)); 8 antennal articles, the 6th is the longest and the 8th is the shortest article with 4 sensory cones. The 6th antennal article commonly has 3–5 thick bacilliform sensilla among 12–20 sensilla. A row of minute backward-pointing setae is present along the posterior margin of the labrum. The lateral palp of the gnathochilarium is, with 9–11 conical sensilla, 1.25–1.5 times longer than the medial palp. Tergal trichomes are arranged in two latero-posterior groups with a marginal row separated by a central gap in the middle of tergites. A spine is present on tarsus 2. Tarsus 1 has a similar spine, but it is shorter and smaller in size. The anterior setiform process of the telotarsus is present and is less than half the size of the claw. Coxal glands are located on the 8th and 9th coxa in the male.
