    Research output: Contribution to journalArticle

    Abstract

    The widespread halophilic genus Paraliochthonius Beier is recordedfrom Australasia for the first time, and two new species are recorded: P.darwini from tropical northern Australia and P. vachoni from New Caledonia.Paraliochthonius darwini is based upon several adults and a tritonymph,whilst P. vachoni is based on a male and a tritonymph. A key to the speciesof Paraliochthonius is presented, and the taxonomic status of P. insulae Hoff(from Jamaica), P. puertoricensis Muchmore (from Puerto Rico), P. johnstoni(Chamberlin) (from Mexico) and P. mexicanus Muchmore (from Mexico) isassessed, with Paraliochthonius mexicanus being removed from synonymy withP. johnstoni and regarded as a distinct species. New terms are proposed for twomorphologies of the chelal teeth: diastemodentate for teeth in which a gap ispresent between adjacent teeth, and juxtadentate for teeth that are abuttingeach other.
