M. Simon (Act. Soc. Linn. Bord. xliv. p. 330) also records this species from 
Guatemala. The Guatemalan specimen, a female, has been carefully examined by 
me, and its specific identity with Crypsidromus perniz, Auss. (the male type of which 
is before me), is doubtful.

2 (imm.)..The hues of the abdomen are much more conspicuous than in the adult. Carapace, legs, and 
sternum uniform pale chocolate-brown. Abdomen with pale orange central dorsal area, sometimes darker 
towards the apex, with five conspicuous rich orange transverse oblique lateral slashes, alternating with 
deep black intervals, narrower and more closely adjacent towards the spinners. Ventral area orange, 
with a broad black dentate central band. ‘The disposition of the bands and the coloration of the dorsal 
area vary with individuals.
