Holoplatys apressus is a species of jumping spider endemic to New Zealand.
Description Holoplatys apressus are small with an unusually flat body (Which has been attributed to their habitat preference of small spaces under bark) that is typically black-brown with grey hairs covering the body. Adult males may have longitudinal black stripes along their abdomen.Żabka, M. (1991b). Salticidae (Arachnida: Araneae) of Oriental, Australian and Pacific regions, V. Genus Holoplatys Simon, 1885. Records of the Australian Museum 43: 171–240.
Taxonomy Holoplatys apressus was first described as Salticus appresus in 1873.Powell, L. (1873). On the spiders of New Zealand. Part I. Genus Salticus. Transactions of the New Zealand Institute 5: 280–286 Independently, Raymond Comte de Dalmas described Holoplatys senilis in 1917.Dalmas, R. de (1917a). Araignées de Nouvelle-Zélande. Annales de la Société Entomologique de France 86: 317–430 In 2002, S. appresus was moved to the Holoplatys genus and H. senilis was recognized as a synonym.Żabka, M. & Pollard, S. (2002c). A check-list of Salticidae (Arachnida: Araneae) of New Zealand. Records of the Canterbury Museum 16: 73–82
Habitat Holoplatys apressus can be found under the bark of Manuka and Kanuka trees. Some individuals have been found under the bark of exotic Pinus radiata and on driftwood, which has been suggested to imply that the species could have rafted from Australia.
