Scytodes armata is a species of spitting spider in the family Scytodidae. It is endemic to Costa Rica.[1]

Taxonomy

The species was first described by Antonio Domingos Brescovit and Cristina Anne Rheims in 2001.[2] Prior to its formal description, specimens of S. armata had been misidentified as Scytodes championi by Valerio in 1981.[3]

The specific name armata refers to the strong ventral spines along the male's first and second pairs of legs.[2]

Distribution

S. armata is known from several localities in Costa Rica, including La Selva in Heredia Province, Cahuita in Limón Province, and Monteverde in Puntarenas Province.[2]

Description

Scytodes armata is a medium-sized spider with males reaching a total length of 4.38–5.50 mm and females 6.25–6.75 mm.[2]

Males have a yellow carapace with brown patterns and cream-colored abdomen with dark brown transverse stripes. The legs are yellow with brown longitudinal markings along the underside of the femora.[2]

The species can be distinguished from related spiders by several characteristics. Males have a distinctive double row of spines along the underside of both the first and second pairs of legs, and a tubular projection on the male reproductive structure (pedipalp). Females have rounded, mushroom-like reproductive structures and a straight posterior margin on the epigyne.[2]
