A new genus of Holothyrina: Neothyridae (Arachnida, Anactinotrichida) from the Manaus area, Amazonas state, Brazil

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.

Gehring-Hayman theorem for conformal deformations

We study conformal deformations of a uniform space that satisfies the Ahlfors Q-regularity condition on balls of Whitney type. We verify the Gehring–Hayman Theorem by using a Whitney Covering of the space.
