FAMILY ANCORABOLIDAE
In this family the endopods of P.1-P.4 are often reduced to small
stumps, or at least the first segment is so reduced, thus making it difficult
to count the number of segments without rigorous examination. Also, the setae
on these segments are often very small. Any determination arrived at by the use
of this key must be checked against an adequate description.
KGG 1 – characters
1. P.1*
n:n – number
of segments in Exp. and Enp. respectively.
2. P.2 and P.4 Enp.*
n:n – number
of segments in P.2 and P.4 respectively.
3. P.1 Exp. distal segment.
n – number
of setae and/or spines.
4. P.2-P.4 Exp., distal segment.
n:n:n –
number of setae and/or spines on P.2, P.3 and P.4 respectively.
5. P.2 and P.4 Enp. distal segment.
n:n – number
of setae on P.2 and P.4 respectively.
na – not
applicable (Enp. absent).
* In characters 1 and
2 the suffix r indicates that the segment is rudimentary, but
distinguishable.
