Remarks: The adult male and female of Polyplax insulsa were described and illustrated by Ferris (1923). Polyplax insulsa mainly infests members of the subfamily Murinae and has a patchy distribution in the Indo-Malayan Region (Chin 1980; Durden & Musser 1994). A single female of P. insulsa recorded from Sundamys muelleri in Kuala Lumpur may be a straggler (Johnson 1964).
