Description of Mesocriconema ericaceum n. sp. (Nematoda: Criconematidae) and notes on other nematode species discovered in an ericaceous heath bald community in Great Smoky Mountains National Park, USA

Abstract: A new species of Mesocriconema and a unique assemblage of plant-parasitic nematodes was discovered in a heath bald atop Brushy Mountain in Great Smoky Mountains National Park. Mesocriconema ericaceum n. sp., a species with males, superficially resembles M. xenoplax. DNA barcoding with the mitochondrial COI gene provided evidence of the new species as a distinct lineage. SEM revealed significant variability in arrangement of labial submedian lobes, plates, and anterior and posterior annuli. Three other nematode… Show more

“…The newly obtained sequences for each gene were aligned using ClustalX 1.83 with default parameters with corresponding published gene sequences of criconematids and related genera (Subbotin et al, 2005(Subbotin et al, , 2006Powers et al, 2010Powers et al, , 2014Powers et al, , 2016aVan den Berg et al, 2012;Maria et al, 2018a). Outgroup taxa for each dataset were chosen according to the results of previously published data (Subbotin et al, 2005(Subbotin et al, , 2006.…”

“…The genus Mesocriconema has a large number of species, which are morphologically very close to each other. Powers et al (2016) distinguished 24 COI haplotype groups; only five of them corresponded to morphologically characterized species. The authors further noticed that it is not unexpected that additional sampling of Mesocriconema will continue to reveal cryptic species within Linnaean morphospecies; as these species have been described in the recent works (Powers et al, 2016;Olson et al, 2017).…”
