This species is certainly very different from dyak and luciolae, but 

 seems to be closely related to Smith's notabilis described from the 

 island of Batjan. Judging from Smith's figure and description, 

 however, dusun has a smaller and longer head and more curved epinotal 

 spines. My specimen seems to be too small to be the soldier of 

 Emery's jcrox.

 Calyptomyrmex emeryi Forel, Mitth. Naturh. mus. Hamburg, 1901, 18, p. 51, 



Type-locality: Sarawak, Borneo (Haviland). 

 Female. Length 4.5 mm. 



Very similar to the worker. Thorax narrower than the head only slightly 

 longer than broad; mesonotum somewhat flattened above, subtriangular, 

 fully as broad as long; scutellum longitudinally impressed in the middle, 

 overhanging the extremely short, vertical epinotum. Both the mesonotum 

 and scutellum coarsely reticulate-rugose. Wings with well-developed discoidal 

 cell, large pterostigma and single cubital cell, the membranes uniformly 

 brownish hyaline, the veins and pterostigma darker brown. 



A single specimen from Kuching (John Hewitt), which has been 

 compared wdth a worker cotype in my collection.
