8 ?? (Paratypes): L = 0.49-0.56 mm; a =
30-34.5; b = 8.6-9.2; c = 15-20; V = 73-76; stylet
= 17.1-18.2 um.
Holotype (female): L = 0.56 mm; a = 34.1; b
= 8.9; c = 17.7; V = 76; stylet = 18.2 um.
Allotype (male): L = 0.55 mm; a = 47;
b = 9.5; c = 17.4; stylet = 16.1um; spicules = 16.1 um;
gubernaculums = 4.3 um.
Female: Body almost straight except near the tail
region, where it is slightly bent ventrally. Cuticle with fine striae.
Lateral field marked by 4 crenate incisures occupying ? body width.
Head region flattened, ½ as wide as high, bearing 3 distinct annules,
strongly sclerotized. Stylet 18.2 um in length with laterally
directed knobs. Shaft of spear 9.6 um. Orifice of the
dorsal oesophageal gland 4.3 um behind base of spear. Oesophagus
a pear shaped metacarpus more long than broad, and has well developed crescentic
valve plates. Posterior oesophageal gland lobe-like extending ventrally
over the intestine for about 4-4? body widths after the oesophageo-intestinal
junction. Excretory pore 89.9 um (79-89.9 um in paratypes)
from the anterior end, about one body-width below the nerve ring.
Hemizonid lies immediately above the excretory pore, and measures 2 um
in length. Vulva is a transverse slit. Ovary single, prodelphic
and outstretched. There is a small spherical Spermatheca; uterus
small and has quadri-collumella. Post-uterine vulval sac about 1
vulval body diameter in length. Tail cylindrical with an annulated
terminus, about 2-2½ times anal body diameter in length. Phasmids
are located in the posterior half of the tail. Tail with 17-20 annules.
Male: Testis single, outstretched with spermatocytes
in a single row. Spicules paired, arcuate, cephalate, 16.1 um
in length. Gubernaculum thin, rod-like, 4.3 um in length.
Bursa with a slightly crenate margin and envelops the tail completely.
It is supported by a pair of papillae. Phasmids located in the posterior
half of tail.
Type habitat: Soil around roots of Mentha arpensis
L. and Coriandrum sativum L.
Type locality: Saroornagar, Hyderabad (A.P.), India.
Type specimen: Holotype and Allotype slides deposited
in the Zoology Museum, Osmania University, Hyderabad (A.P.), India.
Diagnosis: This species comes close to P. fallax
Seinhorst, 1968 in the presence of 3 labial annules, 4 lateral incisures,
in having a crenate tail tip and in the presence of males and spermatheca
with sperms. It however, differs from P. fallax in being slender,
with a short oesophagus, long tail, long stylet and in the more posteriorly
placed vulva. It also differs from P. capitatus sp. n. in
the lip region, laterally directed stylet knobs, tail shape and position
of phasmids. It differs from P. singhi in being longer and
more slender, outstretched ovary, and longer cylindrical annulated tail.
It also differs from P. barkati sp. n. in being more slender, position
of the dorsal oesophageal gland orifice, position of hemizonid and possessing
an outstretched ovary.
