Notes. -

Bolívar (1898) described the taxon as a variety of Xistra tricristata . In contrast to L. tricristatus , the prozonal carinae are not curved to the middle and not keeled. The margins of the fore legs are slightly undulated. Günther (1935) synonymized Xistra tricristata var. sumatrana with Paratettix contractus without giving details. According to Günther (1939), the specimens of L. sumatrana have in lateral view only slightly visible elevated lateral carinae above the eyes and wavy median carina in front of and behind the shoulders. In the specimens of L. contractus from Borneo, these undulations are weaker. Otte (1997) gave the subspecies a specific status based on occurrence on different islands (as in L. tricristatus mentioned above). All these features are within the range of variation of the species and do not represent diagnostic traits. I did not find differences when comparing the types and, therefore, L. sumatrana ( Bolívar, 1898) (original combination Xistra tricristata sumatrana) is regarded as conspecific with L. contractus .
