FIGURE 5 in Taxonomic consideration of eight Chinese bisexual Artemia populations, based on the morphology of frontal knob and gonopod and the result of cross-breeding tests

FIGURE 5. The distal gonopod spines of the bisexual Artemia from China. (A, B) Panoramic images of the gonopods of LGC (A) and BDJR (B) to show the position of three groups of distal gonopod spines (in B, the position of exolateral spines is arrowed). (C) Orthostichous spines of LGC. (D) Orthostichous spines of BDJR. (E) Posterior spines of LGC. (F) Exolateral spines of YIM. (G) Exolateral spine and spinules (arrowed) of CMC. BG = basal gonopod; BGS = basal gonopod spine; DG = distal gonopod; ES = exolateral spines; FT = finger-like tip; OS = orthostichous spines; PS = posterior spines. Abbreviations of Artemia populations see Table 1. Scale bars: A and B = 100 µm; C–F = 10 µm; G = 5 µm.
