Systematic position.
Teloganodes
belongs to the taxon
Ephemerella/fg1
, or superfamily
Ephemerelloidea
, which is characterized by peculiar structure of tergalii with lamellate dorsal lobe and two-branched ventral lobe bearing processes on outer sides of its branches (character 7 of Ephemerella/fg
1 in
Kluge 2004: 294
) (
Figs 1
,
50–57
), presence of crossvein
cua-cup
near base of fore wing (character 6 of Ephemerella/fg
1 in
Kluge 2004: 293
) (
Fig. 94
), certain reductions in larval maxillae and labium (characters 1–3 of Ephemerella/fg
1 in
Kluge 2004: 293
), peculiarities of larval thorax (characters 4–5 of Ephemerella/fg
1 in
Kluge 2004: 293
), loss of 4th segment of gonostylus (character 8 of Ephemerella/fg
1 in
Kluge 2004: 294
) (
Figs 42
,
97
), and some other characters (characters 9–19 of Ephemerella/fg
1 in
Kluge 2004: 294–295
).
The holophyletic taxon Ephemerella/fg1 is divided into two holophyletic taxa, Ephemerella/fg2 (or family
Ephemerellidae
) and Pantricorythi Kluge 2014, or
Tricorythus
/fg1 (usually treated as two or more families).
The taxon
Pantricorythi
is characterized by retention of fully developed tergalii on the 2nd abdominal segment (
Figs 1
,
62
), long 1st segment of the 3-segmented gonostyli (
Figs 42
,
97
) and peculiar arrangement of setal rows on anterior (dorsal) side of larval fore femur, which have a regular row crossing the femur near its middle and continuing distally along the outer margin of the femur (
Figs 19–20
). Among
Teloganodes
s. l.
, this arrangement of setal rows occurs in most species; in the known species of subgenus
Teloganodes
s. str.
, the transverse setal row of fore femur is either secondarily lost (
Sartori
et al.
2008
: fig. 59–60) or detached from the row on outer margin (
Selvakumar
et al.
2014
: fig. 50).
The taxon Pantricorythi contains

Dicercomyzon

Machadorythus

, the taxon with the non-typified circumscriptional name Tricorygnatha
Kluge 2004
and the large taxon with the rank-free hierarchical name Leptohyphes/fg1 (
Kluge 2004
).
Various authors either arrange these taxa among the families
Tricorythidae
Lestage 1942
and
Ephemerellidae
Klapálek 1909
, or accept greater number of families. In the past, the genus
Teloganodes
was placed in the family
Ephemerellidae
, which was paraphyletic in such sense. Currently, it is used to place
Teloganodes
in a family
Teloganodidae
Allen 1965
, which has no generally accepted circumscription and diagnosis.
