Leiobunum blackwalli is a species of harvestman. It is found in Europe, but has been introduced to British Columbia in Canada and Seattle in the United States.[1]

Description

Leiobunum blackwalli grows to 6 mm in females and 4 mm in males.[2] The second pair of legs grow to 50mm.[2] Similar in appearance to L. rotundum, the abdomen is broader at the rear and the dark marking broader at the rear than the front with a sharper cutoff than L. rotundum, and the palps are pale.[2]

Distribution

This harvestman is widespread throughout Britain and Europe, though less common than L. rotundum.[2][3] As at 2023 this species was regarded as newly introduced to British Columbia in Canada and Seattle in the United States.[1]

Habitat

It is usually found in woods or damp places, and also in gardens.[2][4]
