Table 2 Crystallomorpha sumatrensis Rehn, 1909: 209 . N. vittatus Chopard 1968 12: 352. Nisitrus sumatrensis Otte 1994: 67 . — Cigliano et al. 2020 ( Orthoptera Species File online). Material examined Holotype INDONESIA Sumatra ; R. Weber leg.; AMNH . Type locality Indonesia : Sumatra . Remarks Based on the study of the type from Sumatra , we consider N. sumatrensis as a junior synonym of N. insignis , even though the colour pattern of the types of both species is slightly different. After the examination of the material from Sumatra identified “ N. sumatrensis ” and “ N. insignis ”, we observed that the colour patterns form a continuum between a lighter version in N. insignis and the darker, more contrasting specimens previously identified as in the type of N. sumatrensis . There are also little diagnostic differences in the male and female genitalia for both series.
