REVISION OF GENUS ZAMARADA 27 



3 (2) Dorsal process of valve tapered apicad and tipped with a minute, claw-like 



spine; a very slender, acicular projection at about three-fourths. Fulcrum 



not extending to tip of aedeagus ........ 7 



- Dorsal process of valve rounded apicad, without minute spine at tip; 



projection at about three-fourths not finely acicular. Fulcrum extending 

 beyond tip of aedeagus .......... 4 



4 (3) Projection from three-fourths dorsal process twice as long as apical fourth of 



valve. Dilate apex of fulcrum coarsely spined ..... 5 



Dorsal process of valve slightly constricted at four-fifths with short 

 projection beyond, equal in length to slightly dilate apical fifth. Fulcrum 

 slender, apex finely scobinate ........ 6 



5 (4) Projection from about three-fourths dorsal process of valve spatulate, not 



tapered. Uncus strongly sclerotized and tapered, apical half one-fourth as wide 

 as basal half; dorsal and ventral surfaces compressed to form chisel-like tip. 

 Aedeagus with thorn-like lateral projection just below apex mesotaenia (p. 37) 

 Projection from about three-fourths dorsal process of valve tapered. Rounded 

 tip of evenly tapered uncus about one-third as wide as base. Apex of 

 aedeagus smoothly tapered, without projection . . . labrys (p. 36) 



6 (4) Dorsal processes on valves symmetrical ..... deceptrix (p. 38) 



- Dorsal processes on valves asymmetrical, basal half of process on left valve 



twice as broad as basal half of process on right valve . . delosis (p. 40) 



7 (3) Apex of fulcrum slender and minutely, but densely scobinate ... 8 



- Apex of fulcrum not scobinate, but weakly sclerotized and dilate to partially 



enfold ventral surface of aedeagus ....... 10 



8 (7) Apical third of uncus as slender as apical fourth of dorsal process on valve. 



Several short, thorn-like spines present at seven-ninths aedeagus 



latilimbata (p. 30) 



- Apical half of uncus stout, twice as broad as apical fourth of dorsal process 

 of valve, tip slightly dilate. Dorsal surface of aedeagus serrate in apical 

 third ............. 9 



9 (8) Vestiture and non-hyaline areas of wings predominantly pale grey mixed with 



dark grey ....... minimaria minimaria (p. 28) 



- Vestiture and non-hyaline areas of wings predominantly buff mixed with 



yellowish brown ....... minimaria arenosa (p. 29) 



10 (7) Acicular projection from five-sevenths dorsal process of valve one-third as 



long as apical two-sevenths of valve. Ventral plate of gnathus diamond- 

 shaped, about one-half as broad as base of uncus. Left side of aedeagus 

 coarsely serrate in apical third ..... townsendi (p. 31) 



- Acicular projection from two-thirds dorsal process of valve two-thirds as long 



as apical third of valve. Apical margin of ventral plate of gnathus broadly 

 rounded, the plate as broad as base of uncus. Aedeagus wholly smooth 



eurygnathus (p. 32) 



11 (1) Membranous valve with well-developed longitudinal, setose ridge parallel 



with dorsal margin. Apex of fulcrum curved through 180 degrees, tip 

 coarsely scobinate. Madagascar only . . . . . . . 12 



- Membranous valve with a setose longitudinal ridge very rarely developed. 



Fulcrum straight. Species not occurring in Madagascar . . . 13 



12 (11) Apex of uncus slenderly produced and curved ventrad. Dorsal margin of 



valve one-half as long as aedeagus. Strongly sclerotized, scobinate tip of 

 fulcrum not extending to tip of aedeagus . . . griveaudi (p. 34) 



Uncus tapered to rounded apex. Dorsal margin of valve one-third as long 

 as aedeagus. Strongly sclerotized tip of fulcrum extending beyond tip 

 of aedeagus. ....... aureomarginata (p. 33)
