The description is based on a single female specimen recovered from a rice field.

[1] C. parangexanthematica is classified under the genus Cyrtophora (tent-web spiders) and the subfamily Cyrtophorinae.

On the middle of the upper surface was a distinctive black triangular spot surrounding by eight sigilla (small pitted depressions) arranged in two rows.

Like its namesake, C. parangexanthematica had two blunt projections at the posterior end of its abdomen, a pair of 'humps' on the forward part, and a pair of white lines running from the tip of the 'humps' down to below the projections on its rear end.

The spinnerets were bordered with white rings and the bottom of the abdomen had pale spots.
