In the nematode family Criconematidae, a taxonomy primarily based on cuticle characters has created classifications that are notoriously volatile. Molecular characters may lead to their stabilization. A phylogenetic tree of Criconematoidea was constructed using 166 new near full-length 18S rDNA sequences and 58 sequences from GenBank. Bayesian and maximum likelihood (ML) analyses produced trees...

Four new species of the genus Hemicriconemoides (H. californianus n.sp., H. taiwanensis n.sp., H. annulatus n. sp., and H. nitida n.sp.) are described. The range of total length of H. mangiferae is increased on the basis of specimens collected in Israel, Observations on H. mangiferae and H. litchi support the validity of H. litchi as distinct from H. mangiferae.

An abundant female population of a criconematid species identified as Mesocriconema kirjanovae (Andr ssy, 1962) Loof &De Grisse, 1989 is reported from a natural habitat in southeastern Spain. Measurements and morpho-anatomy obtained with light microscopy and scanning electron microscopy are included and compared with previous data on this species.

Bakernema dauniense n. sp., a bisexual species from the rhizosphere of Pinus halepensis Mill. in Italy, is described and illustrated. Primary differentiating characteristics of the female are body annules bearing short, membranous projections 1.4-2.2 mum long, an anterior vulval lip slightly overlapping the posterior, and a linearly arcuate vagina. The juvenile differs markedly from adults by h...

A 16.4-ha arca at the Michigan State University Water Quality Research Site was surveyed to obtain information on the habitats and prominence of taxa of the Criconematinae. Fifteen species representing six genera (Macroposthonia, Lobocriconema, Criconema, Crossonema, Nothocriconema, and Xenocriconemella) of this subfamily were recovered from the experimental site. Species occurrence and populat...
