Diagnosis Genus diagnosis. Gammariform amphipods from SW Europe (Iberian Peninsula), similar to
Homoeogammarus, but with markedly different gnathopods; gnathopod propodite II only less than
80% length and up to 60% width of propodite I. Uropod III endopodite 20-50% exopodite length,
linear, with a terminal and one or more marginal spines; exopodite with marginal groups of spines
and variable setation.
Remark. The most reliable marker of Iberogammarus is the smaller and particularly the narrower
gnathopod II propodite, which also differs remarkably in shape with its very short palmar margin. Besides, the uropod III endopodite bears also a marginal spine which is normally absent in
Homoeogammarus; the setation and the endopodite length are very variable. [details]
