Morphological and molecular analyses of plant
parasitic nematodes (PPN) from 12 sugarcane plantation sites of Tanganyika Planting Company (TPC) Limited in Kilimanjaro region of Tanzania revealed the presence of six PPN genera, i.e.
,
,
,
,
, and
. The genera with the highest densities and present in virtually all samples were
and
, and the most important species appeared to be
,
,
, and
. A total sequences of 11 partial ITS, 15 D2-D3 of 28S, and 6 partial 18S of rRNA gene, and 7 partial
gene of mtDNA of these species were obtained in this study. Morphology and molecular data comparisons between the Tanzanian
and the South African
indicated that
is a cryptic species complex. Based on the results of morphological and molecular analyses of
and
from China, Haiti, Indonesia, Iran, Niger and the USA,
syn. n. is proposed as a junior synonym of
