Some appendages of a female
paratype
(USNM 194419) were examined to estimate their variability.

Carapace size
(mm): USNM 1021379, length with anterior process 0.60, length excluding anterior process 0.54, height 0.46.
First antenna
: USNM 194419, 1st and 2nd segments forming right angle (
Fig. 13

). Same as 1st antenna of adult female illustrated by
Kornicker & Iliffe (1998
: fig. 51
d,e
).
Second antenna:
USNM 194419, except for minute lateral spine-like bristle near dorsal margin of 2nd segment being barely visible using oil immersion objective, endopod similar to those of adult female illustrated by
Kornicker & Iliffe (1998
: fig.
51
g
,h)
Mandible:
USNM 194419, endite of basis with 4 lateral bristles (2 long, 2 short) on left limb and 5 on right limb (3 long, 2 short). (Right limb differs from basis of both left and right mandibles of adult female illustrated by
Kornicker & Iliffe (1998
: fig. 51
j,k
) in having 3 instead of 2 long lateral bristles.)
Variability.
Second antenna:
2nd endopod segment with minute lateral spine-like bristle near dorsal margin (indistinct on some specimens).
Mandible:
basis endite with 2 or 3 long lateral bristles.
Supplementary description of adult male.
Carapace size
(mm): USNM 1021378, length without anterior process 0.48, height 0.44.
Remarks.
The species is reported for the first time in Basil Minn’s Blue Hole.
