Cataglyphis flavobrunnea

Identification
Sharaf et al. (2015) - The original description of C. flavobrunnea indicated differential diagnosis of this taxon with Cataglyphis laevior of the C. bicolor-group, diehlii-complex (Agosti, 1990). However, examination of the newly designated lectotype and the remaining 11 paratypes indicates that the species are very different. Cataglyphis flavobrunnea has a uniformly brownish body and yellowish gaster whereas C. laevior has yellowish brown body and dark brown gaster. The head and mesosoma of C. flavobrunnea has dense white pubescence, whereas C. laevior lacks pubescence on the head and mesosoma. Collingwood and Agosti (1996) mentioned that head C. flavobrunnea is smooth and polished, but the head of the Lectotype is dull and is finely granulate.
