A series of 40 male and 40 female mites of the prostigmatid genus Eupodes from the maritime Antarctic were each scored for 58 morphological characters, and principal co-ordinate analyses were performed on each data set. The analyses produced three clusters of points, which were interpreted as representing three species. One of these species, identified as Eupodes minutus (Strandtmann), the only species of Eupodes currently known from the maritime Antarctic, is redescribed. The other two species, E. exiguus up. and E. parvus nsp., are described. Two subspecies are recognized for the latter species, E. p. parvus from the South Orkney Islands, and E. p. grahamensis nsp. from the Antarctic Peninsula and South Shetland Islands. The geographical distribution and habitat preferences of the four text are discussed, and a key to the species is presented.  相似文献

Abstract. The twenty-four species of Pronophilini known from the Sierra Nevada de Santa Marta, a small, isolated and very high north Colombian mountain range, are listed. The ecology of the tribe in northern South America, where these butterflies are exclusively montane, is described. The evolutionary relationships of the thirteen endemic species are analysed. Three new genera, three new species, and four new subspecies are described. Four new synonymies are established, the status of three taxa revised, six new combinations made, lished, the status of three taxa and one original combination re-instated.  相似文献

A new species of the genus Cryptococcus, Cr. mycelialis (the type strain VKM Y-2863), is described based on the taxonomic study of four strains isolated from the soil and plant samples collected on the South Georgia and East Falkland islands. This species differs from the known Cryptococcus species in its ability to form a true monokaryotic mycelium with pseudoclamp connections and haustoria. The species can be distinguished from the phylogenetically related and phenotypically similar species Holtermannia corniformis and Cr. nyarrowii by some assimilatory reactions, maximum growth temperature, and sensitivity to mycocins.  相似文献

ABSTRACT. The Anopheles marshallii group of mosquitoes consists of four chromosomally typed species of which three have already been described and named. The fourth chromosomal species, formally known as species E, is described here as Anopheles kosiensis from Kosi Bay, Zululand, South Africa. A photograph of the X chromosome is given. The taxonomic status of Anopheles pitchfordi , a synonym of marshallii , is discussed.  相似文献

The genus Lessonia Bory de Saint‐Vincent is distributed solely in the Southern Hemisphere, with four species found in South America and five in Australasia. Our goal was to determine the evolutionary relationships between the Lessonia species of the two disjunct areas and hypothesize dispersal patterns and timing of radiation. We combined mitochondria, plastid and nuclear markers in a comprehensive dataset from multiple individuals per known species. Furthermore, for some species we added samples from multiple populations to take account of their widespread distribution over known bioregions. In all analyses the Australasian Lessonia formed a monophyletic group and in most analyses the South American species form a paraphyletic grade. Delimitations of the accepted species are highly supported except for L. variegata J. Agardh and L. nigrescens Bory de Saint‐Vincent. We showed for the first time four lineages for the New Zealand endemic Lessonia variegata with an unexpected high level of genetic differentiation. Our analysis cannot resolve whether the dispersal of the common ancestor of this genus was from the Americas to Australasia or vice versa. Molecular clock analysis suggested that a sudden radiation took place in Australasia c. 3.5 Mya when almost all Australasian species diverged within a time frame of only 35 000 years.  相似文献

In theory, competition among species in a shared habitat results in niche separation. In the case of small recondite mammals such as shrews, little is known about their autecologies, leaving open questions regarding the degree to which closely related species co‐occur and how or whether ecological niches are partitioned. The extent to which species are able to coexist may depend on the degree to which they exploit different features of their habitat, which may in turn influence our ability to recognize them as species. We explored these issues in a biodiversity hotspot, by surveying shrew (genus Crocidura) diversity on the Indonesian island of Java. We sequenced portions of nine unlinked genes in 100–117 specimens of Javan shrews and incorporated homologous data from most known Crocidura species from other parts of island South‐East Asia. Current taxonomy recognizes four Crocidura species on Java, including two endemics. However, our phylogenetic, population genetic and species delimitation analyses identify five species on the island, and all are endemic to Java. While the individual ranges of these species may not overlap in their entirety, we found up to four species living syntopically and all five species co‐occurring on one mountain. Differences in species' body size, use of above ground‐level habitats by one species and habitat partitioning along ecological gradients may have facilitated species diversification and coexistence.  相似文献
