项目摘要

Members of the phylum Onychophora, commonly referred to as peripatus or velvet worms, are found to-day on land masses derived from the break up of Gondwana ; in South America, Africa, Australasia and a Gondwanan fragment that is now part of South-East Asia. In Australia, onychophorans belong to the family Peripatopsidae (also occurring in South Africa, New Zealand, New Guinea and Chile) and are restricted to the moist forests of the east coast from North Queensland to Tasmania, in the Mt.Lofty Ranges of South Australia and the south-western corner of Western Australia. Of the approximately 100 species of Onychophora world wide, Australia was reported to possess seven (Ruhberg, 1985 and further reviewed by Tait et al., 1990). However, Australia has recently been shown to possess a far greater radiation of these animals than previously reported. While many of these new species were initially identified by genetic techniques of allozyme electrophoresis (Briscoe & Tait, 1995) and chromosom … More e morphology (Rowell, et al., 1995), others are quite morphologically distinctive in possessing a variety of characteristic head structures in males used to carry spermatophores that are transferred to the genital opening of the female (Tait & Briscoe, 1990).Peripatus in Australia are found in moist micro-habitats of rotting logs, under logs and stones, in leaf litter and in soil. While some species would appear to be rare, others can be locally abundant. Some species are confined to small geographic ranges while others are more wide spread (Tait, pers.comm.).Euperipatoides leuckartii (Saenger) was the first species described from Australia in 1862 and redescribed its distribution reported to extend from southern Queensland to Tasmania.(Ruhberg, 1985). Another closely related species has been identified from Kanangra Boyd National Park in the adjacent Great Dividing Range.The specimens of Euperipatoides sp from this site will be formally described soon and hopefully in time to be included in any papers emanating from these studies. All speciments of Euperipatoides sp were obtained by breaking open rotten logs. The exact location of the site is 33^* 59' S 150^* 08' E. Less

爪毛虫门的成员，通常被称为毛虫或绒虫，今天在南美洲、非洲、澳大利亚和现在属于东南部一部分的冈瓦纳大陆碎片上发现。在亚洲，有甲虫属于拟甲虫科（也出现在南非、新西兰、新几内亚和智利），仅限于潮湿的森林。分布于从北昆士兰州到塔斯马尼亚州的东海岸、南澳大利亚的 Mt.Lofty 山脉和西澳大利亚州的西南角，据报道，在全世界约 100 种甲虫中，澳大利亚拥有 7 种（Ruhberg，1985 年和Tait 等人进一步审查，1990）然而，澳大利亚最近发现这些动物的辐射比以前报道的要大得多，而其中许多新物种最初是通过基因技术鉴定的。等位酶电泳 (Briscoe & Tait, 1995) 和染色体形态学 (Rowell, et al., 1995) 等其他技术在形态学上相当独特，因为雄性具有多种特征性的头部结构，用于携带被转移到精子的精子。雌性的生殖器开口（Tait & Briscoe，1990）。澳大利亚的 Peripatus 发现于腐烂原木的潮湿微生境中，在原木和石头下，在落叶层和土壤中，虽然有些物种似乎很稀有，但有些物种在当地却很丰富。 Euperipatoides leuckartii (Saenger) 是 1862 年在澳大利亚描述的第一个物种，并重新描述了其分布范围，据报道从昆士兰州南部延伸到塔斯马尼亚州。（Ruhberg，1985）另一个密切相关的物种是。鉴定自邻近大分水岭的卡南格拉博伊德国家公园。来自该地点的 Euperipatoides sp 标本将很快得到正式描述，并希望能及时纳入这些研究的任何论文中。所有 Euperipatoides sp 标本都是通过破碎获得的。打开腐烂的原木，该地点的确切位置是 33^* 59' S 150^* 08' E。
