title: Tylenchocriconema alleni n. g., n. sp. from Guatemala (Tylenchocriconematidae n. fam.; Tylenchocriconematidae n. superfam.; Nematoda).
abstract: Tylenchocriconema alleni n.g.n.sp, is described from soil about roots of a bromeliad from Guatemala City, Guatemala. It has characteristics of both the Tylenchoidea and Criconematoidea. Tylenchocriconematidae, n. fam., and Tylenchocriconematoidea, n. superfam., are proposed to express the relationship of this species to other taxa. Tylenchulidae and Paratylenchidae are considered closely related, and Tylenchulidoidea, n. rank, is proposed to indicate their relationship.
