对新热带区的Laccophilinae属LaccodytesRegimbart，1895进行了重新定义和修订。我们发现了10个物种，其中6个被描述为新物种。我们定义了两个种组：Lacodytesapalodes-group（L. apalodes Guignot，1955，L. Rondonia sp.n.），和L.类趾甲组（L. americanus Peschet，1919，L. obscuratus sp.n.，L. bassignanii sp.n.，L. neblinae sp.n.，L. olibroides Regimbart，1895，L. phalacroides Regimbart，1895，L. takutuanus sp.n.，L. androginus sp.n.）。短小乳杆菌Laccophilus pumilio LeConte，1878，Young（1954）将其归为Laccodytes，属于一个未描述的属。Lacodytes物种是lotic和他们中的大多数栖息在南美洲的东北部，显然与委内瑞拉和圭亚那的多样性中心。描述，插图和扫描电镜照片的习性，生殖器和其他诊断功能提供了每个物种，连同栖息地说明，当已知的。我们提供了一个物种识别的检索表。
The Neotropical Laccophilinae genus Laccodytes Regimbart, 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 Regimbart, 1895, L. phalacroides Regimbart, 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.
