Description

Species of ''Dicranolasma'' range in body length from three to 6.4 mm. Most parts of the body are encrusted with soil particles. The anterior region features a large headlike "hood" with the eyes in center, which consists of two curved processes. The
chelicera The chelicerae () are the mouthparts of the subphylum Chelicerata, an arthropod group that includes arachnids, horseshoe crabs, and sea spiders. Commonly referred to as "jaws", chelicerae may be shaped as either articulated fangs, or similarly ...

pedipalp Pedipalps (commonly shortened to palps or palpi) are the second pair of appendages of chelicerates – a group of arthropods including spiders, scorpions, horseshoe crabs, and sea spiders. The pedipalps are lateral to the chelicerae ("jaws") and ...
s are both hidden under the hood in adults and about half as long as the body. The legs are short. Immature forms are quite different from adults. The immature form of ''D. opilionoides'' was even described as a different genus (''Amopaum''). The hood develops only gradually, so in young ''Dicranolasma'' the relatively longer pedipalps are carried outside the hood. (2007): Dicranolasmatidae Simon, 1879.
