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 delineate Plant Based Protein the two species using structures such as male genitalia, beetle vibrating-masturbators size, shape and colour pattern.Mitochondrial Cox1 data were also generated, and revealed clusters congruent with morphological evidence.
Altogether fourteen Liodessus species are now known from the Andean region.
