It includes over 3,700 species distributed mainly in the tropics They are characterized by the male genitalia without musculature, operated by hydraulic pressure and by the double tarsal claws of posterior legs.

8-579: Is short and unsegmented (derived character state shared with the Dyspnoi). The penis is complex, with many sclerites . Some of the sclerites are movable, with a single penial muscle present. For the most part, the penis is without muscles, instead working by hemolymph pressure. Definitions and limits of superfamilies are still in a state of flux. The largest by far is the Gonyleptoidea, with over 2,000 described species. Distribution of subunits of Laniatores
12-456: Is the largest suborder of the arachnid order Opiliones with over 4,200 described species worldwide. The majority of the species are highly dependent on humid environments and usually correlated with tropical and temperate forest habitats. Laniatores are typically (relatively) short-legged, hard-plated, spiny Opiliones, common under logs and stones, in leaf litter and in caves . They often have spiny pedipalps and paired or branched claws on
16-461: The third and fourth pairs of legs. The largest family is Gonyleptidae Sundevall, 1833 , endemic of the Neotropics , with over 800 valid species and showing many cases of maternal and paternal care. The dorsal scutum consists of a single piece, with the carapace or peltidium entirely fused with abdominal scutum. The pedipalpus is usually robust and armed with strong spines. The ovipositor
