A new dracunculoid genus and species, Moravecia australiensis, is described from gill-filaments of the green porcupine fish Tragulichthys jaculiferus (Cuvier) (Tetraodontiformes: Diodontidae) from Moreton Bay, Queensland, Australia. Abundant mobile larvae and a few adult males with females occurred in the gill-filament between the epithelial basement membrane and efferent artery. Gills of all 69 fish examined contained larvae. Eleven harboured adult nematodes of a previously undescribed species belonging to the family Guyanemidae. The new species is placed within a newly proposed genus because it differs from the four existing genera in the family in possessing fine cuticular transverse striations, two forward protruding cephalic elevations, a circumoral elevation, a small triangular mouth surrounded by six cephalic papillae arranged in two lateral clusters of three each and a pair of large lateral amphids. Males have two pairs of pedunculate caudal papillae supporting the caudal alae. A key to the genera of the Guyanemidae is presented.
一种新的龙线虫类属种——澳大利亚莫拉线虫（Moravecia australiensis），是从澳大利亚昆士兰州莫顿湾的绿河豚鱼（Tragulichthys jaculiferus，居维叶）（鲀形目：二齿鲀科）的鳃丝中描述出来的。丰富的活动幼虫以及一些成年雄性和雌性个体出现在上皮基底膜和出鳃动脉之间的鳃丝中。所检查的69条鱼的鳃中都有幼虫。其中11条鱼体内藏有属于圭亚那线虫科的一个先前未描述过的物种的成年线虫。这个新物种被归入一个新提出的属，因为它与该科现有的四个属不同，具有精细的角质层横向条纹、两个向前突出的头部隆起、一个口周隆起、一个被六个头部乳头包围的小三角形口，这些乳头排列成两个每组三个的外侧簇，还有一对大的外侧化感器。雄性有两对带柄的尾乳头支撑尾翼。文中给出了圭亚那线虫科各属的检索表。
