Notophthiracarus lineatus
sp. n.
Fig. 1
Etymology: From the Latin
lineatus
(streaKed, marKed with lines) and alludes to the foveoles on the notogastral surface joined with lines.

=0.8, genitoaggenital plate 114×71, anoadanal plate 114×66.
Integument
. Colour light brown. Integument very finely foveolate, foveolae on notogaster joined with weaK lines.
Prodorsum
(
Fig. 1A, B
). Lateral carinae weaK. Sigillar fields distinct, median slightly dilated in distal part, considerably longer than lateral fields. Sensilli long, with thin stalK and dilated head with tips covered with small spines. Interlamellar setae long, thick, erect covered with small spines in distal part, similar in shape to notogastral setae. Lamellar and exobothridial setae minute. Rostral setae spiniform and rough.
Notogaster
(
Fig. 1C, D
). Notogastral setae of medium length (

<
c

), thicK, covered with small spines in distal part. Setae
c

and
c

slightly remote from anterior margin of notogaster, setae

far from notogastral margin. Vestigial setae not discernible. Two pairs of lyrifissures

and

present.
Ventral region
(
Fig. 1E–G
). Formula of genital setae: 6:3. Anoadanal plates each with five setae; adanal setae
ad

longest and thicKest, obtuse distally; adanal setae
ad

longer and thicKer than anal setae, all these setae rough; adanal setae

minute, smooth.

from the same locality, MAG-208 (ISB). Remarks: The new species is readily distinguishable by the foveolated surface of the body joined by weaK lines, the dilated median sigillar field of the prodorsum and the shape of the sensilli with heads ciliated at the end.
N. lineatus
is slightly similar to

but the interlamellar and notogastral setae of
N. lineatus
are not dilated at the distal half, sensilli do not have a club-like head, the formula of genital setae is 6:3 (versus 5:
4 in
N. similis
) and
ad

setae are attenuated (versus
ad

of equal width in

) (Niedbała 2001).
