<paragraph pageId="62" pageNumber="79">As noted above, the armature of the dactyls of pereopods 2 and 3 is noticeably variable among the numerous specimens examined of this new species. The dorsomesial and ventromesial margins vary in armature from having bristle-like setae and obscure or altogether lacking any clearly visible corneous spines (e.g., in the holotype, Fig. 26B, D) to the margins armed with long, slender, corneous spines. When corneous spines are present, they can be arranged in dorsomesial and ventromesial rows of single spines (pereopod 2), or in rows of 1-3 clustered spines (pereopod 3). The presence or strength of the armature of the dactyls do not appear to be related to size of the specimens.</paragraph>
|
||
<paragraph pageId="62" pageNumber="79">In the 25 males examined, the presence of left unpaired pleopods 3-5 is variable, as follows: 77% have reduced, biramous left pleopod 3; 55% have a reduced, uniramous pleopod 4; and 11% have a reduced, uniramous pleopod 5; 22% lack pleopods 3-5 altogether; no male specimens were found to have pleopods 3-5 on right side. Virtually all 22 females examined had pleopods 2-4 only on the left side and lacked pleopod 5. However, 10% of the females had a uniramous, vestigial pleopod 5. Only one ovigerous female (3.8 mm, CBM-ZC 14205) from Ogasawara Islands, Japan, was found to have right unpaired pleopods 2-4.</paragraph>
