  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.

Abstract
A new species of the genus Actinopus Perty, 1833, belonging to the cucutaensis group, is described from Colombia. The new species, Actinopus embera sp. nov., was discovered in the departments of Córdoba, Bolivar, Sucre, and Atlántico, located along Colombia’s Caribbean coast, and is readily distinguished by genital organ morphology. Additionally, we report a possible case of phoresis between a mite of the family Acaridae Latreille, 1802 and a female and three immature specimens of Actinopus embera sp. nov. from one of the type localities (Tiquisio, Bolí var). Finally, based on prior evidence and the events leading to the destruction of the type material, we propose Actinopus cucu taensis Mello-Leitão, 1941 as a species inquirenda.
