Comments.

Rajmohana and Veenakumari (2011) stated that the mesoscutellar spines of Dvivarnus punctatus differ from those of Gryonoides based on their location on the mesoscutellum. We agree, and more specifically, the mesoscutellar spines of Gryonoides proximally abut the axillula and are derived at least in part from striations of the scutoscutellar sulcus (Fig. 5 ) whereas those of Dvivarnus are derived entirely from the mesoscutellar disc (Fig. 6 ). Rajmohana and Veenakumari asserted that the presence of punctation throughout T3 is unique to D. agamades . This character is indeed rare among teleasines, but it may also be found in Trimorus (Fig. 4 ) and Xenomerus ( X. spinosus Mikó & Masner, X. comatus Mikó & Masner) ( Mikó et al 2007). The biogeographical records published by Rajmohana and Veekakumari (2011) led them to suggest that this species was limited to semi-arid habitats. A broader geographic sampling has revealed that this species also inhabits the tropical rainforests of Southeast Asia.
