This article is devoted to study the solvability of the Riemann–Hilbert problem, with arbitrary index, for the Cauchy–Riemann operator in a lens and two complementary lunes. We generalize the corresponding results obtained by Begehr and Vaitekhovich (Complex Var Elliptic Eqs. 2014;59:76–84). The parqueting-reflection technique is used. The boundary behaviour of related integral operators of Schwarz type and Pompeiu type is discussed. Then the expressions of the solutions are explicitly obtained.
