Material examined
.
Spain
, Segovia, Sierra de Guadarrama, Eresma stream (
40º50.590' N
,
4º01.657' W
),
29.v.2012
and
19.vi.2012
, 1/1/0 (mounted), 2/2/0 in voucher collection for
LSCM
and molecular study.
General features
. Shoulder platelets fused to dorsal plate, but suture line visible; area of primary sclerotization of the dorsal plate with two dorsoglandularia; posterior suture line of Cx-4 indistinct; postgenital area large; excretory pore and Vgl–2 posterior to the line of primary sclerotization; distal margins of P-2 and -3 without denticles, ventral protuberance of P-4 unpaired, with one longer, and three shorter hairs; capitular rostrum (
Figs. 5D, F
) relatively long and slender (L/H ratio 2.0–2.4).

Remarks
. After the original description (
K.Viets 1930
), only one further record was published by
Lundblad (1956)
who showed that the male allotype of
T. lundbladi
designated by K.Viets was not conspecific, but represented
T. ungeri
. Our specimen from Segovia (
Spain
) agrees well with the description of
T. lundbladi
by
Lundblad (1956)
for the male and by
K. Viets (1930)
for the female.
Habitat.
Rhitrobiont; sandy/bouldery streams with well developed riffle areas (
Fig. 10
).
Distribution
.
Spain
(
