Antennal insertions exposed or concealed. Visible portion of procoxa globular or transverse with the trochantin concealed or at least partly exposed. Procoxal cavity externally open and internally closed. Mesocoxae contigous to separated by less than 0.4 X coxal width, with mesocoxal cavity laterally open. Tarsal formula 4-4-4 or 3-4-4 in all males. Number of ventrites 5 without ventrites connate. Body length 1.-3.7 mm. Ovate to oblong, slightly to strongly flattened, pubescent.

The cosmopolitan species Typhaea stercorea (last figure) is commonly confused with a number of other small brown, pubescent beetles, in families like Languriidae and Biphyllidae.
