This spider is named after Mrs. Priscilla M. J. van Andel, a Dutch wildlife enthusiast, who first collected this species with her husband Mr. J. H. Hans Raaijmakers.

[1] Males and females have pale golden short hairs on the body, with legs being barely darker and a noticeable lineal pattern on abdomen.

Males differ from other species of the Ischnocolus genus, except for Ischnocolus jickelii as the shape of the palpal bulb has a long embolus, tapering towards the apical end, with a slight fold at the apex.

Prey remains found in hide of this spider consisted of small darkling beetles.

The annual rainfall is about 45–154 mm a year, peaking in July, with the average temperatures being 27 °C.
