Males
1.
Coxal and capitular spurs are absent or very small, only two infrainternal setae are pres-
ent, and dental formula is 4/4...................[H. nepalensis]
Coxal and capitular spurs are moderate, six to nine infrainternal setae are present, and
dental formula is 5/5 to 7/7...................[2]
2.
Coxa IV spur is lanceolate; moderate spur on coxa I and conventionally triangular but
variable spurs on coxa II and III; posteroventral spur on palpal segment III is short and
inwardly directed; nine or more infrainternal setae are present; dental formula is 5/5 or
4/4...................[H. sulcata]
Coxal spurs are hook-like or conventionally triangular; capitular spur is short and broad;
infrainternal setae number six to eight; dental formula is 5/5 or 6/6...................[3]
3.
Coxal spurs are hook-like; dental formula is 6/6; infrainternal setae are seven or eight in
number; body is elongated in shape; numerous; punctations are deep, lateral grooves are
long and enclose festoon(s)...................[4]
Coxal spurs are triangular; dental formula is 5/5; infrainternal setae number six; body is
oval in shape; number of punctations are moderate and are superficial; lateral grooves are
small or absent...................[5]
4.
Posteroventral spur on palpal segment III is broad and overlaps up to mid-length of palpal
segment II; infrainternal setae number eight; cornua are long and pointed; all coxal spurs
are hook-like and elongated...................[H. kashmirensis]
Posteroventral spur on palpal segment III is broad but just crossing the intersegmental
suture between palpal segment II and III; infrainternal setae number seven; cornua are
moderate but blunt or with rounded apical margin; all coxal spurs are hook-like but coxa
I and IV spurs are elongated than coxa II and III...................[H. kumaonensis]
5.
Coxal spurs are conventionally triangular on II to IV but appear to be spatulate or
bluntly triangular on coxa I; posteroventral spur on palpal segment III is broadly tri-
angular but reaching just short of suture between palpal segment II and III; puncta-
tions are numerous but irregularly sized and distributed; lateral grooves are very
small and enclose just one festoon, reaching to the base of coxa IV...................
[H. Himalaya]
Coxal spurs are triangular but elongate on coxa I, while short but pointed on others; pos-
teroventral spur on palpal segment III is broadly triangular but large, reaching to mid-
length of segment II; punctations are numerous but regular in size and distribution; no lat-
eral groove is present...................[H. sundrai]

1.
Coxal spurs are ridge-like or obsolete; posteroventral spur on palpal segment III is small
or absent; infrainternal setae are two in number; dental formula is 4/4; porose areas are
sub-circular in shape; external genitalia is sub-circular...................[H. nepalensis]
Coxal spurs are moderate to very small; posteroventral spurs on palpal segment III are
moderate and inwardly directed; infrainternal setae numbering range from five to eleven;
dental formula is 4/4 to 7/7; porose areas are circular or oval...................[3]
2.
Coxal spurs are very small; posteroventral spur on palpal segment III is triangular but
blunt and reaches to the suture between palpal segment II and III; infrainternal setae
