Voiceless pharyngeal fricative

The voiceless pharyngeal fricative is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is an h-bar (which resembles the Cyrillic lowercase letter Tshe), $\langle\rangle$. Epiglottals and epiglotto-pharyngeals are often mistakenly taken to be pharyngeal. In academic writings, it is often distinguished by writing a diacritical point beneath the letter, as in Ḥ or in ḥ.
