Ixodes rubicundusy Neumann (1904). 
Plate I V, figures l (a, b). 
Male. — Body, 2.3 mm. (including rostrum) with an oval contour, 
narrower in front, 1.2 mm. wide, near the posterior third; chestnut 
brown. Shield convex, shining, glabrous, leaving a marginal cushion 
■ exposed, which is wider behind than on the sides, and from which 
it is separated by a deep groove ; cervical grooves straight, superficial, 
prolonged and diverging near the middle of the length ; no posterior 
festoons; numerous punctuations, small, unequal, regularly 
distributed. On the ventral surface [/ V, l (a)] genital pore wide, 
between the coxae of the third pair of legs ; pregenital shield long, 
triangular ; genito-anal shield pentagonal, much longer than wide, 
with shallow punctuations, not very numerous ; anal shield 
rectangular, with sides parallel, longer than wide, very finely 
punctured, adanal shields longer than wide, with sides parallel ; no 
hairs ; stigmatic plates large, circular. Rostrum short ; base 
trapezoidal, larger in front, and wider than long, its posterior angles 
not salient on the dorsal surface, but so on ventral surface, separated 
by a similarly salient median pair ; mandibles thick, inner apophysis 
with two strong teeth, the posterior stronger; outer apophysis with 
three teeth, the anterior small, the posterior very strong; hypostome 
[/ 1, l (5)] wide, teeth fused on each half into four transverse 
crenulations with three or four denticles, followed by a row of four 
or five teeth, and on each side with a very strong tooth ; palpi short, 
the second and third articles almost of same length. Legs of medium 
length, brick red; coxae I with inner spine almost obsolete; the other 
coxae unarmed; tarsi of medium length, progressively attenuated. 
Female.. — Body in an elongate oval, may reach 10 mm. in length 
(rostrum not included) by 6.5 mm. wide at the posterior third, brick 
red on specimens of a small size, but chestnut coloured on others. 
Shield in a short oval, scarcely longer (1.6 mm.) than wide (1.4 mm.)., 
with lateral edges a little convex and diverging from front to rear, 
then a right angle converging to form the posterior angle, which is 
rather narrow, anterior margin a little emarginate for the insertion 
of the rostrum ; cervical grooves well marked ; almost reaching the 
lateral margins ; lateral grooves very pronounced ; punctuations 
numerous, fine, slightly unequal, few in the lateral areas; surface 
shiny, glabrous, chestnut brown. Dorsal surface with scattered hairs ; 
punctuations very superficial; three posterior grooves. Ventral surface 
with punctuations and hairs similar ; genital pore opposite coxae IY, 
anus very anterior ; anal grooves long, parallel, united in front of the 
anus; stigmatic plates small, circular, whitish. Rostrum. 0.85 mm. 
long; dorsal base rectangular, much wider than long; porose areas 
oval, oblique, converging in front, situated near the lateral margin and 
separated by an interval equal to their width ; on the ventral surface 
a retrograde spine behind the insertion of each palpus; mandibles 
with inner apophysis elongate, parallel to the shaft; outer apophysis 
with five teeth increasing in size from tip to base; hypostome elongate, 
narrow sublanceolate, with three rows of teeth on each side, the 
median one short, and with six to seven teeth, the middle one almost 
as long as the external one, which extends from the tip to the base.
