Abstract

The Neotropical Laccophilinae genus Laccodytes Régimbart, 1895 is redefined and revised. We recognize ten species, six of which are described as new. We define two species groups: the Laccodytes apalodes-group (L. apalodes Guignot, 1955, L. rondonia sp.n.), and the L. phalacroides-group (L. americanus Peschet, 1919, L. obscuratus sp.n., L. bassignanii sp.n., L. neblinae sp.n., L. olibroides Régimbart, 1895, L. phalacroides Régimbart, 1895, L. takutuanus sp.n., L. androginus sp.n.). Laccophilus pumilio LeConte, 1878, assigned to Laccodytes by Young (1954), belongs to an undescribed genus. Laccodytes species are lotic and most of them inhabit the north-eastern part of South America, apparently with Venezuela and Guyana as centre of diversity. Descriptions, illustrations and SEM photos of habitus, genitals and other diagnostic features are provided for each species, together with habitat notes, when known. We provide a key for species identification.
