He has called up uncapped Tsepo Seturumane, who finished as top scorer in the recently completed Basotho Premier League, as well as Lioli teammate Ngoako Mapheele and Linare striker Moorosi Tsiu.
Seturumane finished the season with 16 goals for the new champions.
"He has shown a lot of promise and potential and we hope that he can bring his goal-scoring touch to the team," Notsi told reporters.
"The reason behind his selection was because of his abilities as a striker and the technical team will be looking to him to fix the team's goal-scoring problems."
Experienced defender Nkau Lerotholi also returns after problems between his club Matlama and the Lesotho Football Association were resolved.
The squad will also be used for Lesotho's two World Cup qualifiers next month, away in Zambia first and then home to Ghana's Black Stars.
Notsi has kept faith in the main with the players who pulled off a 1-1 draw with the Zambians in Maseru in March in a World Cup upset.
It means the Basotho will have three foreign-based players, two of them from the third tier of South African football.
Notsi has also changed his back-up goalkeeper by bringing in Lesotho Correctional Services' Kholue Phasumane but said he will stick with first choice Mohau Kuenane, despite a lack of game time at Lioli where he has been embroiled in conflict with officials.
"Continuity is very important at this stage," Notsi said. "I have tried a number of young and promising keepers in the league, but we had to keep our faith in Kuenane because he has been part of the team for a very long time."i
