Abstract

<br> The Madagascar boulder pygmy grasshopper,<br> Pseudosystolederus sikorai<br> Günther, 1939,<br> syn. nov.<br> (Tetrigidae: narrow-vertex taxa related to<br> Xistrella<br> ), which is the type species of<br> Pseudosystolederus<br> Günther, 1939, is found to be conspecific with<br> Paratettix voeltzkowiana<br> Saussure, 1899. Thus,<br> Pseudosystolederus voeltzkowianus<br> (Saussure, 1899),<br> comb. nov.<br> becomes a new combination and has priority. The Madagascar boulder pygmy grasshopper is unique in its large tooth on the ventral margin of the mid femur and is relatively common on and around large boulders surrounding rivers throughout Madagascar. Photographs and measurements of the syntypes of<br> P. sikorai<br> syn. nov.<br> and<br> P. voeltzkowianus<br> comb. nov.<br> are presented together with new records, photographs of the species in its natural habitat, photographs of the habitat itself, and a brief discussion on the position of the genus<br> Pseudosystolederus<br> within Tetrigidae.<br> Morphopoides lesnei<br> Günther, 1979,<br> comb. rev.<br> is moved from<br> Pseudosystolederus<br> to the original combination.<br>
