(Šámal, 1939)
SYNONOMY
Alloperla teleckojensis
Šámal, 1939
Suwallia teleckojensis
Zwick et al., 1971
TYPE LOCALITY:
Original
type destroyed (
Zwick
,
Levanidova
&
Zhiltzova
1971),
paratypes
recognized from
Russia
in the
Baikal region
.
DIAGNOSIS:
The pronotum is light with a well-defined brown band around the periphery of the pronotum and a dark medial stripe (
Fig. 126
), both of theses dark areas being thicker in comparison to
S. kerzhneri
(
Fig. 122
). The dark abdominal stripe of
S. teleckojensis
is wide and typically terminates at the posterior margin of sternum 8 (
Fig. 126
). Males have medially directed hemitergal processes (
Fig. 127
) which are cylindrical in cross section, not flattened or pointed as in
S. kerzhneri
(
Fig. 123
). The knob of the male epiproct (
Fig. 127
) is completely covered with fine hairs, as opposed to that of
S. kerzhneri
which only has hairs along its margins (
Fig.123
). The female subgential plate with dark basal sclerites where it is broadly joined at abdominal segment 8 (
Fig. 128
), and not basally incised as with
S. kerzheri
(
Fig. 124
). The plate gradually tapers and extends to the posterior margin of sternum 9. The head of the nymph has distinct dark pigmentation between and anterior to the lateral ocelli (
Fig. 129
), extending throughout the frons and labrum.

DISCUSSION:
Levanidova and Zhiltzova (1979, 1976) attribute the restriction of
S. teleckojensis
to mountains in the southern reach of its range and to foothill rivers in the northern reach as a product of the species inability to adapt to climate change. Likewise, our field collections were restricted to higher elevations and our ENM model indicates that
S.teleckojensis
is not expected to occur in non-mountainous regions (
Fig. 130
).
