The only species with which this can be confused is C. tégripes, which is larger, 
and has an unbanded proboscis and more numerous spots on the legs; the 
thoracic scaling is also quite different. C. quasigelidus has a very distinct 
appearance, as might be supposed from the fact that three genera have been 
erected for its special benefit. One of these, Lastoconops, was founded on a 
specimen which had a number of scales of some Lepidopteron adhering loosely 
to its abdomen. Some specimens of Pseudoheptaphlebomyia sent to the British 
Museum by Dr. Ventrillon are undoubtedly this species. In this and the two 
following allied forms the pale front two-thirds of the thorax is often more 
marked in the ¢ than in the ©.
