Nonmonophyly of Nematopodini

A paraphyletic Nematopodini with respect to Spathophorini has also been supported by Kieran et al. (2019) and Forthman et al. (2019). However, in some of our analyses, Discogastrini was recovered within Nematopodini rather than as the sister group of Nematopodini + Spathophorini . This was not dependent on the analytical method or type of data set used. Thus, Discogastrini may render Nematopodini (including Spathophorini ) not monophyletic. To our knowledge, there are no previous hypotheses for a relationship between these three taxa.

Amyot and Serville (1843) included some members of Discogastrini within the Nematopodini based on the presence of enlarged, armed hind femora in males (although, in type images of several genera, the legs of Discogastrini appear slender and unarmed). Discogastrini was subsequently treated as a distinct group from the Nematopodini by Stål (1867), primarily due to the position of the abdominal spiracles. In his comparative morphological study, Schaefer (1965) included the Discogastrini , Homoeocerini , and Latimbini in his Homoeocerus -group (each tribe treated as a separate subgroup) based on the structure of the conjunctiva, metathoracic scent gland opening, laterotergites, and external genitalia ( Nematopodini not examined). Our results are more in line with Amyot and Serville’s (1843) classification, although the shape and armature of the hind femora may not be synapomorphies for Discogastrini + Nematopodini (including Spathophorini ).
