In-Depth Information
Male 74
Mean body length is approximately 1.95
1.13 mm.
Capitulum: Basis capituli are dorsally approximately 1.45 times as broad as
long; cornua are elongately triangular, sharply pointed, approximately five-
eighths as long as the base of basis capituli. Palpi are broadly salient (leachi-
type), combined breadth 2.1
2. 63 mm, breadth 0.98
2.3 times breadth of basis capituli. Hypostome is
as long as or slightly longer than palpi; external profile is quite straight; dental
formula is 4/4, with denticles in sub-equal length files of eight to ten (mostly
nine).
Scutum: Scutum is 2.0
2.2 times as long as broad; margins are gradually
rounded. Lateral grooves are deep, distinct, extend to anterior one-fourth of scutal
length, enclose first festoon. Cervical grooves are narrow. Punctations are moder-
ately numerous, irregularly scattered and sized. Festoons number 11.
Legs: Coxa are each with spur short, small, broadly triangular, sub-equal,
extending slightly beyond posterior margin.
Female 74
Overall body length is 2.55
1.28 mm.
Capitulum: Basis capitulum is dorsally approximately 1.9 times as broad as
long; external margins are converging posteriorly; cornua are broadly triangular,
approximately one-fourth as long as the base of basis capitulum; porose areas are
elongate and oval, slightly tilted, moderate size, widely spaced. Palpi are similar to
those of male except as follows; segment II spur from posteroventral margin is
slightly shorter and broader; ventrointernal setae usually number seven. Segment
III is slightly longer, three setae from internoventral margin posteriorly.
Hypostome is essentially as in male.
Scutum: Scutum is about 1.25 times as long as broad. Cervical grooves and
punctations are essentially as in male. Genital operculum is sub-quadrate; margins
are straight; junctures are rounded.
2.85 mm, breadth 1.20
Nymph ( Figure 2.118 ) 74
Mean body length is approximately 1.3 mm, breadth 0.8 mm.
Capitulum: Basis capituli are dorsally approximately 2.8 times as broad as long,
external margins somewhat constricted posteriorly; cornua are triangular, approxi-
mately one-third as long as the base of basis capitulum. Palpi are broadly salient
posteriorly (leachi/doenitzi-type); combined breadth approximately 1.75 times that
of basis capitulum. Hypostome is as long as or slightly longer than palpi; dental
formula is 2/2, with denticles in files of about nine.
Scutum: Scutum length and breadth are approximately equal; greatest breadth is
near mid-length, margin thence gradually converging, posteriorly relatively short,
broadly rounded. Cervical grooves are as an arc, extending beyond scutal mid-
length. Punctations are few and small.
