NORTHERN RECORDS OF THE GENUS CULISETA FELT IN AUSTRALIA WITH THE DESCRIPTION OF A NEW SPECIES (DIPTERA: CULICIDAE)

i
Culiseta arenivaga sp.n., described from females from Fraser Island, Queensland, provides the northernmost record of Culiseta in Australia. C. arenivaga has postspiracular setae and it is compared in text and figures with the other species known from Queensland, C. antipodea Dobrotworsky, and with the other species possessing postspiracular setae, C. littleri (Taylor), C. inconspicua (Lee), and C. atra (Lee), of which the first two are the only species known from New South Wales. Postspiracular setae are reported in C. inconspicua for the first time. C. littleri is recorded from northern New South Wales and geographical variation in this species is discussed. The unusual palmate empodium of C. antipodea females is described and figured. Relationships within the genus are considered and an austral origin for the genus is suggested.     

New Podonominae from Japan,Boreochlus longicoxalsetosus sp. n. (Diptera: Chironomidae) with a Key to Species of the Genus

During the survey of chiromonid midges from Kyushu, the authors found a new species of Podonominae (Chironomidae), Boreochlus longicoxalsetosus. The male imago of this new species is described and illustrated. This constitutes the third record of the subfamily Podonominae, and the second species of the genus from Japan. The new species has very long notable setae lying on the dorsomedial surface distal to the volsella, which are never seen in the other Boreochlus species. A key to species of the genus in the world is given.     

山东临朐中中新世山旺组紫藤属(豆科)荚果化石的再观察

豆科紫藤属Wisteria约有5-6个现生种,间断分布于中国、日本和美国的温带地区,但化石记录表明,该属在新近纪可能广泛分布于捷克、荷兰、格鲁吉亚阿布哈兹、保加利亚、罗马尼亚、俄罗斯远东、日本和中国。因此,研究紫藤属化石有助于深入认识它的早期演化、分类、多样性、古生态和生物地理,其中荚果化石的分类价值和演化意义尤为显著。文中基于对产自山东临朐中中新世山旺组的山旺紫藤W.shanwangensis荚果化石的再观察,并结合紫藤属3个现生种——紫藤W.sinensis、藤萝W.villosa和多花紫藤W.floribunda的荚果发育特征,讨论这些化石的分类、演化、发育和埋藏学意义。结果进一步证明,山旺紫藤荚果化石与国产的2个现生种——紫藤和藤萝的荚果更为相似,呈倒披针形、种子较少和室间缢缩明显。比较而言,日本和美国产的紫藤属现生种——多花紫藤和美国紫藤W.frutescens的荚果呈线形、种子较多和室间缢缩不明显,而且日本中新世和上新世报道的紫藤属荚果化石与多花紫藤的荚果更为相似。然而,中国和日本报道的紫藤属荚果化石迄今都没发现被毛,这与现生种中最原始的美国紫藤的荚果相似,而与东亚紫藤属现生种密被绒毛的荚果形成显著差别。因此,中国、日本和美国的紫藤属种类可能早在中新世就已经发生了形态地理分化,而荚果无毛或许是该属演化过程中一个比较原始的性状;紫藤属现生种荚果在发育的中、后期果壁上具有与纵轴方向成锐角的倾斜纤维纹饰,它们在荚果完全成熟后导致果瓣沿缝线开裂并卷曲,卷曲的果瓣放入水中又能恢复平整。值得注意的是,山旺紫藤荚果化石果壁上也发现了类似的倾斜纤维纹饰,这表明它们在脱落保存时处在发育的中、后期,这一发育时期脱落的荚果更有可能保存为化石记录;山旺紫藤荚果化石果壁的碳质残片中还富含硅藻类,近似于远距直链藻Melosira distans和颗粒直链藻M.granulata这些浮游相的、生活在深水区的优势种。因此,山旺紫藤荚果脱离母体后可能沉积在湖水较深的地方,而且它也可能是在成熟开裂的状态下脱落,瓣片本来卷曲,被短程搬运至湖中,又在湖水的浸泡下恢复平整状态,而后经沉积物掩埋后形成化石。     

FILLING A GAP: THE FIRST OCCURRENCES OF EPIPHAXUM (CNIDARIA: HELIOPORACEA: LITHOTELESTIDAE) IN THE EOCENE, OLIGOCENE AND MIOCENE

Abstract:  A new species of the genus Epiphaxum (family Lithotelestidae) is described and illustrated in detail, and compared to other species. Epiphaxum arbuscula sp. nov. has been collected from Upper Eocene (Priabonian), Upper Oligocene (Chattian) and Lower Miocene (Upper Burdigalian) deposits of the Aquitaine Basin, south-west France. Epiphaxum is a poorly documented genus but its fossil record extends back to the Late Cretaceous; it was previously known only from the Paleocene (Danian). Epiphaxum arbuscula differs from all others species of the genus in the form of its colony. In contrast to the creeping colonies of previously known species, it has branched colonies. It is very common at one Upper Oligocene outcrop from which an assemblage with submarine cave remains has been described. A close relationship between the three extant species (two from the Caribbean Sea and one from the Indo-West Pacific region) and the Paleogene species is also noted. These constitute a group that has not undergone any important morphological changes for the last 65 million years.

THE TAXONOMIC AND PHYLOGENETIC POSITION OF THE PLESIOSAUROIDEA FROM THE LOWER JURASSIC POSIDONIA SHALE OF SOUTH-WEST GERMANY

Abstract:  The two plesiosauroid species from the Posidonia shale of Holzmaden, ' Plesiosaurus ' guilelmiimperatoris and ' Plesiosaurus ' brachypterygius , do not belong to Plesiosaurus but form new monotypic genera. The new genus Hydrorion is erected for ' P .' brachypterygius , and the genus Seeleyosaurus is re-established for ' P .' guilelmiimperatoris . The recently described species Plesiopterys wildii is regarded as a junior synonym of S. guilelmiimperatoris . A short phylogenetic analysis shows that S. guilelmiimperatoris and Muraenosaurus are basal elasmosaurs. H. brachypterygius , Occitanosaurus tournemirensis from France and Microcleidus homalospondylus from England form a monophyletic clade, which is the sister taxon to the Cretaceous elasmosaurs. A palaeobiogeographical comparison of plesiosaur localities in the Lower Jurassic shows distinct palaeobiogeographical zones for the Toarcian, with different plesiosaur taxa in England, Germany and France.

SKULL MORPHOLOGY AND PHYLOGENETIC RELATIONSHIPS OF A NEW DIMINUTIVE BALAENID FROM THE LOWER PLIOCENE OF BELGIUM

Abstract:  A new small balaenid is described and compared to all fossil and living balaenid taxa. The specimen represents a new genus and species and is named Balaenella brachyrhynus . It was discovered in the Lower Pliocene of Kallo (north-west Antwerp, Belgium) and adds new information on the diversity and evolution of Balaenidae. Based on both comparative morphology and phylogenetic analysis, Balaenella brachyrhynus is morphologically closer to the genus Balaena , including the living Greenland Bowhead whale ( B. mysticetus ), and two Pliocene species ( B. montalionis and B. ricei ) from central Italy and the eastern USA. Balaenella brachyrhynus has very short nasals, a short rostrum relative to the total skull length and a horizontal supraoccipital. A cladistic treatment of 81 morphological character states scored for 10 balaenids and nine non-balaenid cetaceans revealed that the other small balaenids generally included in the genus Balaenula (including Balaenula astensis, B. balaenopsis and a Pliocene Balaenula sp. from Japan) are closer to the living genus Eubalaena (the Right whale). As the new skull is so different from the nominal Balaenula species, and as it is more closely related to Balaena than to Eubalaena , it is concluded that a small body size was a common condition in different Balaenidae clades.     

中国新纪录种长须拟鳠记述及拟鳠属评述(英文)

记述采自中国广西壮族自治区的北伦河鲿科鱼类1新纪录种,长须拟鳠Mystus gulio(Hamilton,1822)。新纪录种为1小型鲿科鱼类,其主要形态特征如下:背鳍Ⅱ,7;胸鳍Ⅰ,8;腹鳍条11～13;脊椎骨数29～31;胸鳍和背鳍棘后缘呈锯齿状;脂鳍基长不及臀鳍基之半长;眼睛圆形且中等大;尾鳍深叉状,上叶稍长于下叶;上颌须末端达腹鳍基中部。拟鳠属Mystus与其近缘属拟鳠Hemibagrus种类的眼前缘与后鼻孔的距离明显大于两鼻孔间距,为这两属区别于鲿科其他属的形态特征之一。鳠属种类的脂鳍基都较长,一般为臀鳍基的2倍; 拟鳠属种类的指鳍基长度变化较大,或大于臀鳍基长,或短于臀鳍基长; 脂鳍基长度不宜用于鉴别拟鳠属和鳠属。但两属的枕骨和囟门沟的形态差异显著,拟鳠属种类的枕骨宽大,囟门沟短;鳠属种类的枕骨窄小,囟门沟长;该类特征可用于鉴别两属物种。

A revision of the species of <Emphasis Type="Italic">Saturnius</Emphasis> Manter, 1969 (Digenea: Hemiuridae), parasites of mullets (Teleostei: Mugilidae)

The genus Saturnius Manter, 1969 is defined, its species re-examined and a key to the species presented. S. overstreeti n. sp. is described from Mugil soiuy Basilewsky and M. cephalus L. from the Russian coast of the Sea of Japan and distinguished from the morphologically related S. papernai Overstreet, 1977 and S. maurepasi Overstreet, 1977. S. segmentatus Manter, 1969 is redescribed on the basis of the type- and newly collected material from M. cephalus on the Russian coast of the Sea of Japan. The morphometric variation of S. papernai is studied based on newly collected material from Liza aurata (Risso) in the Ebro Delta and off Santa Pola, Spain. The comparisons reveal lower ranges of most metrical features than previously known. A principal component analysis, carried out after adding the new data to those of Blasco-Costa et al. (2006), confirms the species identification. Other valid species recognised are S. mugilis (Yamaguti, 1970), S. maurepasi, S. belizensis Fischthal, 1977, S. dimitrovi Blasco-Costa et al., 2006 and S. minutus Blasco-Costa et al., 2006. Forms considered species inquirendae are S. valamugilis Rekharani & Madhavi, 1984, Bunocotyle constrictus Domnich & Sarabeev, 1999 [=S. papernai of Domnich & Sarabeev (2000a, b, c, d)], B. mugilis Yamaguti, 1970 of Solonchenko (1976) and S. mugilis of Dmitrieva & Gaevskaya (2001). Host and locality information is given in detail for all species. Lisa ramado (Risso) and Chelon labrosus (Cuvier) are new host records for S. papernai (sensu stricto) and S. dimitrovi. L. aurata is a new host record for S. dimitrovi and S. minutus, and L. saliens (Risso) is a new host record for S. minutus.
