IOLA US (PHILIOLA US) Stempffer & Bennett 



Philiolaus Stempffer & Bennett, 1958 : 1336. Type-species : Iolaus parasilanus Rebel, 1914, 



by original designation. 

 Iolaus Hiibner (partim) ; Aurivillius, 1923 : 395. 



Eyes, palpi, antennae and legs as in Argiolans and Iolaphilus. 



Wing shape. Fore wing in 5* with inner margin weakly lobed ; hind wing as in Argiolans. 

 Male secondary sexual characters as in Argiolans and Iolaphilus. 



Venation identical with the same two subgenera. 



Male genitalia (Text-fig. 121, lateral view, Text-fig. 122). Of such a specialized type as to 

 warrant the erection of a subgenus ; uncus and tegumen almost completely separated from 

 the pseudotergum, which forms above them a kind of hood, a disposition more easily seen in a 

 lateral view, since the parts are superimposed when seen in postero-ventral aspect ; uncus 

 reduced to two small ribbons separated by a weak median depression ; subunci almost straight, 

 tapering to a sharp point ; tegumen very ample ; vinculum broad with a large pseudotergum ; 

 lower fultura very reduced ; valves roughly lozenge-shaped with a sharp digitate apex ; penis 

 elongate, slightly curved ; vesica enclosing three short spines ; uncus and lower margin of 

 valves pilose.
