TWO NEW SPECIES OF LIODESSUS GUIGNOT, 1939 DIVING BEETLES FROM NORTHERN PERU (COLEOPTERA, DYTISCIDAE, HYDROPORINAE)

Two new species of Liodessus Guignot, 1939 diving beetles from Northern Peru (Coleoptera, Dytiscidae, Hydroporinae)

The diving beetles Liodessus altoperuensis sp.nov.and Liodessus caxamarca sp.nov.(Dytiscidae, Hydroporinae, Bidessini) are described from the high altitudes of the Puna regions of north western Peru.They occur in shallow and exposed mossy peatland puddles.We Nightstand delineate the two species using structures such as male genitalia, beetle size,
