摘要

波尔，G.C.B.， 2015。Halearcturus，南极洲科一新属，2001(甲壳纲:等足目:Valvifera)。维多利亚博物馆回忆录73:13-18。为一种Arcturus serrulatus Whitelegge, 1904建立了Halearcturus新属。它与所有其他南极洲属的不同之处在于，它的触角鞭毛是由一根主要的毛和一根短的弯曲的尖毛组成的(所有其他属都有三根或四根毛，或者大约九根，再加上一根末端的毛)，而且不寻常的是，它没有尾足外足动物。Halearcturus具有独特的复杂纹饰;它缺乏坚固的内侧后棘和一对突出的下外侧棘，这是其他南极动物的典型特征。该属仅有一种产于澳大利亚东南部。给出了南极科属的一个键。

Halearcturus, a new genus of Antarcturidae Poore, 2001 (Crustacea: Isopoda: Valvifera) with a key to genera of the family

Poore, G.C.B. 2015. Halearcturus, a new genus of Antarcturidae Poore, 2001 (Crustacea: Isopoda: Valvifera) with a key to genera of the family. Memoirs of Museum Victoria 73: 13–18. A new genus Halearcturus is erected for a single species, Arcturus serrulatus Whitelegge, 1904. It differs from all other antarcturid genera in the combination of having an antennal flagellum of one major article plus a short curved tapering article (all other genera have either three or four articles, or about nine, plus a terminal one) and is unusual in lacking a uropodal exopod. Halearcturus has unique complex ornamentation; it lacks both a strong medial posterior spine and a pair of prominent sublateral spines on the pleotelson, typical of other antarcturids. The genus has a single species from south-eastern Australia. A key to genera of Antarcturidae is presented.
