there are no apical dark bands on the venter of the abdomen. The very 1 
characteristic pleural ornamentation in this mosquito is not present in 
C. Yiridis. The most marked feature of this mosquito is undoubtedly the 
pleural markings namely the creamy line covered with white scales flanked 
on either side by a dark brown unsealed line.
