Also, gonopod morphology is constant or has very limited variation at intraspecific level in both species (Brandis et al., 2000).
The usage of CL as the primary character accounted for six cases (14%) whereas gonopod length, sixth abdominal segment width, and short carapace width were each used once as primary characters in estimating female brachyurans' size at morphometric maturity (Fig.
First male gonopod an amber color, consisting of two unequal lobes laterally compressed with a medial groove; the shaft portions are membranous or weakly calcified (fig.
In his brief description, Chamberlin (1942) presented illustrations of the left gonopod of the male and dorsal views of the 11th and 13th paranota, and stated that M.
The following morphological characteristics were measured: the carapace width (CW), the height and length of the major cheliped propodus (LPH and LPL), the width of the female abdomen at the base of the 4th somite (AW) and the length of the male gonopod (GL).
The morphometric measurement of carapace, abdomen, cheliped and male gonopod were related to carapace width as an independent variable.
We observed preliminary differences in first form male gonopod structure, branchiostegal tubercle presence, chelae shape, size of first form males, and pigmentation (Simon unpubl.
