Urodacus uncinus is a species of scorpion in the family Urodacidae. It is endemic to the northern part of Western Australia. [1]

Description

Urodacus uncinus is morphologically indistinguishable from U. lunatus and examination of the male genitalia is required. [1]

Distribution and ecology

Urodacus uncinus is rare and is only known from 6 locations and 16 specimens in north-eastern Pilbara. It is known to occur in an area of around 12,000 km2 (4,633 sq mi). This number may not be accurate because of its potentially patchy distribution. That means the area may be under 10,000 km2 (3,861 sq mi). Species with such distributions are considered short-range endemic. [1]

Due to certain morphological features, it is thought to live a fossorial lifestyle. They may only live in creeks and drainage lines. [1]

Etymology

The specific epithet "uncinus" comes from Latin and means "hook". This refers to the aculeus (stinger) that is more strongly curved than what is usually seen in the genus. [1]
