N2 - A new genus of the millipede family Pseudospirobolellidae, Siliquobolellus gen. nov., is described from limestone mountains inThailand, based on three new species, viz. Siliquobolellus amicusdraconis gen. et sp. nov. from Uthaithani Province, Siliquobolellusconstrictus gen. et sp. nov. from Prachuap Khiri Khan Province and Siliquobolellus prasankokae gen. et sp. nov. (type species)from Lampang Province. The descriptions are based on gonopod morphology and mitochondrial DNA data (COI barcodes). The COIbarcodes grouped the three new species in a well-supported Siliquobolellus gen. nov. clade. The mean interspecific COI sequencedivergence among the three new species was 12% (range: 8–15%). The mean intergeneric COI sequence divergence between Siliquobolellus gen. nov., Coxobolellus Pimvichai, Enghoff, Panha & Backeljau, 2020, and Pseudospirobolellus Carl, 1912 was 19%(range: 14–23%). Three conspicuous gonopodal synapomorphies differentiate Siliquobolellus gen. nov. from other pseudospirobollellid genera: (1) the telopodital part of the posterior gonopod forms a deep concavity, (2) the telopodite of the anterior gonopod isdirected distad and does not reach the tip of the coxal part of the anterior gonopod, and (3) the tip of the anterior gonopod coxa isnarrowed, curving mesad. As such, the monophyly of the new genus is well supported by both morphological and mitochondrialDNA data. A distribution map and an identification key to the species are provided.
