The genus
Geraesta comprises spiders that vary from brightly coloured (pink, green, yellow) to dark brown or grey with a mottled appearance. Females and males measure 5 to 7 mm in total length, with males slightly smaller. The
carapace varies from semi-circular, ovoid to elongate, usually with simple erect setae, and eye tubercles are present. The
abdomen varies in shape from round to ovoid to elongate with distinct abdominal tubercles and frequently decorated with patterns. Legs frequently have series of strong spines on the tibiae and metatarsi of the anterior legs. They can easily be confused with
Borboropactus. ==Taxonomy==
