Carebara dentata is a dimorphic species and is widespread in Shivalik range of North-western Himalaya.
Identification
Bharti & Kumar (2013) - In some of the major workers the frons anterior to occiput is longitudinally rugulose. However, C. dentata resembles Carebara rectidorsa (Xu, 2003), but can be easily distinguished by the combination of following features: head anteriorly and posteriorly equally broader, eyes with a single ommatidium, anterior clypeal margin prominently concave, propodeum with posterodorsal corners bluntly angled, postpetiole broader than petiole in dorsal view (PTW 0.13mm, PPTW 0.18mm), body large in size (TL 2.42mm), while in C. rectidorsa head narrowed forward, eyes with two facet, anterior clypeal margin weakly concave, propodeal posterodorsal corners prominently rounded, postpetiolar and petiolar node equally broader (PTW 0.10mm), body smaller in size (TL 1.7mm).
