Dyscophellus diaphorus (Mabille and Boullet, 1912)

( Fig. 34, 37 , 100 , 127 )

Males of D. diaphorus from Rondônia (mean FW length = 28.1 mm [27.2-28.9, n = 8]) vary from bright fulvous to red-brown with variable brown scaling on the margins. None are nearly as bright as the individual illustrated by Seitz (1907-1924). The macules on the ventral hindwing vary from all being entirely brown to all having white centers. Male genitalia of material from Rondônia ( Fig. 100 ) do not seem to differ from those illustrated by Evans (1952). A possible female of D. diaphorus from Costa Rica was discussed above under D. porcius .

Dyscophellus diaphorus is uncommon in central Rondônia, with records from June to August in the dry season ( Fig. 127 ). The species has been otherwise recorded in northern South America ( Evans 1952) .
