  A new species and a new record of Zoicinae Lehtinen & Hippa, 1979 (Araneae: Lycosidae) from Sumatra Island, with notes on miniaturization in wolf spiders Abstract A new species of wolf spider, Zoica veloxilla sp. nov., from Sumatra (Indonesia) is described based on both sexes. Lysania pygmaea Thorell, 1890 is recorded from Sumatra for the first time, and its male is illustrated and redescribed. A distribution map for Zoica and Lysania is provided. The problem of miniaturization in wolf spiders is briefly discussed. Based on an analysis of the literature, 32 minute species of wolf spiders in four subfamilies and eleven genera have been reported. The smallest wolf spider known worldwide seems to be Zoica minuta (McKay, 1979) from Australia. Omelko, M.M. & Fomichev, A.A.

Sulfated Fucosyl-Guanosines: Understudied Compounds from Spider Venom

Abstract

Low molecular mass compounds are the least understood among the components of spider venom. Sulfated fucosyl-guanosines originally detected from Hololena curta McCook are unique and rarely found in nature. While their synthetic counterparts are widely used as antibiotics. The present work compiles the current knowledge of these molecules, exploring their potential biogenetic origin. Additional topics highlight biochemistry and their significance as natural products with potential for pharmaceutical developments.
