Tanytarsus
van der Wulp
(
Fig. 103–108
)
Head capsules yellow to brownish with dark brown to black occipital margin. Occipital plate present, well developed. Antenna placed on tall pedestal (2–3 times as long as broad), usually without distal tooth or spur (if present, it is of different shape as in
Micropsectra
, see
Brooks
et al
. 2007
). Lauterborn organs usually on long pedicels. Premandible with 3 (usually) to 5 apical teeth. Mandible with 2–3 inner teeth, 1–2 dorsal teeth and in some species/ morphotypes 1–2 surficial teeth may be present additionally. Mentum with a single rounded or laterally notched median tooth and 5 pairs of lateral teeth. Ventromental plates narrowly separated medially, long, narrow and fine striated.
Remarks: As mentioned above, there are considerable difficulties to distinguish head capsules of
Tanytarsus
from
Micropsectra
and, to a lesser extent, from
Paratanytarsus
(see comments to
Micropsectra
and
Paratanytarsus
).
Five
Tanytarsus
species were confirmed in the Tatra Mts. lakes:
Tanytarsus bathophilus
Kieffer, 1911
,
T. gibbosiceps
Kieffer, 1922
,
T. gregarius
Kieffer, 1909
,
T. nemorosus
Edwards, 1929
and
T. pallidicornis
(Walker, 1856)
(
Bitušík
et al
. 2006a
;
Giłka 2007
).
Three morphotypes were distinguished following
