See text The Fissiphalliidae are a small monotypic neotropical family of harvestmen within the suborder Laniatores, superfamily Zalmoxoidea.

[1][3][4] The name of the type genus is combined from Latin fissus "split" and Ancient Greek phallos "penis".

[5] Fissiphallius are about two to three millimeters long, with legs ranging from three to almost nine mm.

The color ranges from yellowish to pale brownish, sometimes with stripes or dots.

[5] Fissiphallius have been found in Colombia (e.g. around Bogotá) at elevations of about 3,500 meters, and in lowlands of central and eastern Amazon Rainforest.
