In-Depth Information
Legs: Coxa are increasing in size from I to IV with small hook-like spurs.
Trochanters also show ridge-like outgrowths, bigger on trochanter IV.
Nymph ( Figures 2.122 and 2.123 )
The total body length is 1.5 mm; the body structure is more or less ovoid.
Capitulum: Capitulum is 0.29 mm long with no or very little cornua. Basis
capitulum is rectangular in shape and not showing any punctations. Palpi are
loosely arranged with moderate salience on palp II due to arrangements. Palp II
dorsally on the basal side bears a ridge-like outgrowth. On the ventral side palp II
shows two infrainternal setae, long and lanceolate and well spaced. Palp III on ven-
tral side shows a small outgrowth or spur. Hypostome is with 4/4 dental formula
and bearing nine to ten denticles per file.
Scutum: Scutum is wider and flat. The cervical grooves are deep, less convex,
and are two-thirds of total scutum length. Punctations are very rare. Festoons are
moderately marked and approximately equal in length and breadth. Body is little
less hairy as compared to adults.
Legs: Coxa increase in size from I to IV with small ridge-like spurs.
Larva ( Figures 2.122 and 2.123 )
The body is oval in shape and is 0.9 mm long.
Capitulum: Capitulum is loosely arranged, with an extraordinarily long hypo-
stome, almost double the total length of palps. The length of capitulum from tip of
hypostome to base is 0.23 mm. Basis capitulum is rectangular in shape with no
punctations and cornua. Palpi show no salience. Palpal segment II is dorsobasally
ridged, showing single infrainternal seta on ventral side. Palpal segment III shows
no spur on dorsal or ventral side. Hypostome is quite long measuring about 0.1 mm
in length with 3/3 dental formula and seven to eight denticles per file.
Scutum: Scutum is more or less triangular in structure. Cervical grooves are
moderately marked, reaching up to half of the scutum or little more. Festoons are
very superficially marked and are as wide as long. Body is less hairy.
Legs: No coxa show any spur but a small ridge-like outgrowth on coxa I is
present.
Species Relationship
This species differs from other Herpetobian species by having the following points:
1. A widely triangular dorsobasal spur on palpal segment II
2. Seven infrainternal setae in both sexes
3. Leathery body in female
4. Bigger and circular porose area
5. Broader hypostome
6. Surface of basis capitulum has more punctuations
