 Remarks. According to the original description, additional denticle of female gonopodal claw is very short, but this denticle is well-developed in large specimens (Fig. 5).   
This species is new to the fauna of Kyrgyzstan.  
 H. pervagatus has never been recorded from altitudes exceeding 4500 m (Zalesskaja 1978). The present record from 4700–4900 m is the highest record of Chilopoda in Middle Asia (Table 1).
