The number of spines on AP3–AP5 varies considerably. Spines are usually present on AP3 with the majority of AP3 pleura having 3–5 spines, but the number is very variable and wide ranging. Only 12 (n = 74) shrimps were found with the same number of spines on both left and right pleura of AP3; no AP4 pleura examined lacked spines. AP4 usually has a single, more prominent posterolateral spine but in five pleura spination was continuous and undifferentiated around the posterolateral curve; AP5 almost invariably has a major posterolateral spine (a single pleuron lacks spines altogether), 74% of AP5 pleura have either three or four spines usually above the major spine on the posterior margin of the pleuron although a single specimen has spines (three) on the lateral border anterior to the major spine (for illustrations of variation in pleural armature of

However, there was no significant correlation between CL and any of the other characters analysed, viz. carapace dorsal spines (r = ­0.20, n = 40, p&gt;0.2), right P3 merus (r = 0.03, n = 33, p&gt;0.5), right abdominal pleuron 5 (r = 0.08, n = 40, p&gt;0.5), right telson dorsolateral spines (r = ­ 0.14, n = 29, p&gt;0.2) and telson posterior setae (r = 0.23, n = 28, p&gt;0.2). This lack of correlation holds for both females and males, although the male sample is very small with data for less than ten counts from each character available for analysis.
