Subtribe EUTERPNOSIINA Lee, 2013

Euterpnosiina Lee, 2013 in Lee and Emery, 2013: 527–528.

Remarks

The position of the new genus described immediately below is unique and independent from any other known species of Leptopsaltriini in the phylogenetic tree constructed by Hill et al. (2021). Therefore, this genus could form a separate new subtribe within Leptopsaltriini . This genus has very long fore wing apical cells, which is one of its peculiar characteristics within Leptopsaltriini , and has tubercle-like projections only on the sternite III, which is seen only in some members of Tanna Distant, 1905 and Vietanna Lee and Pham, 2021 . This genus is different from the genera of Puranina Lee, 2013 because of the anterolateral pronotal collar which is not dentate, the male abdominal sternite IV which does not have tubercle-like projections, and the aedeagus which is thick apically.

This genus is tentatively placed in Euterpnosiina because the type specimen of the genus was largely grouped with genera of Euterpnosiina in the phylogenetic tree constructed by Hill et al. (2021) in spite of many morphological differences, including the following: timbal cover well developed (vs minute in Euterpnosiina ); male abdominal sternite III with tubercle-like projections (vs mostly without them in Euterpnosiina ); aedeagus thick (vs thin in Euterpnosiina ); and basal lobe of pygofer absent (vs present in Euterpnosiina ). Further taxonomic study is required to find its proper subtribe placement.
