Two French climbers were still unaccounted for as of Monday afternoon, the French Foreign Ministry said.
The aerial search for the missing has ended, but officials said Sherpa guides were continuing to search the snowy slopes.
The avalanche hit about 4 a.m. Sunday while more than two dozen climbers were sleeping in tents at Camp 3 on Mount Manaslu.
Three French climbers and two Germans were transported to hospitals in Katmandu on Sunday. Two Italians were flown there Monday -- Mondinelli, who has climbed the world's 14 highest peaks, and fellow mountaineer Christian Gobbi.
Mondinelli said a third Italian climber and their Sherpa guide were sleeping in another tent and both were buried by the avalanche and died.
Mondinelli and Gobbi looked out of their torn tent after the avalanche, but with no light, they saw nothing. "We found someone's boots and put them on," Gobbi said.
When the sun rose, they said, they were able to assist the injured with the help of Sherpa guides who came up from lower mountain camps. The survivors who could walk made their way down to the base camp while those who more seriously injured were picked up by helicopters.
The Nepal Mountaineering Department identified the eight recovered bodies as Fabrice Priez, Philippe Lucien Bos, Catherine Marie Andree Richard and Ludovic Paul Nicolas Challeat of France; German Christian Mittermeyer; Italian Alberto Magliano; Spaniard Marti Roirg Gasull; and Nepali Dawa Dorji.
At least three of the victims were from the French Alps town of Chamonix, a hub for climbers on Mont Blanc and nearby peaks. An avalanche on a route to the summit of Mont Blanc in July killed nine experienced climbers.
Sunday's avalanche came at the start of Nepal's autumn climbing season, when the end of the monsoon rains makes weather in the high Himalayas unpredictable.
Spring is a more popular mountaineering season, when hundreds of climbers crowd the peaks.
Mount Manaslu, which is 8,156 meters (26,760 feet) high, has attracted more climbers recently because it is considered one of the easier peaks to climb among the world's tallest mountains.
A total of 231 climbers and guides were on the mountain, but not all were at the higher camps hit by the avalanche.
Nepal has eight of the 14 highest peaks in the world. Climbers have said in recent years that conditions on the mountains have deteriorated and risks of accidents have increased, with some blaming global warming.
Avalanches are not very frequent on Mount Manaslu, but in 1972 one struck a team of climbers and killed six Koreans and 10 Nepalese guides.
