Brown — Strumigenys 
241 
Distribution : Amazon Basin ; exact type locality unknown. 
14. Strumigenys cordovensis Mayr, 1887 (Figs. 25, 26, 27) 
Brown, 1958a: 218-220, fig. IB, E, F, G, worker, variation, distribution. 
Distribution : Southern Mexico to Trinidad and the Guianas. 
15. Strumigenys mokensis Forel, 1905 
Brown, 1958a: 221, raised from variety to provisional species rank. 
This is a very doubtful form, most likely a synonym of cordovensis. 
The whereabouts of the type is unknown. The species is not included 
in the key. 
Distribution : La Moka, Venezuela, type locality.

series.

Brown, 1957: 97-99, worker. 
New record: Xaxim, Santa Catarina (F. Plaumann leg.).

from types only. 
Group of tococae 
19. Strumigenys tococae Wheeler. 1929 
Brown, 1957: 101-102, fig. lc, worker. 
Biology: The types were taken from an abundant population inhab- 
iting the foliar sacs of Tococa formicaria, a tall myrmecophytic shrub, 
in the outskirts of Bffem. From this circumstance and the large size 
of the eyes, S. tococae is judged to be an arboreal or subarboreal special- 
ist. 
Distribution : Belem, Brazil, at the mouth of the Amazon ; known 
only from the type series. 
20. Strumigenys fairchildi Brown, 1961 
Brown, 1961: 60-61, worker. 
This species, described from a single worker, is very close to S. 
tococae , but differs markedly in gastric sculpture and pilosity. It is-
