Your assumption is incorrect; Solaris, unlike Linux, Digital UNIX, and the
BSDs, does *not* support capturing on loopback interfaces.  See the
"supported media" page:

    http://www.ethereal.com/media.html

for information on the types of network devices on which libpcap/WinPcap
(the capture library used by Ethereal - and tcpdump/WinDump, and snort,
and a number of other network traffic capture-and-analysis programs -
uses) can capture traffic.  (In most cases, a "No" means that the
underlying OS doesn't support it, so libpcap/WinPcap can't support it.)
