Keys to Identify Species of Subgenus Kaiseriana
Males
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 is present or ridged dorsobasal on palpal segment III;
coxa I shows large spur but others have small spurs or ridges.................................[4]
2.
Ventrobasal spur on palpal segment II is well developed; infrainternal setae number
four; ventrobasal spur of palpal segment III reaches or overlaps to two-thirds of palpal
segment II, presence of single elongate; lanceolate or dagger-like spur on coxa
IV...................................................................................................[H. spinigera]
Ventrolateral spur on palpal segment II is low or obsolete; infrainternal setae number
five; ventrobasal spur on palpal segment III reaches to half of palpal segment II, pres-
ence of two long spurs on coxa IV...................................................[3]
3.
Shallow and medium lateral groove is extending up to coxa III; evenly scattered puncta-
tions are evenly scattered; both spurs on coxa IV are posterolaterally directed and well
spaced, the outer one is needlelike long while the inner is smaller; trochanters ventrally
show small and triangular spur...................[H. shimoga]
Deep and long lateral grooves are extending up to coxa II; punctations are irregularly
scattered; both the spurs on coxa IV are posteroexternally directed, closely spaced, and
approximately equal in size; trochanters ventrally have no spurs...................[H. anomala]
4.
Cornua are well developed with enlarged posterodorsal spur...................[5]
Cornua are very small with small to moderate posterodorsal spur on palpal segment III,
in some cases posterodorsal spur is triangular or curved; coxal spurs are well developed
to reduced...................[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, and extending beyond palpal
segment II and externally directed; infrainternal setae number four; dental formula is
4/4; lateral grooves are moderate in size and extending up to anterior of coxa III without
enclosing any festoon;
spurs on coxa I and trochanter are pointed...................
[H. cuspidata]
Palpal segment II is larger than palpal segment III, dorsal and ventral spurs on palpal seg-
ment 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 num-
ber five; dental formula is 5/5; lateral grooves are small and extending up to only anterior
of coxa IV and enclosing first festoon on both sides; spurs on coxa I and trochanter I are
spatulate...................................................................................[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 two-thirds of palpal segment III
ventrally and present in mid-line; infrainternal setae number six; dental formula is 6/6;
punctations are numerous, small, and evenly distributed; coxal spurs are large, pointed;
only trochanters I and II have short, triangular spurs ventrally...................[H. davisi]
Spurs on palpal segment III posterodorsally and posteroventrally are large, reaching
almost half 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; infrainternal setae
number five; punctations are small, numerous and irregularly scattered, and shallow; lat-
eral groove is medium length, not enclosing any festoon; coxal spurs are triangular and
look blunt...................................................................[H. ramachandrai]
