| La aracnofauna chilena ha sido parcialmente estudiada a través de los años, pero no en forma continua, lo que ha determinado un escaso conocimiento de los taxones presentes en nuestro país. La ausencia de textos y manuales que faciliten la identificación, y determinación taxonómica de las arañas presentes en Chile, hace aún más difícil el estudio de este grupo. Para Chile se han descrito 55 familias, de las cuales 6 pertenecen a Mygalomorphae y 49 a Araneomorphae, lo que representa aproximadamente el 50% de las familias conocidas a nivel mundial. En este estudio se reconocen 51 familias. Es importante destacar la necesidad de continuar con estudios sistemáticos de las arañas presentes en Chile, y determinar su biología, distribución geográfica y... |

| The number and identity of the species of black widow spiders of the genus Latrodectus that inhabit Chile remain unclear. Here we present results of taxonomic work based on morphologic and molecular characters of a large series of specimens collected throughout Chile, which aimed to assess Chilean Latrodectus diversity. Results show that all studied populations belong to a single species, for which the correct name is Latrodectus thoracicus Nicolet 1849. Therefore, we remove this taxon from the synonymy of L. mactans (Fabricius, 1775). In addition, we suggest that L. mirabilis (Holmberg, 1876) may be junior synonym of L. thoracicus. We recognize two species of black widows for continental Chile, L. thoracicus andi. variegatus Nicolet, 1849. We provided an... |

| Components of essential oils from the Chilean Monimiaceae, boldo (Peumus boldus Mol.), tepa (Laureliopsis philippiana (Looser) Schodde), and laurel (Laurelia sempervirens (Ruiz & Pav.) Tul.) were determined using Gas Chromatography- Mass Spectrometry (GCMS) and fungistatic activity of the essential oils was tested against Rhizoctonia solani Kühn (Donk), Pythium irregulare Buisman, Ceratocystis pilifera (Fr.) C. Moreau, Phragmidium violaceum (Schultz) G. Winter, and Fusarium oxysporum Schltdl. The essential oils of the Monimiaceae species shared some common components; all three had the 3-carene, α-phellandrene, and α-pinene terpenes. L. philippiana and L. sempervirens also had safrole.The main components were ascaridol in P.... |
