WIDS suffered an ill-timed dip in form to gift a victory to their struggling hosts in South Lancs Cheshire One.
The Heath Road side certainly came down to earth with a bang after their heroics against Sale and Wirral.
Widnes made virtually all the first-half running and must have been hopeful when, midway through the first half, Kevin Farrow crashed over from short range.
However, this lifted Anselmians, who hit back with a penalty goal and a try to lead 8-5.
Widnes never got their challenge off the ground after the restart and Anselmians scored four tries in a 15-minute purple patch to take the game away from the visitors.
Andy Riley responded with two tries in the final quarter but it was too little and too late.
Widnes were left to regret too many missed opportunities and tackles.
Widnes have a blank weekend which may be a blessing as they can try to regroup in time for the a vital league clash at Sale FC before a welcome Christmas break.
* Widnes 2nd 0 Blackburn 2nd 34: Blackburn ran out convincing winners as last season's two promoted clubs went head-to-head again.
But the first 30 minutes gave little indication of things to come.
The game was fairly even until Widnes suffered a sinbinning.
Blackburn capitalised with two quick tries for a 12-0 lead.

Simon Duffy and newcomer Dave Lightfoot were the pick for Widnes while Andy McIntosh, at stand-off, continued his recuperation from injury with some pinpoint kicking during open play.
Widnes travel to Tyldesley this weekend in a re-arranged fixture.
* Sandbach 3rd 12 Widnes 3rd 43: Widnes laid the ghost of their horror show against Wirral to rest.
The return of seasoned campaigners Graham Riley and Brian Gill at half-back helped them.
But it was in the forwards where the important work was done.
Andy Rigby, Ron Clark and MoM Vaughan Evans created space for Si Bruce to plunge his way over for a hat-trick of tries in the first 20 minutes.
Winger John Maher also crossed at the corner on his comeback from injury.
In between, Sandbach had responded with two excellent tries.
But before half-time, veteran scrum-half Riley dummied over from 20 metres to stretch Wids' advantage.
Widnes will have been delighted to have kept a clean sheet in the second half when they added two tries through Gill and replacement winger Charles.
* Widnes U17s 12 Ashtonon-Mersey 11: Off-key Widnes still managed to call the tune for a narrow victory.
In terrible conditions, Widnes were again somewhat below their best but claimed the league points.
Wids' forwards started strongly through Williamson, Bennett and man of the match Mahoney.
The Heath Road side went ahead after a quarter of an hour, Harrison came onto a short ball from Winstanley to score, converting himself.
AoM hit back just before half-time with a try from a well-worked lineout.
Widnes' reply after half-time was quick and to the point.
O'Connor made the initial break and the ball was recycled by Varley - enabling the backs to send winger Semple to the corner.
Two AoM penalties reduced their deficit to a single point, but the Wids held out for a hard-earned victory.
* Widnes U11s avenged their first team's defeat with a 57-7 spree against Aldwinians with a nine-try display.
This was the best performance of the season and they could well afford to have three tries disallowed.
Although the backs shared eight of the legitimate touchdowns, the forwards had done the spadework with the smaller Aldwinians pack unable to cope.
Aldwinians scored late on but by then, Widnes were out of sight thanks to tries from Gagen (4), Paton, Kenyon, J Ellison, Foster and Lowe. Gagen also kicked four goals to a couple from Smith.
