| description | The genus Amphictene is reported for the first time from Mexico. Previous records for America are restricted
to Brazil (A. catharinensis) (Grube, 1870), and Guatemala (A. guatemalensis) (Nilsson, 1928). In this paper
we describe a new species, Amphictene helenae sp. n., characterized by the presence of three pairs of
tentacular cirri, while other species have only two pairs. The new species is closely similar to Amphictene
catharinensis, and can be distinguished by the presence of a circular group of glandular papillae inserted
between the lines of glandular cirri present from the second segment. A. guatemalensis is redescribed based
on type material; it differs from the new species in the presence of two pairs of tentacular cirri on segments
1 and 2, six pairs of glandular cirri on the third segment, and four glandular lobes fused in pairs on the
fourth segment. |
