Oldest webspinners from the Middle Jurassic of Inner Mongolia,China (Insecta: Embiodea)

The oldest webspinners, Sinembia rossi gen. et sp. nov. and Juraembia ningchengensis gen. et sp. nov. , are described in the new family Sinembiidae fam. nov. from the Middle Jurassic of Inner Mongolia, China. They differ from the Cretaceous and more recent Embiodea in several plesiomorphic characters, namely they have a long ovipositor, three‐segmented cerci, eyes situated on the posterolateral angles of the head, and the prothoracic prescutum is absent: these characters suggest habits that strongly differ from those of the recent taxa. The loss of the ovipositor and the reduction in the number of cerci can no longer be considered as synapomorphies of the ((Embiodea + Zoraptera) + Plecoptera) and (Embiodea + Zoraptera) clades, respectively.

On the fauna of bristletails of the genera <Emphasis Type="Italic">Petrobius</Emphasis> and <Emphasis Type="Italic">Trigoniophthalmus</Emphasis> (Thysanura,Machilidae) from the Caucasus

Five new species, Petrobius caucasicus sp. n., Trigoniophthalmus presimplex sp. n., T. divnogorski sp. n., T. kislovodski sp. n., and T. adigei sp. n. (Machilidae), are described from the Caucasus. A key to all the known species of the genus Trigoniophthalmus is given. Two subgenera (Trigoniophthalmus s. str., Trigoniocellus subgen. n.) in the genus Trigoniophthalmus are described. 2 + 2 retractile vesicles are present on abdominal segments II–IV in the species of Trigoniocellus subgen. n. and on II–V abdominal segments in Trigoniophthalmus s. str. Analysis of the evolution and phylogenetic relations between the species of the genus Trigoniophthalmus is performed for the first time. The formation of bristletails of the genus Trigoniophthalmus appears to occur in the Caucasian mountain province of the European area, from where they penetrated to the Central European mixed province and the Mediterranean subarea. Among the described species of the genus, T. kislovodski is distinguished by the greatest number of plesiomorphic states of morphological characters.     

Four new species of Typhlocharis (baetica group) (Coleoptera: Carabidae: Anillini) from southwestern Iberian Peninsula with notes on their biogeographical and morphological implications

Four new species of Typhlocharis (Carabidae: Anillini) are described from the southwest of the Iberian Peninsula, assigned to the baetica species group. T. prima sp.n. , T. secunda sp.n. and T. tertia sp.n. (from La Palma del Condado, Huelva, Spain) are syntopic, and T. quarta sp.n. (from Barrancos, Beja, Portugal) is the first species of the group with umbilicate series 4 + 4. They represent, respectively, the southernmost and westernmost distribution data for the group. The baetica group remains well defined and includes ten species. The diagnosis is simplified, with the confirmation that many morphological features characteristic of this group are widespread within the genus. The defining character is the presence of denticles in apical margin of elytra, not associated to the seventh stria or to the elytral suture. The new species provide morphological data that suggest the baetica and silvanoides groups are closely related. Distribution of both groups in the south of the Iberian Peninsula and the presence of morphological characters that are considered plesiomorphic are coherent with the hypothesis of betic‐riffain origin of the genus. They also support the hypothesis of easy alteration of the umbilicate pattern between closely related species and the independent origin of apical denticles in the group compared with those present in other species of the genus. The presence of three well‐differentiated size ranges in syntopic populations suggest ecological diversification to avoid interspecific competition.     

Two New Species of Abyssal Pogonophores from the Antarctic Ocean

Two new species of the genus Polybrachia Ivanov, Polybrachia macrolamellosa sp. n. and P. romanovi sp. n., found at two stations in the Atlantic sector of the Antarctic Ocean on cruises 11 and 43 of the R/V Akademik Kurchatov (1971 and 1985–1986) are described. The material was collected in the Scotia Sea (off northern Elephant Isle, at a depth of 3110 m) and in the South Sandwich Trench (8004–8116 m). The main distinctive features of the new species are the extremely large cuticular plaque (up to 88 µm in maximum diameter) on the trunk metameric papillae in P. macrolamellosa sp. n. and the very long cephalic lobe (L_cl/D_f is about 2) in P. romanovi sp. n.Original Russian Text Copyright ¢ 2005 by Biologiya Morya, Smirnov.     

Revision of the Acanthoclinidae (Pisces: Perciformes), with descriptions of a new genus and five new species

Abstract

The family Acanthoclinidae includes 10 species: Acanthoclinus fuscus Jenyns, 1842; Taumakoides littoreus ((Forster) Bloch & Schneider, 1801); T. rua n. sp.; T. marilynae n. sp.; T. matti n. sp.; Belonepterygion fasciolatum (Ogilby, 1889); Beliops xanthokrossos n. gen. et sp.; Acanthoplesiops indicus (Day, 1888); A. hiatti Schultz, 1953; and A. psilogaster n. sp. Acanthoclinus quadridactylus (Bloch & Schneider, 1801) and A. trilineatus Griffin, 1933, are reduced to synonymy under Taumakoides littoreus ((Forster) Bloch & Schneider, 1801).

Osteological and morpological character states, between and within genera, suggest that Acanthoclinus and Taumakoides are close to the stock from which the family is derived. There is also compelling evidence that T. matti is the least specialised species of Taumakoides. Progressive specialisation is evident in the remaining genera, with Acanthoplesiops being the most highly specialised.

The family occurs primarily in shallow waters of the Indian and western Pacific oceans; most of the species are found about New Zealand. The centre of origin of the Acanthoclinidae was probably on the Indian-Australian Plate (which includes the New Zealand continental shelf). Acanthoplesiops hiatti and A. indicus are considered to be endemics of the Pacific and African plates, respectively.

A key to species is included.

A new species of Angelopteromyia Korneyev, 2001 (Diptera,Platystomatidae) from Iran,with the key to the species

Angelopteromyia korneyevi Mohamadzade Namin, sp. n. from Iran is described and figured. The new species is similar to other species of Angelopteromyia in having abdominal spiracles 5 of females not approximated medially, as well as clypeus extended postero-ventrally, antenna shorter than face, and R₁ and R₄₊₅ setulose on dorsal side. It differs from other species of Angelopteromyia by having mostly brown wing with 3 hyaline crossbands and a few hyaline spots, and dark brownish basal and costal cells without hyaline spots.     

Anobiidae (Coleoptera) of the Kermadec Islands

Abstract

Lasioderma serricorne (Fabricius), Leanobium marmoratum (Lea), Leanobium flavomaculatum n.sp., Serianotus punctilatera kermadecensis n.ssp., and Dorcatomiella ornata Español are recorded from the Kermadec Islands. This fauna is relatively poor, probably because of the small size and limited diversity of the islands. Affinities are with New Zealand (L. flavomaculatum), Norfolk Island (L. marmoratum), and Lord Howe Island (S. punctilatera kermadecensis). D. ornata is strongly endemic, though other species of Dorcatomiella occur on the Marianas and Tahiti.

All are noteworthy for being small.     

Isolation of endophytic actinomycetes from selected plants and their antifungal activity

The isolation of endophytic actinomycetes from surface-sterilized tissues of 36 plant species was made using humic acid–vitamin (HV) agar as a selection medium. Of the 330 isolates recovered, 212 were from roots, 97 from leaves and 21 isolates from stems with a prevalence of 3.9, 1.7 and 0.3%, respectively. Identification of endophytic actinomycetes was based on their morphology and the amino acid composition of the whole-cell extract. Most isolates were classified as Streptomyces sp. (n = 277); with the remainder belonging to Microbispora sp. (n = 14), Nocardia sp. (n = 8) and Micromonospora sp. (n = 4). Four isolates were unclassified and 23 were lost during subculture. The most prevalent group of isolates were the Streptomyces sp. occurring in 6.4% of the tissue samples of Zingiber officinale. Scanning electron microscopy investigation of this plant revealed that 7.5% of the root and 5% of the leaf samples contained endophytes. Three of the Streptomyces sp. isolates strongly inhibited Colletotrichum musae, five were very active against Fusarium oxysporum and two strongly inhibited growth of both test fungi.
