Notes. -

Bolívar (1898) described the species under the section Metrodorae as belonging to Xistra  , while earlier he described L. contractus  within the section Tettigiae, assigned to the genus Paratettix  . The two sections were distinguished by morphology of the lateral lobes—projected sidewards in Metrodorae, directed downwards in Tettigiae. When comparing types, I did not see differences in this feature.

Günther (1939) regarded L. contractus tricristatus  as a subspecies of L. contractus  , distinguished from the nominal by smaller size, sharper keeled prozonal carinae and, in lateral view, clearly visible fastigial horns (above the eyes). L. c. tricristatus  should be slightly smaller and should have wavy margins of the fore legs ( Günther 1935). All these features are, however, in the range of variation of the species and are not of diagnostic value. Moreover, I did not find reported differences when comparing the types. Otte (1997) gave the specific status to the subspecies only with the reason of occurrence on different islands.

All these data prove that L. tricristatus  ( Bolívar, 1898) is conspecific with L. contractus  .
