Laniatores
Laniatores is the largest suborder of the arachnid order Opiliones with over 4,000 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 the third and fourth pairs of legs.〔Pinto-da-Rocha ''et al.'' 2007: 17〕 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. == Identification== Dorsal scutum consisting in a single piece, carapace or peltidium entirely fused with abdominal scutum. Pedipalpus usually robust and armed with strong spines. Ovipositor short, unsegmented (derived character state shared with the Dyspnoi). Penis complex, with many sclerites, some movable, a single penial muscle present, but mostly the penis is without muscles, working by hemolymph pressure.
