FAMILY DIOSACCIDAE

KGG 260 – characters

Note: The results obtained by using this key must be treated with caution as the species involved are rather difficult to separate. Reference to a good description is essential for confirmation. In many cases it is possible only to separate the males, not the females.

1. A.2 Exp.2.

n – number of setae.

2. P.4 Exp.3.

wd – distal seta of the inner border is well developed.

sw – distal seta of the inner border is small and weak.

3. A.1 (F)

n – number of segments.

4. A.1 (F)

p – plumose setae present.

a – without plumose setae.

5. (M) P.1 Basis.

ml – inner spine modified and very long (see Fig. 40).

s – inner spine usually not modified, or if modified then it is always short.

6. P.5 (M)

n:n – number of setae on Benp. and Exp. respectively.
