Notes Form I male (i.e. breeding condition) ventral view, anterior at top. Shows two first pleopods (gonopods), arrowed. These have been raised up slightly from the normal resting position where they are less visible. When viewed mesially, as in image 76950, they are an important feature for species determination.
