and feathery; moderate lateral groove enclosing first festoon, extending to coxa III; tro-
chanters show spurs ventrally..................................[H. paraturturis]
Dorsobasal spurs of palpal segment III are absent or crest-like; infrainternal setae are
seven in number, widely spaced, lanceolate, or feathery; lateral grooves are long, enclos-
ing first festoon and extending up to coxa II; punctations are numerous but are widely
scattered; trochanter spurs are absent..................................[H. silvafelis]
Keys to Identify Females
1.
Palpi are broadened; dorsal spur on palpal segment III is absent, all coxa bear long spurs
but variable in length...................................[2]
Palpi are campanulate, dorsal spur present or dorsobasal spur on palpal segment III is
ridged; coxa I
sometimes
shows
large spur but others have small
spurs or
ridges...................................................................................................[4]
2.
Ventrolateral spur on palpal segment II is well developed; infrainternal setae number
four; ventrobasal spur of palpal segment III reaches or overlaps to half of palpal segment
II; porose areas are more or less circular and widely spaced; coxa I spur is moderate and
thin, while other coxa bear small spur........................................................[H. spinigera]
Ventrolateral spur on palpal segment II is low or obsolete; infrainternal setae number
five or more; coxa I spur is moderate to long in length and decreases in size from coxa
II onward...................................................................................................[3]
3.
Infrainternal setae are five in number but short; porose areas are oval but small; coxa I
shows a very long, pointed spur, while other coxa bear small and more or less equal-
sized spurs; trochanters ventrally show small, triangular spur...................[H. shimoga]
No ventrolateral spur on palpal segment II; infrainternal setae are eight in number and
are long; porose areas are oval and big; punctations are irregularly scattered; coxa I spur
is long but blunt, while others are broadly triangular or ridge-like; trochanters ventrally
have no or obsolete spurs...................................................[H. anomala]
4.
Cornua are well developed with enlarged posterodorsal spur...................[5]
Cornua are very small or moderate with small to moderate posterodorsal spur on palpal
segment III................................................................................................................[6]
5.
Palpal segment II and III are nearly equal in length; dorsal and ventral spurs of palpal
segment III are sharply triangular, tapering to acute apex, extending up to the base or
beyond palpal segment II and externally directed; infrainternal setae number four; dental
formula is 4/4; spurs on coxa I are pointed, while other coxa bear ridges; trochanter I
bears a spatulate spur...................................................................[H. cuspidata]
Palpal segment II is larger than palpal segment III; dorsal and ventral spurs on palpal
segment III are broadly triangular, reaching to two-thirds of palpal segment II dorsally
and up to one-third ventrally; laterally directed; infrainternal setae are long, lanceolate,
and number four; dental formula is 5/5; spurs on coxa I and trochanter I are spatu-
late...................................................................................[H. aculeata]
6.
Spurs on palpal segment III are conventionally triangular, moderately large and overlap-
ping about one-third of palpal segment II dorsally and one-half of palpal segment II ven-
trally, and present in mid-line; infrainternal setae number five; dental formula is 5/5;
punctations are numerous, small, and evenly distributed; coxal spurs are moderate,
pointed on coxa I, and blunt on others...................................................[H. davisi]
7.
Spurs on palpal segment III posterodorsally and posteroventrally are large, reaching
almost one-third of segment II dorsally while two-thirds or more of segment II ventrally
and present in the mid-line and curved outwardly; dental formula is 4/4; porose areas
