Abstract

A new gammarid Dursogammarus dromaderus gen. et sp. nov. (Amphipoda: Gammaridae) is described from coastal Black Sea habitats of the southwestern foothills of the Russian Caucasus, being an obligate dweller of coastal pebbles. The new species morphologically resembles representatives of Echinogammarus Stebbing, 1899 and Dikerogammarus Stebbing, 1899, and somewhat Gmelina G. O. Sars, 1894, but can be easily separated by a unique combination of morphological features not characteristic for the latter genera. The most remarkable features are the presence of a dorsal knob (tubercle) on urosomal segment I as well as the long and wide outer ramus (exopod) of uropod III with mostly reduced distal article. http://www.zoobank.org/urn:lsid:zoobank.org:pub:846A98BC-D67B-4F4A-9E08-C6FF6FE9017A

来自高加索山麓海岸卵石栖息地的一种新的滨-里海gamma marus dromaderus gen. et sp. nov.(片足纲:gamma maridae)

在俄罗斯高加索西南山麓黑海沿岸栖息地发现了一种新的伽马marus dromaderus gen. et sp. nov.(两栖目:伽马maridus gen. et sp. nov.)，它们是沿岸鹅卵石的专性居民。新种在形态上类似Echinogammarus Stebbing(1899)和Dikerogammarus Stebbing(1899)的代表种，以及Gmelina g.o. Sars(1894)的代表种，但可以很容易地通过一种独特的形态特征组合将后者所不具有的特征区分开来。最显著的特征是在尿体I节上存在一个背丘(结节)，以及尿足III的长而宽的外支(外足)，远端节大部分缩小。http://www.zoobank.org/urn:lsid:zoobank.org:pub:846A98BC-D67B-4F4A-9E08-C6FF6FE9017A
