Dorsal shield with 32 pairs of setae, including 6 pairs of elongate setae, 3 pairs in podonotal and 3 pairs in opisthonotal regions; 6 pairs of posterior R -series setae and J5 inserted on a narrow band attached to the ventrimarginal shields; setae st3 length equal to, or exceeding, the medial length of the sternal shield or the distance between setae st1 and st3 ( Figure 18 )............................................................................................ C. gangeticus Elsen, 1975
