Quinze espèces dont deux nouvelles pour la Science ont été récoltées en Nouvelle-Calédonie. La plupart d'entre elles sont aussi connues de l'Australie et de l'Indonésie. Une seule espèce est considérée comme faisant partie d'une faune tempérée australe. Toutes les autres sont d'affinités tropicales.
Quinze espèces d'ascidies Phlébobranches ont été récoltées dans le lagon de Nouvelle-Calédonie. Elles appartiennent à quatre familles: Corellidae, Ascidiidae, Perophoridae et Cionidae. Cette dernière n'avait pas encore été signalée de cette région. Quatre espèces sont nduvelles pour la science: Diazona textura (Cionidae), Ascidia dorsalis (Ascidiidae), Ecteinascidia aequale et E. koumaci (Perophoridae). Seules cinq espèces (une Corellidae et quatre Ascidiidae) étaient déjà connues de Nouvelle-Calédonie.
The 20 species of Neogene Scleractinia in the suborders Caryophylliina and Dendrophylliina known from the Dominican Republic are revised and illustrated. This research was based on 1590 specimens obtained primarily from the collections of the Naturhistorisches Museum, Basel, Switzerland; National Museum of Natural History, Smithsonian Institution, Washington, DC, U.S.A.; and Tulane University, New Orleans, LA, U.S.A. Eight new records are reported for the Neogene of the Dominican Republic, including four new species: Antillocyathus alatus, Trochocyathus chevalieri, T. duncani, and Paracyathus sinuosus. Special attention is given to the genus Asterosmilia, since half (five) of the known species in this genus occur in the Dominican Republic. Most species described herein are assumed to constitute a deep-water fauna by analogy to depth ranges of the same or similar species known from the Recent. Certain localities and parts of formations are inferred to represent deep-water (> 200 m) facies. These inferences may aid in the paleoecological interpretation of other fossils collected from these areas.
Multivariate statistical procedures are used to distinguish species in the reef-coral genus Stephanocoenia through a continuous Neogene sequence (five-million year time interval) in the Cibao Valley of the northern Dominican Republic. This genus is the only member of the family Astrocoeniidae that occurs in the sequence. The material consists of 56 colonies (17 of which are measured) from 24 localities in four river sections, the most important being Rio Gurabo and Rio Cana. Ten characters are measured on each of 10 corallites per colony. The data are analyzed using cluster and canonical discriminant analysis to group colonies into clusters representing species. Identical measurements on modem colonies collected near Discovery Bay, Jamaica are included for comparison. Two fossil species are defined in the analysis, one of which is new (Stephanocoenia duncani, n. sp.). Both species are significantly distinct from the single modem species (S. intersepla) that is the sole living representative of the genus. Study of collections from other reef localities shows that both fossil species occur only during Neogene time and only at a limited number of localities. Patterns within each species are traced up a composite stratigraphic section using nonparametric statistical analyses. One of the two fossil species (S. spongiformis) is found to remain stable through time, whereas the other (S. duncam) changes its morphology in a direction approaching the cluster for the modem species. Further study of patterns of variation within the one modern and two fossil clusters shows that intraspecific variation is unusually complicated in this genus. The clusters overlap, and colonies within each cluster differ widely. Variation between populations within the modem species occurs in the same characters as those which distinguish the modem species from the fossil species converging with it (S. duncam). However, these two species form a morphologic continuum that cannot be explained by environment alone. Therefore, they may represent two gradually intergrading chronospecies within one lineage. Of the two fossil species of Stephanocoenia defined, one species (s. spongiformis) exhibits an evolutionary pattem similar to that observed in the family Poritidae. In this pattern, species were found to have short durations and stable morphologies and to have become extinct during the mid- to late Pliocene through early Pleistocene mass extinction. In contrast, the second species of Slephanocaenia (S. duncam) may have evolved over a long time period, possibly forming chronospecies that survived the mass extinction. Unlike genera in the Poritidae, however, no radiation of taxa occurred in the genus after the extinction event. Since no consistent relationship has been discovered between morphology and environment in these corals with the data at hand, their paleoecologic value can only be determined after data on more taxa are collected, and their associations with other corals are studied. This study represents part of a multidisciplinary project on the stratigraphy and paleontology of the northern Dominican Republic, coordinated by P. Jung and J. B. Saunders of the Naturhistorisches Museum Basel, Switzerland.
This paper describes the effect of the "Boleslaw" mining and metallurgic complex in Bukowno near Olkusz on the vegetation of the fresh coniferous forest association Vaccinia myrtilli-Pineitum. The increase in concentration of zinc, lead and cadmium in selected plant species under the influence of industrial emission, and the dependence of this increase upon the magnitude of dust fall and site conditions, are analized. The extent of accumulation of heavy metals in plants was assumed to be an indicator of the degree of pressure exerted by the industrial complex. The degradation of fresh coniferous forest was. increasing along with an increase in this pressure. The species composition of the association, and the quantitative relations among species representing various site types underwent considerable changes. In patches extremely degraded, the plant species characteristic of poor sandy grass-lands gained predominance over forest plants.
This synonymic list of the flat bugs (Aradidae) ofthe world enumerates 1,798 species in 211 genera. Names of eight fossil species are given in their original combination in modern genera. The list is introduced by brief discussions of habits, food, ecology and distribution. Many taxonomic innovations are included, as follows: Subfamily Chinamyersiinae is divided into two new tribes, Chinamyersiini and Tretocorini; the subfamily Prosympiestinae is divided into two new tribes, Llaimacorini and Prosympiestini. All currently recognized subgenera are raised to generic rank: Aneurillus, Breviscutaneurus, lralunelus, and Paraneurus from Aneurus; Miraradus and Quilnus from Aradus; Lissaptera and Nesiaptera from Acaraptera; Neoproxius and Nesoproxius from Proxius (see list below for new combinations resulting). Three genus-group names are raised from synonymy: Aneurosoma; Burgeonia and Brachyrhynchus. One genus-group name is reduced to synonymy; Zimera as a junior synonym of Brachyrhynchus. The following new species-genus combinations are made, these mostly resulting from elevation of subgenera to generic status or species transfers. In Aneurillus - borneensis, cetratus, cheesmanae, consimilis, doesbergi, foliaceus, glaberrimus, gracilis, jacobsoni, longicollis, papuasicus, pumilus, superbus; in Aneurosoma - dissimile; in Aneurus - septentrionalis; in Aradus - dignatus; in Arbanatus - asiaticus, loriae; in Brachyrhynchus - affinis, amplicollis, andamanensis, angolensis, armigerus, australis, bergrothi, bergrothianus, bhoutanensis, breuiceps, burmensis, confectus, confusus, consimilis, crenatus, dentipes, discrepans, dispar, duboisi, elegans, exarmatus, funebrus, furcatulus, furcatus, germari, gracilicornis, granos us, hospidus, hoberlandti, horridus, hsiaoi, incisus, incognitus, insignis, intermedius, javanensis, kachenensis, kerzhneri, lindemannae, longicornis, longirostris, luberoensis, luzonicus, machadoi, madagascariensis, mauricii, membranaceus, micronesicus, monedulus, mario, ouerlaeti, parallelus, pauper, philippinensis, piliferus, poriaicolus, projectus, quadridentatus, quadrispinosus, rossi, rugosus, scrupulosus, serratus, similis, solomonensis, spinipes, stolidus, subinermis, subtriangulus, sulcatus, sulcicornis, sumatrensis, taiwanicus, teter, thailandicus, triangulus, tristis, urijdaghi; in Breviscutaneurus - breviscutatus, helenae, madagascariensis, medioscutatus; in Burgeonia - burgeon, dilatatus, froidebisei, intermedius, kormileui, madagascariensis, maynei, paruus, schoutedeni, usingeri; in Chiastoplonia - pusio; in lralunellus - aibonitensis, bergi, bispinosus, boliuianus, carioca, costariquensis, flavomaculatus, ftitzi, gallicus, leptocerus, longicornis, marginalis, monrosi, plaumanni, politus, sahlbergi, simulans, subdipterous, tenuis, westwoodi, wygodzinsky; in Miraradus - foliaceus, himalayensis, mirabilis, oeruendetes; in Neoproxius - amazonicus, carioca, costariquensis, gypsatus, incaicus, lindemannae, magdalenae, nicaraguensis, palliatus, panamensis, personatus, peruuianus, schwarzii; in Nesiaptera - denticulata, gibbosa, ouata, rotundata, tuberculata, zimmermani; in Nesoproxius - angulatus, constrictus, gracilis, hexagonalis, malayensis, minutus, punctulatus, vietnamensis, yoshimotoi; in Neuroctenus - ghesqueri; in Oreossa - insignis; in Quilnus - amurensis, breuirostris, discedens, heidemanni, niger, nigrinus, oregonicus, paruicollis, subsimilis, usingeri. Three new species names are proposed: Brachyrhynchus pauper for the preoccupied Mezira modesta Kormilev, 1972; Mezira uicina for the preoccupied Mezira proxima Kormilev, 1982; and Mezira doesburgi for the preoccupied Mezira surinamensis Kormilev, 1974. Five new species-synonymys are made: Aradus centriguttatus as a junior synonym of Aradus similis; Mezira jacobsoni as a junior synonym of Daulocoris cornigerus; Mezira modesta as a junior synonym of Brachyrhynchus membranaceus; Neuroctenus breuicornis as a junior synonym of Neuroctenus ater; Notoplocaptera malaisei as a junior synonym of Zoroaptera malaisei. Four new emendations of gender endings are proposed for the species name "halaszfyi": Artabanus halaszfyae, Chelysosoma halaszfyae, Ctenoneurus halaszfyae, Mezira halaszfyae.
