven families are recognised of which four (Calophyidae, Carsidaridae, Mastigimatidae and Triozidae) are strongly supported, and three (Aphalaridae, Liviidae and Psyllidae) weakly or moderately supported. Although the revised classification is mostly similar to those recognised by recent authors, there are some notable differences, such as Diaphorina and Katacephala which are transferred from Liviidae to Psyllidae. Five new subfamilies and one new genus are described, and one secondary homonym is replaced by a new species name. A new or revised status is proposed for one family, four subfamilies, four tribes, seven subtribes and five genera. One tribe and eight genera / subgenera are synonymised, and 32 new and six revised species combinations are proposed. All recognised genera of Psylloidea (extant and fossil) are assigned to family level taxa, except for one which is considered a nomen dubium.
