Material examined.
Holotype: female, HNHM Astig-242, Szarvas, 8 October 1968, from
Picea excelsa
Lk. No. 1250, Bozai, J. coll.
Diagnosis
(based on female). Anterior margin of prodorsal shield with forked projection; prodorsum smooth medially, with some striae laterally; anterolateral projections carrying setae sc2 weakly formed. Opisthosoma smooth anteriorly, with posteromedial reticulation and posterolateral longitudinal striation. Propodosomal setae as follows: v2 short and smooth, sc1 broad and obovate, sc2 long and phylliform. Opisthosomal setae: c1, c3 and d1 broad, long, oblanceolate, d3 short and oblanceolate, e1 short and smooth, h1, f1, f2 and e3 long, oblanceolate, h2 very long and smooth. Rostrum extending to middle of tibia I. Genital flap smooth. Intercoxal area
between
3a and 4a smooth, 1a and 4a very long, 1b, 2b, 2c, 3a, 3b, 4b, ag, g1, g2 short. Legs with large, broad and phylliform, smooth and pilose setae.
Description
(female holotype). Colorization of idiosoma not observable in the holotype. Idiosoma (Figure 27) pentagonal in shape, body measured from v2 to h1 305; from tip of rostrum 350; width between setae sc2 190.
Dorsum
(Figure 29): Anterior margin of prodorsal shield with paired projections, depth of notch 16. Prodorsum smooth medially, with some striae laterally; anterolateral projections carrying setae sc2 weakly formed. Opisthosoma smooth anteriorly, with posteromedial reticulation and posterolateral longitudinal striation. Propodosomal setae as follows: v2 short and smooth, sc1 broad and obovate, sc2 long and phylliform. Opisthosomal setae: c1, c3 and d1 broad, long, oblanceolate, d3 short and oblanceolate, e1 short and smooth, h1, f1, f2 and e3 long, oblanceolate, h2 very long and smooth. Rostrum extending to middle of tibia I. Opisthosomal pores between d1 and e1. Length of dorsal setae: v2 9-10, sc1 30-32, sc2 65, c1 45-46, c3 32-34, d1 38-40, d3 12-14, e1 12, e2 45-47, f2 and f3 45-46, h1 36-37, h2 105-110.

Venter (Figure 30): Very few striations observable in the holotype, only a few longitudinal striations visible posterior to g1-g2. Genital and anal plates smooth. Length of ventral setae, 1a 120-122, 3a 26-27, 4a 130-133, 1b 16, 2b 16-17, 3b 18-19, 4b

Gnathosoma: Rostrum extending to middle of tibia I; palp setal counts as in Figure 31.
Legs: Setal formula for leg
I-IV
(coxae to tarsi): 3-1-4-2-5-9, 2-1-4-2-4-9, 2-2-2-1-3-5, 2-1-1-0-3-5. Shape of the setae on legs illustrated on Figures 32-35.

Notes.
Bozai's
(1970)
noted in his detailed description of
Tenuipalpus szarvasensis
, that the species is very similar to
T. cheladzeae
, but he mentioned some easy to observe differences (like shape and length of setae c1, d1) between these two species. Despite these known differences,
Mitrofanov and Strunkova (1979)
synonymized the name under
Tenuipalpus cheladzeae
.
Mitrofanov and Strunkova (1979)
did not study the type specimens of
T. szarvasensis
, therefore their opinion was questionable.
This year, we studied the types of
Bozai's
T. szarvasensis
in order to confirm
Bozai's
hypothesis that
T. szarvasensis
differs from
Gomelauri's
T. cheladzeae
. The differences are presented in Table 3 and are illustrated in Figures 36, 37.
Tenuipalpus
is the largest genus of flat mites, but very few are known from
Pinaceae
. Apart from the above-mentioned two species, the only other species is
T. hondurensis
Evans, in
Evans et al. (1993)
(
Mesa et al. 2009
), which is considerably different from both the above species.
Tenuipalpus cupressoides
Smith, Meyer & Gerson, 1980 is very similar to
T. szarvasensis
, but the shape of v2 and e2 and the length of sc1, c1 and d1 are different. In addition, the host plant,
Cupressus sempervirens
of
T. cupressoides
belongs to the family
Cupressaceae
and not to
Pinaceae
(
Ueckermann et al. 2018
).
