Preliminary study on the diversity of Orthoptera from Kuala Belalong Field Studies Centre, Brunei Darussalam, Borneo Author Tan, Ming Kai Author Abdul Wahab, Rodzay bin Haji text Journal of Orthoptera Research 2018 27 2 119 142 http://dx.doi.org/10.3897/jor.27.24152 journal article http://dx.doi.org/10.3897/jor.27.24152 1937-2426-2-119 2. Nisitrus vittatus (Haan, 1844) Fig. 8 E-H Remarks.- This species was found abundantly around the station at the forest edge. During the day, the males can be heard calling on plant foliage. We also observed them feeding on flowers ( Tan et al. 2017b ). We compared this species with other congeners from Malay Peninsula and Borneo with help from T. Robillard. Tentatively, we considered the specimens from Kuala Belalong as Nisitrus vittatus , which can also be found in Malay Peninsula and Sumatra ( Robillard and Tan 2013 ). There are some minor differences in acoustic and morphological characters between our Bornean specimens and those from other parts of Southeast Asia. We need more material from Borneo to better understand the species. Figure 8. Gryllidae : Eneopterinae : Cardiodactylus pelagus : A. Male; B. Female; C, D.
