With sparse, erect pilosity (Fig. 41C, E View Figure 41 ). Colour. Yellow (Fig. 41C, E View Figure 41 ).
Biology.
The species was collected between 3-1343 m in elevation, in rainforest, littoral rainforest, montane rainforest, and occasionally beach vegetation on sandy soil. Nests were located in rotten logs and branches, and once in canopy.
Comments.
Pheidole annemariae is most similar to P. marieannae sp. nov. Majors workers. It differs from P. marieannae sp. nov. in presence of smooth notch on genae, inner and outer teeth closely spaced and connected by indistinct concavity, posterior mesonotum with distinct teeth-like projections, and longer propodeal spines. Minor workers. It differs from P. marieannae sp. nov. in presence of small but distinct mesonotal spines and katepisternum, anepisternum, and mesonotum never entirely smooth.
