Systematic placement of the enigmatic genus Timesius Simon, 1879 (Opiliones, Laniatores, Nomoclastidae), with description of a new species from the Colombian Andes
Abstract
The enigmatic monotypic genus Timesius Simon, 1879, hitherto assigned to Stygnidae Simon, 1879, is redescribed
and its phylogenetic position inferred upon morphological and molecular evidence, resulting in its reallocation to the
family Nomoclastidae Roewer, 1943. The type material of Timesius vesicularis (Gervais, 1844), long presumed lost, was
rediscovered, and is hereby redescribed and illustrated. Also, a new species, Timesius paramuno sp. nov., is described
based on specimens collected in the Páramo ecosystem in the Central Cordillera, Colombia. Timesius vesicularis can
be readily distinguished by having two long spines on area III of the dorsal scutum (two short tubercles in T. paramuno
sp. nov.) and small whitish-yellow granules on the ocularium and dorsal scutum (vestigial whitish-yellow granules in T.
paramuno).
