This species is definitely known from only a single (incomplete) specimen from one location. It is reasonable to assume that it is endemic to the Nechisar Plains, and hence is treated as Vulnerable owing to this small range and the potential threat to the habitat from over-exploitation by local people. However, it remains extremely poorly known and further information is needed to validate this evaluation.

Only known from one specimen (of which only one wing was collected), therefore overall appearance uncertain, but likely to look dark, relatively unmarked and similar to female Pennant-winged Nightjar Macrodipteryx vexillarius. The specimen had white tips to at least the outer two tail feathers, a rounded wing, with the wing-coverts marked with large buff spots, and a broad buffish-white band, almost midway along the outerwing, across the four outer primaries (and on the inner web only of the outermost primary). The key point is that the patch lies exceptionally far up the wing (i.e. towards the carpal joint), especially relative to the (strong and easily seen) emargination in the outer primaries (especially P9, the last-but-one). The voice is unknown.
