Rilaena triangularis is a species of the harvestman family Phalangiidae.[1] It is sometimes considered to be in the genus Paraplatybunus, in the subfamily .
Description[]
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, but was later renamed through recombination.[2]
Chemical defense[]
When disturbed the Rilaena triangularis uses a chemical defence by emitting a strong-smelling secretion.[1] This fluid contains 1,4-Benzoquinone, 1,4-Naphthoquinone and Caprylic acid.
Range[]
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[]
The species thrives in forests, floodplain forests and fens.[1][4][5]
