Found over most of 'southern' Australia, 
distribution similar to A. gratus. Some of the 
samples from southern Western Australia are 
consistently larger than material from other regions 
of Australia. Brooks (1951) states males 6-7.2 mm 
long, females 6-6.9 mm long; Lansbury (1969) 
males 6.9-7.2 mm long, females 6.75-7.5 mm long; 
southwestern Australia series, males 6.7-7.8 mm 
long, females 6.8-7.7 mm long. Javanese type 7.5 
mm long. 
In Australia, A. thienemanni has not been found 
much further north than the Elkedra River, ca. 340 
km NE of Alice Springs. The rostral prong of male
