Remarks. This species is easily identified by its nearly cylindrical body shape, lack of proboscis, transverse grove, or rostral lobe, small mouth with well-developed, yet small in size mental disc, and by the presence of a pleated papilliferous fold (as described in Kullander & Fang, 2004) on the lower lip. It was encountered in a large variety of stream types throughout southern Bhutan. It was the most common species of Garra in the low-lying rivers of the plains, where it was common amongst the cobble in riffles and occasionally caught with a cast net in the pelagic zone. Garra annandalei was encountered in runs, riffles, and pools, but most commonly in runs and near the inlet and outlet of pools. They were frequently sampled in sympatry with Barilius , Neolissochilus , and Psilorhynchus . The reduced disc size and occasional pelagic encounters of G. annandalei suggests that this species may be more of a generalist than its benthic-obligate congeners.
