Three New Species

We revise the Australian Phytoseiinae (Acari : Mesostigmata : Phytoseiidae) based on a study of over 1000 slide-mounted specimens. Of the three currently recognised genera in the subfamily, onlyPhytoseius is known from Australia, but endemic species occur in each of its three species-groups. We describe 11 new species, including P. bunya, the first Australian representative of the purseglovei-group. The plumifer-group is represented by five species including P. danutae, sp. nov. and P. improcerus Corpuz, a Philippine mite newly reported from Australia; in addition, P. leaki Schicha is newly reported from New Zealand. In Australia, the horridus-group contains two oceanic-island species, P. hawaiiensis Prasad and P. mayottae Schicha (newly reported), and two complexes of Australasian endemics. The fotheringhamiae-complex has seven species, including three new species from tropical rainforests in far north Queensland – P. paluma,P. camelot and P. devildevil; in addition, P. fotheringhamiae is newly reported from New Zealand. The douglasensis-complex also has seven species, including six new species from Queensland and the Northern Territory: P. oreillyi, P. acaciae, P. brigalow, P. mantoni, P. darwin and P. litchfieldensis. All 22 species of Phytoseiusknown from Australia are keyed and diagnosed, and their distributions are detailed.

Abstract The endemic dove Zenaida graysoni of Socorro Island, an oceanic island in the Pacific south of Baja California, became extirpated between 1958 and 1978, and the endemic mockingbird Mimodes graysoni diminished during the same years and was approaching extinction by 1981. The mainland Mourning Dove Z. macroura became established on Socorro between (probably) 1971 and 1978, and the mainland Northern Mockingbird Mimus polyglottos between 1978 and 1981. Superficially an instance of replacement of island endemics by mainland relatives through competitive exclusion, the case is actually more complicated. We argue that extermination of the endemics was probably caused by predation by feral cats introduced in 1957 or later. There is no evidence of any actual competition between the pairs of species, and their preferred habitats overlap only slightly. We attribute the nearly concurrent establishment of the two invading species, known to have occurred frequently as casual visitors to Socorro and other islands, largely to the provision of fresh water made available as a result of human settlement. Our data show that simple comparison of island species lists compiled at intervals is an inadequate base for theories of island species turnover.

Asian Clade

The polyphyly of the pantropical genus Schefflera J. R. Forst. & G. Forst. (Araliaceae) is now well established, and consequently the genus has had to be restricted to its type (S. digitata J. R. Forst. & G. Forst.) and seven closely related Pacific Island species. Taxonomic transfers of the members of four other, unrelated clades have mostly been completed, including those from Africa and Madagascar, the Neotropics, and Oceania. Here we treat the final and largest group, from Asia, reinstating the genus Heptapleurum Gaertn. for the 317 species that belong to the Asian clade of Schefflera. This synopsis provides 256 new combinations for 246 species and 10 varieties, along with one replacement name, and types are designated for five generic and infrageneric names. With the completion of these transfers, Heptapleurum is now the largest genus in Araliaceae.
