Habitat : Tucuinan (Sierra de Santiago, Sta. Alia) . 



Typus : Mus. H. v. B. S ad Sa. de Santiago, Tucuman, 

 22ud July 1904. [L. Dinelli leg. No. 3239.] 



This perfectly distinct new species of Thamnophilus is 

 named after its discoverer, Mr. L. Dinelli, who has lately 

 sent to several European Museums a large number of 

 beautifully prepared bird-skins collected by him in different 

 parts of Tucuman. 



Th. dinellii is apparently allied to Th. gilvigaster Pelzeln, 

 otherwise called Th. maculatus Lafr. et D'Orb. (which name 

 cannot stand, as there is already a Th. maculatus Such, 

 identical with Th. guttatus Vieill.), but differs from it in 

 having a pale fulvous upper breast and a fulvous-white 

 throat, these parts being of a dark ashy-grey in Th. 

 gilvigaster. The sides of the body are of a jDale fulvous tint 

 in Th. dindlii, while they are of a deep orange-rufous in Th. 

 gilvigaster. The black of the pileum in Th. dinellii is more 

 restricted, not descending to the nape as in Th. gilvigaster, 

 and the front is greyish-ash, instead of being black. The 

 grey of the back and the sides of the neck are much lighter, 

 and the black spots on the upper back are only just indicated. 

 The white markings on the outer tail-feathers are also more 

 restricted. 



The female described above was collected by M. GL A. Baer 

 at Sta. Ana, Tucuman, 1350 metres, 25th November, 1902. 

 It differs in the same way from the female of Th. gilvigaster 

 in having a fulvous breast and a whitish throat, these parts 

 being ashy-gre} T in the female of Th. gilvigaster.
