LEHTINEN, Pekka T.. A new genus of Holothyrina: Neothyridae (Arachnida, Anactinotrichida) from the Manaus area, Amazonas state, Brazil. Acta Amaz. [online]. 1999, vol.29, n.2, pp.325-330. ISSN 0044-5967.

A new genus of Neothyridae, type species Diplothyrus schubarti sp. n., is described from the leaf litter of a primary forest in the Reserva Florestal Adolpho Ducke, Manaus, Amazonas, Brazil. The two pairs of lateral excretory orifices instead of a single one in the type genus Neothyrus of the family Neothyridae, are diagnostic. A protonymph of Neothyrus ana Lehtinen, 1981, is also described as the first known nymphal stage of this family.

Keywords : Holothyrina; Neothyridae; Amazonas; new genus.
