A summary is presented of all Peruvian species of scaly tree ferns (Cyatheaceae). A total of 83 species is native to Peru (Sphaeropteris 1 sp., Alsophila sect. Alsophila 9 spp., Alsophila sect. Gymnosphaera 1 sp., Cyathea 72 spp.), with 13 endemic species in Cyathea and one in Alsophila. The following new species are described and illustrated: Alsophila gastonyi, Cyathea chontilla, C. nephele, C. polliculi, and C. praetermissa. The genera Cnemidaria and Trichipteris are no longer recognized and merged in Cyathea. Necessary combinations are made for Cyathea alatissima, C. nervosa, and C. uleana. Cyathea serpens is presented in detail and its relationship is discussed. An artificial key to the Peruvian species of Cyatheaceae is provided.  相似文献

The Malagasy fauna includes two genera of Philopotaminae: Wormaldia McLachlan 1865 and an endemic new genus, Ranarijaodes n. gen. The Malagasy and African (sensu stricto) lineages of Wormaldia are distinct. Apomorphic characters (the shape of the phallic apparatus for the African species and the splitting of the median lobe of the tenth tergite for the Malagasy species) confirm their separation. New captures are reported for two of the four previously known species of Wormaldia. Seven new species are described: Wormaldia ambahibeae n. sp., W. faharoa n. sp., W. fahatelo n. sp., W. randriamasimananai n. sp., W. fahefatra n. sp., W. legrandi n. sp. and W. fahadimy n. sp. Ranarijaodes n. gen. is close to Dolophilodes Ulmer 1909. It is described for the three new species Ranarijaodes fiana n. sp., R. angapi n. sp. and R. atsimo n. sp. The 14 Malagasy species of Philopotaminae are endemics of the island. Their geographical distributions and ecological preferences are described and discussed.  相似文献

( ± )-Methyl phaseates were synthesized from ( ± )-4-(6′-acetoxymethyl-2 ′,6′-dimethyl-1′-cyclohexen-1′-y1)-but-3-en-2-one (20), which was prepared from a useful terpenoid building block, ( ± )-2-hydroxymethyl-2,6-dimethyl-1-cyclohexanone (11a and 11b). Photooxidation of the cyclohexadiene intermediate (22), followed by alkaline hydrolysis and methylation, gave four stereoisomers of ( ± )-methyl phaseates: (2Z,4E)-cis form (2), (2E,4E)-cis form (24), (2Z,4E)-trans form (25) and (2E,4E)-trans form (26).  相似文献

The following new species of Apioninae weevils (Coleoptera: Brentidae) are described from Dominican amber. Toxorhynchus leptorhinusn. sp., Toxorhynchus robustusn. sp., Toxorhynchus amphioculusn. sp., Toxorhynchus atriartusn. sp., Toxorhynchusatriantenusn. sp. and Toxorhynchus hispaniolicusn. sp. are members of the Toxorhynchus decoloratum species group. Toxorhynchus microsomusn. sp., Toxorhynchus stenelytrusn. sp., Toxorhynchus dominicanusn. sp., Toxorhynchus convexusn. sp., Toxorhynchus fuscocorpusn. sp., Toxorhynchus hispidulusn. sp. and Toxorhynchus convexoculusn. sp. are members of the Toxorhynchus sordidum species group. A new subtribe, Stenapiina n. subtribe of the tribe Toxorhynchini, is erected. New species Apionion homochrononn. sp.,Apionion kallimosumn. sp.,Apionion formoculusn. sp. and Stenapion levigatumn. sp. are described. The dominate species of the genus Toxorhynchus and especially those in the Toxorhynchus decoloratum and Toxorhynchus sordidum species groups in Dominican amber are now absent from the West Indies. A systematic update of extant representatives of Apioninae in Hispaniola is provided.http://www.zoobank.org/urn:lsid:zoobank.org:pub:2D4A59DB-E804-4B45-8773-C027A8AD5A02  相似文献

Background: It is argued that coastal endemic taxa may evolve in parallel at the periphery of the distributional range of a widespread species.

Aims: We tested this hypothesis for the origins of three peripheral, coastal isolates of Senecio, S. glaucus ssp. glaucus (Israel), S. g. ssp. coronopifolius p.p. (Sicily), and S. hesperidium (Morocco), from widespread S. glaucus ssp. coronopifolius. We also determined the relative roles of selection vs. genetic drift in shaping phenotypic divergence in ssp. glaucus and S. hesperidium, using Lande’s test of neutral morphological change.

Methods: We surveyed morphological and/or allozyme variation in the three peripheral isolates and mainly inland populations of S. g. ssp. coronopifolius.

Results: Genetic data supported independent origins of the coastal taxa from nearby populations of ssp. coronopifolius. These descendant and ancestral populations showed pronounced morphological but weak genetic differentiation. Phenotypic similarities between ssp. glaucus (Israel) and S. hesperidium (Morocco) in plant height and floral traits may have resulted from parallel divergent selection from ssp. coronopifolius, though drift remains an alternative cause in S. hesperidium.

Conclusions: Our results indicate parallel ecotype formation and (sub)speciation in Senecio in which primarily selective vs. neutral determinants promoted the recurrent origin of coastal types in, respectively, Israel and Morocco.  相似文献

A series of new N′-[N-(2,3,4-tri-O-acetyl-β-d-xylopyranosyl)thiocarbamoyl]-2-[(1-aryl-1H-tetrazol-5-yl)sulfanyl]acetohydrazides 5a5e were synthesized rapidly in high yields from 2-(1-aryl-1H-tetrazol-5-ylsulfanyl)acetohydrazides 3a3e and 2,3,4-tri-O-acetyl-β-d-xylopyranosyl isothiocyanate 4, then 5a5e were converted to a series of new 5-(1-aryl-1H-tetrazol-5-ylsulfanylmethyl)-N-(2,3,4-tri-O-acetyl-β-d-xylopyranosyl)-1,3,4-oxadiazole-2-amines 6a6e and 5-(1-aryl-1H-tetrazol-5-ylsulfanylmethyl)-N-(2,3,4-tri-O-acetyl-β-d-xylopyranosyl)-1,3,4-thiadiazole-2-amines 7a7e, respectively under mercuric acetate/alcohol system or acetic anhydride/phosphoric acid system, then deacetylated in the solution of CH3ONa/CH3OH. All of the novel compounds were characterized by IR, 1H NMR, 13C NMR, MS and elemental analysis. The structures of compounds 2e, 3e, 5a and 5c have been determined by X-ray diffraction analysis. Some of the synthesized compounds displayed PTP1B inhibition and microorganism inhibition.  相似文献

This paper reports on a total synthesis of racemic δ-cadinene (2), which had been obtained previously in optically active form by acid-catalyzed cyclization of (–)-germacrene D. The Robinson annelation using cyclohexenone enamine (12) proceeded stereoselectively to form δ-cadinenone (3), whose oxygen was removed by the thioketal–Raney Ni method to produce δ-cadinene.  相似文献
