This question is not about elections in a dictatorship to be generally either completely abolished or bogus elections. That should be clear. I try to find information whether especially womens right to vote was ever abolished in a country that already had granted womens suffrage.
I would expect such a measure to happen especially in a right-wing dictatorship, where the regimes ideology is often based on 'Return to the good old times'. One can easily imagine such a dictatorship to justify revoking womens voting rights with something like "Public affairs are Men's realm, while Women's realm is home and family".
It is quite difficult to find concrete information about elections in dictatorships, perhaps because such election were scams, anyway. But even the archetypical right-wing dictatorship - Nazi Germany - seems to have upheld women's suffrage. I found a contemporary report about the Reichstagswahlen 1938 (where the ballot consisted of the possibility to elect en bloc 'Hitler and the other Nazi party candidates', and nothing else) of a member of the working classes, where he reported what happened on that day in his town and how he and his wife Eva 'voted'.
The question is mainly about right-wing dictatorships of the 20th century, but also about information about other governments that might have revoked womens right to vote, like theocratic dictatorships.
(*edit: Clear up a sentence a little bit)
Francisco Franco's dictatorship revoked women's suffrage, as well as many other progressive laws passed by the defeated Second Spanish Republic.
The Second Republic's 1931 Constitution established women's right to vote, as well as the right to divorce. After Franco's victory in 1939, he revoked women's suffrage (although no one really had the right to vote, as Franco was dictator for life) and revoked multiple progressive laws, returning Spanish society to a state of thorough patriarchy. The provisions of the repealed 1889 Civil Code were reintroduced: women's economic activity such as contracts and salary were dictated by their husbands, a husband convicted of killing his wife's lover would receive a much shorter sentence than a wife who killed her husband's lover, and women were once again restricted from entering public office. Part of the logic behind that last restriction, and the logic behind reintroducing harsh penalties for abortion, was Franco's drive to repopulate Spain, which lost many citizens during the war. By restricting women to the home, penalizing abortion, and reintroducing patriarchal gender relations, he aimed to create a populous, strong, and loyal citizenry.
I apologize for not having much information on suffrage specifically - I do not know if there were even elections at all under Franco, but if there were, they were 1) exclusionary towards women 2) rigged so that Franco (and his supporters, in local elections) would always win.
