Ventral spur of palpal segment III is broadly triangular, overlapping anterior one-third of
palpal segment II; coxal spurs are small and blunt, decreasing in size from coxa I to IV;
infrainternal setae are short, feathery, and eight in number...................[H. howletti]
3.
Ventral spur of palpal segment III is very small and not reaching to intersegmental suture;
infrainternal setae are very short and three to four in number; coxa I to IV are each with
very short ridge-like projection...................[H. megalaimae]
Ventral spur of palpal segment III extending slightly beyond intersegmental suture; infra-
internal setae are six to eight in number, short, well spaced; coxa I to IV are each with
short, broadly triangular spur...................[4]
4.
Palpal segment II appearing somewhat broken at mid-length in lateral profile; ventral
spur of palpal segment III is broadly triangular and extends slightly beyond intersegmen-
tal suture; infrainternal setae number six; spurs of coxa are short and blunt; trochanter
bears no or obsolete spurs...................[H. doenitzi]
Palpal segment II shows flared salience; ventral spur is short and extends only to interseg-
mental suture; infrainternal setae number seven; spurs of coxa and trochanters are moder-
ate and apex is pointed...................[H. minuta]
Females
1.
Basolateral margin of palpal segment II is rounded and the lateral profile of palpal seg-
ment II is little extended beyond the lateral margin of basis capituli...................[2]
Basolateral margin is straight and the lateral margin of palpal segment II is extended
more than half of its basal
length beyond the lateral margin of the basis capitu-
lum...................[3]
2.
The ventrobasal spur of palpal segment III is very acute, sharp, and extending beyond
half or two-thirds of palpal segment II; infrainternal setae are long, well spaced, lanceo-
late, and five to six in number; dental formula is 4/4; coxa I and trochanter I are larger,
while the spurs on other coxa and trochanters are very short or obsolete...................
[H. ornithophila]
Palpi are very compact; the ventrobasal spur of palpal segment III is broadly triangular
overlapping to half of palpal segment II; infrainternal setae are eight, short, feathery, and
closely spaced; dental formula is 5/5; coxal and trochanter spurs are blunt and
short...................[H. howletti]
3.
Palpi are spread; salience is very broad; palpal segment II is extending laterally more
than half of its basal breadth; ventrobasal spur on palpal segment III is very short or obso-
lete, infrainternal setae number three, short, and feathery; porose areas are circular and
not inclined...................[H. megalaimae]
Palpi are compact; salience is moderately broad; infrainternal setae number six to eight;
ventrobasal spur of palpal segment III is moderate or long in length; porose areas are
inclined to inner side...................[4]
4.
Salience is flared and extends a little beyond lateral margin; the ventrobasal spur on pal-
pal segment III is reaching to intersegmental suture; infrainternal setae are seven in num-
ber, short, and closely spaced with feathery outlook; porose areas are oval and more
inclined to inner side...................[H. minuta]
Palpi are compact and form a triangular-shaped capituli; salience is very much flared
dorsally; ventrobasal spur of palpal segment III extends very short to intersegmental
suture; infrainternal setae are seven or eight in number, closely spaced, feathery; porose
areas are small and inclined a little to inner side margin...................[H. doenitzi]
