. Zhou &amp; H. Ran, pers. comm.). The new species is apparently myrmecophilous because of the repeated circumstances of its collection, and it may possibly be a synoekete or a symphile due to the presence of what may be paired trichomes on the postocular margin. Similar trichomes of the head are commonly found in many myrmecophilous pselaphine genera, especially in the tribe

. The markedly constricted elytral base and loss of hind wings are typical for various myrmecophilous/termitophilous beetle groups. However, additional field observations are necessary to further reveal the biology of the new species.
