Diagnosis. Larvae of C. femorata can be distinguished from other representatives of the insolta complex by the following combination of characters: (i) head with large genae ( Figs 113 View FIGURES 112–113 , 114 View FIGURES 114–118 ); (ii) body, especially mid- and hindfemora, significantly flattened ( Figs 113 View FIGURES 112–113 , 117, 118 View FIGURES 114–118 ); (iii) projections of pronotum large, directed forward ( Figs 113 View FIGURES 112–113 , 115 View FIGURES 114–118 ); (iv) projections of mesothorax not notched ( Figs 113 View FIGURES 112–113 , 115 View FIGURES 114–118 ); (v) inner margin of forefemur without large projections or chalazae (only occasionally with one or two small chalazae) ( Fig. 116 View FIGURES 114–118 ); (vi) outer margins of mid- and hindfemora strongly serrated ( Figs 113 View FIGURES 112–113 , 117, 118 View FIGURES 114–118 ); (vii) inner margins of mid- and hindfemora without serration ( Figs 117, 118 View FIGURES 114–118 ); (viii) outer margin of middle femur with well-developed apical projection ( Fig. 117 View FIGURES 114–118 ); (ix) paired abdominal tergal projections without bifurcation.

Distribution. Northern parts of Vietnam ( Tshernova 1972) and Thailand ( Gose 1969, Jacobus et al. 2005, Jacobus & McCafferty 2008, new data), and southern part of mainland China ( Xie et al. 2009) ( Fig. 153 View FIGURE 153 ).

Habitat. Cold, st flowing streams and rivers. Larvae appear to prefer pebble, detritus, leaf litter and roots as substrate.

Remarks. The larva of this species was described in detail by Gose (1969) and Tshernova (1972). We illustrate the main distinguishing characters of the species ( Figs 113–118 View FIGURES 112–113 View FIGURES 114–118 ) for comparative purposes.
