The Army Ant Aenictus exiguus Clark a Synonym. 
The description and figure of Aenictus exiguus Clark, 
1934, Mem. Nat. Mus. Viet., Melbourne, 8:21, pi. 2, fig. 1, 
worker (type loc. : Cairns district, northern Queensland) 
agree well enough with samples from Queensland, New 
South Wales, and New Guinea of Aenictus turneri Forel, 
1900, Ann. Soc. Ent. Belg., 44: 75, worker (type loc.: 
Mackay, Queensland), except for the low measurement 
(“1.7 mm.”) given by Clark for his types. This measure- 
ment, like others that have been checked from Clark’s ant 
descriptions, appears to be excessively small, even for 
such a size-variable species as turneri. Particular similar- 
ities in the critical characters of head and mandible form, 
and shape of propodeum and ventral process of petiole, 
all indicate that Ae. exiguus must be considered a new 
synonym of Ae. turneri. Brown, 1952, Psyche, 58: 123, 
had already placed Ae. deuqueti Crawley as a synonym of 
Ae. turneri after examining type material. — W. L. BROWN,
