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 Vietnamella Tshernova 1972, Austremerella Riek 1963, Ephemerellina Lestage 1924, Lithogloea Barnard 1932, Lestagella Demoulin 1970, Nadinetella McCafferty & Wang 1998, Manohyphella Allen 1973, Indoganodes Selvakumar et al. 2014, Melanemerella Ulmer 1920, Teloganella Ulmer 1939, Teloganodes Eaton 1882, Ephemerythus Gillies 1960, Dicercomyzon Demoulin 1954, Machadorythus Demoulin 1959, 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.
