Type-locality: Sarawak, Borneo (A. R. Wallace). 



Tandjong, S. E. Borneo (Fritz Suck). 



Two workers and two males from Kina Balu, N. Borneo, obtained 

 from Staudinger. The worker has the gaster distinctly striated at the 

 base. This character, not mentioned by Smith, nevertheless exists 

 in the type {teste W. F. Kirby) and is regarded by Emery as distinctive 

 of the species. 



*61a. Myrmicaria carinata subsp. gagatina, subsp. nov. 



Worker. Length 5.7 mm. 



The series of small angles formed by the lateral carmae of the meso- and 

 epinotum are somewhat more acute than in the topical form and the body is 

 much smoother and more shining. There are only a few delicate longitudinal 

 rugae on the head, some confined to the sides and just below and above the 

 eyes and some abbreviated and widely separated on the posterior portion of 

 the head. On the thorax the rugae are also finer, more regular and further 

 apart. The extreme base of the gaster is finely striated as in typical carinata.
