FIGURE 32 in New genera for species of Jassa Leach (Crustacea: Amphipoda) and their relationship to a revised Ischyrocerini

FIGURE 32. Pleojassa wandeli (Chevreux, 1906). Variation in gnathopod 2 thumb length and propodus length relative to body length in males and females from a single population (Billie Rocks, Signy Island, South Orkney Islands, 5 March 1965, M. H. Thurston, coll., NHM 1969:735:39, station no. 10(95)). The male 1 and male 3 illustrated in FIGURE 30 and the female illustrated in FIGURE 33 are indicated by an arrow. Linear regression assumptions passed for the adult female. Linear regression statistics: Adult female, thumb length = -0.455 + 0.229 x body length, r2 = 0.932, n = 11.
