Four further species which could be confused with the H. frater-praenanus group are discussed and illustrated. These are H. croaticus KUWERT, 1886, H. pumilio ERICHSON, 1837, H. pitcheri ANGUS, 1970 and H. shatrovskyi ANGUS, 1985. Additional faunal records of Helophorus FABRICIUS species from the Tibetan Plateau and other areas of China are given. Helophorus tuberculatus GYLLENHAL, 1808 is recorded from Bhutan for the first time
