1.
Palpi are elongate without broadening of palpal segment ......... 2
Palpal segment broadened either in adults or immature stages...... 5
Palpal segment broadened in both adults and immatures, capitular spurs are less
developed ........... 3
Posterodorsal margin of palpal segment III with distinct or indistinct spur in one
or both sexes, or with platelike projections; posteroventral spur moderate to promi-
nent, triangular or hooklike, overlapping of anterior or whole part of palpal
segment II ............. 4
2.
Basis capitulum short and laterally convex with no cornua, dental formula 3/3 in female
while 2/2 in male and immatures, coxal spurs are small or obsolete, genital aperture is
slitlike .................. Alloceraea
Adult basis capitulum is variously shaped and armed with variable cornua,
some nymphs and larvae bear large coxal spurs, the adult palpal bears small ventral
spurs ..... Allophysalis
3.
Absence
or mild
development
of
spurs
on
capitulum,
coxa,
and
trochanters ..................... Ornithophysalis
Coxal and trochantal spurs are well developed, the basis capitulum has small to large
cornua.................. Rhipistoma
4.
Posteroventral spur on palpal segment III is moderate to extraordinary, posterodorsal mar-
gin of palpal segment III with distinct or indistinct, median or internal spur, cornua and
coxal spur broadly or elongately triangular, coxa IV sometimes with extraordinarily long
spurs in one sex ............ Kaiseriana
Posteroventral spurs of palpal segment III broadly triangular, overlapping anterior 1/3rd
of palpal segment II, posterodorsal spur on palpal segment III is absent, coxal spurs are
short, broadly triangular .............. Haemaphysalis
5.
Palpal segment broadened in adults only........... 6
Palpal segment broadened in immature stages only ................ 7
6.
Adult palpi are campanulate in male and broadly campanulate in female, capitular and
coxal spurs are moderately large and well developed............ Segalia
Capitular spurs are much reduced ........... Aborphysalis
7.
No lateral expansion of basis capituli in immature stages, palps are compact but are
slightly salient in nymphs of some species, adults and immatures have rectangular basis
capituli, adult cornua are moderately large to large in males and obsolete or small in
females................. Herpetobia
In certain species adults show a tendency to broad palpi, lateral expansion of basis capitu-
li of immature stages, immatures stages palps compact............... Aboimisalis
