Measurements (from Loof, 1960)
L = 529 um; a = 23.7; b = 6.8; c = 19.0; V = 80.1
L = 480 um; a = 27.4; b = 6.5; c = 19.1; T = 48

Description (from Loof, 1960)
    Body rather slender in young females, fat in old ones.  Cuticular annulation fairly conspicuous.  Lateral field distinct, normally with 4-5, occasionally with 6 incisures.
    Female: In young specimens the ovary extends over one-quarter of body length, in old ones over more than one-half.  Spermatheca broadly oval to nearly round.  Posterior uterine branch variable in length, sometimes reaching 50 um.  In about 20% of the females examined (especially older ones) it carried a distinct rudimentary ovary.  Tail tapering slightly, its length in young specimens 2-2.5 X, in old ones 1.5-2 X anal body diameter; tip broadly rounded, truncate or indented; in some specimens appearing weakly and irregularly annulated.
    Intra-uterine eggs often contain embryos, as was noted already by Cobb (1920).
    Male: Spicula very slender, shaft ventrally concave.  Gonad extends over about one-half body length.  Testis shorter than vas deferens.  Bursal edge faintly crenate.
    This species may be distinguished from P. loosi by the more prominent cuticular annulation, the slightly more anterior position of the vulva, the shape of the female tail, and perhaps by its shorter oesophagus and the length of the posterior uterine branch.
    Tylenchus (Chitinotylenchus) sp. W. Schneider, 1938, is probably identical with this species, as Schneider himself has already suggested.
    Distribution and host plants: A mainly tropical and subtropical species.  Reported from Indonesia (Java: coffee, Zimmermann, 1898; Bally & Reydon, 1931; bamboo, Bally & Reydon, 1931; Indigofera endecaphylla, Bally 7 Reydon; Sumatra; Potamogeton sp. and Nitella sp., W. Schneider, 1938); West Indies (bluggoe banana, Cobb, 1919; mahogany, Cobb, 1920); Central America (abaca, Taylor & Loegering, 1953); California (Vitis vinifera, Steiner, 1927); Brasil (Musa sp., Rahm, 1928 and 1929); Philippines (abaca, Taylor & Loegering, 1953) and Japan (potato and sweet potato, Yokoo, 1956).

Measurements (from Sher & Allen, 1953)
L = 0.45-0.70 mm; a = 25-35; b = 5-7; c = 17-22; V = 76-83; spear = 15-18 um
L = 0.45-0.70; a = 26-40; b = 6-7; c = 17-24; T = 45-52; spear = 15-17 um

Description  (from Sher & Allen, 1953)
    Female: Lateral field marked by four incisures.  Lip region slightly set off from body, rounded, bears two annules.  Outer margins of heavily sclerotized labial framework extend into body about one body annule.  Spear-guiding apparatus extends posteriorly from basal plate about three annules.  Spear 18 um long, well developed, broadly rounded basal knobs.  Dorsal esopheageal gland orifice about 2 um behind spear base.  Hemizonid just anterior to excretory pore, about two body annules long.  Ovary does not extend to esophageal gland, consisting of a single row of oocytes, except for double row near anterior end.  Spermatheca oval.  Cellular oviduct long, uterus short.  Posterior uterine branch about one and a half times width of body at vulva.  Phasmid slightly posterior to middle of tail.  Four lateral lines extend past phasmid.  Tail tapering, terminus rounded.  No striations around terminus.
    Male: Similar to female.  Single outstretched testis does not extend to esophageal glands, spermatocytes in single or multiple rows.  Phasmids slightly posterior to middle of tail, extend slightly into bursa.
Type host: Roots of coffee.
Type locality: Bangor, Indonesia.

Description (from Bajaj and Bhatti, 1984)
 Female: head region low with two annules.  Lateral lines four, outer ones crenate, six in one specimen and areolated.  Spermatheca variable in size, always rounded or broadly rounded, usually full of sperm.  Tail elongated conoid with 21-32 annules, tail tip smooth, variable in shape, being flat or rounded, bifid, and may bear one or more mucro-like projections.
 Male: Abundant.
Type Host and Locality: Collected from soil around the roots of citrus orchards of Sirsa district.

Description (from Roman, Hirschmann, 1969)
Females: Lateral field often marked by four incisures, but may exhibit variations.  Some specimens with punctations scattered in outer bands.  Lip region slightly set off from body, bearing two annules.  Some specimens with two annules on one side and three annules on the other.  Anterior end of vestibule with slight refractive "ornamentation."  Stylet knobs round to oblong, showing much reduction in width in some specimens.  Glandular lobe of esophagus overlapping anterior end of intestine ventrally and slightly laterally.  Hemizonid two to three annules long, located immediately in front of excretory pore.  Gonad 108.0 to 313.2 um long.  Spermatotheca oval to round, usually containing spermatozoa.  Postvulvar uterine branch 18.0 to 36.0 um long.  Tail terminus rounded and smooth, little variation in shape.
 Males: Similar to females.  Stylet knobs variable in shape, frequently showing considerable reduction in width.  Hemizonid two to three annules long, located immediately, or one annule in front of excretory ore.  Gonad measuring 186.0 to 356.0 um.
