Modigliani, NHRS (NRM-ORTH 0013047 + 0013046).   Notes.-   Bolivar(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.  Guenther(1935)synonymized Xistra tricristata var. sumatranawith  Paratettix contractuswithout giving details. According to  Guenther(1939), the specimens of  L. sumatranahave 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. contractusfrom Borneo, these undulations are weaker. Otte (1997)gave the subspecies a specific status based on occurrence on different islands (as in  L. tricristatusmentioned 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( Bolivar, 1898) (original combination  Xistra tricristata sumatrana) is regarded as conspecific with  L. contractus.
