Abstract: 
Osteology of Zagros toothcarp, which is endemic to karum basin head tributaries in Chahar-Mahal-va-Bakhtiari province, for it being endemic and tiny, has not drawn any attention so far. In this study the superfacial skull bones including the skull roof, opercular series, suspensorium, jaws, and circumorbitals were examined. The skull roof consists of the nasals, frontals, sphenoid, pterotics, epiotics, exooccipitals, and supraoccipitals. The opercular series consist of opercles, subopercles, interopercles, and preopercles. The suspensorium consists of hyomandibulae, symplectics, quadrates, ectopterygoids, endopterygoids, and palatines. The upper jaw includes the premaxillae circumorbital bone found in this species is the lachrymal. This study shows that this species bears all the characteristics of the related order, family, and genus and in general it is similar to the other related species and like them lack the parietal and the metapterygoid.
