摘要

。石竹属两新种记述(甲壳目:等足目),1925。uallagirus sp.n。P;irystonicus sp.n。,描述自Alagyr峡谷(北奥塞梯-阿拉尼亚,俄罗斯)的地下水。这些样本是在Terek河流域和北高加索地区发现的第一批Proasellus代表。这两个物种在形态上与外高加索种接近,特别是P。线性(Birstein, 1967),但可以很容易地通过几个字符来区分。P。uallagirus sp.n。拟足类的多足体形状、外足体和内足体的大小比例以及内表面的武装均存在差异。P。irystonicus sp.n。也不同于准足类I-VII的武器装备。这两个新种可以很容易地通过腕足类I-VII肢的腕足、体型和一些腕足类的特征来区分。

Two new stygobiotic species of the genus Proasellus (Crustacea: Isopoda: Asellidae) from the North Caucasus
. Two new stygobiotic species of the genus Proasellus Dudich, 1925 (Crusta-cea: Isopoda), P . uallagirus sp.n. and P . irystonicus sp.n., are described from ground waters of Alagyr Gorge (North Ossetia – Alania, Russia). These samples are the first Proasellus representatives found in the Terek River basin and in the North Caucasus. Both species are morphologically close to the Transcaucasian species, especially P . linearis (Birstein, 1967), but can be easily distinguished by several characters. P . uallagirus sp.n. differs in shape of pleopodes, size ratio of pleopod exopodites and endopodites, and arming of internal surface of the pereopod I propodus. P . irystonicus sp.n. also differs in arming of pereopods I–VII dactiluses. The two new species can be easily distinguished from each other by armature of pereopod I–VII dactiluses, body size, and some characters of pleopods,

期刊介绍: Scientific peer-reviewed journal INVERTEBRATE ZOOLOGY publishes original papers, reviews and brief communications on morphology, anatomy, embryology, taxonomy, phylogeny, and ecology of any group of invertebrates from protistans to lower chordates. INVERTEBRATE ZOOLOGY accepts manuscripts in English or Russian and publishes them in printed and electronic versions. The Russian translations of English titles, abstracts and figure captions of the papers written by non-Russian authors can be provided by the editors. Invertebrate Zoology invites authors to publish extended monographic manuscripts after usual reviewing procedure. The monographic manuscripts can include up to 400 thousand letters and be prepared in English or in Russian. Accepted monographic manuscripts will have priority to be published in the nearest issue of the journal.
