A limited-area survey of the \eta Chamaeleontis cluster has identified 2 new late-type members .
The more significant of these is ECHA J0843.3–7905 ( = IRAS F08450–7854 ) , a slowly-rotating ( P = 12 d ) M2 classical T Tauri ( CTT ) star with a spectrum dominated by Balmer emission .
At a distance of 97 pc and cluster age of \approx 9 Myr , the star is a nearby rare example of an ‘ old ’ CTT star and promises to be a rewarding laboratory for the study of disk structure and evolution in pre-main sequence ( PMS ) stars .
The other new member is the M4 weak-lined T Tauri ( WTT ) star ECHA J0841.5–7853 , which is the lowest mass ( M \approx 0.2 M _ { \odot } ) primary known in the cluster .
