Diagnosis. In addition to the characters for the genus ( Short 2010), adult Hydrophilus (Dibolocelus) can be differen- tiated from those of Hydrophilus (s. str.) by a more convex and robust body shape; maxillary palps usually modified being generally longer, broadened and curved towards apex, sometimes inflated and curved at mid-length, with third palpomere with deep and wide ventral excavation or flat and slightly widened towards the apex; labial palp widely triangular and inflated, clavate or subparallel in shape, with or without setae on lateral margins; fifth protarsomere wide and longer than any of the previous ones, sometimes slightly flattened and with a ventral laminar expansion, never as large as those in Hydrophilus (s.str.); internal spur of anterior tibia flat, sub-rectangular or rounded, with straight or curved external margins, if sub-rectangular then it can be short or long with its apex straight, irregular or clearly bifid; abdominal ventrites 3 and 4 have slight to well-marked oval, glabrous area at mid-line, and ventrite 5 has a wide oblong or sub-triangular glabrous area; ventrites 3 to 5 slightly raised at midline, flattened or forming a keel, slightly projected above ventrite posterior margin.
