Rotylenchulus reniformis
species of worm
Rotylenchulus reniformis, the reniform nematode, is a species of parasitic nematode of plants with a worldwide distribution in the tropical and subtropical regions.
Taxonomy
This nematode has a wide host range, infecting many species of plants around the world. It was first observed on the roots of cowpea in Hawaii, and was described as new species and new genus in 1940. Its specific epithet, reniformis, was inspired by the kidney shape of the adult female. There are now ten species classified in the genus, but R. reniformis is the only species of major economic importance to agriculture. Recent studies have demonstrated R. macrosoma is the sister species to R. reniformis.
Distribution and host range
R. reniformis has been reported from thousands of localities in the Americas, Africa, Europe, Asia, and Australia. It has a wide host range that includes fruit trees, lentil, cotton, pigeon pea, tea, tobacco, soybean, pineapple, banana, okra, coconut, cabbage, sweet potato, alfalfa, corn, asparagus, palm, cucumber, tomato, squash, cassava, radish, eggplant, guava, melon, chickpea, and ginger. Certain plants are considered to be non-hosts of the nematode, such as little barley, common barnyard grass, pangola grass, peppers, and some cultivars of black mustard, oat, spinach, and sugarcane.
Morphology
The reniform nematode has esophageal glands overlapping the intestine and a short stylet.
Begin with the source’s own compact description: “Rotylenchulus reniformis” is species of worm. The dossier treats that line as a proposition to test through Rotylenchulus, reniformis and species, not as a finished interpretation.
Why this record matters
The phrase “species of worm” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Dec 17, 2025. The linked authority identifier is Q7370726. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1940.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
