Bungalotis borax Evans, 1952

( Fig. 22-23 , 92 , 126 )

Evans (1952) described B. borax based on a male type from French Guiana (Guyane) and additional material from there, British Guiana ( Guyana), and the lower Amazon (Fonte Boa, Ega, Pará) in northern Brazil. The species was subsequently recorded from Suriname (de Jong 1983). Records for Rondônia represent a substantial distributional extension. The two males (FW length = 28.5 mm, n = 1) of B. borax examined from Rondônia (April, October) are bright tawny on both dorsal wings. These have narrow brown outer margins and series of postmedial brown macules. The macule in the discal cell on the forewing is close to, but not contiguous with, the macule in CuA 1 -CuA 2, which is offset proximad from the rest of the postmedial macules. The costa of the hindwing is shaded with brown distad, but the base of cell Rs-M 1 is of ground color proximad. The venter is similar to the dorsum, but duller, and the margins are more broadly brown. The macules on both wings have dark tawny centers. Male genitalia ( Fig. 92 ) exhibit the distinctive short uncus and toothed sacculus as shown by Evans (1952). The differences in the configuration of the harpe between Evans’ (1952) illustration and that shown here may be individual variation or Evans’ depiction suffers from the same malady as many of his other illustrations of the genitalia of Bungalotis .
