I agree, too, with the identification of your specimen as Neolovenula alluaudi. please read the paper Alfonso and Belmonte 2013, where a descritpion is given. in addition, I personally am interested in the distribution of this species. it is typically absent from the central Mediterranean (and also is not reported from Tunisia) but very common in Sud-Sahara, and, in Europe, in the extreme West and in the extreme East, without any report from the central geografic area.
