对尿节虫属Ichnopus进行了修订，并将甘油列入其异名。为世界物种提供了一把钥匙。重新描述了该种的新种：Ichnopus pelagicus Schellenberg、I.Passoserricus Ledoyer、I.serricus Walker、I.spinicornisBoeck、I.Taurus Costa、I.tenuicornis(Haswell)、I.teretis(Andres)和I.wood Masoni(Giles)。记述了新种I.annasona、I.Capricornus、I.cartes、I.comorensis、I.cribensis、I.Malpatun、I.parriwi和I.wardi。Ichnopus nossibesis Ledoyer被认为是I.pelagicus的异名。大头金鱼被认为是一种面目全非的物种。两个种组被识别出来：棘角类群，其中节肢动物1的坐骨和腕部很长，大多数物种是中上层的，可能是微型捕食者；金牛群，节肢动物1的坐骨和腕部很长，大多数物种是底层食腐动物。伊克诺普斯被认为是..热带到暖温带的印度-太平洋属，在地中海和北大西洋东部有一些残留物。这两个物种中最原始的物种都在地中海和北大西洋东部。似乎现代属起源于古老的特提斯动物群。Lowry，J.K.和H.Stoddart，1992。刺头甲属的订正(甲壳纲：端足目：侧脚虾总科：尾足科)。澳大利亚博物馆纪录44(2)：185-245。185 Ichnopus是由Costa(1853)为地中海的I.Taurus建立的一个鲜为人知的uristid lysianassoidus属。自那时以来，已描述了13种，其中5种·目前被认为是异名。这些种中的大多数在文献中只被报道过一到两次。唯一的例外是I.Taurus Costa，1853和I.SpinicornisBoeck，1861，这两种动物都是经常被记录的，要么来自地中海，要么来自北大西洋东部。人们对这些动物的生物学、系统发育或动物地理学知之甚少。在本文中，我们重新定义了该属，识别了两个非正式的物种群，讨论了每一群中物种的栖息地偏好，并讨论了该属的一般动物地理分布。我们重新描述了8个种，并描述了8个新种。甘油属Glycerina Haswell，1882与Ichnopus Costa，j1853同名，与I.nossibeens Ledoyer，1986同名。Ichnopus macbetomma Stebing，1917被认为是一个无法辨认的物种。正文中使用了以下缩写：
The uristid genus Ichnopus is revised and Glycerina included in its synonymy. A key is provided to the world species. Ichnopus pelagicus Schellenberg, I. pseudoserricrus Ledoyer, I. serricrus Walker, I. spinicornis Boeck, I. taurus Costa, (type species), I. tenuicornis (Haswell), I. teretis (Andres) and I. woodmasoni (Giles) are redescribed. The new species I. annasona, I. capricornus, I. caritus, I. comorensis, I. cribensis, I. malpatun, I. parriwi and I. wardi are described. Ichnopus nossibeensis Ledoyer is considered to be a synonym of I. pelagicus. Ichnopus macrobetomma Stebbing is considered to be an unrecognisable species. Two species groups are recognised: the I. spinicornis group, in which the ischium and carpus of gnathopod 1 are long and most species are pelagic, probably micropredators; and the I. taurus group, in which the ischium and carpus of gnathopod 1 are very long and most species are demersal scavengers. Ichnopus is considered to be .. a tropical to warm temperate Indo-Pacific genus with some remnants in the Mediterranean and the eastern North Atlantic Ocean. The most primitive species in both groups are found in the Mediterranean Sea and the eastern North Atlantic. It appears that the modern genus had its origins in the old Tethyan fauna.

Records of the Australian Museum 44(2): 185-245. 185 Ichnopus is a poorly known genus of uristid lysianassoids which was established by Costa (1853) for I. taurus from the Mediterranean Sea. Since then 13 species have been described, five of which ·are currently considered to be synonyms. Most of these species have been reported in the literature only once or twice. The exceptions are I. taurus Costa, 1853, and I. spinicornis Boeck, 1861, both of which have been recorded frequently, either from the Mediterranean or the eastern North Atlantic.. Little is known about the biology, phylogeny or zoogeography of these animals. In this paper we redefine the genus, recognise two informal species groups, discuss the habitat preferences of species in· each group and discu9s the general zoogeographical distribution of the genus. We redescribe eight species and describe eight new species. The genus Glycerina Haswell, 1882, is synonymised with Ichnopus Costa, j1853, and I. nossibeensis Ledoyer, 1986, is synonymised with I. pelagicus Schellenberg, 1926. Ichnopus macrobetomma Stebbing, 1917 is considered to be an .unrecognisable species. The following abbreviations are used in the text:
