Morphology and Anatomy:


Meloidogyne thailandica is distinguished from other species of the genus by various combinations of the following characters:

length of body, tail and tail hyaline region
shape of head
perineal pattern
stylet length and shape of stylet knobs in females
tail and tail terminus of second-stage juveniles
stylet length and shape of spicules in males
The perineal pattern is oval to rectangular, with smooth to moderately wavy and coarse striae, and with characteristic radial structures present underneath the pattern area.
The dorsal arch is high, sometimes round to rectangular, and striae in and around the anal area form a thick network-like pattern interrupted by lateral lines and large phasmids.

Molecular data from the ribosomal large subunit D3 expansion segment revealed four haplotypes, two of which were unique and distinguish M. thailandica  from M. arenaria, M. incognita, and M. javanica.

Intercepted in roots of ginger (Zingiber sp.) imported into USA from Thailand, so Thailand is assumed to be an area of distribution. The plants were imported to San Francisco after purchase at a Bangkok market supplied by local nursery growers.
