Adelphocorisella Miyamoto and Yasunaga newly recorded from Australia, with the description of a new species (Heteroptera: Miridae: Mirinae)

Adelphocorisella australis sp. n. is described from north Queensland. This, the first representative of the genus known from Australia, is compared with the two previously described species, both from Japan.     

First record of the genus Adelphocorisella Miyamoto and Yasunaga (Hemiptera: Miridae) from Korea

Adelphocorisella lespedezae Miyamoto and Yasunaga, 1993 , which was previously known only from Japan, is reported from Korea for the first time and diagnosed. An image of its dorsal habitus as well as illustrations of the male genitalia are provided. The discovery of the mirid species also represents the first distributional record in Korea as well as the continental Palaearctic Region for the genus Adelphocorisella Miyamoto and Yasunaga, 1993 .     

后丽盲蝽属作为属级分类单元的DNA分子证据

用蛋白酶K消化法提取并正反链双向测得半翅目盲蝽科盲蝽族(Mirini)中后丽盲蝽属(Apolygus)和草盲蝽属(Lygus)9个种的线粒体DNA细胞色素b基因片段的序列,应用Mega计算该两个属7个种11个Cyt b 432 bp片段序列的碱基组成、核苷酸的种间变异率、所编码的144个氨基酸的变异率。其核苷酸变异率：后丽盲蝽属内小于0．02,草盲蝽属内小于0．08(个别种例外);两个属种类之间平均变异率都大于0．10,平均为0．15。氨基酸变异率：后丽盲蝽属内种间无变异,而草盲蝽属内只有L．gemellatus与其他种间有13个氨基酸变异,仅占9．03％;两属各种类间却存在8～11个氨基酸的变异。表明在分子水平上两属之间较之于属内种间具有明显的差异,支持将后丽盲蝽从亚属提升为属级分类单元的分类观点。     

Food of the opossum Trichosurus vulpecula (Kerr) in the Waiho Valley,South Westland

Abstract

Opossums liberated in the Westland National Park between 1924 and 1930 became established. Analysis of 12 months' faecal samples (1974-75) showed that in the Waiho Valley opossums strongly preferred six plant species, but also ate others. Leaves were the most important food, though fragments of fruit, seed, bark, petiole, and invertebrates were found in the faeces. The preferred species included Metrosideros umbellata and Fuchsia excorticata; if these are drastically depleted by continued browsing, the abundance of birds that eat their nectar and fruit may also be reduced.
