Abstract

A new species, Geraldius inserrai sp. n. collected from lichens and epiphytic plants growing on branches of trees in Mexico State, México, is described and illustrated.  Geraldius inserrai sp. n. is characterized by female body length = 1.0-1.2 mm, b = 4.3-5.1 and c = 8.5-15.3, lengths of pharynx = 215-247 μm, and pharyngeal corpus = 123-143 μm, distance between the phasmid and anus = 33-50 μm and presence of a single pair of dorsal post-cloacal papillae at the end of the tail. An identification key is provided for the species of Geraldius Sanwal, 1957.  Phylogenetic relationships of the representatives of the genus Geraldius with other related taxa are constructed using the D2-D3 of 28S rRNA gene sequences. The description of the genus is emended.
