Male genitalia. — Vinculum typical, as in other species, but rather 

 heavily sclerotized. 



Tegumen glabrous; lateral arm rather elongate and slender, strongly 

 narrowing to point of articulation with vinculum, dorsal margin 

 rather weakly sclerotized and sinuate, ventral margin well sclerotized 

 and sublinear; dorsal area of medium width, not separated along 

 meson. 



Harpe divided, ^vdth prominent costal process. Lateral aspect: 

 approximate apical two-fifths directed somewhat ventrad and con- 

 siderably narrower than basal three-fifths, basal three-fifths subUnear; 

 costa and sacculus indistinctly fused, comprising approximate basal 

 half of harpe, glabrous except for punctate and setose ventrocaudal 

 margin of sacculus, broadest in apical fifth, basal four-fifths with 

 dorsal and ventral margins sublinear and gradually converging basad 

 to broadly rounded basal extremity, dorsocaudal portion of costa 

 considerably expanded and giving rise to large costal process; costal 

 process arising from dorsobasal angle near base of cucullus, approxi- 

 mately four-fifths as long as cucullus and two-fifths as long as entire 

 harpe, sublinear, directed considerably ventrad, major portion closely 

 subparallel with dorsal margin of cucullus, small apical portion over- 

 lapping ectal surface of cucullus dorsad, dorsal and ventral margins 

 sinuate and subparallel, approximate dorsal third to half very heavily 

 sclerotized and becoming minutely spinose toward apex, ventral half 

 to two-thirds weakly sclerotized and minutely punctate, apical one- 

 sixth to one-fourth very densely and minutely spinose, apex weakly 

 expanded and evenly rounded; cucullus partially set off from costa 

 and sacculus by areas of reduced sclerotization, comprising approxi- 

 mate apical half of harpe, broadest in basal fifth, markedly constricted 

 ventrad immediately distad of basal fifth, apical three-fifths irregularly 

 expanding toward apex, basal third glabrous, apical two-thirds be- 

 coming increasingly punctate and setose ectad and entad toward 

 apex, margins sinuate, dorsal margin very heavily sclerotized in basal 

 three-fifths, ventral margin heavily sclerotized in basal two-fifths and 

 with or without apical half minutely dentate, apex rounded. 



TranstOla with arm elongate and slender, approximately three- 

 tenths as long as harpe, well sclerotized, glabrous, basal two-thirds 

 subparallel with dorsal margin of costa, apical third converging with 

 and underlapping costa, terminating acutely somewhat distad of 

 basal extremity of harpe. 



Uncus bifid. Dorsal aspect: base rather large, sub triangular, 

 rather indistinctly fused with tegumen, heavily punctate and setose; 

 lateral margins very heavily sclerotized, sublinear, gradually converg- 

 ing distad; angle of bifurcation rather narrow, rounded; furcae of 

 medium length and width, tubular, well sclerotized, slightly diverging
