2.4.2 Haemaphysalis nepalensis
This species was first described by Hoogstraal in 1962. The specimens were origi-
nally collected off white-bellied rats in the Leucopani area of Nepal in 1960 by
R.L. Fleming; hence, the name of the species is after the place of collection

Overall body length measures approximately 2.6 mm, width 1.6 mm.
Capitulum: Capitulum is approximately 0.5 mm in length. Cornua are fairly
widely triangular, approximately 0.35 as long as the base. Ventrally with short,
broad, medially directed retrograde spur on segment III. Hypostome lateral margins
are parallel; dental formula is 4/4, with maximum nine to ten denticles per file.
Scutum: Scutum is approximately 0.7 as wide as long, widest at the level of
coxa IV. Lateral grooves are very short, extending only to the level of coxa IV and
enclosing only first pair of festoons; cervical grooves are short, narrow, moderately
deep, comma-shaped; punctations are superficial, irregularly sized and distributed,
