In this contribution we describe a new species of Exechopsis Millidge, 1991 from the State of Amazonas, based on both males and females. The male of Meioneta adami Millidge, 1991 is described for the first time. Mermessus conjunctus (Millidge, 1991), Novafrontina uncata (F. O. Pickard-Cambridge, 1902), Sphecozone fastibilis (Keyserling, 1886), Sphecozone ignigena (Keyserling, 1886) and Vesicapalpus simplex Millidge, 1991 are recorded for the first time from Amazonas. Sphecozone crassa (Millidge, 1991) are presented additional record from Amazonas. KEY WORDS. North of Brazil; Neotropical Region; complementary descriptions; spider taxonomy. The Linyphiidae consists mainly of very small spiders, Millidge, 1991. Additional records of Sphecozone crassa (Millidge, which are sheetweb builders (ROBERTS 1987, DRANEY & BUCKLE 1991) are presented. 2005, MILLER 2007). The presence of a discrete, intersegmental paracymbium (rarely missing); stridulatory striae file on the MATERIAL AND METHODS ectal side of the chelicerae; and autospasy of the legs at the patella-tibia junction distinguish this family from all others, All specimens examined and studied herein are depos- except Pimoidae (DRANEY & BUCKLE 2005).
