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.
