A review of the Banchus-group of ichneumon-flies, with a revision of the Australian genus Philogalleria (Hymenoptera: Ichneumonidae)

ABSTRACT. The composition and relationships of the Banchus genus-group are discussed. A key to the genera is provided and for each genus a diagnosis and notes are given. A new genus and species are described. The genus Philogalleria Cameron is revised: six species (five of them new) are recognized, described and keyed. Rhynchobanchus is newly recorded from Britain and a key is given to its European species.     

The genus Iphionopsis (Compositae - Inuleae)

The new genus Iphionopsis A . Anderb. (Compositae-Inuleae-Inulinae) is described with its two species, transferred from the genus Iphiona Cass., I. rotundifolia (Oliv. & Hiern) A. Anderb. from Ethiopia, Somalia, and Kenya, and I. ilicifolia (Humbert) A. Anderb. from Madagascar. The genus is monophyletic, defined by a number of synapomorphies.     

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.

六种鼠乳酸脱氢酶和超氧化物歧化酶位点变异的研究

用电泳比较分析了鼠科动物６个种的组织ＬＤＨ同工酶的Ａ、Ｂ、Ｃ亚基和ＳＯＤ同工酶位点的种属差异。结果表明,ＬＤＨ的Ａ和Ｂ亚基在进化上的可变性程度不同。在被分析的２个属共６种鼠中,首次发现Ｂ亚基的结构具有属的特征,同属的鼠种Ｂ亚基泳动度相同,在垂直凝胶电泳板上处于同一泳动线上。不同属的鼠其Ｂ亚基泳动度不同,家鼠属的鼠Ｂ亚基比姬鼠属的泳动快;Ａ亚基的结构既有属的特性,更具有种的特征,同属不同种的鼠Ａ亚基泳动速度不同,表现为ＬＤＨ同工酶带的间距不同。ＬＤＨ的Ｃ亚基结构因鼠种不同而异,由Ｃ亚基组成的ＬＤＨ－Ｘ带黄毛鼠位于自身的ＬＤＨ－３和ＬＤＨ－４之间,社鼠和褐家鼠此带位于自身的ＬＤＨ－４和ＬＤＨ－５之间,白腹巨鼠此带位于自身的ＬＤＨ－５以外的阴极端,与黑线姬鼠此带的位置特征相同。ＳＯＤ同工酶带只表现种的差异,其３条带泳动速度的改变具有协同而变的共同特点。被分析的鼠种经配对法比较生化特征的相同程度,初步表明黄毛鼠亲缘上与褐家鼠比较近,白腹巨鼠亲缘上又比其余３种鼠更近于姬鼠属。     

On two nematodes from Brazilian birds and description of a new species (Acuarioidea, Schistorophinae) parasitizing Laterallus viridis (Müller, 1776) (Gruiformes, Rallidae)

The present paper reports acuarioid nematodes recovered from avian hosts. A new species of the genus Schistorophus Railliet, 1916 is proposed based mainly on findings referring to ptilina, spicules and vagina. Ancyracanthopsis coronata (Molin, 1860) Chabaud & Petter, 1959 is referred again in Brazil since its proposition in 1860, from specimens recovered from a Brazilian bird. A revised key to the species of the genus Schistorophus is also presented.     

Taxonomic review of the genus Macrosiphum (Sternorrhyncha: Aphididae) for the Korean Peninsula, with description of a new species

Eight species of the genus Macrosiphum Passerini 1860 (Sternorrhyncha: Aphididae) are recognized from the Korean Peninsula. A new species, Macrosiphum ( Macrosiphum ) paektusani n. sp., is described herein for apterous and alate viviparous females on Rosa marretii Lev. (Rosaceae). The taxonomic position of Macrosiphum ( Macrosiphum ) cornifoliae Shinji 1924, com. rev., is transferred from the genus Sitobion Mordvilko 1914 to its original position. Host plants of the Korean Macrosiphum are reviewed and the identification key to subgenera and species is also presented.     

Mariapanteles (Hymenoptera, Braconidae), a new genus of Neotropical microgastrine parasitoid wasp discovered through biodiversity inventory

A new genus of microgastrine parasitoid wasps, Mariapanteles Whitfield & Fernández-Triana, gen. n., is described from rain forests of the Neotropics. The new genus is related to the common and speciose genus Pseudapanteles, but can be distinguished from the latter by having a complete transverse carina on the propodeum which forks around the spiracles. A molecular analysis based on data from COI from specimens of the proposed new genus plus possibly related genera confirms its generic distinctness. A key to two known species, Mariapanteles felipei Whitfield, sp. n. (Costa Rica) and Mariapanteles dapkeyae Fernández-Triana, sp. n. (Brazil) is provided. Evidence from collections suggests that there are other undescribed Neotropical congenerics. Specimens of Mariapanteles were likely confused in the past with the genus Beyarslania (referred to as Xenogaster until recently) but present information suggests that Beyarslania is restricted to the Afrotropical region while the Neotropical species clearly belong to a different genus, which we propose as new.     

Araucnephia iberaensis n. sp., a neotropical black fly with a peculiar distribution (Diptera-Simuliidae)

Araucnephia Wygodzinsky & Coscarón is a Neotropical black fly genus in which only one species from Central Chile is known. Another species has now been found in Corrientes province on the eastern side of the Iberá tropical swamps of Argentina, on the western border of the mountainous region of southern Brazil. This new species, A. iberaensis, is herein described and illustrated and information on its bionomics is recorded. It is an interesting species because previous to its discovery no black fly genus or subgenus from Central Chile region has been found in tropical areas, because these two regions are separated by the Monte and Pampas realms. Similarly, no Brazilian genus or subgenus has crossed the Andes mountains to Chile. A comparison with other Neotropical, Nearctic, Ethiopian (Afrotropical) and Australian Prosimuliini (sensu Crosskey & Howard) showed Araucnephia to be a valid taxon most closely related to Araucnephioides (sympatric in Chile). Araucnephia also shows great affinities with Lutzsimulium from Southeast Brazil and Argentina and Paracnephia from South Africa.     

多倍化——白刺属的系统分类、进化特征及应用前景

在回顾白刺属研究历史的基础上,根据白刺属种间染色体倍数特征并结合形态学、生物地理学等方面的研究文献,提出新的白刺属种间分类系统：二倍体组(2n= 2X=24) 和四倍体组 (2n=4X=48)。多倍化(2X→4X)是白刺属内种间进化的基本特征。白刺属的起源中心可能是古地中海沿岸地区;中亚及我国西北地区是白刺属的现代分布中心。并指出将该属作为模式系统开展荒漠植物分子生态学研究的前景。     

Helminths in Mesaspis monticola (Squamata: Anguidae) from Costa Rica, with the description of a new species of Entomelas (Nematoda: Rhabdiasidae) and a new species of Skrjabinodon (Nematoda: Pharyngodonidae)

Entomelas duellmani n. sp. (Rhabditida: Rhabdiasidae) from the lungs and Skrjabinodon cortagoensis n. sp. (Oxyurida: Pharyngodonidae) from the intestines of Mesaspis monticola (Sauria: Anguidae) are described and illustrated. E. duellmani is the sixth species assigned to the genus and is the third species described from the Western Hemisphere. It is easily separated from other neotropical species in the genus by pre-equatorial position of its vulva. Skrjabinodon cartagoensis is the 24th species assigned to the genus and differs from other neotropical species in the genus by female tail morphology.     

A new genus of soft coral of the family Alcyoniidae (Cnidaria, Octocorallia) with re-description of a new combination and description of a new species

A new genus, Aldersladum (family Alcyoniidae), is established to accommodate a previously described species, Efflatounaria sodwanae Benayahu, 1993 (family Xeniidae) from Sodwana Bay, South Africa that was wrongly assigned to the latter genus. This species is redescribed and a second new species, Aldersladum jengi from Penghu Is., Taiwan, is described. The diagnostic features of the new genus include the presence of only figure-eight shaped platelets in all parts of the colony, thus differentiating it from all known genera of the Alcyoniidae. Based on examination of additional material from other localities, the zoogeographical distribution of the genus is confirmed to include the coral reefs of South Africa, Kenya, Gulf of Oman, Taiwan and Japan. Phylogenetic analyses of two mitochondrial genes strongly support its placement in the family Alcyoniidae.     

A new Australian genus of Araceae, with notes on generic limits and biogeography of the Areae

HAY, A., 1992. A new Australian genus of Araceae, with notes on generic limits and biogeography of the Areae . A monotypic aroid genus is described from Melville Island, Northern Territory, Australia. The genus is diagnosed in the tribe Areae by its tubular spathe base divided into two chambers by an annular septum. The genus is most closely related to Sauromatum and to some Asiatic, not Australian, species of Typhonium . It is proposed that the geography of the Areae (including Arum, Dracunculus etc.) may now suggest a Gondwanan (rather than Laurasian) and hence Cretaceous (rather than much more recent) origin for the tribe, and its dual arrival in Malesia.     

Biodiversity of Asterina species on Neotropical host plants: new species and records from Panama

Two new species of the genus Asterina are described from living leaves collected in provinces Chiriquí and Bocas del Toro in western Panama. Asterina alloplecti on Alloplectus ichtyoderma (Gesneriaceae) differs from other Asterina on Gesneriaceae by its stalked appressoria and host relationship. Asterina compsoneurae on Compsoneura sprucei (Myristicaceae) can be distinguished from other members of Asterina on Myristicaceae by its larger ascomata, larger, prominently spinose ascospores and host relationship. New records for Panama are Asterina corallopoda from a new host plant species (Solanum trizygum, Solanaceae), A. diplopoda, A. ekmanii from a new host plant species (Gonzalagunia rudis, Rubiaceae), A. siphocampyli from a new host plant genus and species (Burmeistera vulgaris, Campanulaceae) and A. styracina from a new host-plant species (Styrax argenteus, Styracaceae). This study increases the number of species of Asterina known for Panama from 12 to 19 and the number of Asterinaceae from 14 to 21. Asterina corallopoda, A. diplopoda, A. ekmanii, A. siphocampyli and A. styracina are illustrated for the first time. A phylogeny inferred from the analysis of LSU rDNA sequences of species of Asterina is presented. The diversity and host-plant patterns of known Neotropical species of Asterina are discussed.     

A new species of Brachygasterina Macquart from Chile (Diptera: Muscidae)

The genus Brachygasterina Macquart is Neotropical, with six species recorded from Argentina, Chile, Ecuador and Colombia. A new species was found among an extensive unidentified muscid material from South America in the collection of the California Academy of Sciences collection (San Francisco, California, U.S.A.). Brachygasterina maculata, new species, from Santiago, Chile, is here described and illustrated, and its position in the genus Brachygasterina is discussed.     

A Study on Dichocarpum (Ranunculaceae)

The genus Dichocarpum was established by W. T. Wang and Hsiao in 1964, who divided the genus into 2 sections: Sect. Dichocarpum including 10 species distributed on the mainland of E. Asia, and Sect. Hutchinsonia including 9 species native to Japan. M. Tamura and L. A. Lauener made a revision of the genus in 1968, who divided the genus into 4 sections, three for the species of the mainland of E. Asia, including 3 series and 10 species, and the other for the species of Japan, including 2 subsections, 3 series and 9 species. In the present paper, the genus is divided into 2 sections and 6 series, including 15 species and 3 varieties, and a putative phylogeny of the genus is proposed. The genus may be close to the genus Asteropyrum, and these two genera are rather specialized in Thalictroides (Ranunculaceae), because they have three very similar characters: the petal with a long claw, the stephanocolpate pollen and the chromosome morphology. The genus has 2n=24, 35(36?), which indicates that its basic number is X=6, and the species on the mainland of E. Asia (Sect. Dichocarpum) may well be paleotetraploids, whereas those in Japan (sect. Hutchinsonia) are paleohexaploids. Most of the advanced species are distributed in Japan and the most primitive ones in China and the Himalayas, the distribution pattern seggests that the Japanese members of this genus might have immigrated from China in the Tertiary, and differentiated and evolved there. The putative phylogeny of the genus is shown in Fig. 2 (at series level)
