Comments.

Five related species with close geographical distribution, Chaerilus assamensis : Kraepelin, 1913, Chaerilus conchiformus , Chaerilus dibangvalleycus , Chaerilus mainlingensis , and Chaerilus tryznai , all with 7-8 granulated cutting edges on the movable fingers of pedipalp ( Bastawade, 2006; Di & Zhu, 2009; Kovařík, 2000a; Zhu, Han & Lourenço, 2008). Chaerilus assamensis was described by type specimen from Assam (India), its original description is poor (see Kraepelin, 1913). Kovařík (2000a: 69), who analysed the old reference, recorded three characters of Chaerilus assamensis : middle and lateral eyes present; 7-8 granulated cutting edges on the movable fingers of pedipalp; the anterior margin of carapace arched in males. Lourenço and Duhem (2010) thought Chaerilus tryznai , with few differences from Chaerilus assamensis , may prove to be conspecific. Both sexes of Chaerilus conchiformus , Chaerilus dibangvalleycus and Chaerilus tryznai have anterior margin truncated,but only females of Chaerilus mainlingensis have same anterior margin of carapace as Chaerilus dibangvalleycus . Except Chaerilus assamensis with poor information, other 4 species can be identified by the key provided in this paper.
