In-Depth Information
Posterodorsal and posteroventral spurs on palpal segment III are prominent and medium
sized; present in mid-line and overlapping about one-third of segment II ventrally and up
to mid-length dorsally; infrainternal setae are long, lanceolate, and number five; puncta-
tions are few, small, and irregularly scattered; coxal spurs are blunt or ridge-like except
spur of coxa I where it is long...................................................................[H. bispinosa]

Spurs on palpal segment III are either reduced/blunt or have been placed toward internal
position; posteroventral spur when present is in middle or internal side; infrainternal
setae are short and feathery; coxal spurs are much reduced and moderate to small in
size...................................................................................................[8]
8.
Dorsobasal and dorsoventral spurs on palpal segment III are short and widely triangular;
infrainternal setae are short, feathery, and number six; lateral grooves are very short,
reaching to apical margin level of coxa IV, enclosing first festoon on both sides; coxal
spurs are very short, broadly triangular, and sharply pointed...................[H. kinneari]
Spurs on palpal segment III are reduced and blunt, overlapping half of the palpal seg-
ment II ventrally and just crossing the suture dorsally; infrainternal setae are very short
and number four; lateral grooves are absent; punctations are rare; coxal spurs are short
and broadly triangular...................................................[H. hystricis]
The palpi are compact and give triangular shape to capitulum; the posterodorsal and pos-
teroventral spur of palpal segment III are conventionally triangular and pointed but lying
on inner side of the palpi; infrainternal setae number eight and are feathery, closely spaced;
spurs on coxa are small; coxa I and IV spurs are triangular and pointed, while coxa II and
III spurs are rounded or ridge-like...........................................[H. wellingtoni]
Posterodorsal spur of palpal segment III is short and toward internal margin, while the
posteroventral spur is heavy, gradually tapered, and extending to the base of palpal seg-
ment II and in mid-line; punctations are numerous, large, and scattered all over the scu-
tum; infrainternal setae number seven, are feathery, and closely placed; coxal spurs are
robust or blunt; coxa I is with a long spur, while coxa II to IV are with ridge-like small
spurs...................................................[H. intermedia]
Posterodorsal spur of palpal segment III is short, triangular, and toward inner margin,
while the posteroventral spur is in mid-line but moderate and reaching to the mid-line of
palpal segment II; punctations are small and medium size and relatively few; infrainter-
nal setae number five, are long, lanceolate, and well spaced; coxal spurs are small; coxa
I spur is moderate, while other spurs on coxa are small or obsolete...................
[H. sambar]
Dorsobasal spur is obsolete; ventrobasal spur extends to half or more of segment II;
infrainternal setae number eight to nine and are very short, feathery, and closely spaced;
coxal spurs are moderate; coxa I spur is moderate and conventionally triangular, while
other coxa spurs are small...................................................................[H. kutchensis]
9.
Small ridge-like spur or elevation of dorsobasal side of palpal segment III; in some cases
the posteroventral spur is large and elongate; ventrobasal spur is shorter; infrainternal
setae are shorter and feathery or lanceolate; coxal spurs are much shorter...................[10]
10.
Small ridge-like or crest like dorsobasal spur on palpal segment III; ventrobasal spur is
slender, extending up to half of palpal segment II; infrainternal setae number five, short
but thin and well spaced; punctations are shallow, numerous, and small; lateral grooves
are obsolete or very short and not enclosing any festoon; coxal spurs are triangular and
blunt; coxa I spur is narrowly elongate, while coxa II to IV spurs are broad and shorter
consecutively; trochanters I to IV ventrally show triangular spurs...................[H. turturis]
Posterodorsal spur of palpal segment III is ridge-like; salience is moderate due to up-
curved palpal segment II; infrainternal setae are seven to nine in number, closely placed,
