Is this a D'Arnaud's Barbet? There appears to be no red on the top of the upper tail coverts.

My other guess was Usambiro Barbet, the description in the book says it does not have red on the upper tail cover, but the picture in the book is such that you cannot see either the upper or lower tail covers. Any experience with Usambiro?

Well, short term you can choose the position of the world wide checklists (Clements and H&M) which do not split these as species ...

The best feature (of not calling) is the colour of the beak - black in Usamiro and horn in D'Arnauld's. Then Usambiro never has a black cap or bib (only adult male D'Arnauld's does, mind) and, yes, it has less red. I can't really see the bill in this picture too well, nor the head and certainly not the bib! But from what I can see it could be a black bill with a bit of shine and doesn't seem to have any black on the head (like a female/juv d'Arnaud's). THese, combined with range suggest it's probably Usambiro.
 
Do these pictures help, I did not chose this originally because it does not show the rump and is a little out of focus

Ah ha! The bill colour does vary slightly seasonally, with age and around the edge of the range. These look paler than some, but certainly not the pale horn on a breeding d'Arnauld's (I do think d'Arnauld's bills can be this grey too when not breeding, so it's a bit in between), but the two together clearly show a pair of Usambiro Barbets - male on the right. The emini race of d'Arnauld's is the one in southern Kenya and norther TZ and the male has a jet black cap and heavier bib. This, typical of Usambiro, shows a small black bib and no black cap at all.
