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.

Taxonomy of the Neotropical Genus Americabaetis,New Status (Insecta: Ephemeroptera: Baetidae)

Americabaetis (Insecta: Ephemeroptera: Baetidae), previously considered synonymous with Acerpenna, is reinstated and given generic rank. The genus differs from Acerpenna in lacking hindwings, gills on abdominal segment 1, and a conical process between the male genital forceps, and in possessing apically rounded gills on abdominal segment 7. The genus has a general Neotropical distribution with a northern limit in east-central Mexico. Five new species of Americabaetis are described from South America: A. alphus, new species, from Argentina, Bolivia, Brazil, Chile, and Paraguay; A. labiosus, new species, from Brazil, Paraguay, and Uruguay; A. longetron, new species, from Brazil, Paraguay, and Uruguay; A. maxifolium, new species, from Paraguay; and A. titthion, new species, from Brazil. Americabaetis boriquensis, new combination; A. intermedius, new combination; A. naranjoi, new combination; A. pleturus, new combination; and A. robacki, new combination, are reviewed.     

A new species of Spauligodon (Nematoda: Oxyuroidea: Pharyngodonidae) in Latastia longicaudata (Sauria: Lacertidae) from Kenya

A new species of Spauligodon , Spauligodon latasticola n. sp., from the intestines of Latastia longicaudata (Lacertidae) from Kenya is described and illustrated. Spauligodon latasticola represents the 47th species assigned to the genus and the 8th species from the Ethiopian region. The new species differs from all but 2 other species assigned to Spauligodon by the presence of a conically tapering tail in the female. The new species is separated from the 2 similar species, Spauligodon garciaprietoi and Spauligodon goldbergi, by the position of the vulva, which is anterior to the esophageal bulb in the new species, at the level of the esophageal bulb in S. goldbergi, and posterior to the esophageal bulb in S. garciaprietoi.     

Tripterygiid Fishes of New Caledonia, with Zoogeographical Remarks

The Tripterygiidae of New Caledonia are revised and their zoogeographical relationships discussed. A total of 27 species is recognized from the territory; three species are recorded from New Caledonia for the first time [Enneapterygius howensis Fricke, 1997; Enneapterygius rhabdotus Fricke, 1994; Helcogramma trigloides (Bleeker, 1858)]. From Grande Terre, 26 species are known, with four species recorded for the first time. Seven species occur at the Ile des Pins (all new records); from the Chesterfield Islands, six species of tripterygiid fishes have been recorded; and from the Loyalty Islands, 17 species are known, with three species recorded from the island group for the first time: 15 species from Ouvéa, 11 species from Lifou (eight new records) and five species from Maré (three new records).     

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.

鸟类宏观分类和区系地理学研究概述

依据Dickinson,E.C.,主编,2003年出版的"The Howard and Moore Complete Checklist of the Birds of the World"一书和2000～2008年的有关文献的记载,在1958～2008年的50年期间,全世界所描述发表鸟类的新种,计有171种.以每10年中所发表的新种数进行统计比较,以1997～2007年期间所发表的新种为最多;按发现新种所属目级分类阶元的统计比较,以雀形目发现的新种为最多;按地区进行统计比较,以南美洲发现的新种数为最多,非洲中南部地区和太平洋诸岛为次;在中国境内描记的新种有台湾短翅莺Bradypterus alishannensis、峨嵋柳莺Phylloscopus emeiensis、海南柳莺Phylloscopus hainanus、峨嵋鹟莺Seicercus omeiensis、淡尾鹟莺Seicercus soror、弄岗穗鹛Stachyris nonggangensis、四川旋木雀Certhia tianquanensis等7种,其中由中国鸟类学者描记的有四川旋木雀和弄岗穗鹛两种.这说明鸟类的宏观分类研究,时至今日仍有研究的必要和发展空间.种下分类,是探讨同一个物种,随着分布区域的扩大,自然地理环境条件的变化,而产生地区性分布种群的变异,以致新物种形成的途径,是宏观分类学研究一个物种的演化发展.所以是当今鸟类分类研究的热点之一.据统计,1958～2008年的50年间,新描述发表的亚种数,约为1 129亚种.繁殖区域分布较为广泛的种类,所描记的亚种较多.如岛鸫Turdus poliocephalus分化有51亚种之多.中国鸟类的分类与区系地理学研究,大致可分为起步时期(1949年以前)、新中国建立之后的考察及宏观分类研究的总结整理时期(1950～2005)和宏观与微观相结合的发展研究时期(1999年以后)等3个时期.郑作新所出版的<中国鸟类分布名录>和<中国鸟类区系纲要>等专著,是中国鸟类宏观分类和区系地理学研究较为翔实的阶段性总结,为进一步研究奠定了坚实的基础.     

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.
