Genus Corticattus new genus

Type species: Corticattus latus Zhang & Maddison , sp. nov.

Etymology. The generic name is from the combination of cortex (bark) and attus (a common ending for salticid genera), referring to the habitat of the spiders; masculine in gender.

Diagnosis. Small tree trunk dwelling spiders. Body is flattened. Chelicera has one bicuspid promarginal tooth and one unident retromarginal tooth. First pair of legs in male sometimes are widened. Embolus is long and coiled. Tegulum has distinctive proximal lobe and small distal triangular projection. Epigynum has window with a median septum. Corticattus is similar to the marpissoids Balmaceda (see Edwards 2006) and Metacyrba (see Edwards 2006) in the body form, but can be easily distinguished by the genitalia. Corticattus differs from other euophryine genera by the flattened body, the absence of retrolateral sperm duct loop and the presence of prolateral sperm duct loop on the bulb, the presence of a triangular projection at the distal end of the tegulum, and the presence of a large accessory gland on the copulatory duct.
