The antennse are inserted near to each other, a little below the middle; they resemble those in Chelipoda and are likewise five-jointed, the two basal joints are short, the third somewhat elongated, pointed ovate and compressed, it terminates with a long, two-jointed arista, the basal joint of which is very small. Epistoma very narrow, a little broadened downwards; jowls not developed. The clypeus is formed of two chitinous lists. Proboscis is short, stretched flownwards; labrum is strong, semitubular, as long as the proboscis; it is high at the insertion, curved a little downwards at the apex and three-pointed; hypopharynx is as long as labrum, with parallel sides, pointed, and not dilated at the apex; the maxillae are a little shorter, they are somewhat broad elliptical blades, bearing some hairs and terminating in some bristle-like pro- cesses; the maxillary palpi are one-jointed, club-shaped, and with some bristles. Labium has the labella relatively large, longer than the basal part and cleft to their base. Thorax is rectangular, not much arched above; prothorax is small, but distinctly seen as a neck- shaped part; metathorax small. The thoracic disc has a few uniserial dorsocentral bristles (two, or only one in each row; perhaps the anterior bristle, which is placed inwards to the humeri, does not belong here and in Chelipoda in reality to the dorsocentral bristles); no acrostichal bristles. A notopleural and a supraalar bristle present. Scutellum with two marginal bristles. Metapleura with a few bristles. Abdomen consists of eight segments, but in the male the last are more or less hidden. The exterior genitalia in the male are rather large; they are mainly constructed as in Chelipoda; the two last ab- dominal segments are lower than the others, the genitalia have a large, more or less compressed piece below and ab
