Eyes separated by 2.3 – 2.4× their height. Malar space 0.8× height of eye. Labrum with 5 digits. Antenna 12-segmented, seven basal flagellomeres pectinate; branches slightly flattened, dorsal branch of F2 8.3 – 12.5× as long as broad, 8.3× as long as basal length and 0.8× as long as head height; F6 and F7 lobate and elongate; last flagellomeres not segmented (Fig. 13).
