Culex (Culex) scutatus Rozeboom and Komp, 1948, p. 396. [New synonymy.] 
Systematics.—In the original description by Lane (1936) this spe- 
cies was assigned to the subgenus Microculer. Subsequently in his 
monograph, Lane (1953) placed the species in the subgenus Culez. 
Forattini (pers. comm., 1963) re-examined the holotype male and paratype 
larvae and discovered that the larval paratypes are actually members 
of the subgenus Microculex and that the holotype male properly be- 
longs in the subgenus Culez.
