Etymology

The new species name is derived from its characteristic gibbosity on the anterior part of pronotum.

Comments

This new species resembles C. obscura in its body outline and sculpture; however, it can easily be distinguished from the latter by its strongly swollen anterior part of pronotum, forming a gibbosity just at the base of the head ( Figures 1 and 2 View Figures 1–6. 1–4 ), its varying shape of paramere ( Figures 3 and 6 View Figures 1–6. 1–4 ) and spermatheca ( Figures 4 and 6 View Figures 1–6. 1–4 ). Both these differ in the colour of sternites ( C. obscura – pale brown; C. gibbosa – uniformly yellow), and of legs ( C. obscura – pale brown; C. gibbosa – femur and tibia brownish red, and tarsi black).
