Description of Tylenchorhynchus thermophilus n. sp. (Nematoda: Tylenchina) from Saltgrass in Death Valley, California
Abstract
A stunt nematode, Tylenchorhynchus thermophilus n. sp., is described and illustrated from soil collected around roots of saltgrass (Distichlis spicata) in Death Valley, California. It is distinguished from the similar species, T. ewingi, T. raexicanus, and T. mashoodi, in having a longer female body, longer tail with more annules, and larger phasmids. Physical and chemical analysis of soil from saltgrass roots showed it to consist of 71% sand and possess high salinity (salt content of 0.51%) and a pH of 9.3. Key words: California, Death Valley, Distichlis spicata, morphology, new species, sahgrass, stunt nematode, taxonomy, temperature, Tylenchorhynchus ewingi, T. mashoodi, T. mexicanus, T. thermophilus.Downloads
