Etymology.
From the type locality.
Biology.
The species was collected between 1575-2000 m in elevation, in montane shrublands and montane rainforest. Nests were located in rotten logs, under moss, in root mats.
Comments.
Pheidole manantenina sp. nov. is known from Parc National de Marojejy in Antsiranana and morphologically is most similar to parapatric and widespread P. sofia sp. nov. Majors of P. manantenina sp. nov. differ from P. sofia sp. nov. in medial part of frons with smooth to indistinctly rugofoveolate interspaces, lateral sides of frons with more irregular rugae, body brownish to dark orange, and promesonotum with reduced sculpture; minor workers can be separated based on more reduced sculpture on head, and mesosoma predominantly smooth with indistinct rugofoveolae.
