of Kathmandu) toward and near the Tibet border. Ecologic features of Langtang
valley, Melumche, and Gosainkund, three of the five localities where H. (A.)
warburtoni as collected in Nepal, have been described by Hoogstraal and Mitchell
(1971).
Related Species
A closely related species is H. garhwalensis. Posteroventral spur on palpal segment
III is small, broadly triangular, slightly elevated, not reaching to posterior margin
of palpal segment III in H. garhwalensis, whereas in H. warburtoni the spur is
reaching to the anterior of palpal segment II and inwardly directed. Coxal spurs of
H. warburtoni are stouter and stronger compared to H. garhwalensis.InH. warbur-
toni, all trochanters have crest-like spurs, while in H. garhwalensis only trochanter
I has a crest-like spur.
2.3 Subgenus Aboimisalis
General Characteristics
It includes four species, viz. H. cornupunctata, H. punctata, H. chordeilis, and
H. cinnabarina. Among these only H. cornupunctata has been recorded in India.
Immature palpi are compact, lacking salience in H. cornupunctata but are slightly
salient in H. punctata and H. chordeilis, and the ventral spur is slight or obsolete.
Adult palpi are quite compact, slightly broader than in the few males of earlier sub-
genera in which the palpi tended to be more compact. It can be observed that,
under the structurally primitive (SP) Haemaphysalis category, adults of Aboimisalis
are structurally more advanced and show a slight step in generic trend to broad
palpi. Cornua exist in males of all species, but in females only in H. cornupunctata.
Dental formula of adults is from 4/4 to 6/6 and in immatures 2/2. Coxal spurs are
moderate sized in females, but male coxa I to III spurs are much reduced and coxa
IV spur is very long and lanceolate.
Keys to Identify Species of Subgenus Aboimisalis
Male
Salience is medium as the convex basal margin of palpal segment II and compact
palpi; basis capituli are rectangular; dental formula is 4/4 or 5/5; posterodorsal spur
is absent; posteroventral spur is short, wide, blunt, reaching to intersegmental
suture of palpal segment II and III; infrainternal setae are closely spaced, short,
feathery, and number 11; punctations are few, superficial, and irregular in size and
distribution; lateral grooves are long and superficial, reaching to coxa II, enclosing
first two festoons; coxa IV bears a very long, lanceolate, and pointed spur, while
coxa I to III spurs are reduced...................[H. cornupunctata]
