A REVIEW OF THE PASSANDRIDAE OF THE WORLD (COLEOPTERA, CUCUJOIDEA) .4. GENUS ANCISTRIA

The genus Ancistria is revised to include 32 valid species, 14 of whic h are described as new. One genus, 3 subgenera, 15 species and 1 varie ty are synonymised, and 1 primary junior homonym at species group leve l is replaced by a new name. The species are diagnosed with external m orphological, genital and meristic characters, keyed and illustrated. Ancistria is restricted to the Old World where it is most speciose in the tropics. Ancistria retusa (Fabricius), the only common species, ha s a distribution almost congruent with that of the genus; the other sp ecies are much more restricted. The biogeographical relationships are briefly discussed.
