ABSTRACT
The whip spider genus Sarax Simon, 1892 is widely distributed throughout Southeast Asia and part of the Indo-Malayan region. The genus is recorded from several Indonesian islands, but no species are known from inside the area that comprises the biogeographical region of Wallacea, despite being recorded from both sides of the area. An expedition to survey the biology of caves in Timor-Leste (formerly East-Timor) discovered populations of amblypygids living underground and including a remarkable new species of Sarax, S. timorensis sp. n., the first Amblypygi known from the island of Timor. The new species is here described bears the unique character state of two pairs of lateral eyes, instead of three or none as in all other living species of Amblypygi, and expands the biogeographic range of the genus. New records of amblypygids are given for two caves in Timor-Leste. A detailed description and a discussion of its distribution and the species characters are also provided.

ABSTRACT
Iberoporus pluto sp. n., the first stygobiont beetle from Portugal (Dytiscidae, Hydroporinae), is described from a single female from the cave Soprador do Carvalho (Coimbra). The species is highly troglomorphic, depigmented, blind, and with elongated appendages not adapted for swimming. A molecular phylogeny based on a combination of three mitochondrial and two nuclear genes showed the new species to be sister to I. cermenius Castro & Delgado, 2001 from Córdoba (south of Spain), within the subtribe Siettitiina of the tribe Hydroporini. Both species are included in a clade with Siettitia avenionensis Guignot, 1925 (south of France) and Rhithrodytes agnus Foster, 1992 and R. argaensis Fery & Bilton, 1996 (north of Portugal), in turn sister to the rest of species of genus Rhithrodytes Bameul, 1989, in what is here considered the Siettitia group of genera. We resolve the paraphyly of Rhithrodytes by transferring the two Portuguese species to Iberoporus Castro & Delgado, 2001, I. agnus (Foster, 1992), comb. n. and I. argaensis (Fery & Bilton, 1996), comb. n.
