The origin of the specimen described by Spinola (1839) is unknown and Stål (1866) was the first to give a location for the species (Madagascar). Lallemand (1959) designated a lectotype in his collection (FSAG) that is invalid according to nomenclatural rules. Furthermore, the only labelled specimen of this species, [<i>Belbina servillei</i> Sign., V. Lallemand det., 1963], in Lallemand’s collection is in fact a specimen of <i>Belbina laetitiae</i> sp. nov., as demonstrated by the genitalia illustrated in Lallemand (1959). In order to avoid further nomenclatural confusion, a neotype is designated which perfectly matches the illustrations given by Spinola (1839) and which is deposited in a public collection (HMNH). I chose a male with genitalia in good condition to facilitate further work on the species.</p><p><b>Additional material</b></p><p>MADAGASCAR: 1 ♂, 2 ♀♀, no data (MNHN); 1 ♀, near Tamatave, A.
