Popis: One new family, six new genera and six new species of laniatorean harvestmen (Arachnida: Opiliones: Laniatores) from the mid-Cretaceous (Cenomanian, ca. 99 Ma) Burmese amber of Northern Myanmar are described. Ellenbergellus tuberculatus gen. et sp. nov. is the first fossil assignable to the extant family Tithaeidae. Mesokanus oehmkuehnlei gen. et sp. nov. is the first fossil assignable to the newly described family Mesokanidae fam. nov. Biungulus xiai gen. et sp. nov. and Gigantocheles nilsi gen. et sp. nov. are referred to Epedanidae, a family previously recorded in Burmese amber. Protopyramidops nalae gen. et sp. nov. is the first fossil potentially assignable to the extant family Pyramidopidae. Finally, Palaeobeloniscus thilolebi gen. et sp. nov is the first fossil assignable to the extant family Beloniscidae. These records offer new mid-Cretaceous constraints for the origins of four modern families and suggest that the Burmese amber forests hosted a fairly diverse fauna of laniatorean harvestmen which mostly belonged to lineages still present in Southeast Asia today.
