Dorsal view of male Melanopa grandis, from Zhang & Zhang (2013). Scale bar = 2 mm.

Belongs within: Sclerosomatidae.

Melanopa is a genus of sclerosomatid harvestmen known from southern and eastern Asia. It is characterised by the presence of a pseudoarticular nodule on femur I, a median spine on scute II, and femora I and III that are shorter than the body, but the monophyly of the genus as a whole is suspect (Zhang & Zhang 2013).

Characters (from Roewer 1955): Femora I–IV with 0.1.00 nodules; median spine(s) present on area 2 of scutum only or on both areas 1 and 2; eyemound dorsally smooth or granular, without larger, prominent, single spines; femora I and III cylindrical, shorter than body.
