Belongs within: Assamiidae. The Irumuinae are an African subfamily of blind, subterranean harvestmen (Kauri 1985). Characters (from Kauri 1985): Second metatarsus divided into two or more segments. Number of segments in tarsus II reduced and in most cases fewer than in tarsus IV, or equal in number. Inner tubercle of lateral tubercle pair in anterior… Continue reading Irumuinae


Belongs within: Assamiidae. The Sidaminae are a group of assamiid harvestmen found in Africa with large ventral spines on the pedipalp. They have been distinguished from the Maruinae by the absence of a median spine on the anterior margin of the carapace (Kauri 1985) but the significance of this distinction is questionable. Characters (from Santos… Continue reading Sidaminae


Belongs within: Assamiidae. The Polycoryphinae are a group of assamiid harvestmen found in southern Asia and central and eastern Africa. They are characterised by the presence of chitinous projections concealing the spiracles, and of a frontal spine on the anterior margin of the carapace (Santos & Prieto 2010). Characters (from Santos & Prieto 2010): Anterior… Continue reading Polycoryphinae


Belongs within: Assamiidae. The Hypoxestinae are a subfamily of assamiid harvestmen found in Africa and Asia (Santos & Prieto 2010). They are generally characterised by the absence of characters found in other subfamilies and should be considered of questionable monophyly. Characters (from Santos & Prieto 2010): Anterior margin of carapace unarmed; spiracles visible, unprotected; femur… Continue reading Hypoxestinae


Belongs within: Assamiidae. The Trionyxellinae are a group of harvestmen found in southern Africa and Asia, characterised by the presence of a pseudonychium between the true claws.

Belongs within: Assamiidae. The Dampetrinae are a group of assamiid harvestmen found in south-east Asia and Australia (Roewer 1935). Characters (from Roewer 1935): Frontal margin of carapace unarmed, without median denticle. Palpal femur with ventral spines shorter than diameter of femur. Stigmata hidden by row of denticles on posterior margin of coxa IV. Telotarsus I… Continue reading Dampetrinae
