Jumping spider (Holoplatys species) Crevice spider

Kingdom: Animalia 
Phylum: Arthropoda 
Class: Arachnida 
Order: Araneae 
Family: Salticidae 
Subfamily: Marpissinae
Tribe: Holoplatysini 
Genus: Holoplatys

Common name: Flattened Jumping Spider, Crevice spiders, Chink jumping spiders.

Holoplatys have a long, flat, oval cephalothorax, which is truncated anteriorly, and a long, flat, oval abdomen. They are often found under the bark of trees. These spiders exhibit a behaviour called thigmotaxis, an urge to have both upper and lower body surfaces in contact with something. In other words, they like to sidle into cracks. So if you pick one up, it will try and squeeze between your fingers. 

Photos below are of several spiders of the Holoplatys species found in New Zealand.
