A taxonomic revision of the cichlid genus Astatoreochromis is presented. Eighteen meristic and 23 morphometric measurements were taken on 185 individuals, including type specimens. While fin counts separate populations from the Lake Victoria region (Astatoreochromis alluaudi) from those of the Rusizi and Malagarazi rivers in the Lake Tanganyika basin (A. vanderhorsti and A. straeleni respectively), clear differentiation was not detected between the latter two. Mann-Whitney U-tests on specimens of comparable size from the two Tanganyika populations revealed significant differences in specimens < 75 mm SL, mainly in pharyngeal jaw proportions, but also in some other measurements on the head and body. However, these differences were not detected in specimens > 75 mm SL and Astatoreochromis vanderhorsti is herein considered a junior synonym of A. straeleni. A redescription of the two valid species of Astatoreochromis, A. alluaudi and A.straeleni, is provided.
A preliminary study has been made for Borail Wild Life Sanctuary, Assam, India. A total of 25 species of liverwort (Marchantiophyta) and one species of hornwort (Anthocerotophyta) have been enumerated. Of these, Frullania berthoumieuii is new to India, Caudalejeunea reniloba new to North East India, 13 species new to Assam and 11 species are reported for the first time from Borail WLS. Folioceros paliformis is rediscovered after its type.
Literature about Mesitiinae Kieffer, 1914 has not been treated extensively from a taxonomic viewpoint in comparison with other subfamilies in Bethylidae Latreille, 1802. Our research on species of Metrionotus Móczár, 1970, Clytrovorus Nagy, 1972 and Sulcomesitius Móczár, 1970 revealed a new hypopygium shape pattern, namely a 'star-shaped' hypopygium, which is characteristic of a new genus, Astromesitius gen. nov., with two new species Astromesitius thionyi gen. et sp. nov. and Astromesitius olavoi gen. et sp. nov. The descriptions of both new species are based on male specimens collected in Thailand and the United Arab Emirates. Astromesitius quatei (Móczár, 1977) gen. et comb. nov. is designated as type species for the new genus, which is erected for a total of seven species. The main diagnostic characteristics are the head longer than wide; a clypeus with a median lobe quadrate; an antenna with distinct long setae, with pedicel caliciform, and with flagellomeres long and caliciform; pronotum and anteromesoscutum with longitudinal sulcus indistinct or absent; metapectal-propodeal complex with posterior projection hardly distinct or absent; hypopygium star-shaped; genitalia with aedeagus slender and fusiform.
Two new junior synonyms, Pseudomesitius Duchaussoy, 1916 syn. nov. and Triglenus Marshall, 1905 syn. nov., for the genus Bradepyris Kieffer, 1905 are proposed and a new diagnosis for the genus is given. Two new species (based on males) from the Saharo-Arabian region are here described: Bradepyris jordanicus, sp. nov. and B. baleariensis, sp. nov. A brief revision, with a key to the males and females of all species of this genus, and the first male genitalia descriptions are also provided.
Cnestus mutilatus (Blandford) (Coleoptera: Curculionidae: Scolytinae) is reported from Pennsylvania for the fi rst time, new state record. Specimens were collected using baited Lindgren funnels as early as 2013. Within Pennsylvania, C. mutilatus is now reported from Berks, Bucks, Lehigh, Montgomery, and York Counties.
Cixidia fusca and Synecdoche impunctata (Hemiptera: Achilidae) are reported from Missouri for the first time, new state records. Ecological and trapping information is also provided.
Sehen sich Banken mit Engpässen auf einem Finanzierungsmarkt konfrontiert, weichen sie auf andere Finanzierungsquellen aus, was den Wettbewerb verschärft: Banken, die nicht direkt vom eigentlichen Finanzierungsengpass betroffen sind, können ebenso davon erfasst werden, was sich stark auf die Realwirtschaft auswirkt.
The fouling serpulids (Polychaeta: Serpulidae) from United States coastal waters: an overview
(2017)
Serpulids are an important component of fouling communities. This paper provides an overview of the serpulid species found in North America, as part of a broader study of fouling invertebrates focused on NIS (non-indigenous species) in United States coastal ecosystems. Almost 4400 serpulid specimens were examined from selected fouling plates. Fouling plates were deployed in 26 bays and coastal lagoons along the continental coasts of the United States and Hawaiian islands, primarily in bays and lagoons with salinities averaging 20‰ or greater. Twenty-five serpulid species were identified, including four new records for the United States (Ficopomatus uschakovi, Hydroides cf. brachyacantha, H. longispinosa and Protula longiseta), three known NIS, two presumed NIS, three cryptogenic serpulids, and several range extensions. Crucigera websteri extends its northward range from Santa Barbara Island to Humboldt Bay, California; Ficopomatus enigmaticus, first recorded in North America from San Francisco, California in 1920, Rockport, Texas in 1952 and Barnegat Bay, New Jersey in 1980, is now recorded at additional localities on the east coast (Chesapeake Bay, Virginia, Charleston, South Carolina and Indian River, Florida) and the northern Gulf of Mexico (Galveston Bay, Texas); F. miamiensis extends its westward range from Louisiana to Texas; F. uschakovi, an Indo-Pacific and Western African species, was recorded formally for the first time from the northern Gulf of Mexico ((Galveston Bay and Corpus Christi, Texas) and the east coast of Florida (Jacksonville). Hydroides cf. brachyacantha extends its northward range from Curaҫao to Pensacola Bay, Florida; H. dirampha from Veracruz, Mexico to Corpus Christi, Texas; H. floridana extends its westward range from Louisiana to Texas; H. gracilis extends its northward range from Pacific Grove to San Francisco, California; Salmacina huxleyi from Cape Hatteras, North Carolina to Rhode Island; and Spirobranchus minutus from Veracruz, Mexico to Pensacola Bay, Florida. The following additional species range extensions are provisional in that they represent only one record or were not found in the most recent surveys (e.g., Hydroides elegans - east coast): H. longispinosa from Marshall Islands to Oahu, Hawaii; Protula balboensis from Florida to Texas; P. longiseta from the Mexican Caribbean to the Indian River, Florida; H. elegans from San Francisco to Humboldt Bay, northern California and on the east coast from the Indian River, Florida, to Cape Cod, Massachusetts. Among surveyed bays, Biscayne Bay, Florida and Corpus Christi, Texas (northern Gulf of Mexico) had the greatest number of species (14 and 8, respectively); in contrast, almost all sites in Alaska, Washington, Oregon (northwest Pacific), Rhode Island, Virginia and South Carolina (Atlantic) had only one or two species each. Hydroides dianthus was, by far, the most abundant serpulid species on fouling plates in the northern Gulf of Mexico and the east coast, while Pseudochitinopoma occidentalis was the most abundant serpulid detected on the west coast. For each species recorded herein, we include the synonyms and some key references, a material studied section, a diagnosis, and updated distributional information. A checklist and identification key to the known shallow-water serpulids sensu stricto of the United States are included.
Das Laubmoos Hylocomium umbratum war aus Sachsen nur von einem Fundort im Westerzgebirge aus dem Jahre 1801 bekannt. Nach fast 200 Jahren konnte die Art im Jahr 2000 wiederbestätigt und in der Folgezeit an zahlreichen weiteren Stellen nachgewiesen werden. Mögliche Zusammenhänge zur aktuellen Veränderung von Umweltfaktoren werden dargestellt und der Ausbreitungstrend der Art im Kontext zu derzeitigen Entwicklungstendenzen der Waldbodenflora im Erzgebirge diskutiert.
