Rilaena triangularis is a species of the harvestman family Phalangiidae.[1] It is sometimes considered to be in the genus Paraplatybunus, in the subfamily Platybuninae.
Description
[edit]Rilaena triangularis is a harvestman that lives across Europe. This species was first described by Johann Friedrich Wilhelm Herbst in 1799, initially as Phalangium triangularis. It was later renamed through recombination.[2]
Chemical defense
[edit]When disturbed, Rilaena triangularis emits a strong-smelling secretion as a chemical defense.[1] This fluid contains 1,4-benzoquinone, 1,4-naphthoquinone and caprylic acid.
Range
[edit]Occurrences of Rilaena triangularis have been recorded and aggregated in GBIF across Europe, with the exception of Spain and Portugal. It has also been observed in north-west and north-east corners of the United States.[3][1]
Habitat
[edit]The species thrives in forests, floodplain forests and fens.[1][4][5]
