This adult female Typhlobelus sp. (Trichomycteridae: Glanapteryginae) in ventral view (note mature eggs) was collected in April 2010. It is a still undescribed species from the rio Asita, a right-bank tributary of the middle Ventuari River in southern Venezuela. Typhlobellus are highly reduced catfishes that live within the sand of rivers flowing off of the Guiana and Brazilian shields. They have lost their eyes and their paired fins. This specimen was approximately 2 cm total length. Best viewed in HD.
