Thanks Dr Seow for your insights. I'd hate to complicate matters, but could it be possible that berenice might occasionally have more pointed striae in spaces 4 and 5 like this?

Here are two more- the first i'm very certain is a female calauria based on the points discussed. The second is a male and i'm less certain but i think it's a male calauria even though striae 4 and 5 are less pointed. This was the only decent shot i could manage:/
