Five new species of Triotemnus (Coleoptera, Curculionidae, Scolytinae) from Morocco and Yemen

Fivenew species of the genus Triotemnus from Morocco and Yemen are described. Triotemnus is a new genus of Scolytinae for the Yemen region. External morphology of the new species and all morphologically related species of the genus were studied. While the new species from Morocco are morphologically similar to the known species from the corresponding region, all three newly described species from Yemen, mainly two of them living in Socotra, are morphologically very different from all other known species of the genus. Geographical distribution and the probability of endemicity are discussed.     

中国杭子梢属植物的研究

本文叙述了杭子梢属(gen.Campylotropis)植物的研究历史,说明在中国一共记录过59种杭子梢属植物,经过著者的研究整理,确定并提出了14种新的异名名称,经过详细考订,本属植物在中国已确知为29种、6变种、6变型。其中包括经发现和研究整理的新种4、新变种3、新变型3、新组合变种2、新组合变型3。此外尚有2个存疑种有待今后采集调查解决。本文历述了关于本属是否应该并入胡枝子属(gen.Lespedeza)这一问题所存在的长期争议之后,详细论述了本属与胡枝子属在特征上的异同诸点、进行了比较和分析,据此,明确地肯定本属与胡枝子属亲缘关系极为相近,但特征的分化已经必须确认本属应是与胡枝子属有明确区别的独立的属。此外,从特征分析中也可得出本属应是由胡枝子属大胡枝子组(sect.Macrolespedeza)演化发展而来的。本文在讨论了属内主要特征的演化趋势与种群关系之后,论述了本属在世界主要分布地区的种数和分布概况,同时将此与胡枝子属大胡枝子组的分布概况作了比较和分析,明确地认定我国机子梢属植物的大部分种类是本国西南地区发生的(中国有20个特有种),我国的西南地区是本属植物的分布中心,也是本属植物从较原始特征开始分化的一个特征分化多样化中心,并且此地区正是胡枝子属大胡枝子组与本属多数种类包括较原始种类分布相交叉的地区,因而我国的西南地区有可能即是本属植物的起源中心,并且这一起源应是与胡枝子属大胡枝子组植物分布到中国西南地区以后的分化发展想联系的。

中国酣弄蝶属名录与一新种记述(鳞翅目,弄蝶科)

酣弄蝶属Halpe全世界已知48种,中国已知16种,在总结中国酣弄蝶分类研究的基础上,记述1新种：凹斑酣弄蝶Halpe concavimarginata sp.nov.,制作了中国酣弄蝶属分种检索表。模式标本保存于西北农林科技大学昆虫博物馆。 凹斑酣弄蝶,新种Halpe concavimarginata sp.nov.（图1 ～5） 新种外形与峨眉酣弄蝶Halpe nephele Leech,1893非常近似,主要区别是：新种前翅长18～20mm;前翅中域斑的外缘向内凹入;前后翅的缘毛黑白相间非常明显;抱器端2分瓣间的“U”形凹陷跨度较小,凹陷底部无锯齿。峨眉酣弄蝶Halpe nephele Leech前翅长17.5～18.0mm;前翅中域斑的外缘直,不凹入;前后翅的缘毛黑白相间不明显;抱器端两分瓣间“U”形凹陷跨度大,锯齿连续。 新种也近似白缘毛酣弄蝶Halpe albicilia Tsukiyama et Chiba,1991 ,区别在于白缘毛酣弄蝶前翅长21mm,后翅的缘毛全白色,外生殖器也不同。 模式标本正模♂,副模1 ♂,四川芦山, 1996 ,汪炳红采。     

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.     

Revision of the genus Phloeoditica Schedl - with description of two new genera and two new species in Phloeosinini (Coleoptera, Curculionidae, Scolytinae)

The genus Phloeoditica Schedl currently includes four species from Southeast Asia. These species vary substantially in important morphological characters and indicate the existence of multiple genera for these species. A revision based on morphological and in part molecular data resulted in the transfer of Phloeoditica setosa to Pseudoxylechinus the erection of a new genus Asiophilus for Phloeoditica phloeosinoides and a new species Asiophilus macropunctatus from Vietnam. Another new genus with affinities to Phloeoditica is described based on the new species Microditica uniseriata from Thailand. The new genera are included in a revised key to the tribe Phloeosinini.

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)     

中国木兰科11属40种植物的核形态研究

为了探讨木兰科属间系统学关系和一些种的分类学地位,对中国木兰科11属40种进行了核形态研究。所研究的20种木莲属植物都为二倍体,表明木莲属植物主要是在二倍体水平上进化的,不同的种类具有各自的遗传组成,细微的染色体结构变异可能导致种间形态发生了明显的变化。木兰属的染色体数目具多样性,表明属内存在着不同倍性水平上的进化,说明木兰属分布广泛、形态复杂多样有其细胞学基础。细胞学证据支持木莲属应为独立的属,不宜于归并到木兰属。已观察的含笑属都为二倍体,而木兰属玉兰亚属的大多数种类为多倍体。我们认为维持现有的含笑属的分类地位和范围是恰当的,不支持将含笑属和玉兰亚属合并为一属。拟单性木兰属都是多倍体。木兰科植物形态特征重叠,性状呈网状进化,细胞学证据在探讨一些大属属下种的分类地位时具有一定价值,但论及整个科的分类系统和属间亲缘关系时,作用比较微弱。本文在细胞学基础上,结合形态和地理分布,重点对木莲属一些种类的分类地位进行了讨论。     

A new species of Acanthostigma (Tubeufiaceae, Dothideomycetes) from the southern hemisphere

A new species belonging to the Dothideomycete genus Acanthostigma is described from bark of two Nothofagus species from Argentina. Its identity as a new species is based on both morphology and molecular sequence data. Acanthostigma patagonica differs from other species in the genus by having larger ascomata and setae and wider, asymmetrical ascospores. An amended key to Acanthostigma species is provided along with a discussion of other species previously described from South America.     

A new species of Parapygmephorus Cross, 1965 (Acari; Heterostigmatina; Neopygmephoridae) phoretic on Halictus quadricinctus (Fabricius, 1776) (Hym.; Halictidae) from Iran

A new species of the genus Parapygmephorus Cross, 1965 (Acari: Heterostigmatina, Neopygmephoridae) is described from Northeastern Iran. A phoretic adult female of Parapygmephorus khorasanicus Hajiqanbar and Khaustov sp. n. was discovered clasping on hairs on the ventral body surface of Halictus quadricinctus (Fabricius, 1776) (Hymenoptera; Halictidae). It is the fifth representative among the known species of the genus Parapygmephorus in the world. Differentiation of new species from other species of the genus is discussed, and a key to known world species is provided.     

The phylogeny of Halgerda (Opisthobranchia, Nudibranchia) with the description of a new species from Okinawa

This paper proposes a refined hypothesis of evolution for the tropical Indo-Pacific nudibranch genus Halgerda . Numerous specimens from 31 species were examined anatomically and literature from four additional species was reviewed, bringing to 33 the ingroup taxa. Fifty-three characters were considered from these examinations. The outgroup Asteronotus was used to polarize the characters. The phylogeny obtained from the analysis of the characters supports the hypothesis that Halgerda is a monophyletic group. A species previously placed with the genus Sclerodoris is examined and determined to be a member of the genus Halgerda . Phylogenetic analysis places this species, H. paliensis , as a basal member of the genus . Halgerda paliensis appears to be restricted to the Hawaiian Islands. Specimens previously identified as Sclerodoris paliensis from the Marshall Islands actually represent H. dalanghita Fahey & Gosliner, 1999. A new species, Halgerda onna , is described and presented as the sister taxon to a basal member of the genus. A range and depth extension of a previously described species, H. malesso , is presented. The present phylogeny is then compared to previous studies, in particular those of Fahey & Gosliner (1999a,b) .
