14mm. The facies is blackish brown as in the previous two species, but the species is smaller, and the forewing has an obscurely darker discal lunule and irregular antemedial and postmedial fasciae. The antemedial has some sparse pale blue irroration associated with it, and this is more evident in a broken, irregular submarginal fascia, and is evident also at the tornus of the hindwing, where three pale blue blocks enclose two darker ones along the distal part of the dorsum. The underside is a more uniform rich dark brown, with fragments of the pale submarginal evident. The legs are densely invested with velvety scales that are a dark rich brown, almost black. The first segment of the labial palps is shorter than in the other species, and the second curves gently back over the head and the thorax, with the much shorter, straight third segment just extending over the abdomen. The hair-scales within the labial palps are straw coloured as in microkalialis. The male genitalia are somewhat as in parvikalialis except the saccus is shorter, as is the saccular process. The aedeagus vesica extends more distally than laterally through a broad diverticulum, and lacks scobination.
