Wanted :
Help us to check the distribution of the following grasshoper (Acrididae, Gomphocerinae) : The distribution of this species
in the Mediterranean region is fragmentary, and poorly documented.
B. tryxalicerus
has been found only in scattered areas of Iberian and Italian
Peninsulas, Sicily and Egypt. It could be considered as the remnant
of an ancient distribution range all over the southern Mediterranean
region. Its absence from North Africa may reflect however its
difficult detection and the lack of investigations in its natural
habitats. B. tryxalicerus lives in 'garrigues' on limestone
rocky hills, with high winter rainfall and hot dry summer. It
may be confused with one species of Ochrilidia, from which
it differs by the shape of foveolae and the presence of a
prosternal tubercle, absent in Ochrilidia.
Any information, photograph and/or
collected specimens would be greatly appreciated. Viglioglia

Tow complementary approaches are proposed.
- A "Key to species" menu allows with the aid of Xper, a software to identify specimens at the species level or at the genus level.
- A "Species Index" menu provides an access to descriptive cards with pictures, key-characters for identification and distribution maps.
