Abstract

ABSTRACT The cestode, Bertiella musasabi Yamaguti, 1942 and four nematodes identified to at least genus level and adult specimens assignable to the Nippostrongylinae were recovered from nine of 20 individuals of Chiruromys forbsei Thomas, 1888. Five nematodes identified to at least genus level and adult specimens assignable to the Nippostrongylinae were recovered from 11 of 12 individuals of C. lamia (Thomas, 1897). Species of Parasabanema from C. forbsei and C. lamia, Parastrongyloides from C. lamia and Trichuris also from C. lamia could not be assigned to any known species. Hasanuddinia chiruromyos Smales, 2011a was previously reported from C. vates(Thomas, 1908). Helgenema lamia n. sp. differed from its congener H. keablei Smales, 2020 by its larger size, longer spicules and larger number of eggs in utero. Protospirura munimuniensis n. sp. from C. lamia was differentiated by having two denticles on each pseudolabium, males with the right spicule longer and more robust than the left, a V-shaped gubernaculum and six pairs of post cloacal papillae. Heligmonellids dominated the helminth assemblages of both hosts. Species richness, 80.6% species recovered for C. lamia,and 57% for C. vates was low in both hosts. Possible determinants of species richness were discussed.

新几内亚棘齿线虫和棘齿线虫的胃肠道线虫(啮齿类目:蝇蛆科)及原螺旋体(螺旋体科)一新种记述

摘要/ ABSTRACT摘要:从1888年的20只斑蝽(chirurromys forbsei Thomas)的9只个体中检出了1942年的musasabi Yamaguti小虫和4只鉴定为属级以上的线虫和可归属于Nippostrongylinae的成虫标本。从12只C. lamia的11只个体中发现了至少属水平的5种线虫和可归属于Nippostrongylinae的成虫标本(Thomas, 1897)。来自forbsei和C. lamia的parabanema种，来自C. lamia和Trichuris的Parastrongyloides种，以及来自C. lamia的Parastrongyloides种都不能归属于任何已知种。Hasanuddinia chiruromyos Smales, 2011a先前报道于C. vates(Thomas, 1908)。Helgenema lamia n. sp.不同于其同系物H. keablei Smales, 2020，它的体积更大，针状体更长，子宫内卵数量更多。原螺旋藻(munimuniprotospirura munimuniensis n. sp.)的分化特征为:每个假唇上有两个小齿，雄性的右针状体比左针状体长且结实，一个v形的管骨和6对后腔乳头。两种寄主的蠕虫组合中均以Heligmonellids占优势。物种丰富度在两种寄主中均较低，lamia恢复了80.6%，而vates恢复了57%。讨论了物种丰富度的可能决定因素。

期刊介绍： Published since 1880, the Transactions of the Royal Society of South Australia is a multidisciplinary journal that aims to publish high quality, peer-reviewed papers of particular relevance to Australasia. There is a particular focus on natural history topics such as: botany, zoology, geology, geomorphology, palaeontology, meteorology, geophysics, biophysics, soil science and environmental science, and environmental health. However, the journal is not restricted to these fields, with papers concerning epidemiology, ethnology, anthropology, linguistics, and the history of science and exploration also welcomed. Submissions are welcome from all authors, and membership of the Royal Society of South Australia is not required. The following types of manuscripts are welcome: Reviews, Original Research Papers, History of Science and Exploration, Brief Communications, Obituaries.
