Maxillary palps of four articles; the first very small, but visible; articles 2, 3, 4 penicillate; last article transverse, with a lateral appendage, its internal apical angle being rounded, mute. Underside of head with transverse carina ending on each side below the eyes, but quite far from them, in a somewhat conical tubercle.
